Soft Tissue Rheumatic Disorders
RoaaMahroos andHaniAlmoallim
22.1 Introduction
Soft tissue disorders are common focal pathologi-
cal syndromes affecting soft tissue structures like
tendons, ligaments, bursa, fascia, and the site of
insertions of these structures to bones (enthesis).
They are commonly encountered disorders in
daily clinical practice particularly in outpatient
settings. A systemic disease does not always
accompany them;, however, they can be associated
with spondyloarthritis. They are most likely
caused by overuse, repetitive trauma, and occupa-
tional history. This chapter will present in a simpli-
ed approach different types of bursitis, tendinitis,
enthesitis, and fasciitis encountered in clinical
practice. The emphasis will be placed on diagnos-
tic workup based on comprehensive history- taking
skills and musculoskeletal (MSK) examination
ndings. Outlines of management principles will
be reviewed as most of these disorders respond to
conservative therapy (pain management, physio-
therapy, and avoidance of aggravating movements)
and it rarely needs surgical intervention. There are
other soft tissue disorders discussed in “Diabetes
and Rheumatology” Chap. 21. Detailed techniques
of MSK examination of several of these disorders
are discussed in Chap. 2.
22.1.1 Learning Objectives
By the end of this chapter, you should be able to:
Discuss the anatomy and classication of
common soft tissue disorders (bursa, liga-
ments, tendons, and fascia) that cause local-
ized pain syndromes.
Describe the clinical presentation of the most
common types of soft tissue disorders.
Construct a diagnostic approach for different
types of soft tissue disorders.
Outline management principles of these
disorders.
22.1.2 Classication ofSoft Tissue
Disorders
A selective group of soft tissue disorders will be
reviewed in this chapter based on the following
classication (Fig.22.1). It is based on the site of
involvement of these structures. It is important to
consider soft tissue disorders in the differential
diagnosis of regional pain syndromes.

22.1.3 Bursitis
It is important to realize the anatomical denition
of a bursa in order to recognize the clinical pre-
sentation of bursitis. A bursa is simply the sac
structure that is formed of two layers lled with
synovial uid that protects other structure under-
neath it from injuries caused by pressure. This
sac acts as cushions. Bursitis is simply inamma-
tion of this sac.
The most common sites are shoulder (subdeltoid,
olecranon), hip (ischial tuberosity, trochanteric),
knee (prepatellar bursa), and foot (retrocalcaneal)
[19]. Table 22.1 represents a comprehensive a
general review of the clinical presentation, investiga-
tion, and treatment of bursitis. Table22.2 represents
a review of specic types of bursitis.
22.1.4 Tendinitis
A tendon is a thick brous cord that attaches
muscle to bone. Inammation in the tendon is
called tendinitis. The most common sites for ten-

Table 22.1 Review of the Bursitis history, physical examination, investigation, and treatment
History Pain: Assess duration, site, localization, increases with movement, relation to position,
interferes with activity, recurrence, other joint pains, stiffness, and functional disability (at
home, work, and leisure activities)
Occupation: Repetitive movement disorder that increase pressure in the joint and its
surrounding soft tissue structures. For example, overhead lifting, pushing up elbows when
arising from bed, carrying heavy objects, prolong sitting on hard surface, and repeated
kneeling
History of trauma: Systemic review for evidence of a systemic disease (see Chap. 1) like
rheumatoid arthritis (RA), crystal-induced arthritis (gout, pseudogout) and uremia
History suggestive of infection: Fever, (infective endocarditis, cellulitis), skin abrasions in
supercial bursae (olecranon and prepatellar bursa) wounds, and diabetic, alcoholic [57]
and immunosuppressed patients are at increased risk of septic bursitis [8, 9]
Obesity
Physical
examination
Swelling: Mainly supercial
Tenderness: With active range of motion (ROM) testing
Reduced active ROM: With less or no pain with passive ROM
Local tenderness: With palpation over the bursa
In septic bursitis: Fever, swelling, redness, tenderness, and hotness [10]
Investigations 1. If history and physical examination suggest septic bursitis
a. CBC, blood culture, and glucose
2. Bursa uid aspiration: [11]
Deep bursa use US or MRI guided aspiration, and uid for
a. Cell count:
Normal WBC: less than 200/ L.
Noninammatory WBC: 200–2000/ L.
Inammatory WBC: 2000–100, 000/ L.
Septic bursitis WBC: may be exceeding 100, 000/ L
b. Gram stain and culture in liquid media: [10] It is
Positive in two-thirds of patients with septic bursitis [8].
The most common organisms: Staphylococcus aureus In about 80% of cases, [8, 9, 12,
13] streptococci beta-hemolytic strain, rare coagulase negative staph, Enterococcus, E.
coli, and Brucella, or TB in subacute and chronic endemic areas
c. Crystal analysis utilizing compensated polarized microscopy
d. Bursa uid glucose: Serum glucose ratio of <50% [14]
3. Imaging typically not helpful in acute supercial bursitis:
a. Plain X-ray: When there is history of trauma or foreign body and to exclude crystal-
induced arthritis particularly chondrocalcinosis
b. CT or MRI: Particularly in septic bursitis to conrm the presence of abscesses or uid
collection

Table 22.1 (continued)
Treatment 1. Patient education
a. Avoid aggravating factors that increase joints pressure
b. Joint protection program using cushion and pads
c. Rest joint position to decrease pressure
d. Weight reduction
2. Pain control and decrease inammation:
a. NSAIDs (see Chap. 4):
selective cyclooxygenase 2 inhibitor (celecoxib 200mg twice daily) or nonselective
(naproxen 500mg twice daily for few days in acute bursitis)
b. Local glucocorticoid injection:
after ruling out septic bursitis with negative culture
there is limited data on efcacy and safety;, in general it is more effective than NSAID in
speeding recovery, relieving pain, and preventing recurrence of olecranon and
subacromial bursitis [7]
long-acting glucocorticoid (methylprednisolone 40mg for large bursa, subacromial or
trochanteric, and 10mg for small bursa, anserine or Ischia) mixed with equal amount of
1% lidocaine
injection should not be repeated for 6–8 weeks
c. Apply ice for 20min 6–4 times per day
d. Heat not more than 20min
Septic bursitis:
treatment in immunocompetent or nondiabetic patients:
Oral antibiotic (dicloxacillin or second-generation cephalosporin or clindamycin) for 10
days if there is improvement
frequent aspiration of the bursa and continue antibiotic for 5days post sterilization
in severe cases and in immunosuppressed patients:
IV broad-spectrum antibiotic to cover pseudomonal plus anti-methicillin-resistant S.
aureus (MRSA) (vancomycin) for 2–3 weeks, till the culture and sensitivity results are
available [15]
repeat bursa drain and debridement or open surgical drain in deep bursitis
Table 22.2
Subacromial bursitis
Anatomy Subacromial bursa lies between acromion process and supraspinatus muscle at top of the
humorous
Bursitis results from inammation of supraspinatus tendon
Action of
supraspinatus
muscle
Abduction of the shoulder
Symptoms • severe pain at rest and movement of the affected shoulder
• prevent active movement
Signs • tenderness over the bursa just below the acromion
• this may extend over deltoid muscle
• tender and possibly restricted active ROM, while passive abduction is harmless with
possibility of mild tenderness
Treatment Pain is markedly relieved after injecting local anesthesia, immobilization, rest of the joint, and use
of NSAIDs
If not improving after 72 h, inject methylprednisolone 40mg with lidocaine
Comment It is associated with:
• rotator cuff tear that presents with supraspinatus muscle weakness
• polymyalgia rheumatic when it is usually bilateral
Scapulothoracic bursitis [24]
Anatomy The bursa is located in medial angle of scapula and adjacent to second and seventh ribs
Symptoms Pain and popping sensation with scapulothoracic movement
It increases with working overhead, pushing up, reaching up, and shoulder shrugging
Signs Localize tenderness and crepitus with movement
R. Mahroos and H. Almoallim

Table 22.2 (continued)
Treatment • spontaneous regression in most of the patients [1]
• physiotherapy: Postural and scapular strengthening exercise [2]
• US heat stretching test might help
• if pain persists, glucocorticoid injections under uoroscopy might be considered
• surgery might be indicated in refractory cases [3]
Olecranon bursitis (student’s elbow) [912]
Anatomy The bursa is located just over the extensor aspect of the extreme proximal end of the ulna
Aggravated
positions
Leaning on elbow, repetitive forward leaning position, or any position where pressure
is exerted on the bursa
Symptoms Pain in the posterior point of the elbow with normal ROM
Signs Tenderness, worsening of pain with elbow exion, and swelling in posterior point of the elbow
Treatment Consider bursal uid aspiration if swollen to rule out septic and/or crystal-induced bursitis
Treat underlying condition if sepsis or crystal-induced bursitis have been conrmed.
Glucocorticoid injection is superior to NSAIDs in preventing recurrent bursitis [4]
Referral to orthopedic surgery if recurrent with thick synovium
Ischiogluteal bursitis (Weaver’s bottom)
Anatomy The bursa is located between gluteus medius muscle and ischial tuberosity
Symptoms Pain in sitting and lying position. Also, pain in lower buttock after prolonged sitting
On hard surfaces
Signs Tenderness over ischial tuberosity
Treatment NSAIDs, glucocorticoid injection, foam rubber cushion, and stretching with knee to chest exercise
Greater trochanteric bursitis
Anatomy The bursa is located between the tendon of gluteus medius and posterolateral prominence of
greater trochanter
This bursitis is more common in females rather than males
Symptoms Night pain, lateral hip pain, 40% radiate to the lateral site of the thigh, worsening if lying on
affected side, and patient cannot walk in severe case
Iliotibial band syndrome (snapping hip) and leg length discrepancy predispose patients to develop
trochanteric bursitis
Signs • tenderness on lateral hip joint pain region over the greater trochanter
• hip joint resisted hip abduction may reproduce symptoms
• antalgic gait
Notes:
The differences between greater trochanteric bursitis and gluteus medius tendinopathy are gluteus
medius tendinopathy causes pain and tenderness superior to the greater trochanter, positive
Trendelenburg test, signicant muscle weakness, and positive one—Leg mini-squat test, patient
cannot complete a single repetition squat on affected leg to 60°
Recommended X-ray: Lateral, anteroposterior, and frog-leg views to rule out other causes
affecting hip joint itself
Treatment Radiating radicular pains from the lower back need to be ruled out as well.
Heat and passive stretching exercise with hip adduction can be tried with weight reduction and
avoiding stairs
Some resistant cases may need to be injected with glucocorticoid and lidocaine
Spinal needles should be used in obese patients
Prepatellar bursitis (Housemaid’s knee) [19]
Anatomy The bursa is located between the patella and the skin
Symptoms Positive history of kneeling down frequently and/or history of trauma
Anterior knee pain that increases with exion
Swelling may be observed
Signs Tenderness over the patella. Swelling, hotness, and redness particularly in septic or crystal-
induced bursitis
Treatment Rule out septic bursitis and/or crystal-induced bursitis with bursal uid aspiration
Rest joint and avoid trauma. Glucocorticoid injection may be considered
In refractory cases refer to surgery

dinitis are around shoulder, elbow, and ankle
joints. One of the pathophysiological mecha-
nisms for tendinitis is micro-tears, affecting these
tendons from repeated stressors like in overuse,
or in traumatic situations.
In some situations where there is inamma-
tion of the tendon sheath, the condition is called
tenosynovitis. Table 22.3 represents a compre-
hensive, general review of the clinical presenta-
tion, investigation, and treatment of tendinitis.
Table 22.4 represents a review of rotator cuff
tendinitis.
Tendinosis is a chronic proses associated with
an atrophic and degenerative change of the ten-
don caused by recurrent tendinitis. US or MRI is
required to diagnose it and to differentiate
between different causes.
22.1.5 Rotator Cu Tendinitis
andRotator Cu Tear
Rotator cuff tendinitis (RCT) is a common type
of tendinitis that affects the shoulder. The patient
usually presents with lateral shoulder pain and
limited active ROM.It is the most common cause
of shoulder pain in clinical practice. A brief
approach to shoulder pain is presented in Chap.
2. Table 22.4 represents a comparison between
RCT and rotator cuff tear (RCTr) in terms of de-
nition, diagnostic, and therapeutic interventions.
Table 22.2 (continued)
Anserine bursitis (Goose’s foot)
Anatomy The bursa is located medially around 6cm below the joint line at the attachment of medial
collateral ligament to medial tibia
It is the site of insertion of three tendons: gracilis, sartorius, and semitendinosus muscles
Symptoms Risk factors: Positive history of repeated knee exion in excessive running, stair climbing.
More common in obese elderly females and/or with valgus knee alignment
Pain at night over the upper tibia around 6cm below medial joint line
It is important to ask the patient to point with one nger the area of pain
Signs Local tenderness over the exact anatomical location of the bursa. Rule out medial collateral
ligament instability (see Chap. 2)
Treatment Rest. Repeated knee bending should be avoided;, also avoid crossing the leg or frequent squatting positions
Use pillow under the knee as a relaxation technique. Ice bags may be applied. NSAIDs can be used,
and if there is no improvement after 6–8 weeks, local glucocorticoid injection can be considered.
Gastrocnemius semimembranosus bursitis (Baker’s cyst)
Anatomy The bursa is located between gastrocnemius and semimembranosus muscles on the medial side
distal to the crease in the popliteal fossa back of the knee
Most common in adult from 35–70 years old, and it increases with age because the
communications between the knee and bursa increase [16]
Symptoms Asymptomatic accidental nding during physical examination or radiological investigation
Posterior knee pain and stiffness that increase with activity
Swelling or discomfort in prolong that standing and hyperexion
Signs Swelling in posterior aspect of the knee, more marked with knee extension
Absence of swelling on knee exion up to 45° (Foucher’s sign)
Ecchymosis below the medial malleolus (cresent’s sign) in rupture baker’s cyst
Causes One third of causes is due to trauma. Two thirds of the causes are due to other diseases
(osteoarthritis, rheumatoid arthritis, septic arthritis and meniscal tear)
Complication Pseudothrombophlebitis, leg ischemia, compartment syndrome, nerve entrapment, and ruptured [17]
Treatment Investigation by US or MRI
Treat underlying disease
If asymptomatic no treatment
In arthrocentesis and intra-articular corticosteroid injection result in decrease size after 4 weeks by
US follow-up [18]
Direct cyst injection if it does not communicate with the joint
Surgery is indicated in recurrences and lack of response to glucocorticoid injection

Table 22.3 Review of the tendonitis history, examination, diagnosis, treatment, and prevention
History Localized pain over the tendon with active movement particularly
Limited activity
Occupation: overuse and/or sporting activity, usually in middle age group of patients
Risk factors Intrinsic
• Age over 35 years and obesity
Biomechanical abnormalities: Mostly located in lower limbs (pes planus [at foot], pes cavus,
reduced planter dorsiexion, pelvic inequality and kyphosis)
• Previous tendinitis or rupture
• Fluoroquinolones use [19]
Extrinsic
• Training error (sudden increase and inadequate rest)
• Environmental (hard gym oors, frozen turf)
• Poor equipment (inappropriate footwear)
• Poor ergonomics excessive movement
Examination • Localized tendon pain
• Pain with tendon loading
• Pain with passive stretching
• Pain with active movement
• Normal ROM on passive test
• Muscle weakness in chronic tendinitis and tendon tear
Diagnosis US and MRI:
• Help to diagnose partial or complete tendon tear
• Tendon thickness
• To rule out other causes particularly if patient did not improve on treatment
Treatment • Avoid aggravating activity
• Apply ice over the tendon for 15min 4–6 times daily
• NSAIDs and local glucocorticoid injection in severe cases
Physiotherapy: Range of motion stretching and strengthening exercises, eccentric exercise, and
aerobic tness
• Surgery: probably after 6 months if no improvement or acute tendon rupture

hyperlipidemia), and Lifting heavy objects [19]. Acute tear can also occur with a fall or forceful
injury.
Symptoms • Shoulder pain increasing with overhead activity
• Shoulder pain could be laterally or posteriorly. It depends on the muscle involved
• Limited shoulder movement particularly active ROM.
• In the case of rotator cuff tear, muscle weakness is more pronounced, and patients can be
asymptomatic.

Table 22.5 History, examination, diagnosis, and treatment of enthesitis
Sites The common sites for enthesitis are in planter fascia at calcaneus and Achilles tendon in the heel.
However, there is a scoring system to measure the extent of enthesitis in different body sites
Causes Ankylosing spondylitis, reactive arthritis, psoriatic arthritis, inammatory bowel disease (IBD),
celiac disease, Whipple disease, acne-associated arthritis, fracture, trauma, and idiopathic
secondary usually to repetitive trauma or mechanical misalignment or over weight
History suggestive of SpA (see Chap. 1): Red eyes, pain with eyes movement, oral or genital ulcer,
genital discharge, back pain or other joint pain, diarrhea or bloody diarrhea resent gastroenteritis,
history of psoriasis, or family history of psoriasis
Symptoms Pain that increases with activity and possibly swelling
Signs • local tenderness increase with movement
swelling
warmth
• decrease active ROM and stiffness
other sites: Iliac crest, greater trochanter, medial and lateral epicondyles in elbow, tibial
tuberosities, plantus, costochondral junction, and humeral tuberosities
• Most enthesitis in SpA is not detected at clinical examination
Investigations Special test: HLA B 27
X-ray: Nonspecic nding: like intra-tendon focal edema, calcic deposit spars, soft tissue
swelling, and thickening
US: Better than clinical examination in the detection of enthesitis of the lower limbs in SpA.There
are specic radiographic denitions for enthesitis at different body sites
Treatment Exercise program
Proper shoe wearing using custom made devices
Occupation-related measures
Local steroid injection in severe and resistant cases
In SpA: NSAIDs can be tried rst, no clear evidence of efcacy for sulfasalazine [23]
and/or methotrexate [24] in enthesitis mainly presentation in SpA.However, several studies
showed efcacy of anti-TNF-alpha therapy and IL-17 antagonists in severe enthesitis [25]
22.1.6 Enthesitis
It is inammation at the site of insertion of ligaments,
tendons, fascia, and articular capsules into the bone.
It might be associated with pain at free nerve ending.
It is the hallmark of spondyloarthritis (SpA) particu-
larly when paravertebral ligaments are involved caus-
ing spondylitis. Extensive search for a systemic
spondyloarthritic disease (see Chap. 1) should be
sought in patients presenting with common enthesitis
like Achilles tendinitis and plantar fasciitis [21, 22].
However, most of these enthesitis disorders have no
systemic correlation, and they are induced by regional
pathophysiological mechanisms. Table 22.5 repre-
sents a review about enthesitis. Tables 22.6, 22.7 and
22.8 summarize common enthesitis encountered in
clinical practice: Achilles tendinitis, epicondylitis,
and plantar fasciitis (Table 22.6).
Investigations Radiology: X-rays for tendon calcications or bone deformation.
US high sensitivity and/or MRI to conrm diagnosis, asses rotator cuff tear and degeneration.
Treatment Acutely—if there is signicant tear refer the patient to orthopedic surgery.
In partial tear or tendinitis consider conservative therapy:
• Avoid aggravating activity.
• Apply ice over tendon for 15mins 4–6 times daily.
• NSAIDs. Local glucocorticoid inject with lidocaine may be considered.
• Physiotherapy: Range of motion stretching and strengthening exercises.
Subacute treatment—If no improvement is achieved within two to three months:
Glucocorticoids—subacromial glucocorticoid injection is a common treatment to controlling
the symptoms [20].

Anatomy It is the largest tendon in the body formed by the union of tendons of soleus and gastrogenemius
muscles to form Achilles tendon. It inserts posteriorly at the calcaneus
Muscles action Plantar exion
Epidemiology • patients are usually 30–40 years of age
• males are equally affected like females
• rupture Achilles tendon is ve times more common in males
Risk factors Excessive supination, increase intensity of training program and increasing time in training
(basketball and football players), repetitive stress, obesity, male gender, previous history,
mechanical factors: Pes planus and pes cavus deformities, over pronation of foot, and drugs—
Fluoroquinolone or local glucocorticoid use
Symptoms • pain with activity relieved after rest
• pain 2–6cm above insertion of the tendon, swelling, and possibly redness
• in rupture Achilles tendon patient feels struck violently in the back of ankle or hears loud
popping sound with severe pain
• absence of pain dose not rule out Achilles tendon rupture
Signs • gait and excessive foot supination. This is common with genu varaus deformity in the knee
• examine the patient in prone position with feet hanging off at the end of the bed
• inspect for bruising, swelling, and foot misalignment
• palpation: Hotness, thick tendon or defect, edema, hematoma, tenderness
2–6cm above calcaneus and compare it with the other side
palpate the tendon in while in dorsiexion of the ankle, plantar exion, and
Neutral position
• assess retrocalcaneal bursitis as one of the differential diagnosis for heel pain
• crepitus in chronic tendinitis
• assess for peripheral vascular disease (pulse, capillary rell, hair loss, and edema)
Notes:
The retrocalcaneal bursitis causes pain, fullness, or swelling proximal and anterior to the
insertion of Achilles tendon in to the calcaneus
The posterior tibial tendinitis causes pain in medial side of the ankle
Special tests calf squeeze or (Thompson test): Sensitivity of 96% and specicity of 93% [21] (see
Chap. 2)
Matles test: Sensitivity of 88% and specicity of 85%: [21]
The patient lies prone with knees exed to 90°. Observe whether the affected foot is
dorsiexed or neutral (both are abnormal) compared with the uninjured side, where the foot
should appear plantar-exed
Investigations Radiology: US and/or MRI to conrm diagnosis, monitor treatment response, and/or to assess
why the patient is not responding if another diagnosis is missing
Treatment Avoid aggravating activity, support Achilles tendon with bandage, apply ice, NSAIDs can be
used, avoid glucocorticoid at it is associated with high risk of tendon rupture [22]. Consider
corrections of mechanical defects by providing custom-made orthotics that provide arch support
Consider rehabilitation and occupational therapy programs with eccentric exercise for around 12
weeks. Air heel brace cast can be used in severe cases
Supercial heat and cold compressors
Deep heat by (US and iontophoresis)
Surgery can be considered in refractory cases after 3–6 months if no improvement all measures
Acute tendon rupture: Apply ice, analgesic, rest the ankle, and consider immobilization trial in
few degrees of plantarexion. Consider surgical referral for partial ruputure: there is still no
clear rule for surgical intervention

Physical
exam
• localize tenderness in lateral epicondyle
• pain on resisted wrist extension while elbow in exion
• pain in resisted supination and hand shaking
• pain in resisted middle nger extension
• Normal ROM of the elbow except in severe cases
• few degrees of extension might be affected
• examine radial nerve
• in compression neuropathy the pain diffuses distally to
epicondyle and is associated with muscle weakness
Localized tenderness in medial
epicondyle
Pain on resisted wrist exion
while elbow in extension
pain with resisted forearm
pronation
• examine ulnar nerve
Investigation It is a clinical diagnosis and investigations are usually not required
X-rays if indicated to look for osteophytes and calcication in epicondyle
Treatment Phase 1: Symptom less than 6 weeks
• rest the joint and use splint
• physiotherapy (eccentric exercise)
NSAID: There is limited evidence, oral NSAIDs helps to reduce pain and improve the function
in 6 weeks [27], and there is limited benet of topical NSAIDs in acute epicondylitis [29]
Phase 2: If symptoms do not improve for 6–12 weeks
• repeat 3 views X-ray to identify other possible causes
• continue eccentric exercise
local injection of corticosteroid. If no improvement, repeat in 2–4 weeks for total of 2
Doses. Use of local corticosteroid injection in lateral epicondylitis improves many patient
Symptoms in 6 weeks but does not prevent recurrences and long-term outcome worseness
[30, 31]
Phase 3: If symptoms do not improve after 12 weeks
• do US and/or MRI
Alternate treatment option might be considered as platelet-rich plasma injections, autologous blood
injections, prolotherapy, extracorporeal shock wave therapy, and percutaneous needle tenotomy [32]
• surgery if more than 6 months with failed conservative therapy including corticosteroid
injection
• 1. debridement +_ arthroscopic drain
• 2. open debridement
• 3. Pericutanous tenotomy

22.1.9 Fasciitis
A fascia is a layer of fibrous connective tissue
(collagen) below the skin that covers underly-
ing tissues (muscles, blood vessels, and
nerves). Fasciitis is the inflammation of the
fascia that causes fibrosis and loss of elastic-
ity. The most common types of fasciitis are

planter fasciitis, palmar fasciitis, and eosino-
philic fasciitis (these types can be secondary
to autoimmune rheumatological diseases and
malignancies).

Symptoms suggestive of SpA (see Chap. 1) [35]
Physical
examination
• local tenderness
• limited ankle dorsiexion
The examiner should dorsiex the patient toes with one hand, then pull the plantar
Fascia tight, and then palpate with thumb or index nger of other hand, the fascia
From heel particularly the medial aspect where the plantar fascia originates to the
Forefoot: Tenderness can be elicited
Investigations • HLA-B27 and CRP if SpA is suspected
X-rays: Lateral and axial lms to detect thickness, fat pad abnormality, heel spur
And to rule out other causes
• MRI in resistant cases [36]
• US: 80% sensitivity and 88, 5% specicity to detect fascia thickening and edema [37]
Treatment • 80% resolve spontaneously by 12 months
• decrease physical activity and consider stretching exercise
• arch support with custom made orthotics and avoid at shoes
• ice massage
• NSAIDs can be tried for 2–3 weeks
inject with local glucocorticoid and lidocaine in resistant cases
Mechanical defects should be corrected otherwise symptoms may recur
• botulinum toxin injection might be considered
for resistant cases refer to surgery for cast and possible splint extracorporeal shock wave
therapy
• if still no response fasciotomy can be considered as 5–10% of cases ultimately required it

To evaluate the current evidence for the efficacy of corticosteroid injection and non-electrotherapeutic physiotherapy compared with control for treating lateral epicondylitis. Systematic review. We searched five databases in September 2012 for randomised controlled studies with a minimum quality rating. Of the 640 studies retrieved, 11 were included, representing 1161 patients of both sexes and all ages. Corticosteroid injection and non-electrotherapeutic physiotherapy. Relative risk (RR) or standardised mean difference (SMD) for overall improvement, pain and grip strength at 4-12, 26 and 52 weeks of follow-up. Corticosteroid injection gave a short-term reduction in pain versus no intervention or non-steroidal anti-inflammatory drugs (SMD -1.43, 95% CI -1.64 to -1.23). At intermediate follow-up, we found an increase in pain (SMD 0.32, 95% CI 0.13 to 0.51), reduction in grip strength (SMD -0.48, 95% CI -0.73 to -0.24) and negative effect on the overall improvement effect (RR 0.66 (0.53 to 0.81)). For corticosteroid injection versus lidocaine injection, the evidence was conflicting. At long-term follow-up, there was no difference on overall improvement and grip strength, with conflicting evidence for pain. Manipulation and exercise versus no intervention showed beneficial effect at short-term follow-up (overall improvement RR 2.75, 95% CI 1.30 to 5.82), but no significant difference at intermediate or long-term follow-up. We found moderate evidence for short-term and long-term effects of eccentric exercise and stretching versus no intervention. For exercise versus no intervention and eccentric or concentric exercise and stretching versus stretching alone, we found moderate evidence of no short-term effect. Corticosteroid injections have a short-term beneficial effect on lateral epicondylitis, but a negative effect in the intermediate term. Evidence on the long-term effect is conflicting. Manipulation and exercise and exercise and stretching have a short-term effect, with the latter also having a long-term effect.

Context: Symptomatic scapulothoracic bursitis and crepitus are disorders of the scapulothoracic articulation that are often poorly understood. They can be a source of persistent pain and dysfunction in the active overhead throwing athlete. It is important to distinguish between scapulothoracic bursitis and scapulothoracic crepitus. Scapulothoracic bursitis refers to inflammation of the bursae secondary to trauma or overuse owing to sports activities or work. Scapulothoracic crepitus is defined by a grinding, popping, or thumping sound or sensation secondary to abnormal scapulothoracic motion. Evidence Acquisition: This article presents the causes, diagnosis, and management of these shoulder conditions in a manner that is relevant to clinicians, athletic trainers, and physical therapists, and it reviews relevant studies to determine the consensus on nonoperative treatment, as well as open and arthroscopic surgical treatment. Results: The causes of scapulothoracic bursitis and crepitus include direct or indirect trauma, overuse syndromes, glenohumeral joint dysfunction, osseous abnormalities, muscle atrophy or fibrosis, and idiopathic causes. Scapulothoracic bursitis and crepitus remain primarily clinical diagnoses; however, imaging studies or local injections may also be helpful. The initial treatment of scapulothoracic bursitis and scapulothoracic crepitus should be nonoperative. Surgical treatment options include partial scapulectomy or resection of the superomedial angle of the scapula, open bursal resection, and arthroscopic bursectomy. Despite the lack of agreement among orthopaedic surgeons concerning which procedure is best for treating symptomatic scapulothoracic bursitis and crepitus, most reports have demonstrated good to excellent outcomes in a significantly high percentage of patients. Conclusion: Clearly, the best initial approach to these conditions is a nonoperative treatment plan that combines scapular strengthening, postural reeducation, and core strength endurance. The addition of local modalities, nonsteroidal anti- inflammatory drugs, and localized injections may also be helpful. If an appropriate trial of nonoperative management proves unsuccessful, surgical correction can produce good results.
Article
Chronic Achilles tendinosis is a condition with an unknown aetiology and pathogenesis that is often, but not always, associated with pain during loading of the Achilles tendon. Histologically, there are no inflammatory cells, but increased amounts of interfibrillar glycosaminoglycans and changes in the collagen fibre structure and arrangement are seen. In situ microdialysis has confirmed the absence of inflammation. It is a condition that is most often seen among recreational male runners aged between 35 and 45 years, and it is most often considered to be associated with overuse. However, this condition is also seen in patients with a sedentary lifestyle. Chronic Achilles tendinosis is considered a troublesome injury to treat. Nonsurgical treatment most often includes a combination of rest, NSAIDs, correction of malalignments, and stretching and strengthening exercises, but there is sparse scientific evidence supporting the use of most proposed treatment regimens. It has been stated that, in general, nonsurgical treatment is not successful and surgical treatment is required in about 25% of patients. However, in a recent prospective study, treatment with heavy load eccentric calf muscle training showed very promising results and may possibly reduce the need for surgical treatment of tendinosis located in the midportion of the Achilles tendon. The short term results after surgical treatment are frequently very good, but in the few studies with long term follow-up there are signs of a possible deterioration with time. Calf muscle strength takes a long time to recover and, furthermore, a prolonged progressive calcaneal bone loss has been shown on the operated side up to 1 year after surgical treatment.

To the Editor.— The report by Rudikoff et al (235:1054, 1976) on ultrasound diagnosis of Baker cysts does not mention an important limitation of this technique. If a Baker cyst completely ruptures rather than dissects into the calf, it may not be detected by an ultrasound B scan.1 In this case, arthrography would still be necessary for an accurate diagnosis.

Mycobacterium kansasii is a common cause of pulmonary infection as a result of nontuberculous mycobacteria, but is less commonly described as a cause of an orthopedic infection. We present the first case of M. kansasii subacromial septic bursitis in an immunocompromised host. This case demonstrates the diagnostic and treatment challenges associated with orthopedic infections caused by M. kansasii.

Operative treatment for septic pre-patellar bursitis generally involves open debridement in addition to an extended course of intravenous antibiotics. Skin necrosis and wound breakdown are potential complications of this procedure in addition to scar sensitivity and a prolonged recovery. We report endoscopic bursectomy for the treatment of septic pre-patellar bursitis in eight patients over a 3-year period. All patients had microbiological confirmation of an infective process. The average age was 36 years (23-68 years). The average hospital stay was 6 days (4-9 days). No patient had a recurrence or complained of tenderness or hypoaesthesia around their wound. No patient experienced wound complications or skin necrosis. The average return to work time was 18 days (7-22 days). We conclude that endoscopic bursectomy is a safe and effective treatment for septic pre-patellar bursitis with a shortened hospital stay and a quicker return to work than conventional open debridement.

Achilles tendinitis is one of the most common of all sports injuries. There is no consensus on treatment. To assess the effectiveness of various treatment interventions for acute and chronic Achilles tendinitis in adults. The Cochrane Bone, Joint and Muscle Trauma Group specialised register (December 2000), Cochrane Controlled Trials Register (The Cochrane Library Issue 4, 2000), MEDLINE (1966 to December 2000), EMBASE (1980 to 2001 wk 04), CINAHL (1982 to December 2000), and reference lists of identified trials were searched. Randomised or quasi-randomised trials of treatment interventions for acute and chronic Achilles tendinitis in adults. Studies focusing on pathological tendinitis were excluded. Excluded were those trials that compared different dosages of the same drug or drugs within the same class of drugs, for example different non-steroidal anti-inflammatory drugs (NSAIDs). Three reviewers independently assessed trial quality, by use of a ten item check list, and extracted data. Requests were sent for separate data for Achilles tendinitis patients in studies within trials of mixed patient populations. Where possible, quantitative analysis and limited pooling of data were undertaken. Nine trials, involving 697 patients, met the inclusion criteria of the review. Methodological quality was adequate in most of the trials with regards to blinding but the assessment of outcome was incomplete and short-term.There was weak but not robust evidence from three trials of a modest benefit of NSAIDs for the alleviation of acute symptoms. There was some weak evidence of no difference compared with no treatment of low dose heparin, heel pads, topical laser therapy and peritendonous steroid injection, but this could not be fully evaluated from the reports of four trials. The results of an experimental preparation of a calf-derived deproteinized haemodialysate, Actovegin, were promising but the severity of patient symptoms was questionable in the single small trial testing this comparison. The results of a comparison of glycosaminoglycan sulfate with a NSAID were inconclusive. There is insufficient evidence from randomised controlled trials to determine which method of treatment is the most appropriate for the treatment of acute or chronic Achilles tendinitis. Further research is warranted.

To evaluate the potential of etanercept versus sulfasalazine to reduce active inflammatory lesions on whole-body MRI in active axial spondyloarthritis with a symptom duration of less than 5 years. Patients were randomly assigned to etanercept (n=40) or sulfasalazine (n=36) treatment over 48 weeks. All patients showed active inflammatory lesions (bone marrow oedema) on MRI in either the sacroiliac joints or the spine. MRI was performed at weeks 0, 24 and 48 and was scored for active inflammatory lesions in sacroiliac joints and the spine including posterior segments and peripheral enthesitis by two radiologists, blinded for treatment arm and MRI time point. In the etanercept group, the reduction of the sacroiliac joint score from 7.7 at baseline to 2.0 at week 48 was significantly (p=0.02) larger compared with the sulfasalazine group from 5.4 at baseline to 3.5 at week 48. A similar difference in the reduction of inflammation was found in the spine from 2.2 to 1.0 in the etanercept group versus from 1.4 to 1.3 in the sulfasalazine group between baseline and week 48, respectively (p=0.01). The number of enthesitic sites also improved significantly from 26 to 11 in the etanercept group versus 24 to 26 in the sulfasalazine group (p=0.04 for difference). 50% of patients reached clinical remission in the etanercept group versus 19% in the sulfasalazine group at week 48. In patients with early axial spondyloarthritis active inflammatory lesions detected by whole-body MRI improved significantly more in etanercept versus sulfasalazine-treated patients. This effect correlated with a good clinical response in the etanercept group.
