    ABSTRACT: The short stem designs currently available are significantly different and can be differentiated into neck containing, partial containing and neck resection designs. In this article, the differences in the design features are presented. These include the differences in the technique of implantation, the significant differences in the reproducibility of the given anatomy of the patient and also concerning their osteologic competence.

    ABSTRACT: Humeral resurfacing arthroplasty represents an alternative option to hemiarthroplasty for treatment of cuff tear arthropathy (CTA), with the advantages as follows: suitability for relatively young and high-demand patients because of preservation of bone stock and no loss of length, less invasive surgery, shorter operation time, no risk of periprosthetic stem fractures, and revision surgery can be undertaken easily. In the current study, resurfacing arthroplasty in combination with latissimus dorsi tendon transfer for CTA was performed. Three hypotheses: first, humeral resurfacing arthroplasty in combination with latissimus dorsi tendon transfer would improve the overall functional outcome in patients with CTA. Second, this combination would improve humeral external rotation. Third, this combination would improve abduction and shoulder elevation. Study was conducted as an observational case series. Fourteen patients (nine ♀ and five ♂) having CTA were included. Follow-up was carried out at the end of the 28th month for all patients. Constant Score was used for follow-up evaluation. Dorso-axillary approach was used for latissimus dorsi tendon transfer and ventral deltopectoral approach for Copeland resurfacing. Tendons were fixed to the greater tuberosity with two anchors. The absolute Constant Score significantly improved from 34 preoperatively to 69 postoperatively, relative Constant Score from 42 to 91 %, elevation from 95° to 138°, abduction from 88° to 147°, and external rotation from 16° to 22° (not significant). Humeral resurfacing arthroplasty in combination with latissimus dorsi tendon transfer in patients having CTA with preserved subscapularis function has satisfactory short-term functional clinical outcome. LEVEL OF EVIDENCE: IV.

    ABSTRACT: Purpose: The purpose of the present study was to evaluate the MRI of the hip musculature as well as specific blood parameters on comparison of the Bauer approach with the minimally invasive ALMI approach. Material and Methods: We compared two patient groups after total hip replacement, which were operated either via the Bauer or the ALMI approach. All 47 patients had the same cementless hip design. All surgeries were performed by two experienced hip surgeons with experience of more than 1200 ALMI approaches. The patient groups did not differ concerning age, sex or side which was operated on. All MRI were performed in a standardised technique with a Philips Outlook Proview (0.23 Tesla). Patients were scanned preoperatively, within 2 weeks after surgery and at time of follow-up 14 months after surgery. The evaluation of the MRI findings was performed by two independent and blinded examiners. In order to document the muscle damage we documented myoglobin (the day before surgery, 6 hours postoperatively and at the first postop. day) und troponin (6 hours postoperatively). Results: Preoperatively the male patients showed a significantly larger diameter of the gluteus medius muscle. We also could demonstrate in many patients a fatty degeneration even before surgery. At time of follow-up there was no significant difference between the two patient populations concerning the fatty degeneration. There was also no significant difference concerning the muscle atrophy. Muscle oedema, that was present before surgery, however, was no longer present at the time of follow-up. Two patients even preoperatively showed a lesion of the gluteus medius tendon. The range of the postoperative myoglobin level was high (118-5411 µg/L), in the ALMI group the standard deviation was 1445 µg/L, in the Bauer group it was 738 µg/L. There was no significant difference between both groups. Similar findings were documented for the troponin levels. Conclusion and Clinical Relevance: Even before THR many patients show significant degeneration in the hip muscles. Muscle oedema that was present before surgery had disappeared at the time of follow-up. The fatty degeneration was still present at the time of follow-up. There was no difference concerning the muscle atrophy between the ALMI and the Bauer groups.

    ABSTRACT: Posterior calcaneal exostosis treatment modalities have given rise to many controversial opinions. After failure of the conservative treatment, surgical bursectomy and resection of the calcaneal exostosis are indicated by many authors. But clinical studies also show a high rate of unsatisfactory results with a relative high incidence of complications. The minimally invasive surgical technique by an endoscopic calcaneoplasty (ECP) could be an option to overcome some of these problems. Between 1999 und 2010 we operated 164 patients with an age range between 16 and 67 years, 81 males and 83 females. The radiological examination prior to surgery documented in all cases a posterior superior calcaneal exostosis that showed friction to the Achilles tendon. All patients included in the study had no clinical varus of the hind foot, nor cavus deformities. All patients had undergone a trial of conservative treatment for at least 6 months and did not show a positive response. The average follow-up was 46.3 (range: 8-120) months. According to the Ogilvie-Harris score 71 patients presented good and 84 patients excellent results, while 5 patients showed fair results, and 4 patients only poor results. All the post-operative radiographs showed sufficient resection of the calcaneal spur. In 61 patients the preoperative MRI showed a partial rupture of the Achilles tendon close to the insertion side. In no case could we observe a complete tear at the time of follow-up. Only minor postoperative complications were observed. In many patients we could observe a chondral layer at the posterior aspect of the calcaneus. Close to the intersion the Achilles tendon showed also in many patients a chondroide metaplasia. ECP is an effective and minimally invasive procedure for the treatment of patients with calcaneal exostosis. After a short learning curve the endoscopic exposure is superior to the open technique, has less morbidity, less operating time, and nearly no complications. Moreover, the pathology can be better differentiated.

    ABSTRACT: In over-head motion athletes a dysfunction of the suprascapular nerve has been described. In the literature a relation between the spinoglenoid ligament and the dysfunction of the suprascapular nerve is mentioned. An appreciable variability of this ligament is described. The purpose of the present study was the anatomic documentation of the spinoglenoid ligament and its relation to the suprascapular nerve. In 36 shoulder specimen the suprascapular nerve, the spinoglenoid and bony parameter of the scapula were documented. The statistic evaluation was performed with SPSS12.0. In all but one specimen a spinoglenoid ligament was present. In 20 cases (56 %) the infraspinatus muscle inserted at the spinoglenoid ligament. In five cases (14 %) the spinoglenoid ligament reached the glenohumeral joint capsule. In two cases the suprascapular nerve was completely fixed with the ligament, in four cases the perineural soft tissue had a close connection to the ligament. In four cases a branch of the nerve passed through the ligament. All together in 28 % of the specimen there were mechanical conflicts. In one case a ganglion compressed the nerve. Our anatomic study showed in a significant number of cases a possible entrapment of different origins. These findings have implications both for diagnostics and treatment.

    ABSTRACT: The purpose of the study was to analyse different parameters before and after implantation of a modern short-stem hip design. In this prospective radiological study 250 consecutive hips with degenerative hip osteoarthritis were included (246 patients). The patients were operated by five different surgeons at 4 different hospitals and a metadiaphysial fixed short-stem prothesis (Mini Hip, Corin) was used. Standardised X-rays were performed with the same technique pre- and postoperatively in all patients. Different anatomic parameters of the hip were documented by using the pre- and postoperative Xrays (ofset, CCD angle, length of leg). All measurements were performed by an independent examiner. The 246 patients included 129 females and 117 males. The average age of the patients was 59.7 years (range: 27-82 years). The offset only changed by + 0.28 cm (SD: 0.45 cm) after surgery. We could document only a small decrease of -0.51° (SD: 4.10°) of the CCD angle. The length of the leg increased on average by + 0.09 cm (SD: 0.34 cm). We found no difference between the measurements of female and male patients. Conspicuous was also the increasing use of small protheses (size 2) for hips with a small CCD angle and the increasing implantation of large protheses (size 9) in hips with a high CCD angle. Our results showed that we could reconstruct the individual geometry of the hip quite well by using the metadiaphysial short-stem prothesis. The tendency of an increasing CCD angle and a decrease of the offset seems not to be existent with the design of this kind of short-stem prothesis.

    ABSTRACT: Osteoarthritis (OA) is a degenerative joint disease that is characterized by increasing loss of cartilage, remodeling of the periarticular bone, and inflammation of the synovial membrane. Besides the common OA therapy with nonsteroidal anti-inflammatory drugs (NSAIDs), the treatment with chondroprotectives, such as glucosamine sulfate, chondroitin sulfate, hyaluronic acid, collagen hydrolysate, or nutrients, such as antioxidants and omega-3 fatty acids is a promising therapeutic approach. Numerous clinical studies have demonstrated that the targeted administration of selected micronutrients leads to a more effective reduction of OA symptoms, with less adverse events. Their chondroprotective action can be explained by a dual mechanism: (1) as basic components of cartilage and synovial fluid, they stimulate the anabolic process of the cartilage metabolism; (2) their anti-inflammatory action can delay many inflammation-induced catabolic processes in the cartilage. These two mechanisms are able to slow the progression of cartilage destruction and may help to regenerate the joint structure, leading to reduced pain and increased mobility of the affected joint.

    ABSTRACT: During the last decade there have been significant changes in the perioperative management of total hip replacement patients. This process begins in the preoperative phase. Many patients are much better informed and standardized preoperative patient programs improve patient outcome and optimize the clinical pathways. The techniques in perioperative pain management have also significantly improved. The surgeon should not only rely on the anesthesiologist but should also use the options available during surgery. Postoperative weight bearing is handled in a much more progressive way than previously. In a standard primary hip replacement pain-adapted full weight bearing is possible if there are no patient-specific problems. There has also been a shift in the postoperative capability of performing athletic or recreational activities. In general patients can perform those activities that were performed before the surgery, which also includes, for example downhill skiing.

    ABSTRACT: Objectives:The primary objective was to compare a single, 6 ml, intra-articular injection of hylan G-F 20 with placebo in patients with symptomatic knee osteoarthritis. The safety of a repeat injection of hylan G-F 20 was also assessed.Methods:Patients with primary osteoarthritis knee pain were randomly assigned to arthrocentesis plus a 6 ml intra-articular injection of either hylan G-F 20 or placebo in a prospective, double-blind (one injector/one blinded observer) study. Results were evaluated at 4, 8, 12, 18 and 26 weeks post-injection. The primary outcome criterion was change from baseline over 26 weeks in Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index A pain. Secondary outcome measures included WOMAC A1 and C, patient global assessment (PGA) and clinical observer global assessment (COGA) and Outcome Measures in Rheumatology, Osteoarthritis Research Society International responder rates. A 4-week, open, repeat treatment phase evaluated safety only.Results:A total of 253 patients (Kellgren–Lawrence grade II or III) was randomly assigned. Patients receiving hylan G-F 20 experienced statistically significantly greater improvements in WOMAC A pain scores (−0.15, SE 0.076, p = 0.047), and several of the secondary outcome measures (WOMAC A1, PGA and COGA), than patients receiving placebo. There was no difference between the safety results of the two groups. No increased risk of local adverse events was observed in the open, repeat treatment phase.Conclusions:This placebo-controlled study demonstrated that, in patients with knee osteoarthritis, a single 6 ml intra-articular injection of hylan G-F 20 is safe and effective in providing statistically significant, clinically relevant pain relief over 26 weeks, with a modest difference versus placebo.Trial registration number:NCT00131352.

    ABSTRACT: The purpose of this study was the evaluation of the ankle's anterolateral ligament structures. We documented the anatomic situation of the ankle's anterolateral ligament structures in 33 Thiel-embalmed specimens. The ligaments had been isolated. We performed measurements on both length and orientation and additionally classified the ligaments. We also conducted histologic tissue staining. We were able to document a regular appearance of a so far not well-realized structure between the talus and the tibia, present in 26 (79%) specimens. Average length of this structure was 26 mm (in 20 degrees plantarflexion). The angular orientation in relation to the ant. tibio-fibular lig. was on average 43.7 degrees. This structure could be classified as being either isolated or widespread, with a further four sub-classifications for the orientation. Histologic staining showed parallel orientated dense collagen fibers as well as elastic fibers and hyaline cartilage in different stages of proliferation. In addition, there were neural fibers in the perivascular and the soft tissue. The histologic findings proved that the structure was a ligament. Since the ant. tibio-talar lig. is constantly present in most ankle joints, it could be considered as a regular finding. Its morphology and histology show that this ligament is loaded under tension as well as under compression. This could be one reason for anterior ankle impingement.

    ABSTRACT: The purpose of this study was to evaluate the stop screw method inserted with a minimal invasive technique in the treatment of flexible flatfoot in children. We evaluated the results in a series of 21 flat feet in the age group ranging from 8 to 14 years between 1999 and 2007. The correction was evaluated clinically by assessment of heel valgus angle, range of motion of the ankle joint, and the photopodographic grading. The radiological assessment was performed by measuring the talonavicular angulation (Meary's line). At time of follow-up there was significant improvement in the heel valgus angle during rest and during tiptoe standing, significant improvement in the dorsiflexion from neutral position, and in podographic grading. Radiologically talonavicular angulation improved significantly from 162+/-8.9 degrees preoperatively to 174+/-5.8 degrees postoperatively. We can conclude that subtalar arthroereisis is relatively simple, effective, and minimally invasive procedure in treating flexible flatfoot in pediatric age.

    ABSTRACT: The purpose of the study was to evaluate the effect of suprascapular nerve block (SSNB) in shoulder surgery. The study group consisted of 260 patients, which were subjected to shoulder operations. The patients were divided into two equal groups: group I with nerve block compared to a control group II without a nerve block. The mean age of the patients in group I was 56.2 +/- 6.86 years and that in group II was 54.5 +/- 7.06 years. The female to male ratio was 71:59 in group I and was 69:61 in group II. Surgical procedures were arthroscopic rotator cuff repair, arthroscopic subacromial decompression, arthroscopic acromioclavicular resection, arthroscopic removal of calcific tendonitis, arthroscopic reconstruction of instability, arthroscopic capsular release and shoulder replacement. In all cases the pain was documented by the visual analogue scale (VAS) preoperative, at the first, the second as well as at the third day after surgery. In order to evaluate the amount of fluid, which is needed for infiltration of the area of the supraspinatus fossa, we injected different amount of local anesthetic in combination with contrast dye in five patients. In this study to document the fluid distribution, after injecting with different milliliters, 10 ml is proved to be more than enough to have sufficient local anesthetic to block the SSN. Pre-operatively the mean VAS was comparable between both groups. We documented a significant difference in favour of SSNB from day 1 to day 3 after surgery. No specific complications due to this nerve block procedure were found in any patient post-operatively.

    ABSTRACT: Viscosupplementation by repeated intra-articular injections of hyaluronic acid (HA) is used widely in the treatment of symptomatic knee osteoarthritis (OA). The number of injections required can limit the availability of treatment and affect patient compliance. The aim of this study was to assess different dosing regimens of hylan G-F 20, a high molecular-weight cross-linked derivative of HA, in the treatment of pain due to knee OA. Pilot, prospective, multi-centre, open-label, randomised trial in 100 patients with unilateral, symptomatic, tibio-femoral OA (Kellgren-Lawrence grade II or III), aged > or =40 years. Patients were randomised to receive varying dosing regimens of hylan G-F 20 (1 x 6 mL, 1 x 4 mL, 2 x 4 mL 2 weeks apart, 3 x 4 mL 1 week apart, or 3 x 2 mL 1 week apart). Adverse events (AE's) were monitored throughout the study. The primary efficacy endpoint was the change from baseline in the patient-rated knee OA pain assessment (100 mm visual analogue scale (VAS)) at 24 weeks. The secondary efficacy criteria included the WOMAC index, patient and physician global assessments using a 100 mm VAS, and knee OA pain assessment at all other visits. Concomitant use of permitted rescue medications (paracetamol) was also assessed. The treatment was well tolerated overall. Patients in the 3 x 4 mL group reported the highest percentage of device-related local AE's (30%) while patients in the 1 x 6 mL and 3 x 2 mL groups reported only 10%. There were no serious device-related AEs. There was a statistically significant improvement from baseline at week 24 in all efficacy endpoints for all treatment regimens. The 1 x 6 and 3 x 4 and 3 x 2 mL treatment groups showed the greatest mean improvements (-34.9, -32.6 and -36.7 mm respectively) in the patient-rated knee OA pain assessment VAS. This study suggests that a single 6 mL injection of hylan G-F 20 may be as efficacious, and as well tolerated, as 3 x 2 mL one week apart. A double-blind, controlled trial is needed to confirm these data.

    ABSTRACT: Different interspinous implants are used as minimal invasive intervention in the management of degenerative disorders of the lumbar spine. We present a case with foreign body reaction due to polyethylene's wear after a device for intervertebral assisted motion (DIAM) implantation. We conclude that the polyethylene interspinous devices can cause biological response, therefore; the surgeons and the companies should carefully watch their patients following application of such devices.

    ABSTRACT: Glenohumeral arthritis with a massive rotator cuff tear is a devastating condition that seriously compromises the comfort and function of the shoulder. Cuff tear arthropathy presents a unique surgical challenge and many arthroplasty options were used for its treatment. The purpose of this study was to evaluate the clinical and radiological results of Copeland cementless surface replacement arthroplasty (CSRA) applied in patients with cuff tear arthropathy and intact subscapularis function. The study was conducted on twenty-five shoulders in twenty-five patients with cuff tear arthropathy with the subscapularis tendon still intact. The patients were prospectively followed-up clinically and radiologically for a mean of 26 months (range: 15 - 38 months). There were 16 female and 9 male patients. The mean age was 69.04 years (range: 53 - 83 years). The mean operative time was 38 minutes (range: 28 - 56 minutes). The clinical assessment was performed with the Constant score. The Constant score significantly improved from a mean of 14.04 points preoperatively to 53.17 points postoperatively. Of the patients, 88 % considered the shoulder to be much better or better as a result of the operation. Radiologically, the humeral offset, the lateral glenohumeral offset (coracoid base to the greater tuberosity), height of centre of instant rotation and the acromiohumeral distance were significantly increased. No intra- or postoperative complications were encountered. Our early results with the use of Copeland surface replacement in selected cases with cuff tear arthropathy are encouraging. The patients showed significant clinical (pain and range of motion) and radiological improvements. Moreover, if the surface replacement were to fail for any reason, it can be revised to a reverse prosthesis type as there is no lack of bone stock.
