[more] BACKGROUND: The use of a mega-endoprosthesis has become the method of choice for reconstruction after bone tumors. In this study, we sought to determine the functional outcome and complications associated with mega-endoprosthesis. METHODS: A retrospective review of the charts of 16 patients who had undergone resection of bone tumors followed by reconstruction with mega-endoprosthesis between 2006 and 2011 was performed. Functional evaluation was based on the Musculoskeletal Tumor Society (MSTS) scoring system. Complications of the procedures were also analyzed. RESULTS: Eight men and eight women at an average age of 36.7 years were included in the study. The tumor involved lower limb in 14 patients and upper limb in 2 patients. The average MSTS functional score was 72.3 ± 15. Excellent results were achieved in six patients, good in five, moderate and fair in two each and poor in one. Complications occurred in eight patients. Two patients had aseptic loosening of the femoral component of total knee replacement. Flap necrosis occurred in two patients, both of whom required latissimus dorsi free flap for coverage of total knee prosthesis. One patient underwent revision of femoral component subsequent to knee dissociation. Local recurrence of tumor, patellar tendon rupture and foot drop occurred in one patient each. CONCLUSION: Mega-endoprosthetic reconstruction in limb salvage provides good functional outcome in patients with bone tumors.

[more] To identify variables affecting length of hospital stay after total hip replacement (THR) while controlling for potential confounders. Records of 199 consecutive elective unilateral THRs were reviewed. Clinical and demographic data including age, gender, body mass index, comorbidities, surgical factors (surgical approach, type of prosthesis, use of cement, operating time), anaesthetic factors (type of anaesthesia, ASA physical status), and length of hospital stay were recorded. 64% of patients left hospital within 12 days, 28% within 3 weeks, and 8% after 3 weeks. The median length of hospital stay was longer in women than men (11.5 vs. 9 days, p=0.009), in patients aged >65 years than those younger (13 vs. 9 days, p<0.0001), and in those with American Society of Anesthesiologists (ASA) grades 3 and 4 than grades 1 or 2 (14 vs. 9 days, p<0.0001). A greater proportion of women than men (45% vs. 27%, p=0.007), patients aged >65 years than those younger (61% vs. 37% or 24%, p<0.0001), and those with ASA grades 3 and 4 than grades 1 and 2 (68% vs. 25%, p<0.0001) stayed 12 days or longer. In the multiple regression analysis, the predictors for prolonged hospital stay (12 days or more) were patient age >65 years (p<0.003), female gender (p<0.05), and ASA grades 3 and 4 (p<0.0001). Of the 72 patients with prolonged stay, 7% had no, 26% had one, 42% had 2, and 25% had all 3 predictors. Prolonged hospital stay after THR is largely predetermined by case mix. Our study helps to identify individuals who need longer rehabilitation and more care.

[more] To review the clinical results of arthroscopic meniscal repair and to identify factors that may affect the outcome. A total of 15 arthroscopic meniscal repairs with inside-out in 14 patients over a 7-year period were evaluated retrospectively. The mean age was 41.2 +/- 11.5 years with a range of 26-64 years. Eleven patients underwent repair for medial meniscal tear, two patients for lateral meniscus and one patient for both in the same knee. All patients were functionally evaluated by Lysholm functional knee scores over an average follow-up of 1 year and 5 months (range: 0.5-7 years). The mean Lysholm score was 84 out of a maximum of 100. Functional outcome was excellent in 6 patients, good in 5, fair in 2 and poor in one patient. The patient with poor outcome was young with a chronic tear; she had concomitant ipsi-lateral radiculopathy and also had signs of reflex sympathetic dystrophy. One 64 year old patient with fair outcome developed a post-operative flexion contracture of 15 degrees. She also had moderate osteoarthritis of the medial compartment. One patient developed saphenous nerve neuralgia which was relieved spontaneously after a few months. All patients with excellent results were relatively younger with an acute tear. Elderly patients with concomitant osteoarthritis of the knee joint did not have a satisfactory outcome even if the tear was acute.

While the lungs and the central nervous system are most commonly infected, skeletal cryptococcosis is uncommon and isolated osteomyelitis due to Cryptococcus neoformans is quite rare. To our knowledge, only 47 cases of isolated cryptococcal osteomyelitis have been reported from 1974 to 2005. We report a case of isolated cryptococcal osteomyelitis in an immunocompetent patient, who received 12 weeks of fluconazole with complete recovery.

[more] Sarcoma encompasses an uncommon group of cancer and the data is insufficient from Pakistan. We report our four years experience of Sarcoma of soft tissues and bones. This cross sectional study was carried out at Aga Khan University Hospital from 2004 to 2008. The patients were divided into two groups from the outset i.e. initially diagnosed and relapsed group and separate sub group analysis was conducted. Out of 93 newly diagnosed patients, 58 belonged to bone sarcoma and 35 to soft tissue sarcoma group. While for relapsed patients, 5 had soft tissue sarcoma and 9 had bone sarcoma. Mean age was 32.5 years. At presentation, approximately two third patients had localised disease while remaining one third had metastatic disease. The Kaplan Meier estimate of median recurrence free survival was 25 months, 35 months, and 44 months for Osteogenic sarcoma, Ewing's sarcoma and Chondrosarcoma respectively. For Leiomyosarcoma and Synovial sarcoma, it was 20 and 19 months respectively. The grade of the tumour (p = 0.02) and surgical margin status (p = 0.001) were statistically significant for determination of relapse of disease. The median recurrence free survival of patients in our study was comparable to the reported literature but with significant lost to follow rate. Further large-scale, multi centre studies are needed to have a more comprehensive understanding of this heterogeneous disease in our population.

[more] Allogenic blood transfusion in elective orthopaedic surgery is best avoided owing to its associated risks. Total knee replacement often requires blood transfusion, more so when bilateral surgery is performed. Many strategies are currently being employed to reduce the amount of peri-operative allogenic transfusions. Anti-fibrinolytic compounds such as aminocaproic acid and tranexamic acid have been used systemically in perioperative settings with promising results. This study aimed to evaluate the effectiveness of tranexamic acid in reducing allogenic blood transfusion in total knee replacement surgery. This was a retrospective cohort study conducted on patients undergoing total knee replacement during the time period November 2005 to November 2008. Study population was 99 patients, of which 70 underwent unilateral and 29 bilateral knee replacement. Forty-seven patients with 62 (49.5%) knees (group-I) had received tranexamic acid (by surgeon preference) while the remaining fifty-two patients with 66 (51.5%) knees (group-II) had did not received any tranexamic acid either pre- or post-operatively. The mean drop in the post-operative haemoglobin concentration in Group-II for unilateral and bilateral cases was 1.79 gm/dl and 2.21 gm/dl, with a mean post-operative drainage of 1828 ml (unilateral) and 2695 ml (bilateral). In comparison, the mean drop in the post-op haemoglobin in Group-I was 1.49 gm/dl (unilateral) and 1.94 gm/dl (bilateral), with a mean drainage of 826 ml (unilateral) and 1288 ml (bilateral) (p-value < 0.001). Tranexamic acid is effective in reducing post-operative drainage and requirement of blood transfusion after knee replacement.

Standardised anteroposterior pelvic radiographs of 116 male and 20 female healthy volunteers aged 20 to 50 (mean, 33) years were taken. Morphologic dimensions of the proximal femur were measured, including canal flare index (CFI), morphological cortical index (MCI), femoral head offset, femoral head diameter, and femoral head position. Based on the CFI, 67% of the subjects had normal canal shapes (CFI, 3.0-4.7), whereas 1% and 33% of the subjects had stovepipe shapes (CFI, <3) and champagne-flute shapes (CFI, 4.7-6.5), respectively. Based on the MCI, 29% of the subjects had cylindrical shapes (MCI, <2.7) and 71% had trumpet shapes (MCI, >2.7). Morphology of the proximal femur in our study population differed significantly from those in western populations, indicating regional variation. It could also be due to the younger age of our population.

Developmental dysplasia of the hip.
Orthopedic reviews. 09/2010; 2(2):e19.
Developmental dysplasia of the hip (DDH) is a spectrum of anatomical abnormalities of the hip joint in which the femoral head has an abnormal relationship with the acetabulum.

[more] Developmental dysplasia of the hip (DDH) is a spectrum of anatomical abnormalities of the hip joint in which the femoral head has an abnormal relationship with the acetabulum. Most studies report an incidence of 1 to 34 cases per 1,000 live births and differences could be due to different diagnostic methods and timing of evaluation. Risk factors include first born status, female sex, positive family history, breech presentation and oligohydramnios. Clinical presentations of DDH depend on the age of the child. Newborns present with hip instability, infants have limited hip abduction on examination, and older children and adolescents present with limping, joint pain, and/or osteoarthritis. Repeated, careful examination of all infants from birth and throughout the first year of life until the child begins walking is important to prevent late cases. Provocative testing includes the Barlow and Ortolani maneuvers. Other signs, such as shorting of the femur with hips and knees flexed (Galeazzi sign), asymmetry of the thigh or gluteal folds, and discrepancy of leg lengths are potential clues. Treatment depends on age at presentation and outcomes are much better when the child is treated early, particularly during the first six months of life.

We aimed to determine the effect of physical activity on the healing of a muscle injury and to examine the pattern of innervation. Using a drop-ball technique, a contusion was produced in the gastrocnemius in 20 rats. In ten the limb was immobilised in a plaster cast and the remaining ten had mobilisation on a running wheel. The muscle and the corresponding dorsal-root ganglia were studied by histological and immunohistochemical methods. In the mobilisation group, there was a significant reduction in lymphocytes (p = 0.016), macrophages (p = 0.008) and myotubules (p = 0.008) between three and 21 days. The formation of myotubules and the density of nerve fibres was significantly higher (both p = 0.016) compared with those in the immobilisation group at three days, while the density of CGRP-positive fibres was significantly lower (p = 0.016) after 21 days. Mobilisation after contusional injury to the muscle resulted in early and increased formation of myotubules, early nerve regeneration and progressive reduction in inflammation, suggesting that it promoted a better healing response.

[more] To assess the lower-limb alignment and posterior tibial slope in Pakistanis. 40 male and 19 female healthy Pakistanis aged 20 to 45 years were recruited. A full weight-bearing anteroposterior radiograph of the entire lower limb of each subject was obtained. The axial alignment was measured based on the centres of the femoral head, knee, and ankle. The tibiofemoral (TF) angle, knee joint line obliquity angle (angle J), and posterior tibial slope were determined. The mean TF angle was more varus in men than women (178.4 degrees vs. 180.0 degrees, p<0.001). The mean angle J was more medially inclined in men than women (93.4 degrees vs. 91.4 degrees, p=0.007). The mean medial tibial slope was greater in women than men (16.0 degrees vs. 12.5 degrees, p<0.001). The posterior tibial slope was greater in women than men (14.1 degrees vs. 12.5 degrees, p=0.02), and was greater than the 5 degrees to 10 degrees commonly reported. Knee alignment and geometry vary in different population subsets. With regard to total knee arthroplasty, the more medially inclined angle J in Pakistani men suggests that an anteroposterior cut of the distal femur should be in increased external rotation, compared with Pakistani women. Whereas the greater posterior tibial slope in Pakistanis suggests that a proximal tibial cut with a greater posterior tibial slope may reduce the chance of tibial loosening and increase postoperative knee range of motion, especially when using posterior cruciate ligament-retaining designs.

The city does not have an emergency response system and only one of the three public sector hospitals has a trauma centre. We describe the pattern of injuries and management of two terror-related mass casualty incidents involving suicide bombers in a developing nation with limited resources. The first incident occurred in May 2002 with 36 casualties, of whom 13 (36%) died immediately and 11 (30.5%) died at the primary receiving hospitals. The second incident was targeted against the local population in May 2004. The blast resulted in 104 casualties, of which 14 (13.46%) died at the site. All patients had their initial assessment and treatment based on Advanced Trauma and Life Support principles and documented on a trauma form.

[more] We carried out a cross-sectional study to measure the association of the seven acetabular parameters with pelvic morphometry and prevalence of hip dysplasia in our population. Convenience sampling was carried out and 250 consecutive patients who came to AKUH for intravenous pyelogram and had no complaints in the region of the hip joint were enrolled in the study. Post-micturition standardized plain antero-posterior pelvic radiographs of 250 asymptomatic adults (500 hip joints) was studied. There were 136 males (54.4%) and 114 females (45.6%). Mean age of our study population was 38 years (15-78 years). The average center edge angle was 35.5±6.6° standard deviation (SD), acetabular angle was 37.76±4.37°, depth to width ratio was 0.31±4.6°, roof obliquity was 10.6±6.2°, extrusion index was 0.1±5.8, lateral subluxation 8.9±2.7 mm, and peak to edge distance 17±3.98 mm. There was significant influence (p<0.05) of age in all angles except depth to width ratio. A total of seven hip joints (1.4%) were dysplastic with CE angle <25° while four of the seven hips were severely dysplastic with CE angle <20°. In the dysplastic group there was significant correlation (p<0.05) of CE angle with acetabular angle, depth to width ratio, extrusion index and peak to edge distance. Prevalence of hip dysplasia was found to be very low in our population. These results are consistent with the findings of studies carried out in other Asian countries.

[more] Hip fracture has been increasing in frequency for several decades, and 70-90% of patients who sustain a hip fracture survive for at least one year. Many of these survivors fail to regain their prefracture functional status. No work in this regard has been done in the developing world. Elderly patients with acute intertrochanteric fracture and fracture of the femoral neck were followed up prospectively for 12 months after surgery to record the mortality, morbidity, functional status and complications. Three hundred and forty-five patients (61% female) were assessed at six and 12 months after surgery, which included 62.9% intertrochanteric fractures and 37% femoral neck fractures. The mechanism of injury was from a fall in 67% of the cases. Nineteen patients died within six months after surgery while another eight died during the next six months. Obesity, male gender, multiple comorbidities and below normal ambulation status before fracture were identified as major determinants of bad functional outcome.

Affecting the long term survivors of breast cancer, lymphangiosarcoma (Stewart-Traves Syndrome) has a high mortality rate. Since lympedema following radical mastectomy or axillary clearance and radiotherapy seems to be the main predisposing factor, further research regarding modifications in the surgical technique of axillary nodes dissection as well as the development of new chemotherapeutic agents effective in lymphangiosarcoma are required.

[more] Osteochondritis dissecans entails a hyaline cartilage defect of the articular surface causing pain and functional restriction in young adults, sometimes resulting in early degenerative arthritis. Conventional treatment methods such as abrasion chondroplasty and mosaicplasty have limitations in terms of quality of the resultant cartilage and donor site morbidity. A more recent technique, autologous chondrocyte implantation (ACI) results in hyaline cartilage formation and gives good long-term outcome, but requires a high-level cell culture facility and two surgical procedures. The patient was a young female with knee pain, intermittent locking and feeling of "joint mouse". MRI scan and arthroscopy showed a 2 x 2 cm full thickness osteochondral defect in the medial femoral condyle. A free fragment of articular cartilage was found, which was extracted arthroscopically, and chondrocytes were cultured from it in the Juma laboratory. Subsequently, patient underwent surgery whereby the chondrocytes were injected under a periosteal patch sewn over the defect. Over six months, patient's symptoms completely resolved and she returned to full function. A repeat arthroscopy after one year revealed complete filling of the previous defect with normal appearing cartilage indicating success of the procedure. This technology can be utilized for treating patients with a variety of conditions affecting hyaline cartilage of joints.

[more] OBJECTIVE: To evaluate the radiographic and functional results of the triple procedure (open reduction, femoral shortening and Salter's Osteotomy) in the treatment of Developmental Dysplasia of the Hip (DDH) disease in older children. METHODS: This case-series comprising 23 patients (29 hips) underwent the triple procedure of open reduction, femoral shortening and Salter osteotomy, at Aga Khan University Hospital between June 1995 and June 2005. Patients were classified pre-operatively according to the Tonnis class. Postoperative functional evaluation was performed using Modified MacKay's scoring system and radiographic assessment using Severin's scoring method. RESULTS: The mean age of patients at presentation was 6.84 years and the average follow-up was 19.6 months. The MacKay score was 'Good' to 'Excellent' in 25 hips; we had a failure in 1 hip joint. The Severin's class was I in 15 (51.7%) hips at the time of final evaluation as compared to none at the time of presentation. Patients younger than 5.6 years of age had a better radiological and clinical outcome as compared to older patients (p-value < 0.05). CONCLUSIONS: The triple procedure of open reduction, femoral shortening and Salter osteotomy gives best results in younger children. Early diagnosis and intervention is therefore imperative in the successful treatment of patients suffering from DDH.

[more] ABSTRACT: BACKGROUND: With increasing prevalence of gunshot injuries we are seeing more patients with retained bullet fragments lodged in their bodies. Embedded lead bullets are usually considered inert after their kinetic energy has dissipated hence these are not removed routinely. However, exposure of any foreign body to synovial fluid may lead to rapid degradation and hence result in systemic absorption, causing local and systemic symptoms. We present the case of a thirty year old man who came to our out patient department with a history of progressive, severe hip pain ten years after a gun shot injury to his right hip. CONCLUSION: The common belief that intraarticular bullets should not be removed has no benefit and may result in unwanted long term complications.

[more] ABSTRACT: We report the case of a young adult who presented with a painful foot due to chondroblastoma associated with an aneurismal bone cyst.Chondroblastoma is a rare benign cartilaginous neoplasm that accounts for approximately 1% of all bone tumors and characteristically arises in the epiphysis of a long bone, particularly the humerus, tibia, and femur. Chondroblastoma can affect people of all ages. It is, however, most common in children and young adults between the ages of 10 and 20 years. Association of chondroblastoma with aneurysmal bone cyst is well documented however this association has only once been reported in the cuboid.Imaging techniques should be supplemented with an open biopsy for the final diagnosis. Management with curettage, use of high speed burr and bone grafting has shown very good outcomes.
