We analysed the results of 24 cases of aggressive benign and malignant tumours of the distal radius treated by resection and prosthetic replacement between 1995 and 2006. Patient ages ranged from 18 to 74 years, averaging 33 years; 18 were males. Recurrent giant cell tumour was the most common tumour. The prosthesis used was a bipolar hinge custom mega prosthesis manufactured locally. Average follow-up was 78 months. The average Musculoskeletal Tumor Society (MSTS) functional score achieved was 75%. The ten-year prosthesis survival was rate 87.5%. Infection was the most common complication.

Purpose We analysed 11 patients with malignant musculoskeletal tumours of the humerus who underwent limb salvage surgery with total humeral custom endoprosthesis from 1990 to 2009. Methods There were six male and five female patients, with a mean age of 17 years. The most common diagnosis was osteosarcoma. The average follow-up period was 66 months, with the maximum being 180 months. Functional and oncological outcomes were analysed. Results The one and five year cumulative survival (Kaplan-Meier method) rates were 90.9% and 77.9 %. The average Musculoskeletal Tumour Society Score (MSTS) was 80%. Two patients died due to metastasis. One patient had a forequarter amputation for local recurrence. The procedure provides fast recovery and relatively good restoration of elbow function, whereas active shoulder movements remain limited Conclusion Total humeral custom endoprosthetic replacement represents a viable treatment option in indicated patients, providing reliable and reasonable function of the upper limb, with a low complication rate.

Background:Despite advances in adjuvant therapy, Ewing’s sarcoma of the pelvis remains an anatomic site with a poor prognosis due to its relative inaccessibility, complex anatomy, and limited reconstructive options available. This study evaluates the role of surgery in the management of patients with pelvic Ewing’s sarcoma who also have received conventional radiation therapy and chemotherapy.Materials and Methods:From July 1990 to July 2006, we received 10 patients with Ewing’s sarcoma of pelvis at our center. Nine patients were in stage II B and one in Stage III at the time of presentation to us. All patients underwent surgical resection after preoperative chemotherapy with or without radiotherapy, which was given at the discretion of the referral center. Reconstruction was attempted using plate osteosynthesis in four patients, SS wires and screws in three patients, free fibular strut graft in one patient, and none was done in two patients.Results:Functional outcome assessed by Enneking’s criteria revealed excellent outcome in two patients, good outcome in five patients, and poor outcome in two patients. At a mean followup of 10.3 years, seven patients remained free from the disease, and three patients died. The 5- and 10-year cumulative survival (Kaplan Meier method) was 63% and 34%, respectively.Conclusion:This study demonstrates that surgery plus chemotherapy and radiation therapy is helpful for treating patients with pelvic Ewing’s sarcoma, particularly in achieving local control.

Background: Transverse acetabular ligament (TAL) is a 3-dimensional structure which cannot be defined by a single plane. Therefore, we aimed at describing the orientation of different parts of TAL with respect to anterior pelvic plane (APP) and correlate it with gender, body mass index (BMI), and Lewinnek's safe zone. Methods: A total of 109 consecutive patients undergoing imageless navigated THA were prospectively studied. Computer navigation was used as the measurement tool. APP was registered for navigation. After excision of osteophytes, a trial component matching the size of unreamed acetabular cavity was aligned with acetabular rim, outer and inner margins, and middle of TAL to record cup orientation with computer tracker. Results: Ninety-nine patients (41 males and 58 females, mean BMI of 28.8kg/m 2 ) were studied after applying exclusion criteria. Mean acetabular inclination was 55.15 , 53.00 , 47.70 , and 42.60 respectively, for acetabular rim, outer, middle, and inner margins of the TAL. Corresponding mean acetabular anteversion was 6.63 , 7.41 , 11.23 and 14.90 respectively. Overall, 17.17%, 28.28%, 47.47% and 71.71% of cup orientation corresponding to acetabular rim, outer, middle, and inner margin of TAL respectively, were within Lewinnek's safe zone. No association was established between BMI and acetabular orientation. Males had overall lesser anteversion than females. Conclusion: We describe orientation of outer, middle, and inner margins of TAL, as reference planes for TAL, in relation to APP. The anteversion differs significantly with gender. A knowledge about these will assist surgeon in component placement during THA, with inner margin of TAL providing the best chance of orientation out of the studied landmarks.
