BACKGROUND: Surgical management of osteosarcoma of the limb in childhood often involves extensive surgery. Intervention ranges from local resection to amputation depending on the level and the extent of the disease process. However, where the disease is extensive the level of amputation may preclude effective prosthetic use. In these circumstances resection of the diseased segment of the limb, i.e. an intercalary amputation and reconstruction with rotation of the tibial component of the limb can provide function equivalent to a below-knee amputee. METHODS: To examine the role of rotationplasty of the lower limb for childhood osteosarcoma of the femur, a retrospective study was carried out which examined the function of five patients who had been treated by a tibial rotationplasty. The records of two patients who had died from metastatic disease 2 and 4 years after surgery were examined. The three surviving patients were examined clinically and their clinical records and radiographs were reviewed. RESULTS: Of the two patients who died from metastatic disease, neither had local recurrence of the tumour, neurovascular complications, late derotations or psychological problems. In the three patients who survived, there had been no local recurrence of tumour or other complication and each has an excellent level of activity with below-knee function using a rotationplasty prosthesis. CONCLUSIONS: For children with osteosarcoma of the femur and with extensive disease that precludes complete limb preservation, resection and tibial rotationplasty provides function far superior to a high above-knee amputation or a hip disarticulation without the risk of local recurrence.
The use of western components and materials for prostheses is prohibitively expensive in most developing countries. In addition, local customs and conditions vary considerably from those for which the prostheses were designed. For these reasons, a trans-femoral prosthesis has been developed in Pokhara, Nepal, using entirely locally available materials, and with a view to fulfilling local requirements as far as possible. This paper describes the materials and fabrication technique for the component parts of the prosthesis, the local conditions for which it was developed, and a three year follow-up of the first prosthesis issued. Only one serious design fault was discovered during this period, and a modification to the fabrication procedure introduced. The authors believe that if this trend continues, this style of prosthesis may be useful in the future for Nepali amputees and perhaps also in other countries, particularly where mass production of components is not practical.
