Abstract
Limb preserving surgery following segmental resection of the distal end of the radius and its articular surface presents a major challenge. We have studied 11 consecutive patients with aggressive tumours located in the distal radius that required segmental resection of the distal radius and its articular surface to evaluate the clinical and functional outcome of reconstruction of such defects.
The mean age at the time of diagnosis was 33 years (7–60). Follow up ranged from 12 to 306 months (median 56). Histological diagnosis was osteosarcoma in 4 patients, chondrosarcoma in 2, giant cell tumour in 5 and meta-static carcinoma in 1 patient. Four patients received chemotherapy. The length of excised bone ranged from 6 to 14cm. Reconstruction was performed with non-vascularised proximal fibula strut graft in 6 patients, ulna transposition in 3 and custom made endoprosthesis in 2 patients. The wrist joint was arthrodesed in 5 patients.
At the time of review 2 patients had died of disease, one was alive with disease and 8 were alive and free of disease. Non-union of the graft occurred in one patient, reflex sympathetic dystrophy in 2 and prosthetic dislocation in one. One patient had local recurrence. Four patients required further surgery including one patient who needed an amputation for severe reflex sympathetic dystrophy, one graft revision for non-union, one secondary wrist arthrodesis and one closed reduction of dislocated endoprosthesis. Patients without arthrodesis often had clinical and radiological signs of wrist instability. The majority of the patients achieved satisfactory function with little or no discomfort and ability to perform activities of daily living.
We conclude that limb salvage surgery is worthwhile in patients with resectable tumours of the distal radius.
