Abstract
Purpose.
To evaluate outcomes of wide resection and reconstruction of the distal radius with non-vascularised autogenous fibular grafts for giant cell tumour (GCT) of bone.
Methods.
Medical records of 7 men and 5 women aged 22 to 47 (mean, 31) years who underwent wide resection of the distal radius and reconstruction with non-vascularised autogenous fibular grafts for GCT of bone were reviewed. The mean length of the resected radius was 9 (range, 7–11) cm. The ipsilateral proximal fibula with a small portion of attached ligament was harvested. The articular surface of the graft was fixed to the scapholunate articular surface by Kirschner wires, and the ligament of the fibular head was sutured to the carpal ligaments. The graft was fixed to the proximal radius with a small dynamic compression plate. Iliac cancellous bone graft was added. Pain, instability, and functional status were assessed. Wrist joint movements were measured using a goniometer. The grip strength was measured. The operated and contralateral sides were compared.
Results.
The mean follow-up was 24 (range, 20–27) months. All patients achieved radiological union after a mean of 16 (range, 14–20) weeks. The mean active range of movement in the operated wrists was 32° dorsiflexion, 38° palmar flexion, 15° radial deviations, 12° ulnar deviations, 50° supination, and 60° pronation. Compared with the contralateral wrists, the operated wrists regained 60% of the function, with satisfactory grip strength, and normal finger and thumb movements and hand sensation. No patient had recurrence after 2 years. Two patients had minor dorsal subluxation, which was resolved with a wrist brace. Three patients had superficial infection, which was resolved with intravenous antibiotics and dressings. Two patients had peroneal nerve palsy, which recovered completely in 12 weeks.
Conclusion.
Non-vascularised fibular grafts for reconstruction of the distal radius after resection of a GCT of bone achieved good cosmetic and functional outcomes.
