Reconstruction of distal radius by fibula following excision of grade III giant cell tumour: follow-up of 18 cases.

The purpose of this study was to evaluate the long-term results of vascularised fibular graft for reconstruction of the wrist after excision of grade III giant cell tumour in the distal radius. From January 1998 to September 2003, 18 patients with wrist defects due to distal radius grade III giant cell tumour resection were treated with vascularised fibular graft and were followed-up. The limb function was restored to an average 80% of normal function and bone union was achieved within six months in 18 patients with vascularised fibular graft. MSTS score averaged 25.6 and ranged between 21 and 29; Mayo wrist score averaged 56 with a range from 40 to 65. It is appropriate to use the head of the fibula as a substitute for the distal radius. The healing of vascularised fibular graft is very quick and without bone resorption. Thus, in the procedure for reconstruction and limb salvage after bone tumour resection of distal radius, the free vascularised fibular graft with fibular head is an ideal substitute.
