ObjectiveTo observe the long-term result of fibula grafting for reconstruction of the distal radius after giant cell tumor excision.MethodsFrom March 1994 to November 2004, 31 cases of fibula grafting for reconstruction of the distal radius for giant cell tumors performed were analysed. There were 12 males and 19 females. The patients were from 19 to 48 years old, and the mean age was 31 years. Twenty-four patients had Campanacci grade 3 lesions, and 7 patients had Campanacci grade 2 lesions. There were 6 cases of vascularized fibular grafting and 25 cases of non-vascularized fibular grafting. All cases were evaluated by clinical and radiologic examinations; the movement of the wrist and the grip strength was measured; the MSTS score and Mayo Wrist scores were calculated.ResultsClinical follow-up time after reconstruction averaged 86.3 months, range from 41 to 169 months. The mean time for bone union at the host-graft junctions was 5.1 months range from 3 to 9 months in vascularized group and 10.3 months range from 7 to 15 months in non-vascularized group. One patient who had non-vascularized fibula grafting developed non-union at the host-graft junction, and one patient had local recurrence (3.2%). Five patients developed an wrist dislocation after surgery. The average movements of the wrist were: 67.3 +/- 9.4 degrees of extension, 31.2 +/- 5.1 degrees of flexion, 14.1 +/- 4.7 degrees of radial deviation, 19.4 +/- 3.9 degrees of ulnar deviation, 33.8 +/- 6.6 degrees of pronation, 15.3 +/- 4.0 degrees of supination. Average grip strength was 33.1 kg range from 15.5 to 52.1 kg. Compared with the contralateral side, there were accounted for 73%. MSTS score averaged 25.5 from 23 to 29, Mayo wrist score averaged 56 from 40 to 65.ConclusionsEn bloc resection of giant cell tumor of the distal radius followed by reconstruction with a fibula graft is proved to be an effective method and results in a good functional outcome at long term follow-up evaluation. The stability of wrist is achieved by reconstruction of the capsule.
