Objective To observe the effectiveness of wrist joint reconstruction with vascularized fibular head graft after resection of distal radius giant cell tumor. Methods Between March 2000 and March 2009, 31 cases of distal radius giant cell tumor were treated with extended resection and vascularized fibular head graft for repairing defects of the distal radius, and reconstructing wrist joint. There were 14 males and 17 females with an average age of 37.2 years (range, 15-42 years). The disease duration ranged from 1 month to 2 years and 3 months with an average of 8 months. The size of
tumor was 6.5 cm 3.5 cm-8.0 cm 4.5 cm. The range of motion (ROM) of wrist joint was as follows: extension 5-15° (mean, 10.7°), flexion 9-21° (mean, 14.2 ), radial incl ination 0-10 (mean, 8.6 ), and ulnar incl ination 0-15° (mean, 7.9°). The ROM of forearm was as follows: pronation 15-50 (mean, 28.7 ) and supination 10-25° (mean, 16.5°). The histopathological examination revealed that there were 5 cases of stage I, 17 of stage II, and 9 of stage III. Results All patients achieved primary heal ing of incision and were followed up 1-9 years with an average of 4.5 years. The X-ray films showed that bone heal ing time was 12-16 weeks with an average of 13 weeks. No tumors recurrence was observed. The ROM of wrist joint was as follows at 1 year after operation: extension 20-50 (mean, 29.0 ), flexion 30-50° (mean, 35.0°), radial incl ination 10-20° (mean, 16.5°), and ulnar incl ination 20-25 (mean, 23.5 ). The ROM of forearm was as follows: pronation 40-90° (mean, 68.3°) and supination 30-80 (mean, 59.6 ). There were significant differences in the ROM between before operation and after operation (P  lt; 0.05). According to the Krimmer et al wrist score, the results were excellent in 17 cases, good in 12, and fair in 2. Conclusion Wrist joint reconstruction with vascularized fibular head graft can restore function of wrist joint. The operation is proved to be safe and effective in treating distal radius giant cell tumor.
