Methods:Ten patients with giant cell tumor of distal radius of surgical treated in our hospital from January 2013 to January 2016 were enrolled in this study. All patients were grade Ⅲ,aged from 23 to 35 years,mean age (29. 2 ± 4. 1)years old,4 cases on the left and 6 cases on the right,8 cases of primary giant cell tumor of bone and 2 cases of recurrence. The average follow-up time was (39. 1 ± 10. 1)months. Patient's sur-gery related indicators,wrist function,imaging findings were analyzed. Results:The average MSTS score was 26. 2 ± 1. 8 (range:23～29)and DASH average score was 11. 0 ± 3. 1(range:6. 4 ～15. 4). The average degree of radial flexion was (12. 8 ± 2. 5)°(range:10°～17°),the average number of ulnar flexion was (14. 7 ± 4. 0)°(range:10°～21°)and mean flexion was (24. 8 ± 4. 7)°(range:15° ～31°),average degree of extension (35. 1 ± 3. 8)° (range:29°～42°),average degree of pronation (46. 9 ± 10. 8)°(range:26°～63°). The average degree of external rotation angle (38. 7 ± 6. 2)°(range:33°～53°). Forearm pronation is (44. 3 ± 6. 4)°,after rotation (46. 3 ± 7. 1)°, after operation (6. 8 ± 3. 5)months,the space between the ulnar and fibular joint was (2. 6 ± 1. 6)mm,the fibula ul-nar deviation angle was (28. 8 ± 4. 2)°,the fibula point was high (9. 4 ± 2. 5)mm,the ulna variable was (-1. 2 ± 1. 9)mm,and the lateral piers were (4. 9 ± 5)°. The average grip strength percentage was (63. 5 ± 9. 1)%(range:53% ～81%). Excellent rate of wrist function was 80. 0%. All patients showed varying degrees of degenerative arthri-tis manifestations of X-ray,including 5 patients in grade 1,4 patients in grade 2,1 patient in grade 3. Ten patients also observed varying degrees of bone resorption. A case of wrist subluxation. Conclusion:Tumor resection combined with non-vascular fibular grafting can be the most common method for the treatment of giant cell tumor of distal radi-us in the wrist. It is clinically promoted.
