Purpose: To evaluate the amount and related factors of reduction loss in distal radius fracture after treatment by Kapandji technique. Materials and Methods: From September 2004 to May 2006, 44 cases (43 patients) of distal radius fractures were treated by Kapandji technique. Fracture were classified with AO classification and volar tilt, radial inclination, and radial length were measured in preoperative, immediate, postoperative radiographs. Also the amount and related risk factors of reduction loss were analyzed. In addition, the radiological results at last follow up were evaluated using modified Lidstrom scoring system. Results: There was significantly more reduction loss of volar tilt in the patients with AO type C comparing with other fracture types, but the patients who were treated using three k-wire fixations including intrafocal K-wires showed significantly more reduction loss of volar tilt also. Overall radiological results at last follow up showed that excellent was 50% in cases with dorsal comminution, but, the other cases 90%. In addition, excellent was 70% in type A cases, but, in type C 44%. Conclusion: Kapandji technique percutaneous pinning is the one of effective treatment options for distal radius fracture. But, type of fracture, total number of K-wires, and presence of dorsal cortical comminution showed the significant relation with postoperative reduction loss of volar tilt and overall radiological results at last follow up.
