PURPOSE To analyse the results of treatment of unstable intra-articular distal radius fractures using the percutaneous K-wire reduction-fixation and external fixator. MATERIALS AND METHODS A retrospective follow-up study of 22 cases was carried out. With use of the system of AO classification 9 cases were in C1 and 7 in C2, and 6 in C3. The average duration of follow-up for all fractures was 35 months. We evaluated the radiologic results, the functional results according to clinical evaluation scoring system by Green and O'Brien and osteoarthritis grade according to arthritic grading system by Knirk and Jupiter. RESULTS Excellent and good results were rated in 17 cases (77%) of all cases. At last follow-up the mean loss of radial length, radial inclination and volar tilt were 1.4 mm, 1.0o, and 1.4o respectively. Also 7 patients had grade I, 1 patient grade II, and 1 patient grade III arthritis. CONCLUSION We think that percutaneous K-wire reduction-fixation and external fixation is useful treatment method for the unstable intra-articular distal radius fracture. But severely comminuted AO type C3 fractures would need additional treatments such as open reduction and bone graft to acquire and maintain the articular reduction for better results.

There has been many treatment modalities in the distal radius fracture. Although there is no doubt that external fixators have a role in the treatment of some highly displaced distal radius fractures, many unstable distal radius fractures may be treated adequately with far less complicated and intrusive percutaneous pinning technique. The purpose of this study was to evaluate indication and effectiveness of Rayhack's transulnar percutaneous pinning technique. Authors reviewed the unstable intra-articular fracture of the distal radius of 15 cases treated with Rayhack's transulnar percutaneous pinning technique between March 1994 and February 1997. At the final follow-up examination, the mean loss of radial length, radial inclination and volar tilt was respectively 0.4mm (3.9%), 2.0 (10.6%), 2.1 (14.7%). Posttraumatic arthritis was occurred in 1 case (11.1%) of less than 1mm residual articular step-off, 2 cases (40%) of more than 1mm and less than 3mm residual articular step-off, 1 case (100%) of more than 3mm residual articular step-off. Distal radioulnar joint synostosis by percutaneous pinning was not found. According to Demerit point rating system, excellent to good results were obtained in 73.3%. Authors suggest that Rayhack's pinning technique can be applied in terms of simple procedure, cost-effectiveness and functional outcome.
