Abstract

Purpose
To compare clinical and radiological results between percutaneous K-wire fixation, external fixator and external fixator with K-wire fixation for displaced comminuted intra-articular fractures in distal radius. Materials and Methods: Fifty-four patients who had a fixative surgery after closed reduction within acceptable range and could be followed at least 6 months were reviewed. Among them, twenty patients were fixed by K-wire and fourteen patients were fixed by dynamic external fixator. Another twenty patients were fixed by both K-wire and dynamic external fixator. These three groups were compared by range of motion of wrist and scoring system which was made by Hove et al. Radiologic evaluations consist of radial inclination, radial length, step-off and volar tilt were compared. Results: Dynamic external fixator with K-wire showed statistically significant better range of motion in dorsiflexion, volar flexion and pronation. And also lesser functional scorings, more radial inclination, more radial height and lesser step-off than other two groups. But there was no significant difference in radial deviation, ulnar deviation, supination and volar tilt and also no difference in the results was observed between K-wire and external fixator. Discussion and Conclusion: Our retrospective analysis demonstrated that external fixator with K-wire was the most effective operative treatment in displaced comminuted intra-articular fractures of distal radius.
