Background: Optimization of the corrective osteotomy for the treatment of distal radius extra-articular malunion is an ongoing project.
Objectives: In this study, we aimed to evaluate the outcome of corrective osteotomy with K-wire fixation in the treatment of patients with symptomatic distal radius extra-articular malunion.
Patients & Methods: Twenty-three patients with symptomatic distal radius extra-articular malunion, mean age of 38.3±7.6 years, and a mean follow-up of 34.4±11.3 months were included. Corrective osteotomy was performed through a dorsal approach and using K-wire instead of the plate for the fixation of the osteotomy site. The outcome was assessed with radiographic measures including ulnar variance, radial tilt, radial inclination angle, radial height, and clinical measures including wrist range of motion, the short form of Disabilities of the Arm, Shoulder, and Hand (Quick-DASH), and the Modified Mayo Wrist Score (MMWS).
Results: Radiographic measures and wrist range of motion in all directions were significantly improved at the last follow-up. The mean final Quick-DASH score of the patients was 16.3±8. The mean final MMWS was 92.2±13.5. According to the MMWS, 9 (39.1%) patients had an excellent function, 13 (56.5%) patients had a good function, and one (4.4%) patient had a fair function. Radiographic union was observed in all wrists within an average period of 10.2±4 weeks. No postoperative complication was recorded.
Conclusion: Since K-wire fixation is less expensive, requires smaller incision, and provides acceptable radiologic and clinical outcomes, it could be regarded as a good alternative for plate fixation in corrective osteotomy for distal radius extra-articular malunion.
