ObjectiveTo determine the outcome after a sliding osteotomy for deformity correction following malunion of volarly displaced distal radius fractures.DesignRetrospective review of a consecutive patient series.SettingA university-affiliated, tertiary-care center.Patients/InterventionTen patients with symptomatic distal radius malunion following a volarly displaced distal radial fracture (Smith's fracture) were treated with an oblique sliding osteotomy and plate fixation, through a volar approach, without using an iliac crest bone graft. Five men and five women with an average age of 41.9 years were followed for an average of 2.7 years postoperatively.Main Outcome MeasurementsRange of motion, grip strength, Fernandez wrist score, radiographic parameters.ResultsAt latest follow-up, wrist extension improved from an average of 37 degrees preoperatively to 70 degrees postoperatively (P = 0.002), wrist flexion improved from an average of 40 degrees to 65 degrees (P = 0.012), and supination improved from an average of 31 degrees to 68 degrees (P = 0.002). Postoperative radiographs revealed an average deformity correction of 10.6 degrees of volar tilt, 7.7 degrees of radial inclination, 5.8 mm of ulnar variance, and 10.4 mm of volar translation. Using the Fernandez point score (0-20) system, the average overall score improved from 10.5 preoperatively to 17.6 postoperatively (P = 0.0001). Functional outcome was rated as excellent or good in 9 of 10 patients and fair in 1 patient (who experienced residual problems due to persistent ulnar-sided pain). There were two reoperations (one hardware removal, one distal ulnar hemiresection).ConclusionsThis method reliably restores distal radial anatomy, decreases pain, and improves supination without requiring iliac crest bone grafting.
