    Abstract:
    OBJECTIVES: To compare closed reduction and casting with closed reduction and external fixation with optional K-wire fixation for distal radius fractures with metaphyseal displacement but without joint incongruity. DESIGN: Prospective study. SETTING: Multicenter study at 3 University teaching hospitals. PATIENTS/PARTICIPANTS: A total of 113 skeletally mature patients with distal radius fractures with metaphyseal displacement, but without joint incongruity, were randomized to receive 1 of 2 standardized treatment protocols. Patients were evaluated at 6 weeks, 6 months, 1 year, and 2 years. INTERVENTION: Closed reduction and casting (n = 59) or closed reduction and external fixation (n = 54). MAIN OUTCOME MEASUREMENTS: Upper extremity function was measured using upper extremity MFA domain scores, overall Jebsen Taylor scores, and pinch and grip strength tests. Global function and pain were measured using the SF-36. Radiographic evaluation and range of motion were documented. RESULTS: Upper extremity MFA scores, Jebsen Taylor scores, SF-36 bodily pain scores, and grip strength improved significantly during the first year for all patients. By 2 years, mean Jebsen Taylor scores and SF 36 bodily pain scores for patients in both groups were similar to scores for normal age- and gender-matched population controls. At all points, there was a trend for better function in the external fixation; however, this did not reach statistical significance. There was a trend for better length and palmar tilt restoration with external fixation. CONCLUSIONS: For distal radius fractures with metaphyseal displacement but with a congruous joint, there exists a trend for better functional, clinical, and radiographic outcomes when treated by immediate external fixation and optional K-wire fixation.
