OBJECTIVE: To evaluate the efficacy of AO mini-fragment implants and 1.25-mm Kirschner wires using fragment-specific fracture fixation and double-column plating for displaced or unstable distal radial fractures. DESIGN: prospective and consecutive. SETTING: level II trauma hospital. PARTICIPANTS: 28 people with 30 fractures and an average follow-up of 21.1 (range 12-41) months, treated with fragment-specific fracture fixation. OUTCOME MEASUREMENTS: anatomical assessment using anteroposterior and lateral radiographs, graded according to Sarmiento's modification of Lidstrom's scoring system. CLINICAL OUTCOME ASSESSMENT: DASH and Modified Gartland and Werley scores. RESULTS: There were 24 excellent and 6 good radiological results. Final mean grip strength was 83% of uninjured side, and mean wrist range of motion was 61 degrees dorsiflexion, 54 degrees palmar flexion, 85 degrees supination and 83 degrees pronation. Gartland and Werley's demerit point system revealed 13 (43%) excellent, 12 (40%) good, 5 (17%) fair and no poor results. The mean DASH score was 18, with a standard deviation of +/-18. CONCLUSION: This fixation method is a reliable and low-cost alternative with good clinical and anatomical results, particularly useful in open reduction and internal fixation of comminuted intra-articular distal radial fractures.
