Treatment of displaced radial head fractures by internal fixation with absorbable pins.

ABSTRACT

OBJECTIVE: To study the effect of internal fixation with absorbable pins on treatment of displaced radial head fractures. METHODS: From May 1999 to May 2004, 16 patients with displaced radial head fractures (Mason types II and III) were treated with internal fixation by absorbable pins. The duration of follow-up averaged 22.6 months (12-58 months). The outcome was assessed on the basis of elbow motion, radiographic findings and the functional rating score delineated by Broberg and Morrey. RESULTS: All fractures healed within 10 months without avascular necrosis of radial head. The mean elbow flexion loss was 15 degrees (0 degrees-35 degrees), and pronation and supination decreased by 10 degrees (0 degrees-30 degrees) on average compared with those of the contralateral elbow. Five patients had an excellent result, 6 a good result, and 3 a fair result according to the criteria of Borberg and Morrey. CONCLUSIONS: Internal fixation with absorbable pins is an effective method in treating displaced radial head fractures. It can maintain the biomechanical stability of forearm, improve the elbow function and avoid second operation.
