To evaluate radiological and clinical results of the antegrade intramedullary prebent K-wire fixation for the 5th metacarpal neck fracture.

Between January, 2006 and December, 2009, 31 patients with displaced neck fracture of the fifth metacarpal who received antegrade intramedullary prebent K-wire fixation were included in this study. Radiological and clinical outcome evaluations were performed.

All the fractures were completely united. In the oblique radiographs, the average of preoperative angulation was corrected from 38.9° to 4.4°. The average difference between postoperative and final follow-up was 1.2°. Clinical outcomes were satisfactory except for one patient who had sustained ulnar nerve dorsal branch injury during surgery.

Antegrade intramedullary prebent K-wire fixation may be preferentially considered as one of the best ways to fix the displaced neck fractures of the fifth metacarpal.
