AbstractSurgical treatment for metacarpal neck fractures may be indicated for malrotation, palmar angulation exceeding 30° or metacarpal shortening exceeding 3 mm, although these thresholds have not been firmly established. In a retrospective study, we compared the clinical and radiographic results of 54 patients with displaced fifth metacarpal neck fractures who were treated with either medial locking plates (14 patients) or retrograde intramedullary K-wires (40 patients). At a mean follow-up of 26 months (range 12 to 62), metacarpal shortening and angulation were 2 mm greater and 4° greater, respectively, in the K-wire group. The plate group had an earlier return to work and greater aesthetic satisfaction, but operative time and complication incidence were higher. Range of motion, time to union, grip strength and Quick Disability of the Arm, Shoulder and Hand scores were similar. We conclude that medial plating offers no clear advantage over K-wire fixation in treating metacarpal neck fractures. Level of evidence: III.
