Abstract
Conservative treatment of the ‘boxer’s fracture’ gives acceptable functional results but often leaves the patient with a residual deformity.
Using a prograde intramedullary K-wire, we treated 23 consecutive patients with a fractured neck of the fifth metacarpal. Volar angulation exceeded 40°. A 1.6-mm pre-bent K-wire was inserted via the base of the fifth metacarpal in each case. Time to regaining full function, time to union and final functional and radiological outcome were recorded.
All 23 patients went on to full clinical and radiological union within six weeks. In 18 patients, the reduction was anatomical with no residual angulation. In five the residual angulation ranged from 5° to 15°, with a mean of 8°. There was a transient sensory neuropraxia in two patients.
This minimally invasive technique is a simple, cost-effective and reliable method of treating a ‘boxer’s fracture’ and ensures a rapid return to full function with little or no residual deformity.
