Comparison between percutaneous transverse fixation and intramedullary K-wires in treating closed fractures of the metacarpal neck of the little finger.

We performed a non-randomized controlled clinical trial of 59 clinical cases to compare percutaneous transverse K-wire fixation and intramedullary K-wires in treating closed fractures of the metacarpal neck of the little finger. Twenty-nine patients were treated by percutaneous transverse K-wire fixation and 30 patients were treated with intramedullary K-wires. They were reviewed at a mean follow-up of 24 months for radiological and functional outcome in terms of union rate, union time, complication rate, pain, movement and grip strength. Radiographs did not show any significant differences in the union rate and union time. There was no statistical difference in complication rate, pain scores, total active motion and grip strength between the two groups. The authors suggest that both methods are comparable, good and safe methods of treating closed, displaced fractures of the metacarpal neck of the little finger, without significant complications.
