Simplified internal fixation of fifth metacarpal neck fractures - 31/03/18
Abstract |
Background |
Fifth metacarpal neck fractures (boxer's fractures) are common injuries that contribute 20% of all hand fractures. Divergent percutaneous pinning (bouquet fixation) as described by Foucher has gained popularity but is challenging and at times arduous, as it requires the insertion of several slender K-wires into a narrow medullary canal. Here, we report on a simplified technique in which a single thick K-wire is inserted.
Technique |
An 18/10 K-wire is bent at one end then mounted on a drill chuck. The incision is performed and the entry hole created using the K-wire, which is then advanced along the medullary canal. After reduction of the metacarpal head using the Jahss manoeuvre, the K-wire is inserted across the fracture site into the subchondral bone. Any persistent rotational malalignment is corrected by rotating the metacarpal around the K-wire. Immobilisation is by buddy taping covered by a resin guard.
Methods |
We collected follow-up data for 30 patients treated using our technique, at a mean age of 32 years.
Results |
90 days after surgery, the fracture was healed in all patients. No patients had rotational malalignment. Mean operative time was 14minutes. No complications were recorded.
Discussion |
The use of a single thick K-wire proved simple, effective, reproducible, and rapid. No rotational malalignment occurred. This technique is faster and easier to perform than divergent pinning with multiple K-wires.
Conclusion |
This technique can be used to treat fifth metacarpal neck fractures.
