AIM: The aim of this study was to describe and evaluate a surgical technique for the treatment of mallet finger fractures using a K-wire stabilization of the distal interphalangeal (DIP) joint and another K-wire pressing the bone fragment.
METHODS: Between June 2007 and March 2014, 41 patients (28 men, 13 women) with isolated closed mallet finger fracture were treated using two K-wires. In the cohort, the mean joint surface involvement was 44.3% (range: 28-62%). With a mean period of 23.6 months, patient follow-up lasted 13-34 months. The fingers were evaluated for loss of extension and flexion of the (DIP) joints. The results were graded using Crawford's criteria.
RESULTS: Union of all fractures took place at an average of 5.5 weeks after the surgical procedure. Average extension lag was 4°, and active flexion 71°. According to the Crawford rating scale, 35 fingers were excellent, four were good, one was fair, and one was poor.
CONCLUSIONS: Pressing fixation of the bone fragment with the end of a K-wire was a useful technique in the treatment of mallet finger fractures.
TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
