Modified Split Ulnar Gutter Splint for Treatment of Fifth Metacarpal Neck Fractures

ABSTRACT

PURPOSE: To evaluate radiological results of the modified split ulnar gutter splint for the fifth metacarpal neck fracture. METHODS: Between December 2008 and May 2014, 17 patients (18 cases) with fifth metacarpal neck fractures were managed with our modified split ulnar gutter splint. Radiological outcomes in oblique and lateral radiographs were evaluated. Mean immobilization period was 4.9 weeks (range, 4-7) weeks. Mean follow-up period was 17.1 week (range, 8-80 weeks). RESULTS: All of 18 fractures were completely united. The average of prereduction dorsal angulation, 27degrees in the oblique radiographs and 21degrees in the lateral radiographs, were corrected to 17degrees in the oblique radiographs and 10degrees in the lateral radiographs after closed reduction. At the last follow-up, they were 14degrees and 11degrees respectively. The mean difference of angulation deformity between in postreduction and final follow-up radiograms were 3degrees in the oblique radiographs and 1degrees in the lateral radiographs, which was not significantly different. CONCLUSION: Immobilization using modified split ulnar gutter splint will be a reliable option for the fifth metacarpal neck fractures in selected patients, which will avoid the surgeries.
