Abstract
The purpose of this study was to develop a technique allowing a faster return to previous activities after surgical treatment of short transverse and oblique fractures of the diaphysis of the fifth metacarpal. It consisted of an anterograde and retrograde centromedullary double pinning connected. Our series included 40 patients of average age 25 years including 2 women. In 20 cases (group I), an anterograde centromedullary pinning with a 1.6- or 2-mm pin was performed followed by a 6-week orthosis and then 2-week self-education. In 20 cases (group II), an anterograde and retrograde centromedullary double pinning was performed using 2 1.5-mm pins connected by a connector (MétaHUS®, Arex™). A first pin was introduced into the canal antegrade, then the second retrograde. The 2 externalized pins were connected, and self-rehabilitation was encouraged. Mean tourniquet time was 14.75 min (group I) and 15.8 min (group II), respectively. At the last follow-up, the average pain was 0.35/10 and 0.2/10, the Quick DASH 0.68/100 and 0.57/100, the strength of the hand 94.65% and 94.35%, the active flexion MCP 98.5% and 99%, respectively. MCP active extension was 98.5% and 98.75%; the sick leave was 8.4 and 6.3 weeks. All fractures healed without recovery with 3 complications: 2 infections on pins, in each group, 1 CRPS1 (group I). Our results seem to show that the technique of anterograde and retrograde centromedullary double pinning connected in the treatment of short transverse and oblique fractures of the diaphysis of the fifth metacarpal gives results at least as good as the reference technique with a non-negligible socioeconomic advantage, a less time off work.
