To prove that use of intramedullary cannulated headless hardware fixation of metacarpal fractures provides anatomic reduction, stable fixation, less operative trauma and early, active post-operative mobilization. The study compares two types of implant to determine efficacy in reduction and maintenance of reduction for fracture healing.
