[Use of Biofix C for stabilizing medial ankle fractures]

This report deals with the surgical technique and the results of stabilisation of 10 medial ankle fractures using Biofix C rods. They are cylindrical, biodegredable rods. Biorod is constructed of self-reinforced composite material. It consists of polyglycolide matrix with polyglcolide fibers. The bending strength of the material before operation is more than 200 MPa, exceeding 20-30 times the strength of cancellous bone. The material looses its mechanical strength in hydrolitic conditions during 5-6 weeks and dissolves totally during the following months. Our experience with a self developed guiding tool for the implantation of the Biorod is presented. All fractures healed without any notable complications. As of the 8th day full weight bearing was allowed in a below knee plaster cast for 6 weeks.
