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.
本报告涉及使用Biofix C棒对10例内踝骨折进行手术固定的技术及结果。它们是圆柱形的可生物降解棒。生物棒由自增强复合材料制成。它由聚乙交酯基质和聚乙交酯纤维组成。该材料术前的弯曲强度超过200兆帕,超过松质骨强度的20至30倍。该材料在水解条件下5至6周内失去机械强度,并在接下来的几个月内完全溶解。本文介绍了我们自行研制的用于植入生物棒的导向工具的经验。所有骨折均愈合,无明显并发症。从第8天起,允许在膝下石膏固定6周的情况下完全负重。
