Totally Bioresorbable Composites Systems for Internal Fixation of Bone Fractures

Metals have been used extensively for internal fixation of bone fractures. However, shortcomings of metallic plating or nailing are now well identified and the interest for internal fixation devices made of more flexible materials is growing fast. In this respect, plastic-based systems appear attractive, particularly carbon fiber reinforced composites. However, the most suitable solution remains the use of bioresorbable plastic systems due to their combining various potential advantages: — better bone remodeling because of better matching of mechanical properties with respect to bone, — no need for reoperation to remove the appliance after bone-healing, and — possibility for incorporating antibiotics in view of preventing infection through sustained delivery of the entrapped drug.
