title: [Distal radius fracture. Fracture stabilization with biodegradable osteosynthesis pins (Biofix). Experimental studies and initial clinical experiences].
abstract: K-wire stabilization and casting of unstable or intraarticular fractures of the distal radius has proven to be an effective method of treatment since many years. However the need of implant removal after fracture healing is a disadvantage of this method. For this reason we investigated on the use of biodegradable implants in a fracture model of the distal radius. The biomechanical testing with Polydioxanon-(PDS)-pins (Ethipin) showed too small primary stability for the use in vivo. Osteosyntheses with three Polyglycolacid-(PGA)-rods Biofix compared with three K-wires 1.6 mm on the other hand showed 82% initial stability. From May to September 1988 typical distal radius fractures in 11 patients have been stabilized with Biofix-rods. The result of primary reduction could be obtained in all cases. These first experiences suggested, that stabilization of distal radius fractures with Biofix-rods might alternatively be performed instead of K-wire pinning.
