Strecksehnenrupturen nach winkelstabiler palmarer Plattenosteosynthese distaler Radiusfrakturen

Abstract

. Abstract The internal fixation of fractures of the distal radius can lead to complications related to the implants although there have been few reports in the literature. Extensor tendon ruptures secondary to the volar plate ostheosynthesis of distal radius fractures were detected in 5 of 119 treated cases in our clinic. The rupture of the extensor digitorum comm.dig. II tendon were most frequent followed by the rupture of the extensor pollices longus tendon. Partial ruptures of the extensor indicis tendon also have seen. All distal radius fractures cured regularly in time without any other complications. The ruptures occurred 3 to 60 weeks after initial treatment with a volar plate. The tendon repair surgery with the volar plate explantation in all cases has shown the mechanical irritation by prominent screws or bone fragments. Only one case of a extensor tendon rupture was caused by a mechanic irritation from a fracture fragment three weeks after osteosynthesis. Ra-diographs don’t expose prominent implantats or fracture fragments for a liability to tendon ruptures surely. To avoid extensor tendon ruptures a correct srew length implantation and a care-fully drilling is recommended. In spite of quite safely implants a scheduled explantation after regular healing of the fracture is to consider.
