Winkelstabile Plattenosteosynthese für proximale Humerusfrakturen : Konzept und Ergebnisse

Abstract

Fractures of the proximal humerus is one of the most common injuries suffered by humans, and its incidence is increasing rapidly, especially in elderly women. The main risk factor is osteoporosis, so that internal fixation of the eggshell-shaped fragments is the main challenge in its surgical treatment. In view of the high rate of necrosis of the humeral head and the unsatisfactory functional results, the old T-plate was replaced with "less invasive" procedures. For the three- and four-part humeral head fractures, fixed-angle plates are used with increasing frequency for internal fixation. Third-generation plates with polyaxial screws have already been developed. Initial studies with first-generation fixed-angle plates showed that the complication rate is still between 10% and 25% and that the Constant score in follow-up studies is betweeb 65% and 83%. © 2008 Springer Medizin Verlag.
