Ellengelenknahe Unterarmfrakturen

Abstract

Fractures of the forearm close to the elbow are relatively rare, accounting for approximately 7% of all fractures. Of those sited in the proximal forearm, about 38% involve the olecranon and 20-30%, the radial head. The AO classification of forearm fractures in close proximity to the elbow has not attained general acceptance. Classifications with implications for the treatment are most commonly used. For fractures of the olecranon, we prefer the classification devised by Schatzker, since it takes account of the course of the fracture and the number of bone fracture fragments and therefore dictates what type of osteosynthesis is needed. The Mason classification has become widely accepted for fractures of the radial head. Depending on the type of fracture, conservative treatment, an operative procedure or a resection is recommended. Fractures of the coronoid process are classified with reference to Regan and Morrey's system. The size of the fracture fragment is used as an indirectly indicator of the stability of the joint and thus of what operative intervention is needed. In addition to Monteggia's fracture, Essex-Lopresti fracture and the terrible triad of the elbow are also discussed in detail. © Springer Medizin Verlag 2007.
