In distal intraarticular humerus fractures primary stable osteosynthesis is essential for early mobilization of the elbow joint. Double-plate osteosynthesis techniques using different configurations are the gold standard. In the literature plate position is sometimes discussed controversially. In cases of distal humerus fractures (type AO 13C3) with metaphyseal comminution, as well as in elderly patients with poor bone quality, utilizing locking plates with angular stability was found to have increased structural properties with regard to primary fixation stability. The dorsal approach with osteotomy of the olecranon seems to be very effective in open reduction and internal fixation of this type of fracture. One new development is the anatomically preformed plate-fixation systems such as the LCP-System for distal humerus (Synthes). This study presents our first experience with this system in 11 cases of open reduction and internal fixation of type AO 13C3 distal humerus fractures. The system-specific features and intraoperative options were analyzed.
