Total elbow replacement for distal humerus fractures and traumatic deformity: results and complications of semiconstrained implants and design rationale for the Discovery Elbow System.
Recent advances in elbow replacement design have further extended its usefulness as an expedient reconstructive method for restoring elbow function following trauma. This is particularly true in elderly patients, for whom treatment is complicated by the frequent presence of osteoporosis, severe comminution with small condylar fracture fragments, and diminished bone-healing capacity. This article addresses the role of elbow replacement for fracture, traumatic deformity, post-traumatic arthritis, and instability. Indications, techniques, and results are presented. Complications of semiconstrained implants are presented, and the design rationale for, and examples of, the latest-generation Discovery Elbow System (Biomet Orthopedics, Warsaw, Indiana) are discussed.
