Total Elbow Arthroplasty

Total elbow arthroplasty has continued to evolve over time. Elbow implants may be linked or unlinked. Unlinked implants are attractive for patients with relatively well preserved bone stock and ligaments, but many favor linked implants, since they prevent instability and allow replacement for a wider spectrum of indications. Inflammatory arthropathies such as rheumatoid arthritis represent the classic indication for elbow arthroplasty. Indications have been expanded to include posttraumatic osteoarthritis, acute distal humerus fractures, distal humerus nonunions and reconstruction after tumor resection. Elbow arthroplasty is very successful in terms of pain relief, motion and function. However, its complication rate remains higher than arthroplasty of other joints. The overall success rate is best for patients with inflammatory arthritis and elderly patients with acute distal humerus fractures, worse for patients with posttraumatic osteoarthritis. The most common complications of elbow arthroplasty include infection, loosening, wear, triceps weakness and ulnar neuropathy. When revision surgery becomes necessary, bone augmentation techniques provide a reasonable outcome

Bilateral plate fixation for type C distal humerus fractures: experience at a single institution

Type C fractures of the distal humerus are difficult to treat and typically require open anatomical reduction and internal fixation. Here we describe our experience treating patients with type C distal humerus fractures using a trans-olecranon approach with bilateral plate fixation. Fifty-six patients (30 males, 26 females; mean age 49.8 years) were treated over a period of six years. Thirteen fractures were open and 43 closed; all were caused by falls or traffic accidents. All operations were performed successfully with no intraoperative complications. Mean duration of follow-up was 30 months (range 6–70). Mean duration of fracture healing was 2.8 months (range 2–4). Forty-seven out of 56 patients (84%) suffered no postoperative complications. One patient exhibited symptoms of ulnar nerve injury following surgery (nine exhibited symptoms before and after surgery). Two patients had mild cubitus varus deformities, four delayed olecranon osteotomy site healing, and two heterotopic ossifications. In summary, complications were minimal and outcomes satisfactory in patients with type C distal humerus fractures who underwent bilateral plate fixation via a trans-olecranon approach
