Indications: rheumatoid arthritis, post-traumatic arthritis, complex distal humerus fractures in elderly, tumor resection. Implant types: linked (semi-constrained), unlinked (requires intact ligaments), convertible designs. Linked implants provide stability but ↑ stress at bone-cement interface; unlinked mimic anatomy but require ligamentous integrity. Complications: loosening, infection, triceps insufficiency, periprosthetic fracture, ulnar nerve palsy. Survivorship: 85–90% at 10 years with careful patient selection.
