Abstract

In nonunion after distal humerus fracture, osteoporosis, devascularized fracture fragments, and periarticular fibrosis limit potential reconstructive options. We assessed pain relief, functional gains, and complications in 12 patients whose long-standing, painful nonunions after previous treatment with rigid internal fixation were reconstructed with a semiconstrained total elbow arthroplasty, frequently with a triceps-sparing approach and anterior ulnar nerve transposition. At mean follow-up of 63 months, 11 patients had good pain relief and a good or excellent functional result: mean flexion/extension, 134 degrees to 18 degrees; mean total arc of motion, 117 degrees ; mean pronation/supination, 74 degrees to 69 degrees. Despite the 75% rate of complications (8), semiconstrained total elbow arthroplasty provides a viable treatment for this difficult problem.
