N2 - 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.
