Abstract
Six elderly patients (average age, 68 years) were treated for a complex, low supracondylar nonunion of the humerus. Each nonunion had in common an associated ulnar neuropathy, extensive periarticular fibrosis, a low synovial nonunion, and osteopenic bone. The surgical approach included ulnar nerve neurolysis, complete elbow capsulectomy, three strategically placed plates, and autogenous iliac crest bone graft. All the nonunions healed and all six patients regained ulnar nerve function. The average arc of elbow motion was 102°, with an average flexion of 122° and a flexion contracture of 19°. Radiographic follow-up revealed only one case with a focal area of avascular necrosis involving a previously ununited intraarticular fracture of the trochlea.
