Complex fractures of the proximal humerus: role of CT in treatment.
The authors reviewed the computed tomography (CT) scans, plain radiographs, and subsequent treatment of 17 patients with complex proximal humeral fractures. CT scans and radiographs were compared in the demonstration of fracture lines, displacement of fracture fragments, rotation of fragments relative to their normal positions, and status of the head and articular surface of the humerus. The impact of CT findings on the decision to treat with surgery versus closed reduction and on the choice of surgical procedure was assessed. Surgery was not performed in nine patients because CT scans showed no significant displacement of fragments previously judged displaced or "indeterminate" on radiographs. Surgery was performed in eight patients; CT demonstrated significant abnormalities not definitely shown with radiography. In six of these eight patients, CT scans demonstrated unsuspected abnormalities that directed the choice of surgical procedure. CT scans provide clinically useful information for the treatment of complex proximal humeral fractures when radiographs provide inadequate or indefinite information.
