    Abstract Etiologies of elbow contractures can be classified into intrinsic versus extrinsic causes. Posttraumatic elbow stiffness is the most common intrinsic cause and HO formation is the most common extrinsic cause of elbow contractures. Patients who sustain significant elbow trauma and have one or more risk factors for HO formation should be given prophylaxis against HO formation in the form of either indomethacin or radiation therapy. Early excision of HO has been shown to be safe and effective. Nonoperative measures are most effective if used within 6 months of contracture onset. These measures include physical therapy and an aggressive splinting program. If nonoperative measures are unsuccessful and the patient has functionally limiting elbow ROM, then surgical intervention should be considered. Careful preoperative assessment of the ulnar nerve is mandatory, as it may need to be transposed. Satisfactory results have been reported with arthroscopic elbow contracture releases. However, this procedure is technically challenging, with the potential for serious neurovascular complications. Satisfactory results have been published for open procedures as well. The direction of the greatest limitation of motion, the presence of ulnar nerve dysfunction, and the location of osteophytes all help to dictate which surgical approach should be selected.

    Abstract It has recently been suggested that peripheral nerve or plexus blocks performed with the use of a nerve stimulator at low currents (<0.5 mA) may result in neurologic damage. We studied the infraclavicular nerve block, performed with the use of a nerve stimulator and an insulated needle, in a prospective evaluation of efficacy and safety. During a one-year period, 248 patients undergoing infraclavicular nerve block were evaluated for block success rate and incidence of neurologic complication. All blocks were performed with the use of a nerve stimulator and an insulated needle at < or =0.3 mA. Success rate was 94%, which increased to 96% with surgical infiltration of local anesthetic. There were no intraoperative or immediate postoperative complications noted. After one week, only one patient had a neurologic complaint, and this was surgically related, referable to surgery performed on the radial nerve. We conclude that infraclavicular nerve blocks performed at low currents (< or =0.3 mA) are safe and effective.
