Functional and electromyographic results after open rotator cuff repair.

Fifty-one patients treated for full-thickness rotator cuff tears were followed up an average of 4 years after surgery (range, 2-6.4 years). The shoulder function was assessed according to the Constant classification, each patient did strength measurements, and had electromyographic evaluation of the supraspinatus and infraspinatus muscles.

Efficacy and impact of monophasic versus biphasic countershocks for transthoracic cardioversion of persistent atrial fibrillation.

This report compares the cumulative efficacy of cardioversion and skeletal muscle injury after either damped sine wave monophasic or truncated exponential biphasic transthoracic cardioversion of persistent atrial fibrillation. The trial sought to refute the null hypothesis of therapeutic equivalence between monophasic and biphasic waveforms. Results of the study reveal similar cumulative efficacy of waveforms and greater levels of skeletal muscle damage when patients are younger and male, and when monophasic waveforms are used.

Late results of modified Mitchell procedure for the treatment of hallux valgus.

From a total of 153 patients (251 feet), 64 (41.8%) patients, who had had 105 modified Mitchell procedures, were clinically and radiographically examined with follow-up periods ranging from 15 to 24 years (mean, 21 years). Mean age at operation was 41 years (range, 12-64 years).

Displaced subcapital fracture of the hip in transient osteoporosis of pregnancy. A case report.

We describe a case of displaced subcapital fracture of the hip in a woman in the third trimester of her first pregnancy. A pathological fracture occurred in a previously painful hip, and radiographs showed pronounced osteopenia of the femoral head and neck. Closed reduction and internal fixation was carried out 2 weeks after delivery when the osteopenia was still severe.
