Arthroscopic repair of medium to large full-thickness rotator cuff tears: outcome at 2- to 6-year follow-up.

Medium-term follow-up of arthroscopic rotator cuff repair was evaluated in 48 consecutive arthroscopic repairs of medium to large rotator cuff tears. Mean rotator cuff tear size was 2.4 cm (range, 2-4 cm), mean age at surgery was 57.

Superior labral lesions in the shoulder: pathoanatomy and surgical management.

Progress in shoulder arthroscopy has led to the identification of previously undiagnosed lesions involving the superior labrum and the biceps tendon anchor. Additional research has substantiated the role of the long head of the biceps tendon in anterior and rotational glenohumeral stability. Careful attention to the history and physical examination and directed diagnostic imaging may arouse suspicion of injury to the biceps tendon and the superior labral complex.

Avascular necrosis of the femoral head after closed intramedullary shortening in an adolescent.

Closed intramedullary shortening has become a popular treatment method for limb-length inequality in adolescents. An important, potentially devastating complication of closed intramedullary fixation only recently described is avascular necrosis of the femoral head. We believe alternative treatment options must be considered to avoid this irreversible and catastrophic complication.

The contribution of the glenohumeral ligaments to anterior stability of the shoulder joint.

The purpose of this study was to investigate the ligamentous stabilizing mechanisms preventing anterior instability in the glenohumeral joint. Six freshly thawed, unembalmed cadaveric shoulders were dissected, preserving the joint capsule and glenohumeral ligaments, the coracohumeral ligament, and the subscapularis tendon. Hall-effect strain transducers were placed on the superior, middle, and inferior glenohumeral ligaments.

Long-term follow-up of patients treated with coronary angioplasty for acute myocardial infarction.

Long-term follow-up data for patients treated with coronary angioplasty (PTCA) for acute myocardial infarction are limited. Therefore the long-term outcome of 336 consecutive patients treated with PTCA at a median of 4.5 hours (range 0.
