Labral reconstruction with iliotibial band autografts and semitendinosus allografts improves hip joint contact area and contact pressure: an in vitro analysis.

Background: Labral reconstruction using iliotibial band (ITB) autografts and semitendinosus (Semi-T) allografts has recently been described in cases of labral deficiency.

Purpose/hypothesis: To characterize the joint biomechanics with a labrum-intact, labrum-deficient, and labrum-reconstructed acetabulum in a hip cadaveric model. The hypothesis was that labral resection would decrease contact area, increase contact pressure, and increase peak force, while subsequent labral reconstruction with ITB autografts or Semi-T allografts would restore these values toward the native intact labral state.

Scapulothoracic anatomy and snapping scapula syndrome.

The scapulothoracic articulation is a sliding junction between the deep aspect of the scapula and thoracic rib cage at the levels of ribs 2 through 7. Motion at this articulation is dynamically stabilized by a variety of muscular attachments, allowing for controlled positioning of the glenoid to assist in glenohumeral joint function. A thorough understanding of the complex anatomic relationships, including the various muscles, and bursa, is critical to the evaluation of patients presenting with scapulothoracic disorders.

Isolated vastus lateralis tendon avulsion.

Isolated avulsion of the vastus lateralis tendon is a very rare injury. To our knowledge, only 1 case has been reported in the literature. This tendon is crucial to knee stability and proper patellofemoral tracking.

Arthroscopic bony bankart fixation using a modified sugaya technique.

Arthroscopic fixation of bony Bankart lesions in the setting of anterior shoulder instability has had successful long-term results.
