Anterior Hip Dislocation After Hip Arthroscopy Complicated by Iliopsoas Bursitis.

Hip dislocation after hip arthroscopy is an uncommon postoperative complication. We report a case of a 51-year-old woman who underwent right hip arthroscopy and presented with an anterior hip dislocation on postoperative day five. The index surgery involved capsulotomy, cam lesion debridement, and femoroplasty for an anterosuperior labral tear and cam-type femoroacetabular impingement.

The deltoid muscle origin. Histologic characteristics and effects of subacromial decompression.

The histologic characteristics of the deltoid muscle attachment to nine cadaveric acromia were studied using light microscopy. The deltoid muscle attaches to the anterior and lateral acromion primarily by direct tendinous attachment. The muscle attaches to the dorsal side of the acromion by periosteal fiber attachment.

Reliability of radiographic evaluation for acromial morphology.

Objective: Bigliani's classification system of acromial morphology utilizing the standard outlet radiograph has become in accepted method for evaluating patients with rotator cuff disease. This study evaluates the interobserver and intraobserver reliability of Bigliani's classification system using observers at various levels of training.

Patients And Design: Supraspinatus outlet view radiographs of 40 patients (aged 18-78 years) with shoulder pain were reviewed twice, 4 months apart, in a masked protocol by six reviewers, including two attending (fellowship-trained) shoulder surgeons, an attending musculoskeletal radiologist, an orthopedic surgery sports fellow, and two orthopedic residents (PGY-2 and PGY-5).

Evaluation of shoulder laxity.

An understanding of the anatomy and biomechanical features of the glenohumeral joint is necessary when understanding the concept of shoulder laxity. Glenohumeral laxity is a normal feature of shoulder motion, but only when that laxity becomes excessive does instability occur. The clinician must use the history and physical examination to distinguish normal from pathological laxity.

Femoral interference screw placement through the tibial tunnel: a radiographic evaluation of interference screw divergence angles after endoscopic anterior cruciate ligament reconstruction.

Fifty patients who underwent single-incision arthroscopically assisted anterior cruciate ligament (ACL) reconstruction using bone-patellar tendon-bone autograft were reviewed. All procedures were performed using a technique for placement of the femoral interference screw that reduced the divergence between the femoral interference screw and the femoral bone plug. This technique includes securing the femoral interference screw by placing the screw driver through the tibial tunnel, anterior to the tibial bone plug.
