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.

Ulnar nerve laceration in a closed both bone forearm fracture.

Ulnar nerve injury is rarely associated with closed forearm fractures. This report describes a case of ulnar nerve laceration secondary to a closed fracture of the radius and ulna. Although a case report of an ulnar nerve laceration in an open fracture has been described, a review of the literature failed to reveal any cases in closed injuries.

The use of MRI-compatible titanium segmental spinal instrumentation in pediatric patients with intraspinal tumor.

Severe kyphosis is a frequent complication of multiple laminectomies for the treatment of intraspinal tumors in growing children. Early Segmental Spinal Instrumentation (SSI) and posterior spinal fusion can prevent this complication, but because of ferromagnetic properties of conventional stainless steel implants, magnetic resonance imaging (MRI) performed to determine completeness of the resection and later for recurrence of the tumor becomes difficult. To overcome the problems with postoperative imaging, we have resorted to early stabilization of the spine following laminectomy with titanium alloy implants.
