What are the indications for shoulder replacement surgery? The most common indication for shoulder replacement remains primary glenohumeral osteoarthritis. Other indications include complex proximal humeral fractures, rheumatoid arthritis and other inflammatory arthropathies, humeral head osteonecrosis, instability arthropathy, posttraumatic arthritis, chronic fixed glenohumeral dislocation, ro...

BACKGROUND Shoulder activity level may be a risk factor for shoulder instability, an indication for surgical intervention, and a risk factor for failure of operative stabilization. HYPOTHESIS Patients undergoing shoulder stabilization surgery have a higher activity level compared with sex- and age-matched healthy controls. STUDY DESIGN Cross-sectional study. LEVEL OF EVIDENCE Level 2. M...

We reviewed 188 patients at one to 20 years (mean 9.5) after surgery for anterior shoulder instability. Twenty-one had shown bilateral instability at the time of surgery, and 26 of the remaining 167 subsequently developed instability of the contralateral shoulder, giving an overall incidence of 24% bilateral involvement. Fourteen of these patients ultimately required bilateral surgery. The onse...

BACKGROUND Surgical simulation has become increasingly relevant to orthopaedic surgery education and could translate to improved operating room proficiency in orthopaedic surgery trainees. PURPOSE To compare the arthroscopic performance of junior orthopaedic surgery residents who received training with a knee and shoulder arthroscopy surgical simulator with those who received didactic trainin...

Arthroscopic shoulder surgery with the patient in the beach-chair position (BCP) has been associated with neurocognitive complications caused by cerebral ischemia. We reviewed the current literature for the incidence of postoperative neurocognitive deficits, number of reported neurocognitive complications, and incidence of intraoperative cerebral desaturation events in patients who underwent ar...
