Arthritis affecting the shoulder includes osteoarthritis, rheumatoid arthritis, osteonecrosis, posttraumatic arthritis, cuff tear arthropathy, and post-capsulorrhaphy arthropathy. Primary osteoarthritis is the most common form and characterized as a slow progressing disease that leads to cartilage thinning and ultimately, complete cartilage loss resulting in bone on bone contact and pain. There are many risk factors for shoulder arthritis including age, sex, race, genetics, weight, trauma, dislocation, and history of previous surgery.
Glenohumeral instability is a common problem in the young, athletic patient population, with anterior instability being more common than posterior or multidirectional instability (MDI)66,72,225. The incidence of anterior glenohumeral instability in the United States population is 0.08 per 1,000 person-years175,256.
Introduction: Previous studies have examined the relationship between total hip arthroplasty (THA) and insurance status in small cohorts. This study evaluates the effect of patient insurance status on complications after primary elective THA using the Nationwide Inpatient Sample.
Shoulder arthroplasty procedures are increasingly being performed in older patients despite an increased perioperative risk. The purpose of this study is to determine the complications and 30-day readmission rates in the elderly population after shoulder arthroplasty and hemiarthroplasty.
Introduction: Comparative trials evaluating categorical outcomes have important implications on surgical decision making. The purpose of this study was to examine the statistical stability of sports medicine research.
Osteonecrosis is caused by diminished microperfusion of bone resulting in subsequent joint collapse. Estimates suggest that roughly 20,000 to 30,000 new cases are diagnosed annually in the United States, with even higher rates in other countries.
In this review, we describe the history of the Critical Shoulder Angle (CSA), the utility of the CSA in identifying rotator cuff tears and glenohumeral osteoarthritis, and the association between the CSA and patient-reported outcomes. Additionally, we address some of the controversies surrounding the CSA with an updated literature review.
The epidemiology of MRI detected shoulder injuries in athletes participating in the Rio de Janeiro 2016 Summer Olympics
Background: To use Magnetic Resonance Imaging (MRI) to characterize the severity, location, prevalence, and demographics of shoulder injuries in athletes at the Rio de Janeiro 2016 Summer Olympic Games.
Anterior Cruciate Ligament Reconstruction With Achilles Tendon Allograft in a Patient With Ehlers-Danlos Syndrome
Ehlers-Danlos Syndrome (EDS) can cause recurrent dislocation and subluxation of joints due to ligamentous and capsular laxity, often leading to surgical interventions. Graft choice for ACL reconstruction is particularly important for EDS patients, since autograft options will increase risk of failure due to the abnormally lax tissue quality in these patients; however, few studies discuss considerations for EDS patients undergoing ACL reconstruction.
Adhesive capsulitis is characterized by a gradual, painful loss of shoulder motion. This study evaluated patient variables significantly associated with developing adhesive capsulitis compared with a sex-matched control group without adhesive capsulitis. We also sought to determine those factors associated with adhesive capsulitis patients requiring surgical intervention.
