Suprascapular nerve compression is rare and should be considered in the differential diagnosis of patients with shoulder pain and external rotation deficit. Spinoglenoidal cysts may cause compression, and posterosuperior glenoid labrum lesions are the most likely hypothesis to explain their appearance. Magnetic resonance imaging and electromyography define the diagnosis. Indirect arthroscopic d...

We sought to understand the effects of superior humeral head translation and load of the long head of biceps on the pathomechanics of the superior glenoid labrum by predicting labral strain. Using micro-CT cadaver images, a finite element model of the glenohumeral joint was generated, consisting of humerus, glenoid bone, cartilages, labrum, and biceps tendon. A glenohumeral compression of 50 N ...

The Hill-Sachs lesion is an osseous defect of the humeral head that is typically associated with anterior shoulder instability. The incidence of these lesions in the setting of glenohumeral instability is relatively high and approaches 100% in persons with recurrent anterior shoulder instability. Reverse Hill-Sachs lesion has been described in patients with posterior shoulder instability. Gleno...

Lesions of the glenoid labrum are a common cause of shoulder instability and a frequent finding in patients with shoulder pain. Management of these patients typically involves an attempt to avoid surgery through conservative treatment. However, there is currently a dearth of conservative options that promote labral healing. Regenerative injection therapies, including prolotherapy, have shown pr...

Background: Managing posterior glenoid wear and retroversion remains a challenge in shoulder arthroplasty.Correcting glenoid version through asymmetric reaming (AR) with placement of a standard glenoid component and theuse of posteriorly augmented glenoid (PAG) components are two methods used to address this problem. Our objectiveis to report the radiographic outcomes of patie...

BACKGROUND Patients who suffer anterior shoulder dislocations are at higher risk of developing glenohumeral arthropathy, but little is known about the initial cartilage damage after a primary shoulder dislocation. T1ρ is a magnetic resonance imaging (MRI) technique that allows quantification of cartilage proteoglycan content and can detect physiologic changes in articular cartilage. PURPOSE T...

BACKGROUND Bony augmentation of the anterior glenoid is used in athletes with recurrent shoulder instability and bone loss; however, the prevalence and impact of repair in elite American football athletes are unknown. PURPOSE To evaluate the prevalence and impact of glenoid augmentation in athletes invited to the National Football League (NFL) Scouting Combine from 2012 to 2015. STUDY DESIG...

PURPOSE With the increasing use of shoulder arthroscopy, diagnosis of glenoid labral lesions has become increasingly common. However, a physical examination maneuver that would allow a definitive clinical diagnosis of a glenoid labral tear, and more specifically a SLAP lesion, has been elusive. This study correlated the results of commonly used examination maneuvers with findings at shoulder ar...
