Purpose  The aim of this study was to compare the accuracy of the coracoid bone graft placement with the open Latarjet-Patte and arthroscopic Latarjet (arthro-Latarjet) procedures in the treatment of anterior instability of the shoulder. Methods  Forty-six patients affected by anterior shoulder instability were divided into two groups. In group A ( n  = 25), patients were operated by arthroscop...

Mild to moderate glenohumeral osteoarthritis (GHOA) is a common finding among patients who are evaluated for rotator cuff (RC) tears. However, the impact of pre-operative shoulder joint degeneration on patient-reported outcomes (PROs) following RC repair (RCR) not well-established. Certain studies have reported negative association between radiographic findings and RCR PROs, while other found n...

OBJECTIVE To investigate passive and active glenohumeral stiffness in the anterior, posterior, superior, and inferior directions at different lateral positions of the humerus. DESIGN Glenohumeral stiffness along multiple axes was determined in fresh-frozen shoulder specimens under both passive (no simulated muscle contraction) and active (with simulated muscle contraction) conditions. BACKG...

Background Recently, the 3-dimensional (3D) morphology of coracoacromial complex in nonpathologic shoulders has been described. The aim this study was to evaluate and compare pathologic (glenohumeral osteoarthritis [GHOA] cuff tear arthropathy [CTA]) shoulders. Methods A 3D computed tomography reconstruction 205 scapulae performed (49 with GHOA, 48 CTA, 108 normal [NL]). Subsequently, center gl...

STUDY DESIGN Cross-sectional. OBJECTIVES To compare differences in glenohumeral joint angular motion and linear translations between symptomatic and asymptomatic individuals during shoulder motion performed in 3 planes of humerothoracic elevation. BACKGROUND Numerous clinical theories have linked abnormal glenohumeral kinematics, including decreased glenohumeral external rotation and increa...

OBJECTIVE To review some of the important biomechanical factors that provide glenohumeral stability, along with the pathologic mechanisms involved in glenohumeral instability of the shoulder. DATA SOURCES Current English medical literature concerning the multiple pathologic factors involved in glenohumeral instability was reviewed. DATA SYNTHESIS Multiple dynamic and static factors control ...
