Shoulder pain has been cited as the third most common musculoskeletal pain complaint
with a prevalence between 7% and 30%. 1–5 Impingement syndrome is the most common …

Background Rotator cuff tears are common. A previous systematic review reported on factors
associated with rotator cuff tears; however, it included relatively few studies and few …

Background The purposes of this study were to determine whether acromial morphology (1)
could be measured accurately on magnetic resonance images (MRIs) as compared to …

Rotator cuff tears are a common condition of the shoulder, and 20.7% of people with the
condition have a full-thickness rotator cuff tear. The purpose of this study was to explore the …

Purpose Scapular morphology is an extrinsic factor playing role in rotator cuff tear (RCT)
etiology. The objective of this study was to evaluate the relationship between critical …

Hypothesis The concept of the critical shoulder angle (CSA) was introduced in 2013, with
studies showing that larger CSA is associated with rotator cuff tears (RCTs) and smaller CSA …

Purpose The critical shoulder angle (CSA) has been implicated as a potential risk factor for
failure following arthroscopic rotator cuff repair (RCR). However, there is conflicting …

Purpose Assessment on whether radiographic parameters of the acromion measured in
radiographs change significantly after anterolateral acromioplasty. Methods This …

Purpose The critical shoulder angle (CSA) and the acromion index (AI) are measurements of
acromial shape reported as predictors of degenerative rotator cuff tears (RCT) and …

Objectives: The literature indicates that reduced acromiohumeral distance (AHD) and
increased critical shoulder angle (CSA) are associated with large and massive rotator cuff …
