“…I solated tears of the subscapularis tendon usually are related to trauma [1]. Subscapularis tendon abnormalities are more commonly associated with supraspinatus tendon abnormalities [2][3][4] and also have been associated with a narrowed coracohumeral distance [5]. Subscapularis tendon tears may go undiagnosed because of their rarity and variable clinical presentation [6].…”

“…Several studies have shown an association between supraspinatus and subscapularis tendon tears [2][3][4]. Li et al [2] found that nearly 80% of subscapularis tendon tears were associated with supraspinatus tendon tears and concluded that these tears were extensions of supraspinatus tendon tears.…”

“…Li et al [2] found that nearly 80% of subscapularis tendon tears were associated with supraspinatus tendon tears and concluded that these tears were extensions of supraspinatus tendon tears. Bergin et al [3] and MacMahon et al [4] concluded that subscapularis tendon tears are frequently associated with supraspinatus muscle atrophy and tendon retraction, respectively. Although the two previously mentioned studies reported an abnormally decreased coracohumeral distance, no significant relationship was found between the measured distance and the severity of the subscapularis tendon tears.…”

“…2,12,35 Subcoracoid Impingement Subcoracoid impingement is currently the subject of much debate in the orthopaedic and radiological literature. 11,[41][42][43] It remains unclear whether subcoracoid impingement should be considered a separate entity or a medial forme fruste of SIS. 11 Isolated SUB tears are being increasingly diagnosed at arthroscopy and MRI, with a reported incidence as high as 27%.…”

“…41 A relationship also exists between a narrow coracohumeral interval and the presence of full-thickness SST tears due to anterosuperior humeral migration. 42 This suggests that a secondary subcoracoid impingement may occur in the older age group resulting in SUB degeneration. Secondary subcoracoid impingement may also be a potential cause for persistent anterior shoulder pain following SST repair.…”

The relationship between external shoulder impingement and rotator cuff disease has been the subject of much research, but the theories of cause and effect remain controversial. Patients with symptoms of external impingement are referred for imaging to identify bony abnormalities of the coracoacromial arch and associated bursal and rotator cuff disease. Attempts have been made to identify objective imaging criteria that confirm the diagnosis of impingement, but at present external impingement remains primarily a clinical diagnosis. Therapeutic management varies from rehabilitation with physiotherapy to surgical procedures aimed at decompressing the subacromial space and repairing rotator cuff tears. This article reviews the relevant anatomy, biomechanics, and theories of external impingement, the role of imaging in the diagnosis of external impingement and rotator cuff disease, and implications upon management.

The subscapularis muscle: A meta‐analysis of its variations, prevalence, and anatomy

et al. 2023

View full text Add to dashboard Cite

Background: The subscapularis (SSC) is the largest rotator cuff muscle and is involved in the medial rotation, abduction, adduction, and anterior stabilization of the shoulder. It is anatomically variable, as is the morphology and prevalence of the accessory SSC (aSSC), a rare muscle slip attached to the SSC. There is no current review investigating the prevalence and morphometrics of the SSC and aSSC.Purpose: To investigate the prevalence of the morphological variants of the SSC and aSSC via meta-analysis and review the relevant literature involving cadaveric, magnetic resonance imaging, and ultrasonographic studies.
