Function of supraspinatus muscle
with torn cuff Evaluated by Magnetic Resonance Imaging.
A complete tear of supraspinatus muscle
occurred in 55% of the cases, a partial tear of supraspinatus muscle
happened in 15%, a complete tear of the tendon of supraspinatus and subscapularis muscles was in 20%, and a complete tear of supraspinatus and infraspinatus muscles occurred in 10% of the cases.
Additionally, an MRI was scheduled demonstrating a partial thickness tear of the supraspinatus tendon, fluid in the subacromial/subdeltoid bursa compatible with shoulder impingement and moderate degenerative changes at the acromioclavicular joint encroaching upon the supraspinatus muscle
The test is considered positive for a supraspinatus muscle
tear if the patient is unable to keep the arm elevated after the physician releases the arm.
Isolated supraspinatus muscle
atrophy and fatty infiltration associated with recurrent anterior shoulder instability: A case report and review of the literature.
Primary intramuscular hydatidosis of supraspinatus muscle
. Arch Orthop Trauma Surg.2001;121: 93-948.
The supraspinatus muscle
arises from the posterior aspect of the scapula, just above the scapular spine, and courses horizontally and anteriorly at the level of the acromioclavicular joint, a good landmark for its musculotendinous junction.
Local peri-scapular wasting, especially the supraspinatus muscle
, viewed from above brings suprascapular nerve entrapment into the differential diagnosis.
SIS presents in many forms including bursitis and degenerative tendinitis and can lead to partial or full-thickness ruptures of the supraspinatus muscle
