MR imaging of rotator cuff injury: what the clinician needs to know. It corresponds to a synovial reflection medial to the superior edge of the glenoid rim at the biceps anchor, showing a normal defect of the attachment of the superior labrum to the superior glenoid cartilage. On the other hand, the subscapularis muscle originates from the subscapular fossa of the scapula and its wide tendon inserts in the lesser tuberosity, separated from the insertion of the other rotator muscles by the rotator interval. Type I has a flat under surface, type II a concave under surface and type three a concave under surface with anterior hook.

MR arthrography is the most sensitive and specific technique for diagnosing both full-and partial-thickness rotator cuff tears. It provides stability of the glenohumeral joint, restricting anterior and posterior displacement of the humeral head. Persistent shoulder pain: epidemiology, pathophysiology, and diagnosis.

Chronic forms are associated with thickening tendinosis [ 34 ]. Figure 12 Schematic illustration of the normal capsulolabral complex and anatomical variations. In addition, specific injuries of the rotator cuff tendons and the condition of the long head of biceps should be accurately reported.

Diagnosis was confirmed by ultrasonography. Avulsion is diagnosed by noting the absence of the intra-articular segment of the tendon with no signs of dislocation. Supraspinatus tendinosis A. A well-structured MRI report should include full comment on the rotator cuff tendons and all other relevant structures.

The sublabral foramen should not be confused with an anterosuperior labral tear in patients with clinical symptoms. The anterior capsular insertion can be subdivided into three types depending on the proximity of the capsular insertion to the glenoid margin.

MRI can differentiate joint enlargement due to capsular hypertrophy intermediate signal intensity form joint effusion bright signal on T2-weighted images. Continuous advances in MRI field strength, gradients, and coil technology have allowed even more accuracy for conventional MRI than that reported in the early literature, and conventional MRI is still the most commonly used technique for diagnosis of rotator cuff tears[ 3 , 11 , 12 ]. Conventional MRI is the most commonly used technique, while magnetic resonance MR arthrography is reserved for certain cases. The infraspinatus and teres minor muscles are best demonstrated on axial images as fusiform intermediate signal intensity structures parallel and inferior to the supraspinatus.
