The humeral head may migrate upward (high-riding humeral head) secondary to tears of the infraspinatus, or combined tears of the supraspinatus and infraspinatus. [51] The migration can be measured by the distance between: A line crossing the center of a line between the superior and inferior rims of the glenoid articular surface (blue in image).
The rotator interval is a triangular space in the shoulder that is functionally reinforced externally by the coracohumeral ligament and internally by the superior glenohumeral ligament, and traversed by the intra-articular biceps tendon. On imaging, it is defined by the coracoid process at its base, the supraspinatus tendon superiorly and the ...
The supraspinatus is most commonly involved in a rotator cuff tear, [22] but other parts of the rotator cuff may also be involved. There are different severities of a rotator cuff tear, which range from a partial tear to a full-thickness tear. [23] A partial tear is when the tendon is thinned, but still connected to the bone.
Axillary pouch of the shoulder can be seen on external rotation, while subscapular (subcoracoid) bursa can be seen on internal rotation of arm. The contrast should not enter subacromial bursa unless supraspinatus tendon is completely ruptured. [4] MRI with surface coils is used to image the shoulder joint. [4]
The diagnosis is usually initially made by a combination of physical exam and medical imaging, where the latter may be projectional radiography (in cases of bony Bankart) and/or MRI of the shoulder. The presence of intra-articular contrast allows for better evaluation of the glenoid labrum. [8] Type V SLAP tears extends into the Bankart defect. [9]
Hollowing in the supraspinous and the infraspinous area is frequently seen as chronic rotator cuff tear resulting in wasting. [2] The wasting may be caused by the supraglenoid cyst compressing the suprascapular nerve and causes a loss of innervation to supraspinatus and infraspinatus muscles.
MRI showing subacromial impingement with partial rupture of the supraspinatus tendon, but no retraction or fatty degeneration of the supraspinatus muscle. Impingement syndrome can be diagnosed by a targeted medical history and physical examination , [ 11 ] [ 12 ] but it has also been argued that at least medical imaging [ 13 ] (generally X-ray ...
Calcification of the supraspinatus tendon is a major contributor to shoulder pain in the general population and is often worsened following a supraspinatus tear. The results of the study included the return to sports and original functionality of 95.8% of the patients after a mean of 5.3 post-operative months.
