A SLAP tear or SLAP lesion is an injury to the superior glenoid labrum (fibrocartilaginous rim attached around the margin of the glenoid cavity in the shoulder blade) that initiates in the back of the labrum and stretches toward the front into the attachment point of the long head of the biceps tendon.
The rotator cuff also reinforces this joint more specifically with the supraspinatus tendon to hold the head of the humerus in the glenoid cavity. The cavity surface is covered with cartilage in the fresh state, and its margins, slightly raised, give attachment to a fibrocartilaginous structure, the glenoid labrum, which deepens the cavity ...
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 ...
The clavicle and under surface of the deltoid muscle are above it. [citation needed] The tendon of the supraspinatus muscle (and its bursa) are below it. [2] Its lateral border is continuous with a dense lamina that passes beneath the deltoid muscle upon the tendons of the supraspinatus and infraspinatus muscle.
When this happens, a pocket at the front of the glenoid forms that allows the humeral head to dislocate into it. It is an indication for surgery and often accompanied by a Hill-Sachs lesion, damage to the posterior humeral head. [5] A bony Bankart is a Bankart lesion that includes a fracture of the anterior-inferior glenoid cavity of the ...
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 tests differ in the rotation of the arm; in the empty can test, the arm is rotated to full internal rotation (thumb down) and in the full can test, the arm is rotated to 45° external rotation, thumb up. [1] Once rotated, the clinician pushes down on either the wrists or the elbow, and the patient is instructed to resist the downward pressure.
It is in relation, above, with the clavicle and under surface of the deltoid; below, with the tendon of the supraspinatus, a bursa being interposed. [3] Its lateral border is continuous with a dense lamina that passes beneath the deltoid upon the tendons of the supraspinatus and infraspinatus.
