The rupture occurred in a proximal biceps tendon, resulting in retraction distally. This is one of the two forms of the "Popeye deformity." This image shows a biceps brachii tendon rupture on the left arm. The rupture occurred in the distal biceps tendon, resulting in retraction of the muscle belly proximally.
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.
MRI of normal shoulder intratendinous signal MRI of rotator cuff full-thickness tear. Magnetic resonance imaging and ultrasound [46] are comparable in efficacy and helpful in diagnosis, although both have a false positive rate of 15–20%. [47] MRI can reliably detect most full-thickness tears, although very small pinpoint tears may be missed.
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 ...
All of the tests take advantage of the fact that the labrum meets the tendon of the long head of the biceps muscle, and thus will normally produce pain in the region if a tear is present. Additionally, clinicians may order an MRI ( Magnetic Resonance Imaging ) or CT ( Computed Tomography ) scan to be conducted utilizing contrast injections to ...
It identifies the presence of a pathology involving the biceps tendon or glenoid labrum. The specific positive findings to the test include pain in the bicipital groove indicating biceps tendinitis, [2] [3] subluxation of the long head of the biceps brachii muscle, [3] and presence of a SLAP tear.

In disease or injury, this contrast fluid may either leak into an area where it does not belong, indicating a tear or opening, or be blocked from entering an area where there normally is an opening. MRI (magnetic resonance imaging)--A non-invasive procedure in which a machine produces a series of cross-sectional images of the shoulder.
Shoulder problems, including pain, are common [20] and can relate to any of the structures within the shoulder. [21] The primary cause of shoulder pain is a rotator cuff tear. [20] The supraspinatus is most commonly involved in a rotator cuff tear, [22] but other parts of the rotator cuff may also be involved.
