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.
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 ...
On non-contrast MRI or CT arthrography imaging, lesions might be harder to find, but the more recent 3T MRI scanners might increase the pick-up rate in the absence of contrast. [4] The accepted gold standard for identifying or detecting the glenolabral articular disruption lesion is MR arthroscopy (MRA). [1]
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.
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 supraglenoid tubercle is a region of the scapula from which the long head of the biceps brachii muscle originates. [1] [2] It is a small, rough projection superior to the glenoid cavity near the base of the coracoid process. The term supraglenoid is from the Latin supra, meaning above, and glenoid, meaning socket or cavity. [3]
