A line crossing the center of a line between the superior and inferior rims of the glenoid articular surface (blue in image). The center of a "best-fit" circle positioned over the humeral articular surface (green in image) Normally, the former is positioned inferiorly to the latter, and a reversal therefore indicates a rotator cuff tear.

The lateral meniscus is grooved laterally for the tendon of the popliteus, which separates it from the fibular collateral ligament.. Its anterior end is attached in front of the intercondyloid eminence of the tibia, lateral to, and behind, the anterior cruciate ligament, with which it blends; the posterior end is attached behind the intercondyloid eminence of the tibia and in front of the ...
A Bankart lesion is a type of shoulder injury that occurs following a dislocated shoulder. [3] It is an injury of the anterior glenoid labrum of the shoulder. [4] When this happens, a pocket at the front of the glenoid forms that allows the humeral head to dislocate into it.
A SLAP lesion (superior labrum, anterior to posterior) is a tear where the glenoid labrum meets the tendon of the long head of the biceps muscle. Symptoms include increased pain with overhead activity, popping or grinding, loss of strength, and trouble localizing a specific point of pain. [ 3 ]
An articular cartilage defect that initially may be small still has the potential to have a physical and chemical "domino effect" on the surrounding "normal" articular cartilage. [2] Pitkin et al. (2014) discovered a potential etiology for articular cartilage damage. When the interarticular transmission of pressures is interrupted so that ...
The labrum contributes to the articular surface of the joint [2] [1] (increasing it by almost 10% [1]). It embraces the femoral head , [ 2 ] holding it firmly in the joint socket [ 3 ] to stabilise the joint.
The articular surfaces were notably different in size and form. On some, they are separated by a meniscus attached to the superior acromioclavicular ligament. This meniscus may be a blade of fibrocartilage that extends nearly halfway into the joint or it may form a complete disc that divides the joint into two parts.
The role of the Hill-Sachs in continuing symptoms, in turn, may be related to its width and depth, particularly if involving greater than 20% of the articular surface. Associated bony lesions or fractures may coexist in the glenoid such as the bony Bankart lesion.
