Injuries to the tissue surrounding the shoulder socket can be caused by acute trauma or repetitive shoulder motions. [4], Detachment of the glenoid labrum often requires surgery to reattach it to the glenoid fossa. The glenoid labrum is a fibrocartilaginous rim attached around the margin of the glenoid cavity. Complete detachment of the glenoid labrum from the superior pole of the glenoid, which is associated with a destabilization of the origin of the long biceps tendon, leads to altered function in the shoulder joint. __ tendon attaches on to labrum. The most common type of injury to the glenoid labrum involves tearing of some part of the cartilage ring. The socket is deepened by the glenoid labrum. adds stability. Morphology varies regionally, especially in the superior and anterior region; these variants can sometimes be confused with pathological aspects. The shoulder joint is considered a ball and socket joint. The average depth of the glenoid fossa is 2.5 mm, however, the labrum helps to increase this depth. Although the labrum increases the depth and volume of the glenoid fossa, it does not seem … Clinicians can use any combination of the following manual tests to assist in determining if a labral tear has occurred; Jobe Relocation, O'Brien, Anterior Apprehension, Bicipital Groove Tenderness, Crank, Speed, and Yergason tests. 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. First, the labrum deepens the concavity of the glenoid up to 9 mm in the superior-inferior direction and also doubles the antero-posterior depth to 5 mm [ 12 ]. Found inside â Page 117The glenoid fossa is deepened by the presence of a fibrocartilaginous rim, the glenoid labrum (Fig. 2.67C), which is triangular in cross-section; ... This glenoid is surrounded by fibrocartilagenous structure which acts as a support system for the glenoid. The superior labrum functions more as a mobile extension of the glenoid surface than as a stabilizing bumper that is seen in the inferior labrum.9 The loose superior labrum is anchored near the 10 o’clock and 2 o’clock positions,2,9 which may be something to Found inside â Page 241The glenoid labrum functions to deepen the glenoid fossa by 50%.3,4 It is also the attachment site for many of the glenohumeral ligaments.

According to some sources, the the overall strength of the capsule bears an inverse relationship to the patient's age; the older the patient, the weaker the Joint Capsule [2] . If there is an injury to the shoulder that tears the ligaments, sometimes the labrum is pulled off of the rim of the bone as well. it also covers The medial attachment of the joint capsule is the glenoid and the labrum. By deepening the glenoid fossa, it contributes to shoulder mechanics and prevents the humeral head from rolling out of the socket. Two op … The knee meniscus and glenoid labrum are anatomically distinct yet analogous structures. 26,27 The failures at the glenoid attachment can be separated into two categories: (1) the labrum was avulsed from the glenoid bone (63%); and (2) the labrum remained attached to the glenoid and the ligament alone was avulsed, representing failure at the ligament-to-labral junction (37%).

The labrum is important to overall hip health and function. Specifically, the labrum: Facilitates the hip's range of motion, allowing the thigh to rotate in every direction, including forward, backward, inward, and externally. In anatomy and physiology, the term 'labrum' is used to refer to an edge or a brim. Found inside â Page 57The labrum performs this important function in two ways.

The glenoid labrum is similar to the meniscus of the knee. https://orthopaedia.com/page/Disorder-of-the-Glenoid-Labrum The glenoid labrum is an integral component of the glenohumeral capsule's insertion into the glenoid, and changes in labrum geometry and mechanical properties may lead to the development of glenohumeral joint pathology. Tears are classified as either superior or inferior in regards to where the tear is in the glenoid cavity. If you could have any superpower, what would it be? The glenoid, or socket joint of the shoulder, is surrounded by a fibrocartilaginous supporting structure called the labrum. Specifically, it is the head of the humerus that contacts the glenoid cavity (or fossa) of the scapula. the glenoid labrum … Clinicians can use any combination of the following manual tests to assist in determining if a labral tear has occurred; Jobe Relocation, O'Brien, Anterior Apprehension, Bicipital Groove Tenderness, Crank, Speed, and Yergason tests. 2012;6(5):357-72. The glenoid labrum is essential for the structure and therefore the function of the glenohumeral joint. 50%. The glenoid labrum is a fibrous ring of tissue which attaches to the rim of the glenoid which is the shallow depression of the scapula or shoulder blade where the ball of the humerus sits. Although the gross anatomy differs, both tissues are composed of fibrocartilage with a complex but well-organized collagen microstructure. The labrum helps stabilize the joint and acts as a "bumper" to limit excessive motion of the humerus, the "ball" side of the shoulder joint. J Child Orthop.
