eMedicine - Superior Labrum Lesions : Article Excerpt by Riley J Williams An improved understanding of the surgical anatomy and the biomechanical contributions of the superior labrum have demonstrated its significance in shoulder stability and its role in the pathogenesis of shoulder pain. This tendon arises from the supraglenoid tubercle, and fibers from the superior labrum attach to the biceps tendon in this region. The glenoid labrum increases the area and depth of the glenoid cavity, contributing to articular stability of the glenohumeral joint. www.emedicine.com /sports/byname/Superior-Labrum-Lesions.htm   (2128 words)

Labral Findings: Normal vs. Pathological --- A. Castagna   (Site not responding. Last check: 2007-10-08) The labrum is a fibrous structure strongly attached around the glenoid edge (1) that increases the contact surface between the glenoid itself and the humeral head. Histologically the attachment of the labrum to the glenoid rim consists of loose connective fibers in the upper part (above the equator of the glenoid) while the inferior part of the labrum attachment is an inelastic fibrous tissue. Since the glenoid labrum is involved in the stability of the gleno-humeral joint, pathological conditions of the labrum appear in case of instability. www.shoulder.com /labralfind_castagna.html   (1572 words)

Medcyclopaedia - Labrum The glenoid labrum is a cuff of fibrous and fibrocartilaginous tissue surrounding the glenoid cavity. One criterion for labral tear is the glenoid labrum ovoid mass GLOM or GLOM. Normally the labrum has a "rose thorn" appearance, but this may be lost if the limbus becomes folded on itself and lies within the acetabulum. www.medcyclopaedia.com /library/topics/volume_iii_1/l/LABRUM.aspx   (565 words)

Glenoid Labrum Tears, Part II This test was unusual compared to most other labrum tests in that it involved a muscle test, a change in arm position and the patient's response as the determination of whether a labrum tear or acromioclavicular injury was present. SLAP lesions (superior labrum anterior to posterior) are specific lesions of the labrum at its attachment with the biceps tendon at the superior anterior glenoid. It is suspected that sudden contraction of the biceps may lift the labrum off the glenoid and result in a tear. www.chiroweb.com /archives/16/26/21.html   (1248 words)

labrum or 4 suture anchors are used to re-attach the Labrum to the Glenoid. The LABRUM is a fibrocartilage ring around the bony cup (Glenoid) of the shoulder.

The Physician and Sportsmedicine: Injuries to the Glenoid Labrum The most common mechanisms of injury to the glenoid labrum in athletes and the general public are acute and chronic excessive traction and compression. SLAP lesions are injuries to the labrum that extend from anterior to the biceps tendon to posterior to the biceps tendon. SLAP lesions are either stable or unstable, depending on whether the majority of the superior labrum and the biceps tendon are firmly attached to the glenoid margin. www.physsportsmed.com /issues/1999/06_99/richards.htm   (2496 words)

UCSD Musculoskeletal Radiology The labrum consists of a rounded fibrous elevation of the bony glenoid rim. The normal antero-inferior labrum is a rounded fibrous elevation of the glenoid rim and the anterior band of the IGHL is intimately attached to the glenoid rim and labrum at the 4 o'clock position. The lesion is a superficial tear of the antero-inferior labrum with an adjacent articular cartilage injury. medicine.ucsd.edu /bonepit/Classifications/SLAP.htm   (2511 words)

The Department of Orthopaedic Surgery The labrum is a second kind of cartilage in the shoulder which is distinctly different from the articular cartilage. The labrum is a thick tissue or type of cartilage that is attached to the rim of the socket and essentially forms a bumper which deepens the socket and helps keep the ball in place. A third type of labrum tear is in the area where the biceps tendon attaches to the upper end of the socket. www.hopkinsmedicine.org /orthopedicsurgery/labrumtear.html   (2001 words)

Labrum definition - Medical Dictionary definitions of popular medical terms The glenoid labrum is a ring of fibrocartilage that runs around the cavity of the scapula (wingbone) in which the head of the humerus (the bone in the upper arm) fits. Signs and symptoms of a glenoid labrum injury include pain accompanying overhead arm motion, occasional pain in the shoulder at night or during daily activities, decreased range of motion and loss of strength in the shoulder. Labrum was borrowed from the Latin for lip. www.medterms.com /script/main/art.asp?articlekey=18656   (309 words)

Baseball's most fearsome injury. - By Will Carroll - Slate Magazine The labrum is a thin matrix of collagen seated between the head of the humerus (bone of the upper arm) and the glenoid fossa (the shallow depression where the humerus fits). Labrum tears also show up irregularly on the football field—the Raiders' Rich Gannon (throwing shoulder) and the Seahawks' Matt Hasselbeck (non-throwing shoulder) are part of the labrum brigade—usually when a quarterback's arm gets planted into the ground at an unnatural angle. Unlike the rotator cuff, a series of four small muscles that holds the shoulder in place and decelerates the arm, the collagen-based labrum can't be strengthened. www.slate.com /id/2100895   (1568 words)

Acetabular Labrum Tears It has only been during the past decade that acetabular labrum tears have been recognized as a cause of groin pain, but a recent study found that in more than 20 percent of athletes presenting with groin pain, these tears were present. The acetabular labrum deepens the hip socket, as does the glenoid labrum for the shoulder, but the hip socket is much deeper than the shoulder and probably does not depend on the labrum as a choke block, as does the shoulder. It is thought that the labrum may enhance hip stability by providing negative intra-articular pressure during hip distraction by partially sealing the hip joint. www.chiroweb.com /archives/23/09/10.html   (740 words)

Acetabular labrum definition - Medical Dictionary definitions of popular medical terms Injuries to the acetabular labrum can occur from chronic trauma due to repetitive hip motion or from acute trauma as, for example, from a direct blow to the hip or a violent motion of the hip. Signs and symptoms of a acetabular labrum injury include pain accompanying hip motion, occasional pain in the hip at night or during daily activities, decreased range of motion and loss of strength in the hip. In medicine, a labrum is a ring of fibrocartilage around the edge of the articular (joint) surface of a bone. www.medterms.com /script/main/art.asp?articlekey=18659   (231 words)

SLAP Lesion The shoulder joint is formed by the humerus (upper arm) and the glenoid labrum of the scapula (shoulder blade). The biceps and labrum are becoming detached from their bed on the glenoid fossa. This injury is treated by “tacking” the labrum and biceps complex down to the glenoid with biodegradable suture anchors. www.athleticadvisor.com /Injuries/UE/Shoulder/slap_lesion.htm   (752 words)

acetabular labrum tears The labrum is a fibrocartilaginous rim which encompasses the circumference of the acetabulum – the socket on each side of the hip bone, into which the femur fits. The labrum, which effectively deepens the socket, is thought to enhance the stability of the hip joint and help distribute applied force more evenly across the surface of the cartilage. Acetabular labrum tear is a common finding in the aging adult hip and is also associated with traumatic injury, usually caused by the hip joint being stressed in rotation. www.pponline.co.uk /encyc/acetabular-labrum-tears.html   (506 words)

HSS - Shoulder Joint Tear (Glenoid Labrum Tear)   (Site not responding. Last check: 2007-10-08) The shoulder joint involves three bones: the shoulder blade (scapula), the collarbone (clavicle) and the upper arm bone (humerus). Because the head of the upper arm bone is usually much larger than the socket, a soft fibrous tissue rim called the labrum surrounds the socket to help stabilize the joint. A SLAP lesion (superior labrum, anterior [front] to posterior [back]) is a tear of the rim above the middle of the socket that may also involve the biceps tendon. www.hss.edu /Conditions/Glenoid-Labrum-Tear/Shoulder-Joint-Tear   (709 words)

Dr. Gartsman, Labrum Repair The labrum is a ring of soft fibrous tissue that surrounds the glenoid (the end of the shoulder blade) and helps stabilize the shoulder joint. Ligaments and tendons can attach to the labrum and when the labrum is torn, the shoulder becomes painful. This surgery is performed using an arthroscope to repair the torn labrum in your shoulder. www.drgartsman.com /labrum_repair   (701 words)
