Glenohumeral Joint - SlideShar

Anatomy. The shoulder is a synovial articulation between the glenoid and the humeral head in which the shallow glenoid articulation is deepened an additional 50% by the fibrocartilaginous labrum that forms a rim around the perimeter of the glenoid ().Both the glenoid and the humeral head are covered by a layer of hyaline articular cartilage Anatomy of shoulder joint to help pain interventionists during procedure Labral Tear. Shoulder instability can occur whenever the labrum is torn or peeled off of the glenoid. This can occur after a shoulder dislocation, shoulder trauma or as a result of repetitive motion (like throwing a baseball). Genetic Condition.

  1. The glenoid labrum is routinely evaluated in all three imaging planes. Although the axial plane is usually emphasized as best for labral evaluation, several authors have found the coronal plane most sensitive in the diagnosis of SLAP lesions . The superior labrum is situated in a more curved area of the glenoid bone and therefore is more.
  2. Glenoid labrum. Patient position: Same as for infraspinatus and inferior to this for the more inferior part of the posterior labrum. For the anterior part, transverse as for biceps tendon, and for the more posterior part, hand behind the head with shoulder abducted. The literature claims high sensitivity and specificity, especially for the.

  4. Shoulder anatomy The shoulder joint (glenohumeral joint) is a ball and socket joint between the scapula and the humerus.It is the major joint connecting the upper limb to the trunk. It is one of the most mobile joints in the human body, at the cost of joint stability. Joint Capsule and Bursae The joint capsule is a fibrous sheath which encloses the structures of th
  5. The Glenoid Labrum is a rubbery fibrocartilaginous structure that lines the shoulder joint to provide more surface area for the head of the humerus and the glenoid fossa of the scapula. As you can see, the labrum is like a washer between the 2 bones and acts to limit motion of one bone on the other. The labrum also acts as a shock absorber as.

  2. Background: All-soft tissue suture anchors provide advantages of decreased removal of bone and decreased glenoid volume occupied compared with traditional tap or screw-in suture anchors. Previous published data have led to biomechanical concerns with the use of first-generation all-soft suture anchors. Purpose/hypothesis: The purpose of this study was to evaluate the load to 2-mm displacement.
  3. The fairly flat socket of the glenoid surrounds only 20% - 30% of the humeral head. Because of its poor fit, this joint relies heavily on the surrounding soft tissue for support. The labrum, a ring of fibrocartilage tissue, attaches to the glenoid and deepens the socket to encircle more of the humerus

Medially to the margin of the glenoid cavity outside the labrum; Laterally to the anatomic neck of the humerus. • The capsule is thin and lax, allowing a wide range of movement. 6 LIGAMENTS 1. The glenohumeral ligaments are three weak bands of fibrous tissue that strengthen the front of the capsule. 2 The glenohumeral joint capsule consists of a fibrous capsule, ligaments and the glenoid labrum. Because of its lack of bony stability, the glenohumeral joint is the most commonly dislocated major. At the glenohumeral joint, this injury can result in a tear of the glenoid labrum known as a soft Bankart. In theses lesions, the anteroinferior part of the glenoid labrum is torn in an anterior shoulder dislocation. It therefore stands to reason that a reverse soft Bankart would affect the posteroinferior glenoid labrum in a posterior shoulder. The glenoid labrum (Fig. 6) typically is described as a substantial structure of fibrocartilage that at­taches to the periphery of the glenoid and is wedge­shaped in cross-section. It both continues the general contour of the glenoid and increases the surface area of the articular surface

Anterior release or surprise test (anterior glenohumeral instability) Purpose: To detect an occult anterior instability of the shoulder joint (1). Patient position: Supine lying with the affected shoulder over the edge of the examination table. Examiner position: Stand facing the patient's affected side Glenoid Labrum [edit | edit source] The Glenoid labrum is a fibrocartilaginous, ridge-like connective tissue which increases articular surface area for the humeral head by deepening the glenoid fossa. It provides the primary attachment for the glenohumeral ligaments and gives rise to the long head biceps tendon, capsule, and scapular neck

  3. glenoid labrum, capsule, capsular lig- aments, and bony articulation. The humeral head is approximately three times the radius of the glenoid fossa, and this anatomical relationship lends to the intrinsic instability of glenohumeral joint. Dynamically, the glenoid must follow the movement of the humeral head to maintain it
  4. ology and classifications used when describing shoulder instability. When a shoulder is unstable it can dislocate, this is the complete separation of the ball of the shoulder, called the head of the Humerus (HOH) from the socket, called the Glenoid.An unstable shoulder can also sublux, this is slightly different from a dislocation in that its a partial.

The labrum is a rim of cartilage that surrounds the socket of the shoulder joint. The socket of the shoulder joint is shallow, and the labrum gives the socket more depth, and thus more stability. The labrum also serves as the attachment of a major tendon in the shoulder, the biceps tendon

The glenoid is a saucer-shaped extension of the scapula. Its shape means that it offers limited bony support to the joint. The glenoid is augmented by the cartilaginous labrum with additional support from the joint capsule, surrounding ligaments and the muscles of the rotator cuff In the knee, chondromalacia is usually related to injury, overuse of the knee, and poorly aligned muscles and bones around the knee joint. These causes include: An imbalance of the muscles around the knee (Some muscles are weaker than others.) Overuse (repeated bending or twisting) of the knee joint, especially during sports The glenoid labrum is a ring composed of mostly dense fibrous tissue. The average depth of the glenoid cavity is 2.5 mm, but the labrum serves to increase this depth. Although the labrum increases the depth and volume of the glenoid cavity, it does not seem to increase the stability of the glenohumeral joint

Joint Capsule and Bursae. The joint capsule is a fibrous sheath which encloses the structures of the joint.. It extends from the anatomical neck of the humerus to the border or 'rim' of the glenoid fossa.The joint capsule is lax, permitting greater mobility (particularly abduction). The synovial membrane lines the inner surface of the joint capsule, and produces synovial fluid to reduce. Glenoid labrum injury: Pain with abduction/external rotation (anterior labrum), adduction or loading (posterior labrum), or overhead activity (superior labrum) Glenohumeral instability or apprehension with certain arm positions: Absence of neurologic symptoms: Neck pain is infrequent Symptoms maximal when in an at-risk position for the. Humeral head articulates with the glenoid cavity. The cavity is deepened by the glenoid labrum. About 1/3rd of the head actually sits in the cavity. Articular capsule Attaches proximally to the margins of the glenoid cavity, and distally to the anatomical neck of the humerus. IT HAS HOLES IN IT. One hole admits the tendon of the long head of bicep A ring of cartilage called the labrum surrounds the glenoid, while articular (smooth) cartilage covers the head of the humerus. In an anatomic total shoulder replacement, the humeral head and articular cartilage is replaced with a metal ball, and the glenoid is fitted with a plastic piece Examine the glenoid margin and the humeral head for defects. The distal stump of the subscapularis tendon is attached to the most convenient soft-tissue structure along the anterior rim of the glenoid cavity, which may be the labrum itself

Shoulder joint dislocation is often seen with glenohumeral joint. Shoulder joint separation is either partial or complete. Partial separation is known as subluxation and complete separation is known as dislocation. Dislocation is a breakage of link between humerus and glenoid socket of scapula Introduction [edit | edit source]. Internal impingement is a common cause of shoulder pain in overhead athletes. It is commonly described as a condition characterized by excessive or repetitive contact between the posterior aspect of the greater tuberosity of the humeral head and the posterior-superior aspect of the glenoid border when the arm is placed in extreme ranges of abduction and. 10.1055/b-0039-167677 28 Eden-Hybinette for Failed Latarjet ProcedureKyong S. Min, Neal C. Chen, Michelle J. Chang, and Jon J.P. Warner Abstract The Eden-Hybinette procedure is an option for treatment in patients with glenohumeral bone loss greater than 40% of the glenoid. Iliac crest bone graft is fashioned and secured to the glenoid defect therapist. Glenoid labral pathology was evident on prior magnetic resonance imaging, which had led to a persistent focus on the shoulder. The evalua-tion by the physical therapist revealed significant mobility deficits in the cervical, thoracic, and lum-bar spine. Radiographs and laboratory tests were ordered and a referral was made to rheumatolog A shoulder dislocation may look visibly deformed, however. The ball has separated completely from the socket, so the shoulder may square off and look like it is at an odd angle. Oftentimes, there may be an associated fracture with the dislocation.With a shoulder subluxation, you may notice a bump at the top of the shoulder

The glenoid fossa is deepened by the glenoid labrum (a ring of cartilage), which also provides a suction effect for the joint. The glenohumeral joint is a highly mobile joint, but is unstable as a result. Although the glenohumeral joint is a ball and socket joint, the glenoid fossa (the socket) is shallow like a dish Abstract. Instability of the glenohumeral joint is a common cause of chronic shoulder pain and disability. One or more episodes of subluxation or dislocation may result in a tear, detachment, or attenuation of the glenoid labrum, stripping of the joint capsule from the scapula, or trauma to the tendons or muscles of the rotator cuff supraspinatus is 12.7mm (covers superior facet of greater tuberosity) 6-7 mm tear corresponds to 50% partial thickness tear. infraspinatus is 13.4mm. subscapularis is 17.9mm. teres minor is 13.9mm. distance between articular cartilage to medial footprint of rotator cuff is 1.6-1.9 mm.

US of amyloid infiltration shows subchondral bone erosions with well-defined margins, containing hypoechoic amyloid, joint effusion, juxtaarticular soft-tissue amyloid masses with thickening of the synovium, and chondrocalcinosis of the glenoid labrum and humeral head cartilage due to renal osteodystrophy (, 2 28 32) (, Figs 61- 63) The glenoid labrum is the fibro-cartilage ring attached to the rim of the glenoid cavity, and acts to stabilize the humeral head inside the glenoid. The Bankart (slideshare.net) The clavicle, coracoid , and scapula on each side form a bony articulation at the glenoid fossa Biceps tenodesis involves cutting the biceps tendon off the labrum, which is the pad of cartilage inside the glenoid, and reattaching it to the humerus (upper arm bone). Biceps tenotomy means cutting off one tendon and not reattaching it, allowing it to heal to the humerus over a few weeks The socket of the glenoid is surrounded by a soft-tissue rim (labrum). A smooth, durable surface (articular cartilage) on the head of the arm bone and socket, a thin inner lining (synovium) of the joint allows the smooth motion of the shoulder joint Scapular dyskinesis is an alteration in the normal position or motion of the scapula during coupled scapulohumeral movements.It occurs in a large number of injuries involving the shoulder joint and often is caused by injuries that result in the inhibition or disorganization of activation patterns in scapular stabilizing muscles. It may increase the functional deficit associated with shoulder.

Labrum. The glenoid labrum enhances stability by substantially increasing the depth, height, and width of the glenoid. Suture anchors provide multiple points of fixation from which capsulolabral tissue can be reconstructed back up onto the surface of the glenoid rim during a stabilization procedure The images through the glenoid labrum show intact superior and inferior lips. The anterior and posterior lips of the glenoid labrum also appear intact. No indication of any subluxation of the biceps tendon. IMPRESSION: Complete tear of the rotator cuff with retraction of the supraspinatus muscle and tendon component. Slight high-riding position.

The scapula, or shoulder blade, is a large triangular-shaped bone that lies in the upper back. The bone is surrounded and supported by a complex system of muscles that work together to help you move your arm. If an injury or condition causes these muscles to become weak or imbalanced, it can alter the position of the scapula at rest or in motion The labrum is a rim of cartilage that surrounds the socket of the shoulder joint. The attachments of the muscles to the scapula are noted in Figure 4.4 . Both the glenoid and the humeral head are covered by a layer of hyaline articular cartilage. When indicated, the axilla should be evaluated for masses, lymph nodes, and palpation of the muscles recommended to first assess the labrum and biceps tendon. Arthroscopy = marked hemorrhage & edema in the glenohumeral joint (Figure 2). A: The extensive injury to the rotator cuff was confirmed, as was instability of the biceps tendon.

When we perform flexion, the glenohumeral (GH) joint contributes 100°-120°. The scapula on the thorax contributes to elevation (flexion and abduction) of the humerus by upwardly rotating the glenoid fossa 50° to 60° from its resting position. If the humerus were fixed to the fossa, this alone would result in up to 60° of elevation of the.
