Shoulder Anatomy This is an axial T1 MRI image at the top of the shoulder. The Shoulder Joint is considered as a 'ball and socket' joint. Between the meeting point of these bones lies the labrum – a band of fibrocartilaginous tissue that helps to nest the ball of the upper arm bone within the shallow socket formed by the glenoid. In order to understand how injuries in our shoulder occur, we first have to understand the anatomy. It reinforce s and stabilizes the shoulder joint and cushions the bones and ligaments attached to it. The shoulder consists of the clavicle, scapula, and humeral head. It consists of the labrum (a type of fibrocartilage tissue) which supports in forming a suction cup for the humerus (arm bone), thus leading to stability and improved mobility of the joint. The shoulder complex is made up of three bones, which are connected by muscles, ligaments, and tendons. Anatomy. ANATOMY OF SHOULDER JOINT.

Labrum tears can also result from a traumatic event, like a fall, and with age due to wear and tear. The shoulder joint can be categorized as a ball and socket joint. The Glenoid Labrum (Glenoid Ligament) is a fibrocartilaginous rim attached around the margin of the Glenoid cavity in the Shoulder Blade. However, in bony terms the 'socket' (the glenoid fossa of the Scapula) is quite shallow and small, covering only a third of the 'ball' (the head of the Humerus). WebMD's Shoulder Anatomy Page provides an image of the parts of the shoulder and describes its function, shoulder problems, and more. In particular the glenoid labrum (GL), the proximal attachment of the joint capsule and the lateral glenohumeral ligament, is an important passive stabilizer in the human shoulder. The anatomy of the glenohumeral joint in humans is characterized by static and dynamic stabilizing structures. All structures look dark because of fat suppression. However, in bony terms the 'socket' (the glenoid fossa of the scapula) is quite shallow and small, covering at most only a third of the 'ball' (the head of the humerus). At full term (40weeks and 370mm CRL), the labrum forms a well defined ring, deepening the concavity of the glenoid fossa. More specifically, superior labrum lesions about the insertion of the long biceps tendon were typically noted or managed using standard open surgical techniques. The ball is on the top of the upper arm bone and the socket is on the shoulder blade. The large bone in the upper arm is called the humerus. It covers the bones, ligaments, muscles and other structures that make up the shoulder. The shoulder is the most flexible joint in the body enabling a wide range of movements including, forward flexion, abduction, adduction, external rotation, internal rotation, and 360-degree circumduction. Crossref , Medline , … BASIC SHOULDER ANATOMY. The shoulder joint is considered a ball and socket joint. for more anatomy content please follow us and visit our website: www.anatomynote.com. The shoulder is one of the most sophisticated and complicated joints of the body: It has the greatest range of motion of any joint in the body allowing complete global movement allowing you to position the hand anywhere in space. Glenoid labrum variants Dr Balint Botz and Assoc Prof Frank Gaillard et al. The shoulder joint has three bones: the shoulder blade (scapula), the collarbone (clavicle), and the upper arm bone (humerus). 3 • The articular surfaces are covered by hyaline cartilage. Shoulder Anatomy. The labrum can tear a few different ways: 1) completely off the bone, 2) within or along the edge of the labrum, or 3) where the bicep tendon attaches. The coordinated activity of numerous muscles working together in set patterns is required to produce this motion. Our Team Online Consultations ... A firm, rubbery ring of tissue called the labrum is attached to the edge of the glenoid, and the humeral head and glenoid are covered in a smooth, gliding surface called articular cartilage (joint surface). Anatomy and function of the labrum. Radiol Clin North Am 2006 ;44(4):479–487, vii. The glenoid labrum (glenoid ligament) is a fibrocartilaginous rim attached around the margin of the glenoid cavity in the shoulder blade. 3 3 Human Anatomy Department, Faculty of Medicine, University of Zawia, Zawia, Libya. However, the socket is not a full cup, it is a shallow depression similar to a golf tee. The large bone in the upper arm is called the humerus. Some researchers believe it is a ‘normal’ variant, which is found infrequently in shoulders on MRI and routine shoulder arthroscopies. On first entry to the joint, the biceps tendon must be identified for orientation purposes. compare the labrum of the hip and shoulder. An improved understanding of the surgical anatomy … What is the anatomy of the glenoid labrum? The shoulder blade is called the scapula and collarbone is called the clavicle. Fat suppression is commonly used after contrast is given on MRI to increase the conspicuity of the contrast material as you will see on later images. The shoulder is a ball-and-socket joint between the upper arm bone, which is called the humerus, and the shoulder blade, which is called the scapula. The head of the upper arm bone (humeral head) rests in a shallow socket in the shoulder blade called the glenoid. The extraordinary range of the shoulder is due to the shallow osseous glenohumeral articulation. The shoulder complex (involving 4 joints, muscles and tendons, ligaments, labrum, capsule, bursa, and neuromuscular bundles), is among the most complicated regions of the body. It consists of four joints: sternoclavicular, acromioclavicular, scapulothoracic, and glenohumeral. CONTINUE SCROLLING FOR RELATED SLIDESHOW. We want to evaluate the similarities and differences, with special focus on its anatomy, general development, pathology and therapy. The posterior labrum is now more fibrocartilagenous and the whole of the labrumismorevascular. Ligaments bind the arm bone to the cup providing static stability. This injury is common among athletes participating in sports that involve repetitive throwing or overhead motions, such as baseball and volleyball, as well as football. The biceps tendon is visualised from the attachment known as the biceps anchor in the supraglenoid tubercle and superior labrum, along the rotator interval as far as the point where it emerges from the shoulder (Figs. This section is a review of basic shoulder anatomy. The labrum also serves as an attachment point for the long head of the biceps tendon, the glenohumeral ligaments, and the long head of the triceps tendon, forming a periarticular system of fibers that gives the shoulder joint much needed stability. 4 4 King Saud bin Abdulaziz University for Health Sciences, Riyadh, Saudi Arabia. Glenoid cavity. In this episode of eOrthopodTV, orthopaedic surgeon Randale C. Sechrest, MD narrates an animated tutorial on the basic anatomy of the shoulder. Arthritis Foundation: "Shoulder Anatomy." The term labrum is used in anatomy to designate a lip, edge, or brim. With this tool, they have been able to identify and treat a shoulder injury called a glenoid labrum tear. • The glenoid cavity is deepened by the presence of a fibrocartilaginous rim called the glenoid labrum. The shoulder is the most mobile joint in the body and undergoes a lot of wear and tear. The shoulder labrum is a thick piece of tissue attached to the rim of the shoulder socket that helps keep the ball of the joint in place. 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. 2 ARTICULATION Articulation is between: • The rounded head of the humerus and • The shallow, pear-shaped glenoid cavity of the scapula. Know more about the shoulder anatomy. Hopkins Medicine: "Shoulder Labrum Tear." CONCLUSION. Bankart lesion or labral tear ). The shoulder is a ball-and-socket joint composed of the upper head of the humerus (ball) and a pocket-shaped bone known as the glenoid (socket). This ball sits in a socket on the end of the scapula. Labrum: In medicine, a ring of fibrocartilage (fibrous cartilage) around the edge of the articular (joint) surface of a bone. Normal MR imaging anatomy of the rotator cuff tendons, glenoid fossa, labrum, and ligaments of the shoulder. The glenohumeral joint is a ball and socket joint which has sacrificed stability for mobility - stability is provided by a strong capsule, ligaments and surrounding musculature. We studied the gross, histological, and vascular anatomy of the glenoid labrum in twenty-three fresh-frozen shoulders from cadavera to demonstrate its cross-sectional anatomy, its microvascularity, and its attachments.
