SHOULDER COMPLEX ANATOMY Osseous Elements The shoulder complex includes the articulations of the humerus, the clavicle, the scapula, and the posterior surface of the ribs. The shoulder is made up of two joints, the acromioclavicular joint and the glenohumeral joint. Glenohumeral joint (Articulatio glenohumeralis) The glenohumeral, or shoulder, joint is a synovial joint that attaches the upper limb to the axial skeleton. When we talk about the human shoulder joint, it refers to the area of the body where the humerus (the long bone in the arm of humans extending from shoulder to the elbow) is attached to scapula. Let’s talk about some of the things that make this joint different both in skeletal structure and musculature from other joints less likely to be injured. Static stabilizers include the bony anatomy, negative intra-articular pressure, the glenoid labrum, and the glenohumeral ligaments along with the joint capsule. Fibers that connect bone to muscle are called tendons. They are shaped to move against each other with minimum friction. Fibrous sheaths that connect bone to bone are called ligaments. Joint Anatomy and Basic Biomechanics OUTLINE 3 From: Harmony Medical. The lever is one of the sim-plest of all mechanical devices that can be called a ma-chine.The relationship of fulcrum to force to resistance distinguishes the different classes of levers. Basic Shoulder Anatomy The shoulder complex is made up of three bones, which are connected by muscles, ... shoulder complex joints, the sternoclavicular, the acromioclavicular and the scapulothoracic joints. These are the clavicle and scapula. The dynamic-stabilizing structures include the rotator cuff muscles and the other muscular structures surrounding the shoulder joint. The shoulder girdle (composed of the scapula and clavicle) and pelvic girdle are the two points in the body where the axial and the appendicular skeletons meet. reviews the anatomy and physiology of bone. composed of a complex structure of bones, joints, and mus-cles, the foot is also our steady connection to the ground. Shoulder Anatomy : Anatomy of The Shoulder Joint External Rotation : The elbows are held by the sides of the body, bent at 9 with palms facing each other. 31 The Hip Joint The Lumbar Plexus .

The humerus is a long bone that forms the articulations of the glenohumeral joint proximally (with the scapula), and the humeral ulnar joint and humeral radial joint distally (with the ulna and radius respectively). In this article, we shall look at the anatomy of the shoulder joint and its important clinical correlations. The unique anatomy of the shoulder enables the greatest range of motion of any joint in the body. All rights reserved.

All decisions about Arthroscopy must be made in conjunction with your surgeon or a licensed healthcare provider. Shoulder Anatomy. Anatomy. Shoulder Joints. Anatomy of The Shoulder Joint. The capsule of the glenohumeral (shoulder) joint is the articular capsule of the shoulder.It completely surrounds the joint. Nursing Times [online]; 116: 2, 38-42. The scapulothoracic joint is not a true joint but it describes movement of the scapula against the thoracic wall during arm movement. The socket of the shoulder joint is part of the scapula, and if scapular movement is not normal, then shoulder function cannot be normal. The shoulder joint is formed by the articulation of the head of the humerus with the glenoid cavity (or fossa) of the scapula. Next: Gross Anatomy. The acromioclavicular joint is where the acromion, part of the shoulder blade (scapula) and the collar bone (clavicle) meet. Osteology. Methods: It was reviewed a large number of recently published research studies related to the shoulder instability that received a higher Level of Evidence grade. Several structures hold the bones together. How skeletal structure lends to shoulder instability. The shoulder or pectoral girdle is composed of the bones that connect the upper extremity to the axial skeleton. Knee Joint Anatomy Torn Anterior Cruciate Ligament . The information in this presentation has been developed to help consumers understand the structure and function of anatomical components and take charge of Orthopedic health. Hinge Joints • HINGE JOINTS allow extensive flexion and extension (Bending and straightening) with only a small amount of rotation.

It involves articulation between the glenoid cavity of the scapula (shoulder blade) and the head of the humerus (upper arm bone). 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. Commonly thought of as a single joint, the shoulder is actually made up of two separate joints - the glenohumeral and acromioclavicular joints. This flexibility is also what makes the shoulder prone to instability and injury. Citation Walker J (2020) Skeletal system 1: the anatomy and physiology of bones. View Media Gallery. The shoulder joint (or glenohumeral joint from Greek glene, eyeball, + -oid, 'form of', + Latin humerus, shoulder) is structurally classified as a synovial ball and socket joint and functionally as a diarthrosis and multiaxial joint. applied by muscles at some point along the lever to move the body part (resistance). humeral (shoulder joint), sternoclavicular, acromio-clavicular, and scapulothoracic joints. 29 Anatomy of the Nose Etiology of Pressure Sores . An image depicting shoulder anatomy can be seen below. The shoulder muscles are responsible for maintaining the widest range of motion of any joint in your body. Structures of the Shoulder Joint Articulating Surfaces. In this chapter only those muscles that are not discussed else-where are described. • b) Glenohumeral ligament –extend from the edge of glenoid cavity to lesser tubercle of humerus • c) Transverse humeral ligament –runs between the lesser and the greater tubercles. The shoulder is the most flexible joint in your body, and given the number of everyday activities it's involved in—from brushing your hair to reaching up into the cupboard—it's easy to see why shoulder pain is something you'd want to get to the bottom of right away.

C onse- quently, they are susceptibleto injury and de- generation. The glenohumeral joint is where the ball (humeral head) and the socket (the glenoid) meet. Prev Next The shoulder is one of the largest and most complex joints in the body. It is attached above to the circumference of the glenoid cavity beyond the glenoidal labrum, and below to the anatomical neck of the humerus, approaching nearer to the articular cartilage above than in the rest of its extent. 1 ©McGraw-Hill Higher Education.
