  • Introduction
    . The ACS helps to prevent excessive superior translation of the shoulder. The supraspinatus, infraspinatus, teres minor, and subscapularis muscles comprise the rotator cuff (see the following image) (see Table 1, below). Philadelphia, Pa: WB Saunders; 1998. [8] Such deformities include cosmetic concerns (eg, a lump in the back and the appearance of a short neck). NEWEST MODULES: Inguinal Canal | Renal Physiology in Pregnancy | Abdominal Wall | Fetal Circulation | Neuroendocrine. CLINICAL ANATOMY. The shoulder is a complex joint, with a wide range of motion and functional demands. It facilitates normal movement and is also commonly involved in shoulder disorders. The acromioclavicular (AC) joint is the only articulation between the clavicle and scapula. The shoulder complex is composed of many different tissue types, and it is the connective tissue that provides the supportive framework for the shoulder's many functions. Choose from 500 different sets of clinical kinesiology and anatomy shoulder girdle flashcards on Quizlet. ANATOMY OF SHOULDER JOINT. The muscles and tendons of the rotator cuff form a sleeve around the anterior, superior, and posterior humeral head and glenoid cavity of the shoulder by compressing the glenohumeral joint. Here is the very basic anatomy of the shoulder joint (aka glenohumeral joint) showing the ball and socket joint where the humerus bone of the arm meets the scapula. Search. Upper limb.

Furthermore, the clavicle provides protection for the subclavian artery, subclavian vein, and brachial plexus posteriorly and inferiorly. Eur J Radiol. However, clavicle fractures are very common and account for 5% of all fractures in adults. Many people with shoulder pain, weakness, and instability often need to focus on improvements in their scapular function to help improve their shoulder mechanics. Clavicle fractures can be categorized into the following 3 groups, as classified by Allman [8] An anterior dislocation is likely to occur when the arm is abducted, extended, and externally rotated. The glenohumeral joint is the main articulation of the shoulder joint. https://profreg.medscape.com/px/getpracticeprofile.do?method=getProfessionalProfile&urlCache=aHR0cHM6Ly9lbWVkaWNpbmUubWVkc2NhcGUuY29tL2FydGljbGUvMTg5OTIxMS1vdmVydmlldw==, Table 1. Most joints allow for mobility, although several are fixed in their position. 3 • The articular surfaces are covered by hyaline cartilage. 338-45, 643-9, 759-63. Satvik Munshi, MD Instructor, Department of Physical Medicine and Rehabilitation, Louisiana State University Health Sciences Center Acute shoulder injuries. UBC Anatomy Labs. The capsule separates the joint from the rest of the body and contains the joint fluid. This wide range of motion also makes the shoulder joint unstable. Labral tears in the shoulder can cause pain, instability of the joint, or both. This rim of fibrocartilage is the glenoid labrum. Could Your Shoulder Pain Actually Be Arthritis? Procedures, 2002 These are the supraspinatus, infraspinatus, teres minor, and subscapularis (see the following image).

Studies have concluded that the coracoclavicular ligaments are the primary restraint to superior and posterior clavicular dislocation. 109130-overview Introduce yourself to the patient including your name and role. UpToDate. Shoulder motion requires the coordinated effort of muscles, tendons, ligaments, and bones primarily across the glenohumeral joint and scapulothoracic articulation (1). Thank you, {{form.email}}, for signing up. Violent muscle contractions during a seizure or electrocution may also produce a posterior glenohumeral dislocation. Primary adhesive capsulitis causes a painful and stiff shoulder usually without a known inciting event. Joints are stabilized by ligaments and cartilage. When the rotator cuff is inflamed or irritated, this is referred to as rotator cuff tendonitis or shoulder bursitis. This website also contains material copyrighted by 3rd parties. This is usually a condition that develops as people age and their articular cartilage wears down. If you log out, you will be required to enter your username and password the next time you visit. This has a rather shallow surface, which is directed anterolaterally and slightly cranially tilted. Focusing on the clinical anatomy of the radio-humeral joint we use this case to review the lateral approach to an intraarticular elbow injection. [8]. •Superiorly shoulder joint protected by supraspinatus. Anatomy, 2002 Posterior dislocation of the glenohumeral joint is rare but is more likely to occur when the arm is adducted and internally (medially) rotated. The subacromial bursa (SAB) is the main bursa of the shoulder. Lower Limb.

However the socket of the glenoid cavity of the scapula is itself quite shallow and is made deeper by the addition of the glenoid labrum. People with a rotator cuff tear may experience pain and weakness in their shoulder. It results from a direct blow to, or a fall on, an outstretched arm. 2 ARTICULATION Articulation is between: • The rounded head of the humerus and • The shallow, pear-shaped glenoid cavity of the scapula. Orthop Trans. Where the rounded top of the arm bone (humerus) contacts the shoulder blade is called the glenohumeral joint. This is called the acromioclavicular joint. The glenoid is covered with smooth cartilage. The force causes the acromion to suddenly move inferiorly, which first strains or tears the AC ligaments and may subsequently strain or tear the coracoclavicular ligaments as well. [1] This mobility provides the upper extremity with tremendous range of motion such as adduction, abduction, flexion, extension, internal rotation, external rotation, and 360° circumduction in the sagittal plane. There exist many articulations, unique s … Rockwood C, Matsen F, eds. The AC joint is an encapsulated diarthrodial joint held together by its joint capsule and the coracoclavicular ligaments: the trapezoid and conoid ligaments. Available at http://www.uptodate.com/contents/topic.do?topicKey=EM/238. Fractures of the anatomic neck of the humeral head are quite rare and have a poor prognosis, because the fracture usually disrupts blood supply to the humeral head. The glenoid cavity (or, alternatively, the glenoid fossa) is set on the expanded aspect of the lateral angle of the scapula. The proximal articular surface of the humerus is termed the humeral head. The shoulder capsule surrounds the ball-and-socket part of the shoulder joint. Gartner LP, Hiatt JL. Human Anatomy. … An understanding of the intricate network of bony, ligamentous, muscular, and neurovascular anatomy is required in order to properly identify and diagnose shoulder pathology. The pathophysiology associated with primary (idiopathic) frozen shoulder: A systematic review. The glenoid labrum is a ring of cartilaginous fibre attached to the circumference of the cavity. These variations are not considered pathologic. 59-60, 89-90. [7] The glenoid labrum, a fibrocartilaginous ring attached to the outer rim of the glenoid cavity, provides additional depth and stability. A second joint in the shoulder is the junction of the collar bone with the shoulder blade, called the acromioclavicular joint. The clavicle is an S-shaped bone that forms the anterior portion of the shoulder girdle that keeps the arm away from the trunk, allowing it to move freely. The acromioclavicular system (ACS) is formed by a complex of ligaments (conoid, trapezoid and acromioclavicular capsular ligaments) that stabilize the acromioclavicular joint (Fig. The shoulder or pectoral girdle is composed of the bones that connect the upper extremity to the axial skeleton.

(See also Multidirectional Glenohumeral Instability, Anterior Glenohumeral Instability, Posterior Glenohumeral Instability.). •Posteriorly shoulder joint protected by teres minor and infraspinatus. Two joints are at the shoulder. The AC joint is frequently injured in athletes. When the shoulder dislocates, the ligaments of the shoulder capsule can be torn. Philadelphia, Pa: Lippincott Williams & Wilkins; 2000. The human shoulder is the most mobile joint in the body. •Anteriorly shoulder joint protected by subscapularis. 49(4):774-84. [10]. 3. Like most synovial joints, the articulating surfaces are covered with hyaline cartilage. The Glenohumeral Joint (Shoulder joint) is a synovial ball and socket articulation between the head of the humerus and the glenoid cavity of the scapula.Glenohumeral joint is multiaxial with a broad range of movements provided in the cost of skeletal stability. 7th ed. When the shoulder capsule is too tight, the condition is called a frozen shoulder (adhesvie capsulitis).. The shoulder joint is markedly swells, shoulder becomes rounded, smoothed all bony prominences. The subacromial bursa lies on the superior aspect of the supraspinatus tendon (see the images below). If the capsule is too loose, the condition is called multidirectional instability. [9]. The shoulder joint is a ball and socket joint between the scapula and the humerus. 2002 All material on this website is protected by copyright, Copyright © 1994-2020 by WebMD LLC. One muscle group that is commonly implicated in people who have shoulder joint problems are the periscapular muscles. A labral tear may be asymptomatic or manifest as shoulder instability, pain, or crepitus. Jonathan Cluett, MD, is board-certified in orthopedic surgery. [2, 3, 4, 5, 6].

The glenoid cavity depth is increased by a rim of fibrocartilage that surrounds it. Table 1. Quillen DM, Wuchner M, Hatch RL. The biomechanical function of this ligament is not fully understood; however, it appears to have suspensory function of the humeral head. The glenohumeral, or shoulder, joint is a synovial joint that attaches the upper limb to the axial skeleton. Anterior shoulder dislocation. Introduction; Mental Status; Clinical Syndromes; Hands; Nails; Clubbing; Face; Mouth; Head & Neck. The scapula is a triangular-shaped bone that functions mainly as a site for muscle attachment. The Shoulder. It is approximately one-quarter the size of the humeral head and this, plus its shallow concavity, makes the joint both very mobile and vulnerable to (sub)luxations. C onse- quently, they are susceptibleto injury and de- generation. The head of the humerus usually tears the inferior part of the joint capsule and the patient maintains the limb in a laterally rotated and slightly abducted position. ABOUT US. Skip to content. Prev Next The shoulder is one of the largest and most complex joints in the body. The stiff glenohumeral joint is most likely a result of chronic inflammation and fibrosis. 1.7). The scapula has 4 processes, the spine, the acromion, the coracoid, and the glenoid. ), Sprengel deformity is a congenital deformity; this is actually a composite of deformities caused by an undescended, hypoplastic scapula. The 3 phases are as follows: "Freezing phase": Spontaneous pain and stiffness in the shoulder, "Frozen phase": Increased stiffness and stable or decreased pain, "Thawing phase": Increased range of motion and decreased pain. The articulations between the bones make up the shoulder joints. [1] This instability is compensated for by rotator cuff muscles, tendons, ligaments, and the glenoid labrum. 2016;17(1):340. doi:10.1186/s12891-016-1190-9, Ⓒ 2020 About, Inc.

The clavicle plays a significant role in shoulder stability, strength, and range of motion. Procedures, 2002 Anatomical Illustrations. The injury may be result of chronic impingement and tendonitis that has progressed, or it may refer to an acute injury such as a fall or direct trauma. These variations may range from an almost straight bone to one with exaggerated curves. Pelvis. Little motion exists in this joint. The joint capsule is a soft tissue envelope that encircles the glenohumeral joint and attaches to the scapula, humerus, and head of the biceps.It is lined by a thin, smooth synovial membrane. He served as assistant team physician to Chivas USA (Major League Soccer) and the United States men's and women's national soccer teams. T he joints of the shoulder com plex have to rely on adjacent ligam ents and m uscles to provide stability. Anatomy and Biomechanics: The glenohumeral joint provides the largest range of motion among all diarthrodial joints but also has the greatest propensity for instability. Clinical Anatomy of the Shoulder Book Description : This book provides detailed information on functional anatomy, physical examination, and clinical radiology of the shoulder with a view to enabling the clinician to identify the most suitable treatment approach to different shoulder joint pathologies. The glenohumeral joint is a multiaxial synovial ball and socket joint that functions as a diarthrosis to facilitate a wide range of motion for the upper extremity (2). The rotator cuff is a group of four muscles and tendons that surround the glenohumeral joint. The IGHL originates from the labrum and the adjacent glenoid neck, inserts on the anatomic neck of the humerus, and resists humeral head anterior and posterior translation. Click below and just hit send! Accessed: October 2010. Bigliani et al separated acromions into 3 categories based on their shape and their correlation with rotator cuff tears (see the image below), as follows: Type I: Flat undersurface of the acromion (This type has the lowest risk for impingement syndrome. Swelling of the shoulder joint may be visible due to a joint effusion, or synovial thickening.

What Happens When You Have a Torn Rotator Cuff? This gives rise to the alternate name for the shoulder joint – the glenohumeral joint. Back & Core. DENNIS L. HART, MPA, PTt The shoulder complex consists of several ana­ tomical joints and one physiological joint. In turn, the whole shoulder joint is covered by the three portions of the deltoid muscle. •Inferior aspect of shoulder joint completely unprotected. The labrum also serves as the attachment of a major tendon in the shoulder, the biceps tendon. The scapulothoracic joint is the physiological, or func­ tional, jOint between the underside of the scapula and the dorsal thoracic wall. Some of these other muscles are also critical to normal shoulder function. Patients usually present rotator cuff tendinopathy, frozen shoulder, axillary neuropathy and suprascapular neuropathy. An image depicting shoulder anatomy can be seen below. Please confirm that you would like to log out of Medscape. These are the clavicle and scapula. ), Type II: Curved undersurface of the acromion, Type III: Hooked undersurface of the acromion (This type has the highest correlation with subacromial pathology. The scapular notch varies in size and shape. The glenohumeral joint has six degrees of freedom of motion, which can be described by three rotations and three translations with respect to the anatomic coordinate system. The structures involved in tendinopathy and frozen shoulder can be easily identified and demonstrated under normal conditions. The scapula is freely moveable, because it is suspended by these muscles. Different Bones of Your Shoulder Can Be Fractured, The pathophysiology associated with primary (idiopathic) frozen shoulder: A systematic review. Several ligaments make up parts of the joint capsule, and these ligaments are important in keeping the shoulder joint in proper position. The sternoclavicular joint allows 30-35 º of upward elevation, 35 º of anteroposterior movement, and 44-50 º of rotation about the long axis of the clavicle. Three glenohumeral ligaments exist: (1) the superior glenohumeral ligament (SGHL), (2) the middle glenohumeral ligament (MGHL), and (3) the inferior glenohumeral ligament (IGHL). The injury commonly occurs when direct force is applied to the acromion with the arm adducted.
