If you remember back to the start of this blog, I mentioned the shoulder joint is a “ball & socket” joint. It is a multiaxial joint (3O freedom of movement) e.g. is held against the socket rather than fitting into it. The shoulder is a complex joint that has great mobility. Hip Joint The hip joint, like the shoulder, is a ball and socket joint with very good movements but not to the same range as the shoulder joint. The Glenohumeral or the real shoulder joint is made up of the articulation of the ball of the head of the arm bone called the humerus into the cup of the shoulder blade called the scapula. In the tip of the shoulder, there is bony prominence, it is an acromion process. In order to understand shoulder impingement you need to be familiar with the basic anatomy of the shoulder: The shoulder is a ball and socket joint made up of three bones: the upper arm (humerus), the shoulder blade (scapula) and the collarbone (clavicle). It corrects the shoulder sub-luxation and its medial rotation, through its optimised traction and intimate fit. The best analogy I can think of is that it acts like a suction cup to help keep the shoulder joint stable. Additionally, the image can provide information on the position of the shoulder joint, any bone abnormalities (including bone tumors) and soft tissue disorders (think of calcifications in the rotator cuff muscles). It permits a lot of movement. A layer of cartilage called the labrum cushions and deepens the socket. The articulatio humero-scapularis (shoulder joint) is one of the ball and socket joints. This new prosthesis reverses the normal ball-and-socket relationship of the shoulder joint. , Professor , UW Orthopaedics & Sports Medicine A dislocated shoulder is an injury in which your upper arm bone pops out of the cup-shaped socket that's part of your shoulder blade.

A white, shiny, flexible band of fibrous tissue that holds joints together and connects various bones, including the following: Joint capsule. the joint by increasing the depth of the glenoid socket, enlarg-ing the surface area and acting as a load-bearing structure for the humeral head. subacromial bursa is present just below acromion process and above the ball and socket joint of the shoulder. Shoulder pain and problems are common. This joint has move movement than any other joint in the body, but when the shoulder becomes arthritic it can be a source of pain and disability. Frozen shoulder, or adhesive capsulitis, is a condition that begins with a gradual onset of pain and a limitation of shoulder motion.The discomfort and loss of movement can become so severe that even simple daily activities become difficult. Above the ball and socket joint there is a ligament attached to the bony prominences on the Shoulder osteoarthritis can be either primary or secondary. This can happen as a result of a sudden injury or from overuse. There are many tests for diagnosing shoulder impingement. This ability to move also increases the chances that it can be injured. Ligaments. Articular surface: The joint is formed by articulation of the scapula and the head of the humerus. Start studying Chapter 7 Shoulder Joint- Exam 2.

The shoulder complex, composed of the clavicle, scapula, and humerus, is an intricately designed combination of four joints, the Glenohumeral (GH) Joint, the Acromioclavicular (AC) Joint and the Sternoclavicular (SC) Joint, and a "floating joint", known as the Scapulothoracic (ST) joint.. The synovial membrane of the joint capsule is mainly . The socket of the shoulder is formed by part of the shoulder blade, and the ball of the shoulder joint is the top of the arm bone. Overview. The joint is formed by the articulation of the spherical head of the femur with the acetabulum or socket. When the back part of your shoulder becomes bound down it causes the shoulder joint to ride forward and up in the socket. The s capula is the proximal joint component, with a concave articulation surface due to its glenoid cavity, while its distal joint partner, the humeral head, is convex. Shoulder subluxation happens when the ball of the upper arm bone comes partly out of its socket. Joint disease - Joint disease - Congenital and hereditary abnormalities: Congenital abnormalities are not necessarily transmitted from generation to generation but can be acquired during fetal life or soon after delivery. The shoulder becomes swollen and warm to the touch. If there is chronic damage to the rotator cuff, the humeral head under the shoulder socket will be higher on the x-ray. Although much is known about this condition, there continues to be considerable controversy about its causes and the best ways to treat it. SHOULDER PAIN • The synovial membrane, capsule, and ligaments of the shoulder joint are innervated by the axillary nerve and the suprascapular nerve. Shoulder arthritis occurs when the cartilage starts wearing down on the ball and/or socket sides of the shoulder joint. Introduction. Shoulder impingement is a very common cause of shoulder pain, where a tendon (band of tissue) inside your shoulder rubs or catches on nearby tissue and bone as you lift your arm. Anatomy of the shoulder joint. The SC joint is the only bony attachment site of the upper extremity to the axial skeleton. It … Shoulder arthritis is a condition in which the normally smooth cartilage covering the ball and socket of the shoulder joint is lost due to disease wear and tear injury or surgical misadventure Edited By Frederick A. Matsen III, M.D. • The muscles surrounding the joint undergo reflex spasm in response to pain This all confirms the suspicion of arthrosis in the shoulder. • The joint is sensitive to pain, pressure, excessive traction, and distension. The shoulder is the body's most mobile joint, which makes it susceptible to dislocation. X-Shoulder Indication/Technique. Shoulder joint (glenohumeral joint). SHOULDER JOINT (GLENOHUMERAL JOINT) It is a synovial joint of the ball and socket variety. The GH, AC and SC joints link the upper extremity to the axial skeleton at the thorax. Shoulder dislocations can be partial, with the ball of the upper arm coming just partially out of the socket. Primary OA has no specific cause, but is related to age, genes and sex. Secondary adhesive capsulitis develops after an injury or surgery to the shoulder. The ball and socket joint (or spheroid joint) is a type of synovial joint in which the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone. The cup makes only 1/8th of the circumference of the shoulder and hence the shoulder joint is seemingly unstable, especially if compared to other large ball and socket joints of the body that is the hip joint. A shoulder replacement is used to minimise any pain that might be occurring secondary to any degenerative changes (arthritis) of the smooth surfaces of the ball and socket of the shoulder joint. A dislocation occurs when the humerus pops out of its socket… The ST joint involves the gliding movement of the scapula along the rib cage during upper extremity movements and does not include a physical bone-to-bone attachment. This is called a subluxation. The distal bone is capable of motion around an indefinite number of axes, which have one common center. It affects the rotator cuff tendon, which is the rubbery tissue that connects the muscles around your shoulder joint … A shoulder replacement can come in many different designs, and the appropriate implant will be chosen depending on the pattern or severity of your arthritis. Primary OA is usually seen in people over the age of 50, and women are affected more often than men. Shoulder instability occurs when the head of the upper arm bone is forced out of the shoulder socket.

The primary reason to make a shoulder x-ray is to confirm or exclude the presence of a fracture. Type: The shoulder joint (or glenohumeral joint from Greek glene, eyeball, + -oid, 'form of', + Latin humerus, shoulder) is a multiaxial synovial ball and socket joint. That wasn’t 100% accurate. This is usually the result of trauma or sports injuries, and it is also common after a stroke. The shoulder is a "ball-and-socket" joint where the "ball" is the rounded top of the arm bone (humerus) and the "socket" is the cup (glenoid) of the shoulder blade. This enables the joint … The labrum is a ring of fibrous tissue within the ball and socket of the shoulder joint that helps with the stability of the joint (see below). By using ultrasound exams and magnetic resonance imaging (MRI), our specialists can also precisely determine the extent of the defects in the tendon cuff and secondary inflammatory reactions. The shoulder joint is a ball and socket joint. A ball-and-socket joint that facilitates forward, circular, and backward movement of the shoulder. Symptoms of shoulder arthritis may include pain in the shoulder joint, stiffness and reduced range of motion. … The NEURO-LUX® II enables the repositioning of the humeral head in the shoulder socket reducing shoulder pain and preventing secondary damage to articular capsule, tendons, muscles or nerves and helps to prevent shoulder-hand syndrome. It thus depends on its surrounding structures and in particular the rotator cuff (a group of muscles and tendons that form a hood over the The shoulder joint or glenohumeral joint is a ball and socket joint but unlike the hip, the ball. Surface Anatomy of the Shoulder Joint. Joint replacement surgery: Also called arthroplasty, joint replacement of the shoulder involves replacing the parts of the shoulder damaged by arthritis with an artificial prosthetic joint. The shoulder joint is a ball-and-socket joint with a wide range of movement produced by part of the biceps muscle, several smaller muscles that make up the rotator cuff, various muscles in the chest wall, and the deltoid muscle (at the top of the upper arm and shoulder). It is formed from a ball on the top of your arm bone (humerus) and a shallow socket which is part of the shoulder blade (scapula). Abduction and adduction, circumduction, medial and lateral rotation making it a multiaxial joint. There are many types of shoulder problems that are caused by injuries and sudden (acute) or long-lasting (chronic) inflammation of the shoulder joint. There also may be reduction in synovial fluid, which normally helps the shoulder joint, a ball and socket joint, move by lubricating the gap between the humerus (upper arm bone) and the socket in the shoulder blade. As a result of re-placement of the glenoid component with a ball and of the humeral head with a socket, the center of rotation is moved distally and medi- Most commonly the sufferer complains of pain during overhead activity and reaching back pocket. The other (and more common form of shoulder injury in athletes in my experience) is secondary impingement. Picture a golf ball sat on a tee.
