It corrects the shoulder sub-luxation and its medial rotation, through its optimised traction and intimate fit. 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. The SC joint is the only bony attachment site of the upper extremity to the axial skeleton. A white, shiny, flexible band of fibrous tissue that holds joints together and connects various bones, including the following: Joint capsule. The distal bone is capable of motion around an indefinite number of axes, which have one common center. The other (and more common form of shoulder injury in athletes in my experience) is secondary impingement. 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- The shoulder is the body's most mobile joint, which makes it susceptible to dislocation.

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. Coracoacromial ligament (secondary socket) Triangular band Base –attached to lateral margin of coracoid process Apex – attached to tip of acromion Coracoid process,ligament & acromion together form – coracoacromial arch Which forms secondary socket for the joint … 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. subacromial bursa is present just below acromion process and above the ball and socket joint of the shoulder. 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. • The muscles surrounding the joint undergo reflex spasm in response to pain … Shoulder arthritis occurs when the cartilage starts wearing down on the ball and/or socket sides of the shoulder joint. A ball-and-socket joint that facilitates forward, circular, and backward movement of the shoulder. • The joint is sensitive to pain, pressure, excessive traction, and distension.

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). The synovial membrane of the joint capsule is mainly . 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. Symptoms of shoulder arthritis may include pain in the shoulder joint, stiffness and reduced range of motion. In the tip of the shoulder, there is bony prominence, it is an acromion process. 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. Shoulder instability occurs when the head of the upper arm bone is forced out of the shoulder 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. Shoulder osteoarthritis can be either primary or secondary. attached to the labrum, covering its inner surface, and at the anatomical neck of the humerus. 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 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. 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 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. is held against the socket rather than fitting into it.
