How is Scapulothoracic dissociation measured?
This can be quantified by measuring the scapular index, which is the distance from the midline of the spine to the medial border of the scapula of the affected side divided by that of the noninjured side.
What is Scapulothoracic dissociation?
Scapulothoracic dissociation is a condition describing a complete disruption of the scapulothoracic articulation that can be thought of as either a partial or complete internal forequarter amputation, and almost always is seen in conjunction with severe injuries to the brachial plexus and subclavian vessels.
What is Scapulothoracic dysfunction?
Scapulothoracic dyskinesis is a rare condition characterized by abnormal scapula motion leading to shoulder impingement and dysfunction.
What is the Scapulothoracic joint?
The scapulothoracic joint is not a true synovial joint. Rather, the scapulothoracic articulation is formed by the convex surface of the posterior thoracic cage and the concave surface of the anterior scapula. It is attached to the axial skeleton through the acromioclavicular joint and the sternoclavicular joint.
What is Scapulothoracic crepitus?
Scapulothoracic crepitus is the production of a grinding or snapping noise with scapulothoracic motion, which may be accompanied by pain. Scapulothoracic bursitis manifests as pain and swelling of the bursae of the scapulothoracic articulation.
What movements occur at the scapulothoracic joint?
The scapulothoracic joint allows for the complex scapular movements in relation to the thoracic cage: elevation and depression, protraction and retraction, and medial and lateral rotation.
What controls the scapulothoracic joint?
Since it has no ligaments, the scapulothoracic junction is stabilized by the synchronized actions and passive tensions of the three functional muscle units; The trapezius muscle. The serratus anterior muscle. The medial stabilizers of the scapula; levator scapulae and rhomboid muscles.
What is Percitus?
Bursitis is inflammation of a bursa. A bursa is a closed, fluid-filled sac that works as a cushion and gliding surface to reduce friction between tissues of the body. The major bursae (this is the plural of bursa) are located next to the tendons near the large joints, such as in the shoulders, elbows, hips, and knees.
What is the lift off test?
The testing movement involves the patient performing internal rotation (IR), by lifting the hand off the back while the examiner places pressure on the hand. The test is considered to be positive if the patient cannot resist, lift the hand off the back or if she/he compensates by extending the elbow and shoulder.
Why is the Scapulothoracic a false joint?
A false joint is formed where the shoulder blade glides against the thorax (the rib cage). This joint, called the scapulothoracic joint, is important because it requires that the muscles surrounding the shoulder blade work together to keep the socket lined up during shoulder movements.
