Rotator Cuff Tear
The rotator cuff is a group of tendons in the shoulder joint that provides support and enables a wide range of motion. A major injury to these tendons may result in rotator cuff tears. It is one of the most common causes of shoulder pain in middle-aged and older individuals.
Shoulder instability is a chronic condition that causes frequent dislocation of the shoulder joint.A dislocation occurs when the end of the humerus (ball portion) partially or completely dislocates from the glenoid (socket portion) of the shoulder. A partial dislocation is referred to as a subluxation whereas a complete separation is referred to as a dislocation.
Shoulder Labral Tear with Instability
Shoulder instability results when the humeral head is not held firmly within the glenoid cavity and may lead to a dislocation. Tearing, stretching or peeling of the labrum can result in shoulder instability. It can also occur with defects of the shoulder capsule and ligaments.
Subacromial Impingement Syndrome
Subacromial Impingement Syndrome (SAIS) is the inflammation and irritation of your rotator cuff tendons. This occurs when the tendons rub against the outer end of the shoulder blade (the acromion) while passing through the subacromial space during shoulder movement.
The term SLAP (superior –labrum anterior-posterior) lesion or SLAP tear refers to an injury of the superior labrum of the shoulder.The most common causes include falling on an outstretched arm, repetitive overhead actions such as throwing and lifting a heavy object. Overhead and contact sports may put you at a greater risk of developing SLAP tears.
Arthritis of the Shoulder
The term arthritis literally means inflammation of a joint but is generally used to describe any condition in which there is damage to the cartilage. Damage of the cartilage in the shoulder joint causes shoulder arthritis. Inflammation is the body's natural response to injury. The warning signs that inflammation presents are redness, swelling, heat, and pain.
Posterior Shoulder Instability
Posterior shoulder instability, also known as posterior glenohumeral instability, is a condition in which the head of the humerus (upper arm bone) dislocates or subluxes posteriorly from the glenoid (socket portion of the shoulder) as a result of significant trauma. A partial dislocation is referred to as a subluxation whereas a complete separation is referred to as a dislocation.
Multidirectional Instability of the Shoulder
Multidirectional Instability of the Shoulder may be described by the direction in which the humerus is subluxated or dislocated from the glenoid. When it occurs in several directions it is referred to as multidirectional instability./p>
Shoulder injuries most commonly occur in athletes participating in sports such as swimming, tennis, pitching, and weightlifting. The injuries are caused due to the over usage or repetitive motion of the arms.
The shoulder is the most flexible joint in the body, enabling a wide range of movements. It is a ball-and-socket joint made up of three bones, namely the humerus (upper arm bone), scapula (shoulder blade) and clavicle. The head of the humerus articulates with the socket of the scapula called the glenoid cavity.
The break or fracture of the clavicle (collarbone) is a common sports injury associated with contact sports such as football and martial arts, as well as impact sports such as motor racing. A direct blow over the shoulder that may occur during a fall on an outstretched arm or a motor vehicle accident may cause the clavicle bone to break.
