Shoulder Instability

Shoulder Instability

Shoulder instability is a chronic condition that causes frequent dislocation of the shoulder joint.

Acromioclavicular (AC) Arthritis

Acromioclavicular (AC) Arthritis

The acromioclavicular joint is part of the shoulder joint. It is formed by the union of the acromion, a bony process of the shoulder blade, and the outer end of the collar bone or clavicle.

Acromioclavicular (AC) Joint Osteoarthritis

Acromioclavicular (AC) Joint Osteoarthritis

Osteoarthritis also called degenerative joint disease, is the most common form of arthritis. It occurs most often in older people. AC joint osteoarthritis affects the tissue covering the ends of bones (cartilage) in the AC joint of the shoulder.

Rotator Cuff Tear

Rotator Cuff Tear

A 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 Labral Tear

Shoulder Labral Tear

Traumatic injury to the shoulder or overuse of the shoulder (throwing, weightlifting) may cause the labrum to tear. In addition, aging may weaken the labrum leading to injury.

Shoulder Pain

Shoulder Pain

Pain in the shoulder may suggest an injury, which is more common in athletes participating in sports such as swimming, tennis, pitching, and weightlifting.

Rotator Cuff Pain

Rotator Cuff Pain

The rotator cuff consists of a group of tendons and muscles that surround and stabilize the shoulder joint. These tendons allow a wide range of movement of the shoulder joint across multiple planes. Irritation or injury to these tendons can result in rotator cuff pain.

Shoulder Fracture

Shoulder Fracture

A break in a bone that makes up the shoulder joint is called a shoulder fracture.

Shoulder Disorders

Shoulder Disorders

The shoulder is the most flexible joint in the body that enables a wide range of movements. Aging, trauma or sports activities can cause injuries and disorders that can range from minor sprains or strains to severe shoulder trauma.

Shoulder Dislocation

Shoulder Dislocation

Sports that involve overhead movements and repeated use of the shoulder at your workplace may lead to sliding of the upper arm bone from the glenoid.

Frozen Shoulder

Frozen Shoulder

Frozen shoulder, also called adhesive capsulitis, is a condition in which you experience pain and stiffness in your shoulder. The symptoms appear slowly, worsen gradually and usually take one to three years to resolve on their own.

Anterior Shoulder Instability

Anterior Shoulder Instability

Anterior shoulder instability, also known as anterior glenohumeral instability, is a condition in which damage to the soft tissues or bone causes the head of the humerus (upper arm bone) to dislocate or sublux from the glenoid fossa, compromising the function of the shoulder.

Posterior Shoulder Instability

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.

Shoulder Impingement

Shoulder Impingement

Shoulder impingement is the inflammation of the tendons of the shoulder joint. It is one of the most common causes of pain in the shoulder. Shoulder impingement is also called swimmer’s shoulder, tennis shoulder or rotator cuff tendinitis.

SLAP Tears

SLAP Tears

The term SLAP (superior –labrum anterior-posterior) lesion or SLAP tear refers to an injury of the superior labrum of the shoulder.

Shoulder Trauma

Shoulder Trauma

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.

Fracture of the Shoulder Blade (Scapula)

Fracture of the Shoulder Blade (Scapula)

The scapula (shoulder blade) is a flat, triangular bone providing attachment to the muscles of the back, neck, chest and arm. The scapula has a body, neck and spine portion.

Glenoid Fractures

Glenoid Fractures

Fractures of the glenoid are rare but can occur due to major trauma or during high-energy sports activities.

Proximal Humerus Fractures

Fractures of the proximal humerus are common in elderly individuals suffering from osteoporosis. In younger individuals, a severe trauma such as a fall from a height on an outstretched hand or motor vehicle accident can cause these fractures.

Little League Shoulder

Little league shoulder is an injury to the growth plate of the upper arm bone at the shoulder joint of children. It is an overuse injury caused by repeated pitching or throwing, especially in children between the ages of 10 to 15 years.

Baseball and Shoulder Injuries

Baseball and Shoulder Injuries

Shoulder injuries in baseball players are usually associated with pitching. While this overhand throwing activity can produce great speed and distance for the ball, when performed repeatedly, can place a lot of stress on the shoulder.

Sternoclavicular Joint (SC joint)

The sternoclavicular joint is the joint between the breastbone (sternum) and the collar bone (clavicle). The SC joint is one of the 4 joints that complete the shoulder and is the only joint that links the arm to the body.

Internal Impingement of the Shoulder

Internal shoulder impingement can be described as a pathological condition resulting from repetitive impingement of the internal surface of the rotator cuff by the bones at the back of the glenohumeral joint.

AC Joint Separation

AC joint separation, also known as shoulder separation, is a condition characterized by damage to the ligaments that connect the acromion to the collar bone. As a result, the bones do not line up properly, causing joint pain and instability.

Shoulder Tendonitis

Shoulder tendonitis is a condition characterized by inflammation of the tendons which connect the muscles to the shoulder bones. Tendonitis of the rotator cuff tendons is known as rotator cuff tendonitis. If the biceps tendon is affected, the condition is known as bicipital tendonitis.

Throwing Injuries of the Shoulder

Throwing Injuries of the Shoulder

Throwing injuries of the shoulder are injuries sustained as a result of trauma by athletes during sports activities that involve repetitive overhand motions of the arm as in baseball, American football, volleyball, rugby, tennis, track and field events, etc.

Partial Rotator Cuff Tear

Partial Rotator Cuff Tear

A partial rotator cuff tear is an incomplete tear that involves damage to a part of the tendon. The tear can be at the top, bottom or inner side of the tendon and does not go all the way through the tendon completely.

Shoulder Labral Tear with Instability

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.

Multidirectional Instability of the Shoulder

Multidirectional Instability of the Shoulder

Instability 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.
