Shoulder Separation

Shoulder Separation Overview This is an injury of the acromioclavicular joint (commonly called the “AC” joint). This is the joint where the clavicle meets the scapula. A shoulder separation is a stretching or a tearing of the ligaments that support these bones. This allows the bones to move out of position. Causes A separated shoulder […]

Acromioclavicular (AC) Joint Arthritis

Acromioclavicular (AC) Joint Arthritis Overview This condition, also called AC joint arthrosis, is a degeneration of the joint at the top of the shoulder where the acromion meets the clavicle. Causes This condition, which most often affects middle-aged people, is caused by overuse of the shoulder. Occupations such as painting or construction, which require repetitive […]

Subacromial Bursitis

Subacromial Bursitis Overview This condition is a swelling of the subacromial bursa, a fluid-filled sac that creates a cushion between the acromion and the head of the humerus. Causes This condition is typically caused by excessive use of the shoulder. Occupations such as painting or construction, which require repetitive overhead motions, are common culprits. These […]

Anatomy of the Shoulder

Anatomy of the Shoulder Overview The shoulder is a complex structure made of three separate joints. They work together to give the shoulder a tremendous range of motion. Let’s take a closer look at the main parts of the shoulder’s anatomy. Bones Three bones are found in the shoulder. The humerus is the large bone […]

Calcific Tendinitis of the Shoulder (Degenerative Calcification)

Calcific Tendinitis of the Shoulder (Degenerative Calcification) Overview This painful condition occurs when calcium deposits form in tendons of the rotator cuff. These tendons and surrounding tissues in the shoulder become inflamed. This condition typically affects adults. Causes The exact cause of degenerative calcification is not known. Physicians believe it is triggered by the wear […]

Fractures of the Greater Tuberosity

Fractures of the Greater Tuberosity Overview This condition is a fracture of the bony bump that is located opposite of the head of the humerus. This type of fracture can interfere with the rotator cuff. Causes Fractures of the greater tuberosity are often caused by direct trauma to the shoulder. A person who falls with […]

Fractures of the Shoulder Blade (Scapula)

Fractures of the Shoulder Blade (Scapula) Overview This condition is a break of the scapula, the large, flat, triangular bone that contains the shoulder socket. Because the scapula is well protected by the muscles of the shoulder, scapula fractures are uncommon. Causes Most scapula fractures are caused by severe trauma, such as from a fall […]

Frozen Shoulder (Adhesive Capsulitis)

Frozen Shoulder (Adhesive Capsulitis) Overview This condition is a loss of motion or stiffness in the shoulder, usually accompanied by pain in the joint. Frozen shoulder is most common in people between the ages of 40 and 60, but can afflict anyone regardless of gender, arm preference or occupation. Causes The exact cause of this […]

Hill-Sachs Lesion

Hill-Sachs Lesion Overview This condition is a traumatic fracture of the humeral head that leaves an indentation in the bone. This changes the shape of the humeral head and can interfere with normal arm motion. Causes This condition is typically caused by dislocation of the shoulder. The humerus slips out of the socket and is […]
