Pain in the shoulder suggests a shoulder injury which is more common 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.
Shoulder impingement is the condition of inflammation of the tendons of the shoulder joint. It is one of the most common causes of pain in the adult shoulder.
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.
Rotator Cuff Tear
The rotator cuff is a group of tendons in the shoulder joint providing support and enabling a wide range of motion. Major injury to these tendons may result in tear of these tendons, a condition called rotator cuff tear.
Shoulder Labrum Tear
Traumatic injury to the shoulder or overuse of shoulder (throwing, weightlifting) may cause labral tear. In addition, ageing may weaken the labrum leading to injury.
Biceps Tendon Rupture
The biceps tendon is a tough band of connective fibrous tissue that attaches your biceps muscle to the bones in your shoulder on one side and the elbow on the other side.
Overuse and injury can cause fraying of the biceps tendon and eventual rupture.
Frozen shoulder, also called adhesive capsulitis, is a condition characterized by pain and loss of motion in the shoulder joint. It is more common in older adults aged between 40 and 60 years and is more common in women than men.
Shoulder instability is a chronic condition that causes frequent dislocations of the shoulder joint.
Playing more overhead sports and repeated use of the shoulder at the workplace may lead to sliding of the upper arm bone, the ball portion, from the glenoid–the socket portion of the shoulder. The dislocation might be a partial dislocation (subluxation) or a complete dislocation causing pain and shoulder joint instability.
A break in a bone that makes up the shoulder joint is called a shoulder fracture.
Clavicle fracture, also called broken collarbone, is a very common sports injury seen in people who are involved in 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.
Proximal Humerus Fractures
The humerus is the upper arm bone and it forms two joints —shoulder joint and elbow joint. The proximal humerus is the upper end of the arm bone that forms the shoulder joint. Fractures of the proximal humerus are common in elderly individuals suffering from osteoporosis.
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, it can place a lot of stress on the shoulder. While pitching, the arm is thrown outward and backward to generate speed.
