The Shoulder

The brachial plexus is a group of nerves that come from the spinal cord in the neck and travel down the arm. These nerves control the muscles of the shoulder, elbow, wrist and hand, as well as provide feeling in the arm.

A cortisone shot can be used to treat some problems in the arm and hand. These can include trigger fingers, tendonitis, carpal tunnel syndrome, arthritis, tennis elbow and rotator cuff tendonitis. These injections usually contain a numbing medicine.

The normal shoulder joint can be thought of as a golf ball balancing on a tee. If a large enough force in the right direction is applied to the arm, the ball will dislocate from the socket, resulting in a dislocated shoulder.

Among the most common injuries to the hand and wrist in children are broken bones, also known as fractures. Children are not just small adults. Their bones have a different consistency and quality, like soft, fresh wood, as compared to when we age, our bones become more dried-out and brittle. Because children are still growing, their injuries need different evaluation, and sometimes different treatment.

Applying a heat treatment or cold treatment is a common method for treating injuries, stiffness, swelling and pain.

Nerve repair is required after a nerve is injured in such a way that it will not recover on its own. Nerves are bundles of fibers that carry messages between the brain and the rest of the body.

Nerves are the body’s “telephone wiring” system that carries messages between the brain and the rest of the body. Some nerves carry messages from the brain to muscles to make the body move. Other nerves carry messages about pain, pressure, or temperature from the body to the brain.

Arthritis describes any condition where cartilage in the joint breaks down. Normally, a joint consists of two smooth, cartilage-covered bone surfaces that fit together as a matched set and glide against one other.

The rotator cuff is the group of four muscles and tendons that surround the shoulder joint, providing strength and stability. Above the rotator cuff there is a bursa, or sac of tissue, that covers and protects the rotator cuff as it comes into close contact with bones around the shoulder. When the rotator cuff is injured or damaged, it can lead to inflammation of the bursa, called bursitis, which causes pain and loss of motion.

Scar formation is a normal response following any injury or surgery; it is the way the body heals injured structures. Scar tissue may involve only the superficial skin, or it may involve the deeper tissues beneath the skin, including nerves and tendons.

Osteoarthritis is the most common type of shoulder arthritis. This is also known as degenerative joint disease. Less common types of shoulder arthritis are rheumatoid arthritis (inflammatory) and traumatic arthritis.

A shoulder fracture can result from a fall on the shoulder, a motor vehicle accident, contact sports, etc. The type of shoulder fracture varies by age. Most fractures in children occur in the clavicle bone (collarbone). In adults, the most common fracture is of the top part of the humerus (upper arm bone).

The shoulder is a ball and socket joint that allows a wide range of movement. Injury or degradation of the joint structures, from the muscles and soft tissues to the bones, can result in shoulder pain.
