Our fingers are often in harm's way, and our fingertips are prone to injury. A fingertip injury can involve skin, soft tissue, nerves and bone. It can involve the nail and the nailbed. These injuries can be serious, painful, and slow to heal.

If you've fractured a finger, you've broken one or more of the finger bones we call "phalanges." Each individual bone is called a "phalanx." You've got three in each finger, and two in each thumb.

This condition is an abscess that forms within the pad of the fingertip. A felon can swell dramatically, leading to significant pain and sensitivity.

If your finger is dislocated, that means a bone has been forced out of its normal position. It's a common, painful injury, and one that needs proper treatment.

This condition is a thickening of the fascia on the palm of the hand. The fascia is a connective tissue located just beneath the skin of the palm and fingers.

This condition is a break of the radius bone at the wrist. The radius is the larger of the two bones that connect the wrist to the elbow. The other bone is called the ulna.

A mucous cyst is a small, fluid-filled sac that forms on the back of the finger near the base of the fingernail. It is a form of ganglion cyst that erupts from the capsule of the joint at the end of the finger, called the DIP joint.

This condition, also called stenosing tenosynovitis of the first dorsal compartment of the wrist, is an inflammation of the sheath that wraps around the tendons at the thumb side of the wrist.

Colles fracture is a break of one or both of the forearm bones (called the radius and ulna) that occurs just above the wrist.

Pain, numbness and tingling in your hand may be from carpal tunnel syndrome. It happens when the area around the main nerve to your hand is too tight. The nerve is called the median nerve.

A boxer's fracture is a break of the metacarpal of the little finger. The metacarpals are the long bones in the hand that connect the fingers to the wrist.

This condition is a characteristic deformity of the finger in which the finger's middle joint, called the PIP joint, bends downward and the finger's end joint, called the DIP joint, hyperextends.

This is a common shoulder injury. It's a break of the bone that rests between the shoulder blade and the sternum. We call it the "collarbone." Your collarbones help connect your arms to your body.

This painful condition occurs when calcium deposits form in tendons of the rotator cuff. These tendons and surrounding tissues in the shoulder become inflamed.

The spinal column is the body's main support structure. Its thirty-three bones, called vertebrae, are divided into five regions: cervical, thoracic, lumbar, sacral and coccygeal.

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.

These are warm or painful sensations caused by an injury to the brachial plexus. This is a network of nerves that passes through your shoulder. They travel down your arm and to your hand.

This is a problem with a tendon in your shoulder. Most often, it's the "long head of biceps" tendon. It travels from the front of your upper arm to the top of your shoulder socket.

Tendons are strong bands of tissue that connect muscle to bone. With this injury, one of the tendons anchoring your biceps muscle is torn. It may be torn partially or completely.

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.
