Your hand is a complex and unique part of your body, composed of delicate tissues and an intricate network of bones, muscles, vessels, and nerves. The ability to generate great force for activities like rock climbing while also providing the fine dexterity to play a musical instrument make the [...]

A bite from an animal can be very dangerous. Besides obvious injuries like tissue punctures and tears, bites can also introduce germs. Whether from a wild animal or from a pet, an animal bite – even one that seems minor – can cause a serious infection.
This condition is a degeneration of cartilage in the joints at the base of the thumb, collectively called the basal joint. The main component of the basal joint is the thumb carpometacarpal (CMC), joint. This joint, which allows the thumb to pivot and swivel, can wear out even early in life.
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. A boxer’s fracture refers to a break at the end of the bone nearest the knuckle, which is called the metacarpal neck.
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. And the small space in your wrist where it passes is called the carpal tunnel.
Colles fracture is a break of one or both of the forearm bones (called the radius and ulna) that occurs just above the wrist. Although this type of injury can be caused by any strong force, Colles is most often associated with trying to break a forward fall.
This is a type of chronic, long-lasting, pain. In most cases, it develops in an arm or a leg that you have previously injured. With CRPS, you may have unexplained pain that won’t go away. It may be severe, and it may spread.
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. The cyst is attached to the joint capsule […]
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. The radius supports the majority of forces at the wrist joint with its large joint surface. A fracture of the […]
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 thickened fascia can form lumps or nodules under the skin, or long thick cords of tissue that extend from the palm to the fingers. [...]
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. They are supported by a network of soft tissues that can [...]
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 injured your fingertip, you [...]
The flexor tendons of the hand are responsible for flexion of the fingers and thumb toward the palm. These long structures are connected to the flexor muscles in the forearm. An injury to one of these tendons can cause pain and inability to flex the finger or thumb and grasp with the hand. [...]
This condition is a fracture, or break, of one or more of the metacarpal bones of the hand. The fracture may be nondisplaced, in which the bones remain aligned, or displaced, in which the fractured ends shift out of alignment. Without proper treatment, the bones may not heal correctly. This can [...]
A ganglion cyst is a fluid-filled sac that forms as a herniation from a joint capsule or tendon sheath. The sac is attached to the joint or tendon sheath by a “stalk” that allows fluid to move into the pouch from the joint or sheath. The stalk functions as a valve and often limits [...]
This condition is an infection of the skin around the fingernail, usually at the side of the nail. Infections are usually mild, but may quickly increase in severity if not properly treated. Some infections may be chronic, and difficult to treat.
This condition is a common congenital anomaly that results in extra fingers or thumbs. Polydactyly can affect one or both hands, and can result in one or more extra digits. Polydactyly can also affect the feet, resulting in extra toes.
Raynaud’s phenomenon is an exaggerated form of vasoconstriction – the body’s natural response to cold and stress. It results from a spasm of the small arteries that supply blood to the fingers. This spasm temporarily decreases blood flow, resulting in cold, painful, and [...]
Rheumatoid arthritis, a condition that can attack joints throughout the body, commonly affects the joints and surrounding tendons of the wrist and fingers. It can cause the joints to become swollen, painful and possibly deformed, interfering with normal hand function and significantly impacting [...]
Rheumatoid arthritis, a condition that can attack joints throughout the body, commonly affects the joints and surrounding tendons of the wrist and fingers. It can cause the joints to become swollen, painful and possibly deformed. This can interfere with normal hand function. It can [...]
A scaphoid fracture, one of the most common types of wrist fractures, is a break in the scaphoid bone. The scaphoid, one of the most important bones in the wrist, has a limited blood supply. An improperly treated scaphoid fracture can result in significant wrist pain, arthritis, and loss of motion.
This condition is a result of tendon imbalance in the finger or thumb. In the finger, it causes a characteristic deformity in which the middle finger joint (called the PIP joint) hyperextends, and the fingertip joint (called the DIP joint) bends downward. When viewed from the side, the finger [...]
This condition, also called skier’s thumb, is an acute sprain or tear of the ulnar collateral ligament (UCL) on the ulnar side of the metacarpal-phalangeal (MCP) joint of the thumb. A related condition, called gamekeeper’s thumb, is a chronic injury that develops over time from [...]
This condition is a degenerative or traumatic tear of one or more parts of the triangular fibrocartilage complex (TFCC), which stabilizes the ulna. The TFCC is composed of a group of ligaments that form connections between the radius, ulna and the carpal bones of the hand. At the center of [...]
This common condition, also known as stenosing tenosynovitis, is a narrowing of a portion of the tendon sheath in the finger or thumb that interferes with normal finger movement. This condition most commonly affects the ring finger, but can affect any digit. It is more common in middle-aged [...]
This condition is a stretching or tearing of the volar plate, which can allow the finger to hyperextend and can interfere with normal hand function. The volar plate is a strong ligamentous structure on the underside of the finger at the point where the proximal and middle phalanx bones meet, [...]
