A sprain is an injury to a ligament. Ligaments are the connective tissues that connect and stabilize one bone to another bone; they could be thought of as very strong tape that holds the bones together at a joint.

The degree of ligament...

"Trigger finger" and "trigger thumb", involve the pulleys and tendons in the hand that bend the fingers.

The tendons work like long ropes connecting the muscles of the forearm with the bones of the fingers and thumb. In the finger, the...

A sprain refers to an injury to the tissues surrounding and supporting a joint. This includes the ligaments and joint capsule.

The ligaments are strong structures that prevent the joint from going into abnormal positions. The capsule is a...

Ganglion cysts are very common lumps within the hand and wrist that occur adjacent to joints or tendons.

It often resembles a water balloon on a stalk, and is filled with clear fluid or gel.

The most common types are :

Dorsal...

Swan neck deformity is a finger deformity in which the distal interphalangeal joint (DIP joint) is hyperflexed, and the proximal interphalangeal joint (PIP joint) is hyperextended.

As a result, the finger resemble a swan's neck.

The scaphoid bone is one of the eight small bones that make up the "carpal bones" of the wrist. There are two rows of bones, one closer to the forearm (proximal row) and the other closer to the hand (distal row).

The scaphoid bone is...

In a normal joint, cartilage covers the end of the bones and serves as a shock absorber to allow smooth, pain-free movement. In osteoarthritis (OA, or "degenerative arthritis") the cartilage layer wears out, resulting in direct contact between...

Rheumatoid arthritis is the most common inflammatory arthritis in adults.

The word arthritis literally means "inflamed joint."

It is a chronic inflammatory degenerative disease characterized by arthritis often bilateral and...

Osteoarthritis (OA) is a progressive condition that destroys the smooth articular cartilage covering the ends of bones. Healthy joints move easily because of articular cartilage. Osteoarthritis causes this cartilage to wear away.

Arthritis literally means "inflamed joint". Normally a joint consists of two smooth, cartilage-covered bone surfaces that fit together as a matched set and that move smoothly against one other. Arthritis results when these smooth surfaces become...

Usually in middle-aged or older people, it a small lump overlying the end finger near the nail.

The cyst originates from the distal interphalangeal joint (DIP) and can cause a deformity of the nail plate by pressure on the nail matrix.

A mallet finger is a deformity of the finger caused when the tendon that straightens your finger (extensor tendon) is damaged. The finger or thumb is not able to straighten.

Kienbock's disease is a problem in the wrist caused by the loss of blood supply to the lunate.

The lunate is one of the eight small bones that make up the "carpal bones" in the wrist. There are two rows of bones: one closer to the forearm...

Any abnormal lump or bump, or "mass", is considered a tumor. The term "tumor" does not necessarily mean it is malignant or that it is a cancer. In fact, the vast majority of hand and wrist tumors are benign or non-cancerous. Any lump or bump in...

The hand is made up of many bones that form its supporting framework. This frame acts as a point of attachment for the muscles that make the wrist and fingers move.

A fracture occurs when enough force is applied to a bone to break it. When...

The hamate is one of the small bones of the wrist. The hook (hamulus) is the particular part of that bone that protrudes toward your palm, and is vulnerable to injury.

The muscles that bend or flex the fingers are called flexor muscles. These flexor muscles move the fingers through cord-like extensions called tendons, which connect the muscles to bone.

The flexor muscles start from the elbow and forearm...

A sprain refers to an injury to the tissues surrounding and supporting a joint. This includes the ligaments and joint capsule.

The ligaments are strong structures that prevent the joint from going into abnormal positions. The capsule is a...

Extensor tendons, located on the back of the hand and fingers, allow you to straighten your fingers and thumb. These tendons are attached to muscles in the forearm.

As the tendons continue into the fingers, they become flat and thin.

...

The "flexor/pronator" muscles originate off of a bony prominence of the humerus (arm bone) called the medial epicondyle, and so this condition is also called "medial epicondylitis". With medial epicondylitis, there is degeneration of the tendon's...

Lateral epicondylitis, commonly known as tennis elbow, is a painful condition involving the tendons that attach to the bone on the outside (lateral) part of the elbow.

Tendons anchor the muscle to bone. The muscle involved in this...

Dupuytren's disease is an abnormal thickening of the tissue just beneath the skin known as fascia.

This thickening occurs in the palm and can extend into the fingers. Firm cords and lumps may develop that can cause the fingers to bend into...

De Quervain's syndrome is a painful condition that affects extensor pollicis brevis (EPB) and abductor pollicis longus (EPL) tendons where they run through a tunnel named 1st extensor compartment on the thumb side of the wrist.

There is a bump of bone on the inner portion of the elbow (medial epicondyle) under which the ulnar nerve passes.

At this site, the ulnar nerve lies directly next to the bone and is susceptible to pressure.

When the pressure on the...

There is a space in the wrist called the carpal tunnel where the median nerve and nine tendons pass from the forearm into the hand.

Carpal tunnel syndrome (CTS) happens when pressure builds up from swelling in this tunnel and puts pressure...

A Boxer's fracture is most commonly a break of the neck of the fourth or fifth metacarpals, just below the head of the metacarpal.

Boutonnière deformity is a deformation of the finger in which the distal interphalangeal joint (DIP joint) is hyperextended, or bent away from the palm, while the proximal interphalangeal joint (PIP joint) is hyperflexed, or bent towards the palm...
