In normal joints, a firm, rubbery material called cartilage covers the end of each bone. Cartilage provides a smooth, gliding surface for joint motion and acts as a cushion between the bones.
A mucous cyst is a type of liquid-filled structure that most commonly occurs on the last joint of the fingers, the distal interphalangeal joint. It is a type of ganglion and is due to arthritis in the joint of the fingertip.
Trigger finger is the symptom of the locking of a finger or thumb in the bent position. The problem is caused by a tight tunnel or sheath at the base of the finger, in the hand.
The joint that is affected is called the metacarpophalangeal (MCP) joint. Any hard force on the thumb that pulls it away from the hand can cause damage to the ligaments.
Dupuytren’s disease is a problem that affects the hands of adults causing permanent bending of the fingers so that they cannot be straightened out any more. It commonly affects the ring and little fingers but can affect any including the thumb.
A ganglion is a type of liquid-filled structure that most commonly occurs at the wrist. It is most common on the back of the wrist but may occur on the palm-side of the wrist.
This condition results in the sheath covering the tendons at the thumb side of the wrist becoming thickened and painful. The sheath normally acts as a tunnel that holds the tendons in place and enables them to slide up and down freely when the wrist or thumb moves.
