The hand and wrist are made up of many small joints that work together to perform fine motor movements. Coordination of the fingers, hand, and wrist is needed to carry out daily tasks involving grasping, gripping, and pinching.
Carpal tunnel syndrome is a condition caused by compression of the median nerve at the wrist. This occurs as the median nerve moves through a narrow passageway called the carpal tunnel. Carpal tunnel syndrome results in numbness and tingling in...
Tenosynovitis results from inflammation of the protective covering, called the sheath, that surrounds a tendon. De Quervain tenosynovitis results from inflammation of the tendon sheath that surrounds two tendons of the thumb.
Collagen is a protein that makes up connective tissue throughout the body. When collagen is overproduced, it results in connective tissue disorders, including Dupuytren disease, which affects the fingers and hands.
The hand and fingers are made up of many small bones, which include the metacarpals (hand bones) and phalanges (finger bones). Injury involving direct impact to the hands can cause fractures in any of these bones.
Mallet finger is a common injury to the tendon that helps straighten the fingertip. When this tendon is injured, the fingertip droops down into a bent position, resembling a hammer or mallet.
The scaphoid is one of the carpal bones of the wrist. It has a boat-like shape and forms five joints with other bones in the wrist. The scaphoid is the most commonly fractured carpal bone.
The thumb is the most moveable joint in the hand, and it moves in a combination of different ways to hold and manipulate objects. Repeated strain or direct injury to the thumb can damage the supporting joint and ligaments, which...
The triangular fibrocartilage complex (TFCC) is a group of several structures, including a tendon, ligaments, and a cartilage disc, located on the pinky side of the wrist. The TFCC provides cushioning and helps maintain the stability of the wrist.
Trigger finger happens when a tendon in the finger gets stuck within its pulleys, small bands of connective tissue that keep the tendon in place. The tendon cannot move smoothly, causing the finger to lock or catch. It may bend...
A broken wrist, also called a wrist fracture, is a common injury typically caused by a fall onto an outstretched hand. Some wrist fractures can be simple in nature and require little intervention. Others can be complex and need surgery...
The wrist is made up of several carpal bones held together by supporting ligaments. If any of these ligaments are injured, the wrist bones can shift out of alignment, resulting in wrist instability. Wrist instability most often occurs from injuries...
