Intercarpal joints

Intercarpal joints are the joints that connect the carpal bones in the human hand. They are a type of synovial joint, specifically plane joints, which allow for limited gliding movement.

Etymology

The term "intercarpal" comes from the Latin "inter-", meaning "between", and "carpus", meaning "wrist". Thus, "intercarpal" literally means "between the wrists".

Anatomy

The intercarpal joints are formed by the articulation of the proximal and distal rows of carpal bones. The proximal row includes the scaphoid, lunate, triquetrum, and pisiform bones, while the distal row includes the trapezium, trapezoid, capitate, and hamate bones.

Function

The main function of the intercarpal joints is to facilitate movement of the wrist and hand. They allow for flexion, extension, abduction, and adduction of the wrist, as well as slight rotation.

Clinical significance

Injuries or diseases affecting the intercarpal joints can lead to pain, swelling, and limited mobility of the wrist and hand. Common conditions include osteoarthritis, rheumatoid arthritis, and carpal tunnel syndrome.
