The trapezium bone, also known as the trapezium, is a small and irregularly shaped bone located in the wrist joint. It is found in the base of the hand, where it articulates with four other bones to form the wrist joint known as the carpometacarpal joint of the thumb.
Typically, the trapezium bone is approximately cube-shaped and has four surfaces, but its overall shape can vary from person to person. It is situated on the radial side of the wrist, which is the side closer to the thumb.
The trapezium bone acts as an important link between the bones of the wrist and the thumb, allowing for flexion, extension, abduction, and adduction movements of the thumb. It plays a significant role in the fine motor movements of the hand, such as grasping and manipulating objects.
Injuries or conditions affecting the trapezium bone can cause pain, limited range of motion, and functional impairment. Common conditions include arthritis, fractures, ligament injuries, and degenerative changes. Treatment options for trapezium bone-related issues may include conservative approaches such as immobilization, physical therapy, and pain management, or in more severe cases, surgical interventions such as trapeziectomy (removal of the trapezium bone) or joint reconstruction procedures.
Overall, the trapezium bone is an essential component of the wrist joint and plays a crucial role in enabling the thumb's range of motion and facilitating the hand's intricate movements.
The term "trapezium bone" is derived from the Greek word "trapezion", which means "little table". This name was given to the bone due to its roughly quadrilateral shape, resembling a table. The term "bone" is added to specify that it refers to a skeletal structure.
