Trapezium

From WikiMD's Wellnesspedia

Trapezium is a bone located in the wrist of humans. It is situated between the scaphoid and the first metacarpal bone (the metacarpal of the thumb). It is on the radial side of the carpal tunnel.

Anatomy[edit | edit source]

The trapezium is distinguished by a deep groove on its anterior surface. It is situated at the radial side of the carpal tunnel. This bone is deeply concave and smooth for articulation with the base of the first metacarpal bone. The trapezium is one of the eight carpal bones of the hand.

Function[edit | edit source]

The trapezium, along with the other carpal bones, forms part of the wrist, which provides support to the hand. The trapezium is specifically involved in the thumb's movements, as it articulates with the first metacarpal bone.

Clinical significance[edit | edit source]

Injuries to the trapezium, including fractures, can cause pain, swelling, and a decreased range of motion in the wrist. These injuries are diagnosed through physical examination and imaging studies, such as X-rays. Treatment may involve immobilization with a cast or splint, pain medication, and in severe cases, surgery.
