Triquetrum

From WikiMD's Wellnesspedia

Triquetrum (also known as the triangular bone, cuneiform bone, pyramidal bone, and three-cornered bone) is a carpal bone found in the human hand. It is located in the proximal row of the carpal bones, near the ulna. The triquetrum is the third most commonly fractured carpal bone.

Anatomy[edit | edit source]

The triquetrum is a small, pyramid-shaped bone that is located on the ulnar side of the wrist. It articulates with the pisiform bone, hamate bone, and lunate bone. The triquetrum is one of the eight carpal bones that make up the wrist and is the second largest of these bones.

Function[edit | edit source]

The triquetrum contributes to the flexibility and movement of the wrist. It is involved in the ulnar deviation of the wrist, as well as flexion and extension movements.

Clinical significance[edit | edit source]

Fractures of the triquetrum are the third most common carpal bone fractures, after the scaphoid and lunate bones. These fractures are often caused by a fall onto an outstretched hand. Symptoms of a triquetrum fracture include pain, swelling, and difficulty moving the wrist.
