Triquetrum
has a hook that can sometimes fracture
Triquetrum is one of the small bones that make up the wrist joint, also known as the carpus. It is triangular in shape and located on the medial side of the wrist, towards the little finger. It articulates with the proximal ends of the third metacarpal bone and the hamate bone.
The triquetrum plays an important role in wrist movement and stability. Its articulation with the hamate bone provides support for the carpal tunnel and helps to prevent compression of the median nerve. Injuries to the triquetrum can occur due to repetitive use, trauma, or overuse, and can cause pain, swelling, and restricted movement. Treatment may involve immobilization, physical therapy, medication, or surgery depending on the severity of the injury.
