OS TRIQUETRUM Meaning and
Definition
-
Os Triquetrum, also known as the Triquetral bone, is one of the eight carpal bones that make up the human wrist. Located on the lateral side of the proximal row of carpal bones, it is positioned between the Lunate bone and the Pisiform bone.
The term "Os Triquetrum" is derived from Latin, where "os" means bone and "triquetrum" translates to "three-cornered." This name is given to the bone due to its distinct shape, which resembles a triangular wedge. It is the second smallest carpal bone in the wrist and has three articular facets: a small oval-shaped facet for articulation with the Lunate bone, another oval-shaped facet for articulation with the Hamate bone, and a crescent-shaped facet for articulation with the Pisiform bone.
The Os Triquetrum plays a crucial role in maintaining stability and providing flexibility to the wrist joint. It forms an important connection between the proximal and distal rows of carpal bones, transmitting forces from the forearm to the hand during activities such as gripping and lifting. Additionally, it serves as an attachment site for several ligaments and tendons that help to stabilize and move the wrist.
Injuries to the Os Triquetrum are relatively common and can result from traumatic events, repetitive stress, or degenerative conditions. Fractures, sprains, and dislocations of this bone can cause pain, swelling, and restricted movement. A thorough examination, including imaging techniques, is often necessary to diagnose and determine the most appropriate treatment for Os Triquetrum injuries.
