"Os Naviculare Manus" is a Latin term used in anatomy to refer to one of the small bones located in the wrist region of the human hand. Specifically, it is the name given to a boat-shaped bone situated on the inner side of the wrist, between the radius and the ulna bones.
The os naviculare manus is also commonly known as the navicular bone of the wrist. Its boat-shaped appearance gives rise to its common name "navicular," which is derived from the Latin word for ship. It is an important bone that contributes to the stability and functionality of the wrist joint.
The os naviculare manus functions as a bridge between the bones of the forearm and the bones of the hand. It acts as a crucial link in the complex network of bones that work together to facilitate the movements of the wrist and hand. It plays a vital role in allowing flexion, extension, and rotational movements of the wrist.
Injuries or abnormalities of the os naviculare manus can lead to significant functional limitations and discomfort in the affected hand. Fractures or ligament tears in this bone may result from trauma or repetitive strain, causing pain, swelling, and difficulty in performing daily activities.
Medical professionals, such as orthopedic surgeons, radiologists, and physical therapists, often refer to the term "os naviculare manus" to accurately describe and diagnose wrist conditions and to provide appropriate treatment interventions.
