The term "navicular" refers to a small, boat-shaped bone found in the foot and wrist. In the foot, the navicular bone is located in the midfoot, playing a crucial role in maintaining the arch and providing stability during movement. It connects to several other bones, including the talus and cuneiforms. In the wrist, the navicular bone is also known as the scaphoid. It is one of the carpal bones and is essential for wrist mobility. Injuries to the navicular bone, particularly in the wrist, can lead to complications if not treated properly, as it has a limited blood supply.
