The term navicular bone or hand navicular bone was formerly used for the scaphoid bone, [1] one of the carpal bones of the wrist. The navicular bone in humans is located on the medial side of the foot, and articulates proximally with the talus, distally with the three cuneiform bones, and laterally with the cuboid.
Accessory navicular bone. An accessory navicular bone is an accessory bone of the foot that occasionally develops abnormally in front of the ankle towards the inside of the foot. This bone may be present in approximately 2-21% of the general population and is usually asymptomatic. [1][2][3] When it is symptomatic, surgery may be necessary.
Scaphoid bone shown in red. The scaphoid bone is one of the carpal bones of the wrist. It is situated between the hand and forearm on the thumb side of the wrist (also called the lateral or radial side). It forms the radial border of the carpal tunnel. The scaphoid bone is the largest bone of the proximal row of wrist bones, its long axis being ...
The navicular, deriving its name from its boat–like shape, is a small but critical bone. It connects the ankle with the bones of the foot. It articulates with five tarsal bones (talus, cuboid, and three cuneiform bones) forming slightly mobile syndesmotic joints and has a significant function in maintaining the arch and the dynamic ...
This bone may be present in approximately 2–21% of the general population and is usually asymptomatic. [18] [19] [20] When it is symptomatic, surgery may be necessary. The Geist classification divides the accessory navicular bones into three types. [20] Type 1: An os tibiale externum is a 2–3 mm sesamoid bone in the distal posterior ...
TA2. 1941. FMA. 35210. Anatomical terminology. [edit on Wikidata] The cuneonavicular joint is a joint (articulation) in the human foot. It is formed between the navicular bone and the three cuneiform bones. The navicular and cuneiform bones are connected by dorsal and plantar ligaments.
Anatomical terms of bone. [ edit on Wikidata] There are three cuneiform ("wedge-shaped") bones in the human foot: the first or medial cuneiform. the second or intermediate cuneiform, also known as the middle cuneiform. the third or lateral cuneiform. They are located between the navicular bone and the first, second and third metatarsal bones ...
The navicular bone is supported by several ligaments above, below, and on the side. One of these ligaments is the impar ligament, which attaches the navicular bone to the coffin bone (distal phalanx). Cartilage lies between the navicular bone and the coffin joint, as well as between the navicular bone and the DDF tendon.
