The tumour originated from the navicular bone.
The term "navicular bone" or "hand navicular bone" was formerly used for the scaphoid bone, one of the carpal bones of the wrist.
Within the tarsus, it articulates with the calcaneus below and navicular in front within the talocalcaneonavicular joint.
Stress fractures most frequently occur in weight-bearing bones, such as the tibia (bone of the lower leg), metatarsals, and navicular bones (bones of the foot).
It is made up by the calcaneus, the talus, the navicular, the three cuneiforms, and the first, second, and third metatarsals.
Radiography, nuclear scans and ultrasonography may be necessary to determine soundness with special emphasis placed on the examination of the navicular bone and distal phalanx.
It most commonly describes an inflammation or degeneration of the navicular bone and its surrounding tissues, usually on the front feet.
It is caused when the navicular bone temporarily loses its blood supply.
Strictly these should be termed the proximal sesamoid bones whereas the navicular bone should be referred to as the distal sesamoid bone.
