What are bones that develop in the wrong places called?

Answer 1

Answer 2

accessory ossicles in foot and accessory navicular in feet
Multiple Hereditary Exostoses in legs

There are 26 bones in the human foot. Some people have “extra bones” (accessory ossicles) which are usually congenital (present at birth) but may also be due to previous trauma. These extra bones, which can occur with any bone in the foot, can be painless (asymptomatic) and are only noticed when the foot is x-rayed. Sometimes they are painful and cause significant discomfort. This pain can usually be treated by the foot and ankle surgeon using a variety of non-surgical measures, although sometimes the extra bones may need to be surgically removed.

Multiple Hereditary Exostoses (bone outgrowth) is a genetic disease that causes bony outgrowths to appear near major joints such as the hip, knee and shoulder. The extra bone is painful when bumped and can interfere with normal joint development.

Accessory Navicular Syndrome

In the child, the bones of the foot occasionally develop abnormally and an extra bone called an accessory navicular is present towards the inside of the foot, in front of the ankle. This bone is present in approximately 10% of the general population but not large enough to cause symptoms in the majority of these individuals.
