Accessory bone

The fabella is present in 10% to 30% of individuals.[1]

An accessory bone or supernumerary bone is a bone that is not normally present in the body, but can be found as a variant in a significant number of people. It poses a risk of being misdiagnosed as bone fractures on radiography.[2]
