A synchondrosis (or primary cartilaginous joint) is a type of cartilaginous joint where hyaline cartilage completely joins together two bones.[1] Synchondroses are different than symphyses (secondary cartilaginous joints) which are formed of fibrocartilage. Synchondroses are immovable joints and are thus referred to as synarthroses.
