synchondrosis

{{Short description|Hyaline cartilage joint of two bones}}

A synchondrosis (or primary cartilaginous joint) is a type of cartilaginous joint where hyaline cartilage completely joins together two bones.{{Cite web|last=Dixon|first=Andrew|title=Synchondrosis {{!}} Radiology Reference Article {{!}} Radiopaedia.org|url=https://radiopaedia.org/articles/synchondrosis?lang=gb|access-date=2020-06-12|website=Radiopaedia|language=en-GB}} Synchondroses are different from symphyses (secondary cartilaginous joints), which are formed of fibrocartilage, and from synostosis (ossified junctions), which is the fusion of two or more bones. Synchondroses are immovable joints and are thus referred to as synarthroses.{{Citation needed span|text=are all synchondroses synarthrotic/immovable|date=March 2022|reason=https://med.libretexts.org/Bookshelves/Anatomy_and_Physiology/Book%3A_Anatomy_and_Physiology_(Boundless)/8%3A_Joints/8.3%3A_Cartilaginous_Joints/8.3A%3A_Cartilaginous_Joints%3A_Synchodroses}}
