Sep 10, 2024 — Os odontoideum (plural: ossa odontoidea) is an anatomic variant of the odontoid process of C2 and needs to be differentiated from persistent ossiculum terminale and from a type 2 odontoid fracture. It can be associated with atlantoaxial instability.
Os Odontoideum - Physiopedia
Os odontoideum (OO) is a rare anomaly of the second cervical vertebrae characterised by a separation of a portion of the odontoid process (also called the dens) from the body of the axis. The little bone is marked by a small oval corticated ossicle of which the size can range.
Os Odontoideum - StatPearls - NCBI Bookshelf
Feb 27, 2024 — Os odontoideum is a rare cervical anomaly stemming from a developmental failure in the odontoid process. This condition has an uncertain estimated prevalence, primarily due to its typically asymptomatic nature and the lack of extensive screening studies.
Os Odontoideum: A Comprehensive Clinical and Surgical Review
Os odontoideum (OO) is a congenital anomaly of the second cervical vertebra (axis), defined as a smooth, independent ossicle of variable size and shape separated from the base of a shortened odontoid process by an obvious gap, with no osseous connection to the body of C2 [1].
Os Odontoideum - Columbia Neurosurgery in New York City
Os odontoideum is a condition that involves the second vertebra (bone) in the neck. In os odontoideum, a specific part of this vertebra is detached from the rest of the bone. The spine in the neck is called the cervical spine.
