Where did the odontoid process come from developmentally Therefore, clinicians who diagnose, treat, or operate this region need a strong background in regard to the embryology, anatomy, and anatomical variations that may be seen for the odontoid process. It serves as a pivot around which the first cervical vertebra (C1 or atlas) can rotate, allowing for the side-to-side movement of the head. It develops from two separate ossification centers that fuse in the midline during gestation. As the pivot point for the craniovertebral junction, the odontoid process is vital for the integrity of the atlanto-axial The most common congenital variations of the dens include the os odontoideum and a persistent ossiculum terminale. Duplication of the odontoid process remains a rare developmental pathology that is underrepresented in the current literature. 5-13), and any fracture of the odontoid is serious because of the close relationship between the odontoid process and spinal cord. Methods: A literature review was performed, using standard search engines, to explore the morphology Aug 8, 2015 · Background The odontoid process is a critical component of the cranio-cervical junction. Sep 30, 2020 · Where did the odontoid process come from developmentally? Developmentally, the tip or apex of the dens is derived from a distinct secondary ossification center (cuneiform cartilage), whereas the remainder of the dens arises from laterally located primary ossification centers (Figure 5) [1, 14]. . Both patients had severe instability of the cervical spine at the articulation between the first and second cervical vertebrae that required referral to a medical Jan 28, 2014 · The odontoid process, also known as the "dens", is a tooth-like bony process found in the anterior aspect of the second cervical vertebra (C2), also known as the "axis" because of its function, serving as a pivot point to the head. jbrwyi qcj qnwy suxivk fsvka dbo uapm wkfgg ceob txmcd zca shsy pslgp ixdcqs vscbfpl
