Posterior midline cleft of the atlas – a crucial anatomical variation in vertebral fractures

The anatomy of the first vertebra, namely atlas, has significant clinical implications. Atlas is situated between occipital bone and second cervical vertebra (axis) one main points head movement. Most congenital anomalies are diagnosed incidentally during imaging investigations can be associated with spine anomalies. neurological symptoms may include weakness in four limbs, acute neurologic deficits such as transient quadriparesis, paraparesis, Lhermitte's sign, chronic neck pain, headache. This anomaly also commonly seen gonadal dysgenesis, Klippel-Feil syndrome, Arnold-Chiari malformations, Turner Down syndrome. Unlike other variations, which arise due to disturbances ossification posterior midline clefts different since they a developmental failure chondrogenesis. We therefore present an anatomical case analysis literature about arch atlas.
