We experienced congenital anomalies of the cervical spine among 4961 patients in our clinic.
These anomalies were analyzed 77 cases of congenital cervical vertebral fusion (C2-C3: 28, C5-C6: 13, C3-4: 12, Occ-C1: 9 and others), 14 cases of spina bifida occulta, 125 cases of posterior ponticle of atlas, and one case of os odontoideum.
Among congenital cervical vertebral fusion 14 cases of myelopathy were observed, of which 4 cases were operated.
Congenital fusion of lower cervical vertebrae affected commonly degeneration of adjacent vertebral disc.
Congenital fusion of the occiput and the first vertebra is more frequently complicated with basilar impression and atlantoaxial subluxation.
