Although the foregoing review of embryologic development and congenital anomalies of the spine in infants and children is necessarily brief, the most commonly encountered abnormalities have been reviewed, and when possible, an attempt has been made to cite the stage of embryologic development at which the various abnormalities originate. As noted, congenital abnormalities of the spine are relatively uncommon but may be of profound clinical significance. During the past decade, the most significant developments in the diagnosis and treatment of these abnormalities have been ultrasonography, CT scanning, and MR imaging. In the neonate, the spinal cord and neural outflow can be evaluated by ultrasonography until the osseous elements begin to fuse. Thereafter, MR imaging is the procedure of choice because it permits evaluation of the spine and spinal cord in all planes of imaging and provides detailed evaluation of the effect of osseous abnormalities on neural structures. Finally, plain radiographs of the spine for evaluation of neonates who have any of a spectrum of sacral dimples are rarely helpful, and in the presence of significant cutaneous or subcutaneous abnormalities, ultrasonography is the preferred modality for evaluation.
