Anomalies Associated with Vertebral Malformations

A review of 218 patients with congenital vertebral anomalies demonstrates that 61% of patients had associated abnormalities affecting seven systems. The type of vertebral anomaly did not predict the location or type of associated abnormality. The site of vertebral anomaly did correlate with the occurrence of some associated diagnoses. The most common abnormalities associated with vertebral malformation were cranial nerve palsy, radial hypoplasia, club feet, dislocated hip, Sprengel's deformity, imperforate anus, hemifacial microsomia, and renal and cardiac anomalies. Comprehensive evaluation of patients with vertebral anomalies will be enhanced by knowledge of the type and frequency of associated anomalies.
