[Clinical aspects, diagnosis and surgical treatment of developmental anomalies of the cervical spine].

The examination of 20 patients with abnormal cervical spine has identified Klippel-Feil disease in 12 of them, isolated vertebral synostoses of the cervical spine in 8. In 2 patients with Klippel-Feil anomaly neurovascular syndrome was reported which resulted from compression of the neurovascular bundle by extra cervical ribs. Indications to surgical treatment in Klippel-Feil disease are specified. The authors performed operations to correct the cosmetic defect and relieve compression of the neurovascular bundle in neurovascular syndrome.
