Study on the progression of congenital scoliosis and the experimental production of the congenital scoliosis induced by /sup 60/Co irradiation in rats

Abstract

In order to clarify the pathological mechanism of the development of congenital spinal deformities, seventy six cases with congenital spinal deformity were analysed clinically, and vertebral anomalies were produced experimentally in rats of the Wistar strain by giving /sup 60/Co irradiation (200 R) to the mother in the ninth, tenth and eleventh days of the pregnancy. The congenital vertebral anomalies were classified embryologically into the following eight groups, (1) Wedge vertebra, (2) Fused wedge vertebra, (3) Hemivertebra, (4) Fused hemivertebra, (5) Unilateral segmental failure, (6) Bilateral segmental failure, (7) Butterfly vertebra and (8) Mixed type. Out of these anomalies, the unilateral segmental failure and the imbalanced multiple hemivertebrae and wedge vertebrae proved to show a marked development of the scoliotic deformities. Vertebral anomalies were confirmed in 26 of the 101 newborn infants whose mothers were treated with /sup 60/Co irradiation in the 10th or 11th day of the pregnancy. The vertebral anomalies were either unilateral segmental failure or butterfly vertebrae located mostly at the lower thoracic, lumbar or sacral spine. A scoliotic deformity of the spine developed during the rapid growth of the body in all rats with unilateral segmental failure. From the histological examinations, it was revealed that the  More>>
