An attempt to produce scoliosis in young baboons by excision of the heads of ribs failed in thirteen growing animals observed for up to a year after operation. Other investigators have failed to produce scoliosis in primates by similar and other techniques that had successfully produced scoliosis in quadruped animals. The possible reasons for this are discussed, especially in the light of clinical trials that are being carried out with techniques transposed from the quadruped experimental animal to the scoliosis clinic.

Scoliosis Clinic and the Department of Human Genetics, Hadassah University Hospital, Jerusalem Scoliosis appeared in fifteen members of a family in three generations. The eight members examined showed an idiopathic type of scoliosis. Father-to-son transmission occurred more than once. Although at first appearance transmission of the scoliosis is as an autosomal dominant trait, the concept of polygenic inheritance, as has been shown in previous population studies, could also explain the inheritance in this family
