Sagittal clefting of the body and other vertebral developmental errors in Canadian Inuit skeletons
Abstract The objective of this study was to determine the expression, distribution in the column, and overall frequency of sagittal clefting of the vertebral body in the skeletons of two Canadian Inuit groups. One group, referred to as Thule‐Historic, lived along the coast northwest of Hudson Bay, w...

Sagittal clefting was found to occur with high frequency in the two Inuit series, especially in the region T6–T10. Segmentation errors were found to occur in approximately the same region of the column, while spina bifida produced a completely different pattern, occurring primarily at T11 and S1. The T11 involvement is limited to females, while S1 involvement occurs primarily in males. Sagittal clefting and spina bifida occur in the same individual more frequently than sagittal clefting and segmentation error. Possibly reflecting the smaller population size and isolated location of the Sadlermiut, sagittal clefting was found with greater frequency and intensity in the skeletons of this group than in those of the Thule‐Historic Inuit.
