title: The sagittal diameter of the lumbar vertebral canal in normal adult Nigerians.
abstract: An osteometric study of the anteroposterior diameter of the lumbar vertebral canal and intervertebral foramina of normal adult Nigerians is reported. The results show that the midsagittal diameter of the canal is subject to racial variations, and is determined primarily by the thickness and orientation of the lamina and to a lesser extent by the height of the pedicle. The significance of the findings is discussed.
