There are many recorded observations on the anatomy of the vertebral column. A clear picture has been drawn on the anatomy and functions of vertebral column. Similarly, various aspects of lumbar vertebrae have been studied in the past and much of the work has been done on the morphometry of lumbar spinal canal. The present study aims to determine the normal range of lumbar vertebrae measurements in normal plain radiographs of Western Maharashtra population. Various dimensions of lumbar vertebrae from L₁ to L₅ were measured in 200 plain radiographs. Mean transverse diameter of vertebral body as well as of spinal canal were minimum at L₁ and maximum at L₅.  Making use of above parameters, canal-body ratio and intersegmental difference were calculated.  These parameters and indices can be useful in detection of clinical conditions like spinal canal stenosis and some cases of intraspinal tumours.  The present study showed regional and ethnic variation in parameters of lumbar vertebrae, thus emphasizing the need to determine normal range of values for different populations. Details will be discussed.
