A morphometric study was performed on ten lumbar spine fragments from adult cadavers of both genders in order to study parameters related to lumbar spine pedicles' morphometry. The pedicles were cross-sectioned on both sides at the level of their smallest diameter. Vertebrae were photographed and the morphometric study was conducted using a Minimop instrument. The following parameters were bilaterally assessed: pedicle shape and diameter, cortical walls thickness, pedicle area, cortical bone area, spongy bone area, and percentage of spongy and cortical bone of the pedicle. The vertebral pedicle of the lumbar spine has an oval shape, its vertical diameter is larger than its horizontal diameter, the medial cortical bone wall is thicker, the area of the pedicle increases towards skull-tail, and the cortical and spongy bone areas ratio is constant throughout the extension of the lumbar spine.
