Morphological characteristics of the lumbar segment above the lumbosacral transitional vertebrae and its clinical significance
Objective To study morphological characteristics of the lumbar segment above the lumbosacral transitional vertebrae, and provide anatomic basis for the clinical treatment in the spondylolisthesis, lumbar disc herniation and pedicle screw fixation. Methods 59 specimens of dry lumbar segment above the lumbosacral transitional vertebrae were anatomically evaluated. The anteroposterior diameter, the transverse diameter, the thickness and height of the vertebral isthmus, the longitudinal diameter and transverse diameter of the vertebral pedicle, the height and thickness of the vertebral lamina, the spine index, and the degeneration state were measured with the caliper and the protractor in all specimens. Results The anteroposterior diameter and transverse diameter of vertebral isthmus were（34.1±2.7）mm and（47.5±4.6）mm respectively. The height of vertebral isthmus was（12.9±1.6）mm, and the thickness (9.0±1.2）mm. The longitudinal and transverse diameters of vertebral pedicle were（10.6±2.4）mm and (14.0±2.4）mm respectively. The height of the lamina was（18.2±2.6）mm, and the thickness （5.7±1.2）mm. The spine index was （1：4.35）. The hyperplasia of upper vertebra appeared in 48 specimens. Spondylolysis was not found in all specimens. Conclusions The vertebral body of lumbar segment above the lumbosacral transitional vertebrae and the transverse diameters of the vertebral pedicle are larger than that of the fourth lumbar vertebrae，which is the support for selecting the larger screws for pedicle fixation. The isthmus thickness of lumbar segment above the lumbosacral transitional vertebrae is larger than that of the fourth lumbar vertebrae，however, congenital developmental defects and weak are not found.
