AbstractVertebral bone quality is essential in vertebral strength and the stability of spinal screw fixation. A major factor of bone quality is the density of bone mineral and its distribution throughout the bone. There have been studies regarding bone mineral density variations in the cervical and thoracolumbar spine, but bone mineral density variations in the lumbosacral spine have not been documented. The purpose of the current study was to quantify bone mineral density variations at different lumbosacral levels and within vertebra, especially along the pathways of lumbar pedicle screws. Bone mineral density variations within the vertebrae along the lumbosacral spine were measured in 13 specimens from young male cadavers using peripheral quantitative computed tomography. Measurements included bone mineral density variations at different lumbosacral levels and in transverse layers and vertical columns within each vertebral body. These original data showed that the bone mineral density increased gradually from lumbar to S1 vertebrae, possibly reflecting a caudally increasing load on different lumbosacral levels. The highest bone mineral density in the lumbosacral spine is found at the pedicles and regions closest to pedicle bases, supporting the use of pedicle screw fixation.
