To investigate the safety, accuracy and indications of traditional and novel cortical bone screws placement for osteoporosis lumbar spine, 4 lumbar vertebra specimens (2 males and 2 females) were used for this study. After the computed tomography scanning data of the above anatomical specimens were three-dimensional (3D) reconstructed, one side of each anatomical specimen was randomly chosen to place traditional cortical bone screws, and the other side received novel technical placement. The safety screw trajectory was designed, and a 3D navigation template complementary to the surface anatomical structure of lumbar isthmus lateral margin-vertebral plate-spinous process part was established.

Objectives: The cortical bone screw has good internal fixation effect on osteoporotic bone. In order to further increase the strength of screw track fixation in cortical bone trajectory, this study introduced a modified technique with novel insertion point and angle for cortical bone screw placement.

Methods: Cortical bone screws were placed in four dry and six wet and intact lumbar specimens according to the modified technique.
