Differences in bone mineral density of trajectory between lumbar cortical and traditional pedicle screws

Differences in bone mineral density of trajectory between lumbar cortical and traditional pedicle screws

Abstract Background Cortical bone trajectory (CBT) has been well-known in spine surgery for obtaining improved fixation while minimizing soft tissue dissection. This study was designed to compare the bone mineral density (BMD) between the CBT and traditional trajectory (TT) by using Hounsfield unit...
