In order to investigate the effect of intravertebral screw insertion depth on lumbar fusion, Keitaro Matsukawa et al. from the Department of Orthopedic Surgery, Musashi Murayama Medical Center National Hospital, Tokyo, Japan, performed L4/5Imaging and clinical data were studied in patients undergoing single-level posterior lumbar intervertebral fusion with cortical bone trajectory (CBT) screws (mean follow-up 32.9 months). The screw loosening and intervertebral fusion during the follow-up period were evaluated by imaging data, and the related influencing factors were analyzed. Influencing factors were included as follows: age, sex, body mass index, bone mineral density, intervertebral mobility, screw diameter, screw length, depth of screw in vertebral body (%), arthroplasty, transverse connection and cage material.
腰椎退变后路传统椎弓根螺钉固定的替代技术
Because the traditional pedicle screw insertion point is located outside the articular process, a relatively large exposure area is required, and the adduction screw tract is close to the central nerve and the anterior vasculature. Although most pedicle screw misplacement does not cause serious systemic complications clinically, 60% to 80% of the screw stability comes from cortical bone with denser pedicle. Because cancellous bone is more susceptible to osteoporosis, intravertebral pedicle screw fixation strength is often affected in patients with low bone mineral density (BMD). In view of these limitations, Alexander A Rosinski et al. discussed and analyzed the techniques that can be used to achieve stable lumbar fixation in addition to traditional pedicle screws through literature review and summary.
