[A comparative study on treatment of lumbar degenerative disease with osteoporosis by manual and robot-assisted cortical bone trajectory screws fixation].

摘要

OBJECTIVE: To compare the safety and accuracy of manual and robot-assisted cortical bone trajectory (CBT) screws fixation in the treatment of lumbar degenerative diseases with osteoporosis. METHODS: >0.05), with comparability. The accuracy of implant was evaluated by Kaito's grading method, and the invasion of CBT screw to the superior articular process was evaluated by Babu's method. RESULTS: =0.000). No serious injury of spinal cord, nerve, and blood vessel was found in the two groups. One patient in group A had delayed cerebrospinal fluid leakage, and 2 patients in group B had mild anemia. Both groups were followed up 10-14 months (mean, 11.6 months). The neurological symptoms were improved, and no screw loosening or fracture was found during the follow-up. CONCLUSION: Compared with manual implantation of CBT screw, robot-assisted spinal implant has higher accuracy, lower incidence of invasion of superior articular process, and strong holding power of CBT screw, which can be applied to the treatment of lumbar degenerative diseases with osteoporosis.
