Abstract：Objective To investigate the influence of three-dimensional navigation system on efficacy of pedicle screw placement in patients with spinal diseases complicated with vertebral axial rotation and osteoporosis .Methods In this study, 130 patients (69 cases with osteoporosis and 61 cases without osteoporosis ) were diagnosed spinal diseases compli-cated with vertebral axial rotation .They all received the treatment of pedicle screw fixation with three-dimensional naviga-tion system or X-Ray fluoroscopy.Results A total of 1 091 pedicle screws (701 screws with three-dimensional navigation system, 390 screws with X-Ray fluoroscopy) were implanted.In the patients with osteoporosis, navigation group had higher satisfaction rate, and the difference had statistical significance (P<0.05).For groups without the use of navigation sys-tem, osteoporosis group had lower rate of satisfactory screw position and the difference had statistical significance ( P<0.05).In addition, navigation group got higher satisfaction rate in Nash-Moe Grade 0 and Grade Ⅱ, and the differences had statistical significance (all P<0.05).Conclusion The use of navigation system can exactly improve the rate of pedi-cle screw position satisfaction of patients with spinal diseases complicated with vertebral axial rotation and osteoporosis , es-pecially in the Nash-Moe type Ⅱdegree and above .
