Improved accuracy of computer-assisted cervical pedicle screw insertion

摘要: Object. The authors introduce a unique computer-assisted cervical pedicle screw (CPS) insertion technique used in conjunction with specially modified original instruments. accuracy of placement as well surgery-related outcome and complication rates were compared between two groups patients: those whom conventional manual was used. Methods. guiding system consisted awl, probe, tap screwdriver designed for CPS insertion. Using this system, real-time instrument/screw tip information three dimensionally identified each step Seventeen patients underwent fixation which surgical navigation disorders spondylotic myelopathy segmental instability or kyphosis, metastatic spinal tumor, rheumatoid spine, postlaminectomy kyphosis. rate pe...
