A retrospective analysis of patients undergoing spinal deformity correction surgery by the assistance intraoperative computed tomography (iCT) with or without navigation system.To share our preliminary experience and iCT system applied to surgery.The has been shown improve accuracy safety in posterior instrumentation. It not only decreased operation time but also prevented excessive radiation exposure medical staff. To date, there are few reports about application surgery.From April 2009 September 2010, 59 who had a diagnosis scoliosis, kyphosis, scoliokyphosis underwent iCT-assisted surgical were included. Without randomization, 28 operated iCT-navigation system, other 31 standard procedure under assistance. The detailed procedures, preoperative images illustrated. screw placement, for insertion, postoperative rate, scanning data analyzed.There significant differences between 2 groups (1) Cobb angle (76.2° 62.6° non-navigation groups), (2) revision rate thoracic pedicle screws total screws, (3) average insertion time. breach significantly lower was lesser group than group. There no statistically difference lumbar mean time-out, number fusion segments, (4) scans, (5) rate. Complications encountered none reoperation due implant malposition both groups.The provides desirable instrumentation during staff, especially spine Meanwhile, itself is an effective means assessing complex deformity.
