Abstract：Objective To study the accuracy of robot-assisted pedicle screws placement and to observe the complications relate to the placement of pedicle screws.Methods From December 2014 to May 2015, robotic-assisted screw placement was used in 13 patients (6 males and 7 females), including 2 cases of from L1 burst fracture, 1 case of L2 compression fracture in 1 case, 4 cases of L4 spondylolisthesis, 1 case of T12 bursting fracture with paraplegia, 1 case of L1 old compression fracture with kyphosis, 1 case of degenerative scoliosis, 1 case of congenital scoliosis revision, 1 case of lumbar intervertebral disc herniation with spinal stenosis and 1 case of sequela of poliomyelitis scoliosis. The mean age of the patients was 56.5 years old (range, 41-73). The accuracy of placement of the pedicle screws was evaluated according to the classification of Gertzbein and Robbins.Results Robotic-guided screw placement was successfully used in 12 out of 13 patients. In those 12 patients, 83 screws (84 planned screws) were successfully implanted. One screw was manually placed due to poor registration. According to classification of Gertzbein and Robbins, 80 screws belonged to grade A, 2 belonged to grade B, 1 belonged to grade C. And the rate of the accuracy of pedicle screws placement was 98.8%(82/83). There was no complication such as nerve root, spinal cord and vessel injury resulted from pedicle screws placement.Conclusions The accuracy of robot-assisted pedicle screws placement is high. And it can reduce or avoid the complications resulted from pedicle screws placement.
