In orthopedic surgery, the accuracy of internal fixation is related to success procedure. past, surgeons usually placed screws freehand according anatomical landmarks or fluoroscopy images. Although there are many surgical techniques for inserting freehand, screw placement not high enough, and results can be unstable. The reported in literature varies greatly. Particularly spine, with its unique anatomy important adjacent tissues, inaccurate may lead serious complications, such as nerve...

Robot-assisted spine surgery aims to improve the accuracy of screw placement. We compared and safety between a novel robot free hand in thoracolumbar pedicle placement.Eighty patients scheduled undergo robot-assisted (40 patients) free-hand placement were included. The patients' demographic characteristics, radiographic accuracy, perioperative outcomes compared. was based on cortical violation deviation. Safety mainly included operative time, blood loss, revision, complications.A total 178...

For the spinal internal fixation procedures, connecting rods to pedicle screws are commonly used in all segments from cervical sacral spine. So far, we have only seen single vertebral screw trajectory planning methods literatures. Joint placements multi-level vertebrae with constraint of an ipsilateral rod not considered. In this paper, a method that considers screw-rod joint system both constraints and individual safety tolerance proposed. The proposed addresses three challenging jointly...

Robot-assisted open surgery (RA-OS) is now commonly used in traditional open-exposure spinal screw placement surgery. With the help of robots, robot-assisted minimally invasive (RA-MIS) can achieve less bleeding and tissue damage percutaneous insertion. While research comparing safety accuracy between RA-MIS RA-OS insufficient. This study aims to compare effects thoracic lumbar spine.This was a prospective cohort evaluating 208 patients undergoing insertions from July 2020 September 2021....
