Effect and prognosis of robot assisted percutaneous pedicle screw for thoracolumbar fracture.

Objective To explore the efficacy and prognosis of robot-assisted percutaneous pedicle screw (PPS) in the treatment of thoracic and lumbar spine fracture. Methods A total of 84 patients with thoracolumbar fracture were selected from Xuzhou Renci Hospital from November 2018 to November 2022, and divided into study group (42 cases with robot-assisted PPS) and control group (42 cases with free-hand PPS) according to random number rank method. Perioperative indexes, nail placement accuracy, prognostic indexes (VAS score, Cobb Angle, relative height of anterior vertebra) and incidence of postoperative complications were compared between the two groups. Results Less intraoperative blood loss, shorter fluoroscopy time, fluoroscopy times, operative time, single nail placement time and radiation exposure time, and higher nail placement accuracy were observed in the study group (P < 0.05). VAS score and Cobb Angle of the injured vertebrae were lower in the postoperative 3 d and the last follow-up, and the relative height of the injured vertebrae was higher than that before surgery in the two groups (P < 0.05). Conclusion Robot-assisted PPS in the treatment of thoracolumbar fracture has a good application effect, which can shorten the operation time, reduce the intraoperative fluoroscopy times, improve the accuracy of nail placement, and have good safety.
