Abstract
The aim of this study is to compare the clinical outcomes and accuracy of robot-assisted (RA) versus fluoroscopy-guided (FG) pedicle screw fixation of thoracolumbar compression fractures. We retrospectively enrolled 85 patients with surgically treated thoracolumbar compression fractures in our study (RA group, 45 patients; FG group, 40 patients). We analyzed the accuracy of pedicle screw placement by using the Gertzbein-Robbins classification, and calculated the one-time success rate (i.e., the rate of screws successfully inserted in the first attempt). We also evaluated volume of blood loss, operative time, visual analogue scale scores for pain, Cobb angle, and postoperative complications. The rates of grade A screw placement (96% vs 68.5%; P < .005), clinically acceptable screw placement (98.2% vs 86%; P < .005), and the one-time success rate (97.3% vs 82.5%; P < .005) were all significantly higher in the RA group than in the FG group. No differences were observed in sex, age, body mass index, volume of blood loss, operative time, visual analogue scale scores, Cobb angle, and postoperative complications between the 2 groups. Compared to FG surgery, RA surgery yielded greater accuracy and one-time success rates of pedicle screw fixation of thoracolumbar compression fractures, with comparable clinical outcomes.
