OBJECTIVE: Spondylolysis, often progressing to spondylolisthesis, commonly defies conservative treatment in refractory cases, indicating a need for surgery. Robot-assisted techniques may provide a stable and effective minimally invasive approach for the treatment of lumbar spondylolysis. To compare the clinical efficacy between robot-assisted percutaneous screw fixation combined with endoscopic bone graft and conventional open screw fixation with bone graft in the treatment of lumbar spondylolysis. METHODS: A cohort study involving 43 individuals with lumbar spondylolysis who underwent surgical treatment was conducted. From January 2022 to June 2023, 20 patients underwent percutaneous screw fixation combined with endoscopic bone graft while 23 patients underwent conventional open screw fixation with bone graft. The demographic data, parameters related to robotic surgery, perioperative indicators, VAS and ODI scores, pedicle screw accuracy, radiographic fusion outcomes, and follow-up results were systematically recorded, analyzed, and then compared between the two groups. Categorical variables were analyzed using chi-square tests, and continuous variables were evaluated with t-tests or Mann-Whitney U tests following normality assessment, with statistical significance at p < 0.05. RESULTS: Compared with the conventional surgery group, the robot-assisted surgery group had significantly less intraoperative blood loss, less postoperative drainage, shorter hospital stay, less intra...
