Impact factors on the clinical efficacy of robot-assisted pedicle screw internal fixation in thoracolumbar fracture patients without nerve injury
摘要
Abstract
Objective:To explore impact factors on clinical efficacy of robot-assisted pedicle screw internal fixation in thoracolumbar fracture patients without nerve injury.Methods:149 thoracolumbar fracture patients without nerve injury who underwent robot-assisted pedicle screw internal fixation in Beijing Pinggu Hospital from January 2021 to March 2024 were selected.They were divided into the occurrence group(n=25,poor clinical outcomes)and the non-occurrence group(n=124,good clinical outcomes)based on the different clinical outcomes.Clinical data of the two groups of patients were compared to analyze the collinearity for the different indicators,and the indicators without collinearity were included in the logistic regression model to analyze the factors related to the poor postoperative outcomes by constructing a clinical prediction model,and the receiver operating characteristic(ROC)curves was drawn to assess the predictive ability of the model.Results:Significant differences were found in the Osteoporosis Self-screening Tool for Asians(OSTA)index,preoperative vertebral compression,bone mineral density,early postoperative weight-bearing,allogeneic red blood cell transfusion,and preoperative albumin concentration between the two groups of patients(P＜0.05).The above difference variables were subjected to VIF collinearity analysis using the R language,and there was no collinearity for each difference variable with VIF≤10 and tolerance≥0.1.These variables were included in a logistic regression model,and it was found that the degree of preoperative vertebral compression,early postoperative weight-bearing,allogeneic red blood cell transfusion,and preoperative albumin concentration were all risk factors for poor postoperative clinical outcomes(P＜0.05),and the OSTA index and bone mineral density were all protective factors for poor clinical outcomes(P＜0.05).The nomogram prediction model was developed,and the area under the ROC curve(AUC)was 0.948,indicated that the model had a good degree of risk prediction.Conclusion:OSTA index,preoperative vertebral compression,bone mineral density,early postoperative weight-bearing,allogeneic red blood cell transfusion,and preoperative albumin concentration are all independent factors affecting the postoperative clinical outcomes of thoracolumbar fracture patients,and the above indicators can provide theoretical reference for preoperative screening of high-risk groups and the adoption of relevant measures.关键词
