Efficacy and safety of open or minimally invasive surgery for spinal trauma and risk factors for postoperative deep vein thrombosis

Objective: To compare the efficacy and safety of open or minimally invasive surgery for spinal trauma (ST) and to analyze the risk factors for postoperative deep vein thrombosis. Method: 220 patients with ST were randomly divided into the control group (N = 110) treated with open surgery and the observation group (N = 110) treated with minimally invasive ST surgery. The clinical efficacy, SF-36 score, ADL scale score and the incidences of postoperative complications, etc. were compared between the two groups, and the risk factors for deep venous thrombosis after surgery were determined by multivariate logistic analysis. Results: The SF-36 and ADL scores of the control group were significantly lower than those of the observation group after treatment. The blood loss, operative time, VAS score, the length of hospital stay, and the time to ground activity of the control group were significantly higher than those of the observation group (P>0.05), and the clinical efficacy of the observation group was significantly higher than that of the control group (P<0.05). There were differences in the incidences of deep venous thrombosis between the two groups (P<0.05). Age >= 60 years old, BMI >23 kg/m(2), DD dimer >= 200 (mu g/L), receiving open surgery, operation time >150 min, hospitalization time >11 d, time to get out of bed for the first time >45 h were risk factors for deep venous thrombosis in patients. Conclusion: Compared with open surgery, minimally invasive surgery could effectively reduce complications, improve the clinical efficacy and reduce the risk of deep venous thrombosis in patients.
