Comparison of the results of trans-injured and cross-injured internal fixation for patients with thoracolumbar spine fractures
Objective To compare the clinical efficacy of trans-injured and cross-injured internal fixation for the treatment of thoracolumbar fractures.Methods Ninety-six patients with thoracolumbar spine fracture admitted between January 2022 and December 2022 in our hospital were selected.They were divided into trans-injured group and cross-injured group according to surgical methods,48 cases each.Perioperative indicators,radiological parameters,visual analogue scale(VAS),Oswestry disability index(ODI),and Japanese Orthopedic Association(JOA)scores were compared between the two groups.Results Intraoperative blood loss and operation time were higher in the trans-injured group than that in the cross-injured group,and hospital stay was lower than in the cross-injured group(P<0.05).The perioperative complication rate was lower in the trans-injured group than that in the cross-injured group(8.3%vs.22.9%,P=0.049).At 3-6 months and 9-12 months postoperatively,the posterior convexity angle of the local vertebral body was lower in patients in the trans-injured group than in the cross-injured group(P<0.05);the vertebral body wedge angle was lower in patients in the trans-injured group than in the cross-injured spine group(P<0.05);the heights of the anterior,intermediate,and posterior vertebral bodies were higher than those in the cross-injured group at 9-12 months postoperatively(P<0.05).VAS was lower in patients in the trans-injured group than in the cross-injured group at 2-3 weeks postoperatively,3-6 months postoperatively,and 9-12 months postoperatively(P=0.05).ODI was lower in patients in the trans-injured group than in patients in the cross-injured group at 3-6 months postoperatively and at 9-12 months postoperatively(P<0.05).JOA was higher in patients in the trans-injured group than in patients in the cross-injured group at 2-3 weeks postoperatively,3-6 months postoperatively,and 9-12 months postoperative(P<0.05).Conclusions Both trans-injured and cross-injured internal fixation are effective in treating thoracolumbar spine fractures.However,trans-injured internal fixation has better maintenance of height,as well as better outcomes.
