Abstract
Objective:To explore the effect of screw placement on the injured vertebrae combined with pedicle screw internal fixation in the treatment of thoracolumbar fractures.Method:A total of 82 patients with thoracolumbar fractures admitted to Renhuai People's Hospital from May 2022 to April 2024 were selected and divided into the study group(n=41)and the control group(n=41)by random number table method.The control group was treated with pedicle screw internal fixation,while the study group was treated with screw placement on the injured vertebrae combined with pedicle screw internal fixation.The perioperative indicators,thoracolumbar functions,imaging indicators and the occurrence of postoperative complications of the two groups were compared.Result:There were no statistically significant differences in the comparison of hospital stay,intraoperative blood loss,postoperative drainage volume and the incidence of complications between the two groups(P>0.05).The operation time of the study group was longer than that of the control group(P<0.05).At 7 days and 3 months after the operation,the modified Oswestry disability index(ODI)scores of both groups were lower than those before the operation,and the scores of the study group were lower than those of the control group(P<0.05).At 7 days and 3 months after the operation,the central height,anterior edge height and posterior edge height of the injured vertebrae in both groups were higher than those before the operation,and the kyphosis Cobb angle of the injured vertebrae was smaller than that before the operation,moreover,the above indicators in the study group were better than those in the control group(P<0.05).Conclusion:Although the treatment of thoracolumbar fractures with screw placement on the injured vertebrae combined with pedicle screw internal fixation may prolong the operation time,it can improve the function of the thoracolumbar vertebrae,promote spinal stability,improve the imaging indicators of the injured vertebrae,and has a relatively high surgical safety.关键词
