Correlation analysis of the effect of postoperative drainage on surgical efficacy of thoracolumbar fractures through multifidus interspace approach
Objective To investigate correlation of the effect factors on surgical efficacythe of whether postoperative drainage through the multifidus interspace approach in the treatment of thoracolumbar fractures.Methods A total of 66 patients with thoracolumbar fractures admitted from January 2017 to December 2021 were retrospectively analyzed.According to whether postoperative drainage,36 patients were in drainage group and 30 patients were in no drainage group.In the drainage group,there were 17 males and 19 females with an average age of(55.4±9.5)years old ranging from 23 to 68 years old;in the no drainage group,there were 16 males and 14 females with an average age of(53.9±8.3)years ranging from 30 to 69 years old.A multifidus interspace approach was used in both groups.Then factores of age,gender,fracture site,injured segment,op-eration time,intraoperative blood loss,preoperative Cobb angle,preoperative vertebral anterior height ratio,preoperative Japanese Orthopaedic Association(JOA)score,preoperative visual analogue scale(VAS),preoperative Oswestry Disability In-dex(ODI)score may affect the postoperative drainage,using univariate and multivariate Logistic regression analysis to study their influence on the prognosis.The postoperative Cobb angle,anterior vertebral height ratio,JOA score,VAS and ODI were compared between the two groups.Results Univariate analysis showed that whether postoperative drainage may be related to patient age,whether injury to multiple segments,operation time,and intraoperative blood loss(P＜0.05).The multivariate anal-ysis showed that age,operation time were the main factors affecting postoperative drainage(P＜0.05).There was no significant difference in Cobb angle,anterior vertebral height loss rate,JO A score,VAS score and ODI score between the two groups at the postoperative follow-up(P＞0.05).In terms of complications,the total incidence of postoperative low back pain in the no drainage group was lower than that in the drainage group(P＜0.05).There was no significant difference in postoperative infec-tion and postoperative nerve loss between the two groups(P＞0.05).Conclusion Age and operation time are the main factors af-fecting the postoperative drainage through multifidus interspace approach for thoracolumbar fractures.And no drainage does not affect the long-term effect of the operation,on the contrary,no drainage can reduce the method of low back pain and obtain more benefits.
