Clinical Analysis Of Short Segment Fixation Combined With Injured Vertebra Bone Graft And Simple Short Segment Fixation In The Treatment Of Thoracolumbar Fracture

Research purpose: To compare the postoperative imaging findings and curative effects of short-segment fixation combined with injured vertebral bone graft and simple short-segment fixation for thoracolumbar fractures,and to analyze short-segment fixation combined with injured vertebral graft and simple short-segment fixation.Research method: According to the inclusion criteria,46 patients with thoracolumbar fractures admitted to the Department of Orthopedics of Jingzhou Central Hospital from January 2018 to December 2019 were collected,including 33 males and 13 females,ranging in age from 25 to 56 years old.All patients had fractures.According to the AO classification of spine fractures,they are all type A fractures,and their neurological function is divided into E grade according to Frankel classification.Divided into two groups,A and B,with 23 cases in each group.Group A received short-segment fixation combined with bone grafting of the injured vertebra,and group B received simple short-segment internal fixation.Among them,there were 17 males and 6 females in group A,with an average age of(40±10.2)years;the cause of injury: 11 cases of falls,8 cases of falling from height,4 cases of traffic accident injuries;16 cases of compression fractures,7 cases of burst fractures;Damaged segments: 4 cases of T11 vertebral body,7 cases of T12 vertebral body,10 cases of L1 vertebral body,and 2cases of L2 vertebral body.Among them,there were 16 males and 7 females in group B,with an average age of(39±9.3)years;the cause of injury: 12 cases of falls,8 cases of falling from height,3 cases of traffic accident injuries;17 cases of compression fractures,6 cases of burst fractures;Damaged segments: 3 cases of T11 vertebral body,6 cases of T12 vertebral body,11 cases of L1 vertebral body,3 cases of L2 vertebral body.The collected patients were followed up for 12-18 months,and the operation time,intraoperative blood loss,measurement of the Cobb angle and the height of the anterior edge of the injured vertebra were measured before operation,3 days after operation,1 month after operation and 12 months after operation,Visual Analogue Scale Pain Score,Oswestry Disability Scores and statistical analysis.Results: 1.The gender,age,fractured vertebral body segment and the cause of injury were compared between the two groups,p>0.05,the difference was not statistically significant;2.Compared the operation time of the two groups,p<0.05,the difference is statistically significant;3.Comparison of intraoperative blood loss between the two groups,p>0.05,the difference was not statistically significant;4.The preoperative Cobb angle,the compression rate of the injured vertebrae,and the VAS score of the two groups were compared with 3 days after the operation,p<0.05,the difference was statistically significant,but the comparison between the two groups,p>0.05,there was no difference Statistical significance;5.The short-segment fixation group was compared with the Cobb angle and the compression rate of the anterior edge of the injured vertebra at 12 months after the operation and 3 days after the operation,p<0.05,the difference was statistically significant;the operation of the short-segment fixation combined with injured vertebral bone graft group Comparing the Cobb angle and the compression rate of the anterior edge of the injured vertebral in the second 12 months and 3 days after the operation,p>0.05,the difference was not statistically significant;the Cobb angle and the anterior edge of the injured vertebral The marginal compression rate was compared,p<0.05,the difference was statistically significant;6.There was significant difference in VAS score between the two groups at 1 week and 12 months after operation(p < 0.05),while there was no significant difference in VAS score between the two groups before operation,1 week after operation and 12 months after operation(p > 0.05).Conclusion: 1.For patients with single-segment thoracolumbar fractures,short-segment fixation combined with bone grafting of the injured vertebrae and simple short-segment fixation can achieve satisfactory therapeutic effects.2.Although the operation time of short-segment fixation combined with injured vertebra bone grafting is longer than that of simple short-segment fixation,in terms of long-term postoperative loss of injured vertebral height,the short-segment fixation combined with injured vertebra bone grafting group is better than simple short-segment fixation.Segment fixation group.
