- Abstract: Objective To compare the clinical efficacy and safety of lumbar intervertebral space implantation with single and two fusion devices in treatment of lumbar instability under intervertebral foraminoscopy.Methods 101 patients(101 vertebral bodies)diagnosed with L4,L5 or S1 segment Ⅰ° to Ⅱ° spondylolisthesis from January 2019 to June 2022 were enrolled and the patients were randomly divided into group A(single fusion device group)and group B(double fusion devices group)by intervertebral foraminoscopy.Among of them,there were 51 cases of vertebral spondylolisthesis in group A and 50 cases of vertebral spondylolisthesis in group B.The patients were followed up at 1 week,1 month,6 months,9 months and 15 months after surgery,and the differences in spondylolisthesis distance,intervertebral space height,intervertebral space fusion,vertebral sedimentation rate,lumbar pain visual analogue scale(VAS)and lumbar Oswerry disability index(ODI)between the two groups were compared.Results All the 101 patients were followed up throughout the whole process,and there were no significant differences in operation time,intraoperative blood loss,and postoperative drainage between the two groups(P＞0.05),and the VAS was(7.32±0.57)in group A and(7.14±0.61)in group B one week after operation,there was no significant difference between the two groups(P＜0.05).At 6 months after surgery,the ODI of group A was(27.44±9.52)%and group B was(21.89±8.46)%,and there was no significant difference between the two groups(P＞0.05).And at 6,9 and 15 months follow-up,the fusion rates of group A were 11.76%,68.63%and 90.20%,respectively,and the fusion rates of group B were 18.00%,80.00%and 96.00%,respectively,and there was significant difference between the two groups(P＜0.05).At 15 months postoperative follow-up,the intervertebral space height of group A(0.45±0.07)cm was significantly smaller than that of group B(0.58±0.06)cm,and the difference was statistically significant(P=0.038).There was no significant difference between group A and group B(0.33±0.18)mm and(0.28±0.21)mm(P=0.079)of spondylolisthesis distance.Conclusion Implantation of the double fusion devices can provide more contact area and better stability,shorten the vertebral fusion time,increase the vertebral fusion rate,and reduce the occurrence of vertebral settlement.It is worthy of clinical promotion and application.
