Abstract:
Objective To observe the mid-and long-term clinical efficacy of minimally invasive transforaminal lumbar interbody fusion for the treatment of single-segment lumbar degenerative diseases. Methods Retrospective analysis of the clin-ical data of 832 patients with lumbar degenerative disease treated with single-segment MIS-TLIF surgery from 2007 to 2013, 443 males and 389 females; aged 23-82 years, mean 56.4±18.7 years old. All cases were divided into revision surgery group, severe lumbar spinal stenosis group, moderate to severe lumbar spondylolisthesis group and general case groups (as a control) for comparative analysis. Efficacy evaluation indicators include Oswestry disability index (ODI), visual analog scale (VAS), in-tervertebral fusion rate, and complications. Results All patients were followed up for 62 to 93 months, with an average of 79.2±18.6 months. One month after operation, the VAS score of low back pain in the severe spinal stenosis group 2.9±0.5 and the moderate to severe spondylolisthesis group 3.8±1.1 were both significantly higher than the general case group 1.6±0.6, and the difference was statistically significant. The VAS score of leg pain was high in the moderate to severe slip group 2.6 ± 0.7, but the difference was not statistically significant. The ODI value was significantly higher in the moderate to severe spoiler group 28.8±6.9％ than in the general case group 22.1±6.4％. In the 2 years after the operation, the vas of lower back pain was divided into 2.4 ± 0.9, compared with the general case group 1.7 ± 0.5, and the difference was statistically significant; the ODI group of severe spinal stenosis and moderate-severe spondylolisthesis were 17.9％± 3.4％ and 19.4％± 4.9％, respectively, which was higher than the general case group 11.3％±3.3％, and the difference was statistically significant. In the last follow-up, the VAS scores 2.3±0.8 and 2.6±1.1 of the severe vertebral canal stenosis group and the moderate-severe spondylolisthesis group were respectively higher than that of the general case group 1.6±0.7, and the difference was statistically significant; the ODI group of severe vertebral canal stenosis and moderate-severe spondylolisthesis were 18.3％±11.1％ and 19.6％±12.1, high-er than the general case group 11.8％± 9.7％, the difference was statistically significant. The incidence of mid- and long-term complications (intervertebral non-fusion, adjacent segment disease) was not statistically significant among the four groups. Con-clusion MIS-TLIF treatment of lumbar degenerative diseases can obtain good medium and long-term clinically effect. For complex diseases such as revision, severe degeneration and moderate to severe spondylolisthesis, MIS-TLIF did not increase the incidence of medium and long-term complications.
