Abstract
Objective To explore the relationship between the changes of Cobb Angle and adjacent vertebra disease after PLIF surgery.Methods Retrospective analysis of 68 patients who were explicitly diagnosed with lumbar degenerative disease and underwent lumbar posterior decompression, internal fixation and fusion (PLIF) in our hospital from January 2015 to December 2016, the lesion segment is L4-5, the fusion angle of postoperative disease vertebra is greater than 5 °or not is divided into group A and group B (n = 34) , the degeneration of adjacent vertebrae was compared between the two groups.Result Group A: mean operative time (126.06 ±17.38) min, mean intraoperative blood loss (254.38 ±94.72) ml, mean postoperative drainage volume (258.62±117.67) ml, mean postoperative hospitalization time (14.65±2.67) d, postoperative JOA score (26.65±1.65) , Group B: mean operative time (130.82±18.22) min, mean intraoperative blood loss (264.65±84.59) ml, mean postoperative drainage volume (260.88± 85.89) ml, mean postoperative hospitalization time (14.44±3.09) d, postoperative JOA score (26.94±1.18) , there was no statistically significant difference between the two groups (P＞0.05) .3 cases of ASD occurred in group A after PLIF surgery, the incidence was 8.82％, the incidence in group B was 10 cases, the incidence was 29.41％, Compared between the two groups, the rate of vertebral degeneration in group B was significantly higher than that in group A (P＜0.05) , the difference was statistically significant.Conclusion For patients undergoing lumbar decompression and internal fixation fusion, the small fusion Angle of the lesion segment makes the Cobb Angle of the adjacent segment easier to change, intraoperative fusion Angle should be avoided too small, thereby reducing the incidence of the Adjacent vertebral disease.关键词
