Abstract:Objective To observe the effect of PLIF surgery with bone graft alone and fusion apparatus in the treatment of osteopolitic senile degenerative lumbar spinal stenosis. Methods A total of 75 elderly patients with osteoporosis and degenerative lumbar spinal stenosis treated in the Affiliated Hospital of Hebei University of Technology from August 2019 to December 2021 were selected as subjects. By random number table method, they were divided into bone graft treatment group (38 cases) and interbody fusion cage treatment group (37 cases). Visual analog scale (VAS) and Oswestry disability index (ODI) scale were used to score and compare the two groups before and six months after surgery. The height of decompression intervertebral space before surgery, 1 month after surgery and 18 months after surgery, the length of hospitalization, hospitalization cost, and the amount of bone graft in the intervertebral space during decompression between the two groups, and the situation of bone graft fusion between the two groups 3 and 18 months after surgery were compared. Results After operation, ODI and VAS scores of the two groups were lower than those before operation, and the differences were statistically significant (P<0.05). There were no significant differences in postoperative ODI and VAS scores between the two groups (P>0.05). The overall analysis showed that there was no significant difference in the interaction between the two groups (P>0.05). The difference was statistically significant at different time points (P<0.05). Further pair-wise comparison showed that the decompression level vertebral space height of the two groups was higher than that before surgery a month after surgery, and the decompression level vertebral space height of the two groups was lower than that 1 month after surgery and 18 months after surgery, with statistical significance (P<0.05). There was no significant difference in the length of hospitalization between the two groups (P>0.05). The hospitalization cost of the interbody fusion apparatus treatment group was higher than that of the single bone graft treatment group, the amount of bone graft in the decompression intervertebral space was lower than that of the single bone graft treatment group, and the differences were statistically significant (P<0.05). Three months after surgery, the number of bone graft fusion cases in the simple bone graft treatment group was larger than that in the interbody fusion device treatment group, and the difference was statistically significant (P<0.05). There was no significant difference in the number of bone graft fusion cases between the two groups 18 months after surgery (P>0.05). Conclusion For elderly patients with osteoporotic degenerative lumbar spinal stenosis who have failed conservative treatment, posterior lumbar spinal decompression, simple bone graft fusion, and pedicle screw internal fixation can achieve economical and effective treatment.
