Influence of interbody fusion intervertebral fixation on adjacent joint degeneration in patients with lumbar diseases / 中国基层医药

ABSTRACT

Objective To explore the influence of interbody fusion intervertebral fixation on adjacent joint degeneration in patients with lumbar diseases .Methods 56 patients with lumbar diseases who were taken interbody fusion intervertebral fixation were selected as the research subjects ,and the adjacent intervertebral joint degeneration in patients were followed up .Results 56 patients were followed up for 24-72 months,the average time was (41.2 ± 8.3)months.The new clinical symptoms were occurred in 12 cases(21.4%),including 8 cases of low back pain, 3 patients with leg pain,1 case of lumbocrural pain.Radiographic changes occurred in 9 cases(16.1%),9 cases of patients with new clinical symptoms ,including 5 cases of osteophyte formation or exacerbation ,2 cases for adjacent segment instability ( I degree of vertebral spondylolisthesis ) ,1 case of small joint hyperplasia stage spinal stenosis , 1 case of protrusion of intervertebral disc .In 9 patients with imaging performance ,internal fixation of upper adjacent segment degeneration in 7 cases,internal fixation of the adjacent segment degeneration in 2 cases.Conclusion Inter-body fusion intervertebral fixation in the treatment of lumbar diseases ,adjacent joint is prone to degeneration ,so the destruction of adjacent joint operation should be reduced .
