Prevalence of lumbar spondylolisthesis in adults and elderly patients with low back pain in the Jordanian community: radiographic findings
摘要
Lumbar spondylolisthesis (LS) defined as the displacement of a vertebral body relative to the vertebra below it. Moreover, it typically affects the lower lumbar spine, particularly in women above 50 years of age. Many studies showed that the prevalence of LS increases with age and reported a higher number of cases in women. This study aimed to determine the prevalence of lumbar spondylolisthesis in adults and elderly people in the Jordanian community.
MethodsA total of 2000 patients with low back pain, aged 18–94 years, with records of their age, gender, and lumbar spine X-ray from Jordan University Hospital were included in this retrospective cross-sectional study. The anterior-posterior (AP) and lateral lumbosacral X-ray images of every subject under study were read using SYNAPSE Viewer. Finally, the IBM SPSS Statistics program was used for statistical analysis.
ResultsAmong the 1,458 subjects included in the study, 910 (62.4%) were females and 548 (37.6%) were males. Their mean age was (53.2 ± 16.1) years. A total of 385 subjects had lumbar spondylolisthesis, with a total incidence of 26.4%. The percentage of Spondylolisthesis among males was (16.1%) and (32.6%) among females. The rates of spondylolisthesis (P = 0.00) were significantly higher in females. There was no significant difference between prevalence of males and females in patients under 50 years old. But the prevalence of LS in patients who are over 50 years old increased significantly, compared to other age groups. So our results showed that as the age of the patients increased, the prevalence increased in both males and females (P = 0.01). There were 385 cases that had slipped at different level, sorting in prevalence as follows L4-L5 > L5-S1 > L3-L4 > L2-L3 > L1-L2. We noticed that the L4-L5 in females took the largest proportion, but in males L4-L5 and L5-S1 took almost the same proportion. The majority of our patients had LS only at one level, with a percentage of 94.3% among all cases.
ConclusionThe total prevalence of LS in adults and the elderly in Jordanian community was 26.4%. The results of our study showed that spondylolisthesis is more common in females and may be more common among older individuals. Finally, spondylolisthesis was most seen at the L4/L5 and L5-S1 levels, and mostly at one level.
