ABSTRACT
Objective To investigate the correlation between lumbar curvature and lumbar intervertebral disc herniation.Methods 160 cases of young and mid-aged lumbar disc herniation patients were collected.All patients were divided into two groups accord-ing to the curvature.The age,sex,course of disease,occupation and MRI manifestations were recorded.Also,the recurrence and the arch top distance were recorded in 6 months after treatment.Results The age,sex,course of disease were similar between the two groups.70% of the patients in curvature straighten group were sitting or standing for long time in life,while in the other group more people were engaged in traditional manual work(P<0.05).The arch top distance increased in the curvature straighten group when rechecked(P<0.05).There were more patients with L4/L5 segment intervertebral disc herniation in the curvature straighten group,while more patients with L5/S1 segment intervertebral disc herniation in the other group(P<0.001).The recurrence rate was higher in the curvature straighten group,and the arch top distance was less in the patients with recurrence in both groups(P<0.05).Conclusion The patients with curvature straightening have a higher rate of recurrence and intervertebral disc herniation in L4/L5 segment.The recovery and reconstruction of the balance of the lumbar spine biomechanics is beneficial to the patients’cura-tive effect and functional recovery.
