Abstract：Objective To investigate configuration changes of functional spinal units(FSUs) in patients with prolapse of lumbar intervertebral disc.Methods Thirty patients with prolapse of lumbar intervertebral disc(typeⅢ or Ⅳ,according to the standards for lumbar malformation devised by Feng Tianyou) were treated by spinal fixed-point rotating reduction.Straight leg raising(SLR)was measured with software Adobe Photoshop in body pictures before and after treatment.Three dimensional MRI was performed before and after treatment to observe the protruded segments,relationships between the nucleus pulposus and nerve roots involved,configuration changes of FSUs of protruded segments,lumbar(pelvic) malformation due to compensation and the sagittal index(SI) of the protruded disc.Results Lumbar(pelvic) malformation of rotation and lateral bending may be related to configuration changes of FSUs of protruded segments.SLR was increased significantly after treatment(P=0.000),so was configuration of FSUs (P=0.000).There was no significant change in the SI after treatment(P=0.121).Conclusion The protruded disc may not be the determinant of clinical manifestations of prolapse of lumbar intervertebral disc in patients.Single(multiple) vertebral displacement leads to configuration changes of FSUs(combination of adjacent vertebrae and the protruded disc),and causes stress or irritation to nerve roots involved.
