title: [Spinal fixed-point rotating reduction in treating lumbar disc herniation by three-dimensional MRI].
abstract: OBJECTIVE
  To observe three-dimensional space position change of nucleus pulposus and nerve root before and after treatment of lumbar disc herniation by spinal fixed-point rotating reduction, and explore the mechanisms.
  
  
  METHODS
  Totally 52 patients with L5S1 lumbar disc hernation treated by spinal fixed-point rotating reduction were collected from April 2009 to June 2011. There were 33 males and 19 females with an average age of 34.6 years old (ranged, 19 to 55). Three-dimensional MRI were performed to observe relationship between nucleus pulposus and related nerve root,configuration change of spine and pelvic on coronary MRI.
  
  
  RESULTS
  MRI showed relationship between nucleus pulposus and related nerve root mainly located on axillary, shoulder, front and surround. Vertebral displacement disappeared, lumbocrural pain alleviated after manipulative therapy. All patients were followed up from 2 to 28 months with an average of 12 months, and no recurred. All patients recovered work. Nucleus pulposus had no change,while lumbral spinal and pelvic curve changed before and after admission.
  
  
  CONCLUSIONS
  Lumbar disc herniation combined with single (multiple) vertebral displacement,can cause biomechanical properties of nucleus puplosus and related nerve root, while spinal fixed-point rotating reduction can correct vertebral displacement, recover balance between inside and outside of spinal.
