[Spinal fixed-point rotating reduction in treating lumbar disc herniation by three-dimensional MRI]

Area of Science:

• Orthopedics
• Neurosurgery
• Biomedical Engineering

Background:

• Lumbar disc herniation often involves vertebral displacement, impacting spinal biomechanics.
• The relationship between the nucleus pulposus and nerve roots is crucial in herniation pathology.

Purpose of the Study:

• To evaluate the three-dimensional positional changes of the nucleus pulposus and nerve roots after spinal fixed-point rotating reduction for lumbar disc herniation.
• To explore the underlying mechanisms of this treatment.

Main Methods:

• A cohort of 52 patients with L5-S1 lumbar disc herniation underwent spinal fixed-point rotating reduction.
• Three-dimensional MRI was utilized to assess the spatial relationship between the nucleus pulposus and nerve roots, as well as spinal and pelvic configuration changes.

Main Results:

• Treatment resolved vertebral displacement and alleviated lumbocrural pain.
• Post-treatment MRI indicated corrected spinal and pelvic curves, with no significant changes in the nucleus pulposus.
• Follow-up averaging 12 months showed no recurrence, with all patients returning to work.

Conclusions:

• Vertebral displacement in lumbar disc herniation disrupts the biomechanical properties of the nucleus pulposus and nerve roots.
• Spinal fixed-point rotating reduction effectively corrects vertebral displacement, restoring spinal balance and improving patient outcomes.
