Summary

Horizontal motorized static traction effectively reduces herniated disc size and psoas muscle thickness in patients with lumbar disc herniation (LDH). This treatment also increases spinal canal area and neural foramina width, offering significant relief.

Area of Science:

  • Orthopedics
  • Neurosurgery
  • Radiology

Background:

  • Previous studies suggest spinal traction reduces disc compression and herniation.
  • Lumbar disc herniation (LDH) is a common condition causing pain and neurological deficits.
  • Quantitative assessment of traction's effects on spinal structures is crucial.

Purpose of the Study:

  • To quantitatively evaluate the effects of horizontal motorized static traction on spinal anatomic structures in patients with acute LDH.
  • To assess traction's impact on herniated disc area, spinal canal area, intervertebral disc heights, neural foraminal diameter, and psoas muscle thickness.
  • To analyze traction's efficacy based on herniation localization and spinal level.

Main Methods:

  • Thirty-two patients with acute LDH underwent horizontal motorized static lumbar traction.

  • CT scans were performed before and during traction to measure changes in spinal canal area, herniated disc area, neural foramina width, intervertebral disc heights, and psoas muscle thickness.
  • Traction was applied using a specialized system.

    • Main Results:

    • Protruded disc area decreased by 24.5% (p = 0.0001).
    • Psoas muscle thickness decreased by 5.7% (p = 0.0001).
    • Spinal canal area increased by 21.6% (p = 0.0001), and neural foramina width increased by 26.7% (p = 0.0001).
    • Posterior intervertebral disc height significantly expanded, while anterior height remained unchanged.

    Conclusions:

    • Horizontal motorized static lumbar traction effectively reduces herniation size and psoas muscle thickness in acute LDH.
    • Traction leads to significant increases in spinal canal area and neural foramina width.
    • This study provides the first detailed quantitative evaluation of motorized horizontal lumbar traction's effects on spinal structures in LDH patients.
