New nerve root holders protect neural structures during spinal decompression surgery. This technique enhances safety and stability by minimizing retraction and preventing nerve root damage.

Area of Science:

  • Neurosurgery
  • Spinal Surgery
  • Orthopedic Surgery

Background:

  • Spinal bony decompression, particularly in the lateral recess, poses risks to nerve roots and the dural sac.
  • High-speed air drills increase the potential for iatrogenic injury to delicate neural structures.
  • Existing methods may require excessive retraction, compromising vertebral stability.

Purpose of the Study:

  • To introduce novel nerve root holders designed for enhanced protection during spinal decompression.
  • To evaluate the efficacy of these holders in conjunction with the contralateral approach for safeguarding neural elements.
  • To demonstrate a technique that avoids superfluous retraction and maintains vertebral stability.

Main Methods:

  • Adaptation of brain spatulas to create specialized nerve root holders for lumbar anatomy.

  • Utilizing the contralateral approach for microscopical visualization of the surgical field.
  • Employing the nerve root holder to protect the nerve root during high-speed air drilling for decompression.

    • Main Results:

    • The developed nerve root holders effectively protect nerve roots and the dural sac.
    • The combination of holders and contralateral approach allows visualization of deep lateral recess angles without compromising vertebral stability.
    • The technique facilitates enlargement of the periradicular space, preventing dural tearing and radicular damage.

    Conclusions:

    • Novel nerve root holders, combined with the contralateral approach, offer a safe and effective method for spinal bony decompression.
    • This technique minimizes operative injuries to neural structures and preserves vertebral stability.
    • It provides a viable alternative for procedures in the lateral recess region, avoiding the need for instrumental stabilization.
