This study presents a novel cervical foraminotomy technique that achieves extensive decompression of the cervical cord and nerve roots. The innovative approach avoids complications like scar formation and foreign bodies, ensuring clear postoperative imaging.

Area of Science:

  • Neurosurgery
  • Spinal Surgery
  • Orthopedic Surgery

Background:

  • Cervical radiculopathy often requires surgical intervention for nerve root decompression.
  • Traditional cervical foraminotomy techniques may lead to complications such as scar formation and limitations in postoperative imaging.

Purpose of the Study:

  • To introduce and evaluate a modified cervical foraminotomy technique for enhanced decompression and reduced complications.
  • To assess the efficacy of using osteotomized laminae as a fulcrum and repositioned spinous processes for spinal stability.

Main Methods:

  • A novel cervical foraminotomy procedure involving bilateral osteotomy of laminae from C-3 to C-7.
  • Utilizing the incompletely severed lamina as a fulcrum to lift the laminae mass.
  • Fixation of repositioned C-6 and C-7 spinous processes between articular joints and lifted laminae.

Main Results:

  • The described technique allows for extensive decompression of the cervical cord and nerve roots.
  • The procedure effectively prevents extradural scar formation and avoids foreign body complications.
  • Postoperative neuroimaging is feasible due to the absence of metallic artifacts.

Conclusions:

  • This modified cervical foraminotomy technique offers a safe and effective method for achieving significant spinal decompression.
  • The procedure minimizes surgical complications and facilitates accurate postoperative assessment.
  • This approach represents an advancement in surgical management for cervical radiculopathies.
