♦ Preoperative


Operative Planning



  • Imaging

    • Magnetic resonance imaging (MRI)
    • Computed tomography myelogram if MRI is inconclusive
    • Flexion/extension x-rays

  • Patient counseling regarding surgical risks

    • Postoperative pain
    • Potential joint instability

Equipment



  • Basic spine tray
  • High-speed drill (Midas Rex with AM-8 bit)
  • One- and 2-mm Kerrison punches

Operating Room Set-up



  • Headlight
  • Loupes
  • Microscope
  • Bipolar cautery and Bovie cautery
  • Intraoperative x-ray
  • Intraoperative fluoroscopy
  • Mayfield head holder

Anesthetic Issues



  • Consider awake fiberoptic intubation to avoid passive neck extension
  • Assess patient’s pulmonary function for ability to tolerate prone position
  • Prophylactic intravenous antibiotics (cefazolin 2 g for adults) 30 minutes prior to incision
  • Foley catheter for prolonged surgery

♦ Intraoperative (Fig. 100.1)


Positioning



  • Prone position with appropriate padding to prevent pressure neuropathies
  • Arms tucked at sides
  • Mayfield head holder or tongs with traction to secure head in capital flexion
  • Mild reverse Trendelenburg position for venous drainage
  • Intraoperative fluoroscopic imaging used to confirm cervical alignment

Planning of Minimal Shave



  • Use disposable razor

Planning of Sterile Scrub and Preparation



  • Betadine detergent scrub with sterile gloves for 5 minutes
  • Alcohol to remove Betadine scrub
  • Sterile towel to dry
  • Incision is marked

Mark Incision



  • Localization using C2 and C7 landmarks
  • Intraoperative x-ray
  • Mark the midline incision
