Posterior Cervical Laminoplasty

104 Posterior Cervical Laminoplasty
Zoher Ghogawala




♦ Preoperative


Imaging



  • Cervical spine magnetic resonance imaging (MRI)
  • Cervical spine computed tomography (CT) (to evaluate for ossification of the posterior longitudinal ligament)
  • Cervical spine flexion-extension plain films

Equipment



  • Choose laminoplasty system: ceramic spacers, titanium miniplates, etc.
  • Operating loupes or microscope

Spinal Monitoring



  • Somatosensory evoked potentials and electromyography monitoring are commonly used in cervical myelopathy cases

Anesthetic Issues



  • General endotracheal anesthesia, consider fiberoptic intubation
  • Review specific anesthetic management (e.g., no paralytics for monitoring nerve roots).
  • Spinal monitoring leads should be placed prior to positioning. In cases of myelopathy or severe canal stenosis, baseline somatosensory evoked potentials are often obtained prior to positioning.
  • Foley catheter is generally inserted.
  • Intravenous antibiotics are administered.

♦ Intraoperative (Fig. 104.1)


Positioning



  • Position patient prone with all appropriate pressure points supported
  • Protect the axilla to prevent brachial plexus stretch injury
  • Lateral intraoperative fluoroscopy is used to identify the operative levels and to confirm neutral or lordotic alignment of the cervical spine
