The posterior cervical approach is the midline corridor to the posterior elements and dorsal cord/roots of the cervical spine. Through the avascular nuchal raphe it exposes the laminae, facets, and lateral masses for laminectomy, laminoplasty, laminoforaminotomy, and posterior instrumented fusion (lateral mass / pedicle screws). It is the approach for multilevel myelopathy with preserved/lordotic alignment, posterior compression, dorsal tumors, and posterior stabilization — chosen over the anterior approach when disease is multilevel/dorsal or when posterior tension-band reconstruction is required.

General Considerations

Indications

Posterior Cervical Decision Table

Problem Preferred posterior option Key caveat
Multilevel myelopathy, lordotic/neutral alignment Laminoplasty or laminectomy/fusion Posterior decompression depends on dorsal cord drift
Multilevel myelopathy with instability, kyphosis risk, or neck pain Laminectomy + fusion Preserve adjacent facets and restore alignment
Young patient with preserved lordosis and motion priority Laminoplasty Avoid if significant axial pain/instability/kyphosis
Unilateral radiculopathy from foraminal stenosis/lateral disc Posterior foraminotomy Avoid excessive facet removal; preserve stability
Trauma/facet dislocation/instability Posterior fixation ± reduction/decompression CT/CTA defines screw choices and VA risk
Fixed kyphosis with anterior compression Anterior or combined approach Posterior-only decompression may fail

Lateral Mass / Posterior Fixation

Decompression and Fixation Sequence

  1. Confirm level with fluoroscopy after exposure and again before irreversible decompression.
  2. Place pilot holes/screws before decompression when anatomy is stable and bleeding is controlled; in severe stenosis, avoid maneuvers that transmit force to the cord.
  3. Perform troughs/laminectomy with a drill until the inner cortex is thin; lift bone away from dura rather than levering into the canal.
  4. In laminoplasty, create a complete opening-side trough and controlled hinge side; avoid greenstick fracture into the canal.
  5. In foraminotomy, remove the minimum medial facet needed for root decompression and preserve at least half of the facet whenever possible.
  6. Decorticate fusion surfaces, place graft, contour rods without excessive lordosis/extension, and check final alignment and screw position.

Nuances & Pitfalls (surgeon-level)

Complications

C5 palsy; post-laminectomy kyphosis; vertebral artery or nerve root injury (screws); dural tear/CSF leak; wound infection / dehiscence (higher than anterior); axial neck pain; pseudarthrosis; epidural hematoma; positioning injuries (ION, pressure).

Chief-Level Corridor Review

Use these as the senior-level mental model for Posterior Cervical Approach (Laminectomy / Laminoplasty / Foraminotomy / Lateral Mass Fixation):

Common Pimp Questions

Use these to pressure-test preparation for Posterior Cervical Approach (Laminectomy / Laminoplasty / Foraminotomy / Lateral Mass Fixation):

  1. What patient position and head rotation make gravity work for this corridor?
  2. What named nerve, vessel, sinus, or muscle/fascial plane is most commonly injured?
  3. What bone work or soft-tissue step creates the exposure rather than simply using more retraction?
  4. What is the bailout if exposure is inadequate, bleeding occurs, or the brain is tight?
  5. What closure maneuver prevents the signature complication of this approach?
