Two-level anterior cervical corpectomy and fusion (ACF) with plating is reliable, but three-level ACF has a high failure rate. Consider posterior fusion for multilevel reconstructions to improve outcomes.

Area of Science:

  • Spine surgery
  • Orthopedic surgery
  • Neurosurgery

Background:

  • Multilevel anterior cervical corpectomy and fusion (ACF) can have increased morbidity.
  • Biomechanical factors associated with plated multilevel ACF require evaluation.

Purpose of the Study:

  • To identify factors contributing to graft and plate complications after multilevel ACF.
  • To evaluate the reliability of two-level versus three-level ACF reconstructions.

Main Methods:

  • Retrospective analysis of 33 patients with two-level ACF and 7 patients with three-level ACF using iliac crest grafting and fixed-plated instrumentation.
  • Assessment of neurologic status using Nurick Grading Scale and modified JOA Score.
  • Follow-up included radiographs and neurologic examinations for an average of 31.4 months.

Main Results:

  • Two-level ACF reconstructions showed a 6% failure rate.
  • Three-level ACF reconstructions demonstrated a 71% failure rate with anterior-only constructs.
  • Successful fusion was confirmed radiographically in most two-level cases.

Conclusions:

  • Two-level ACF with an anterior strut graft and fixed plate is reliable.
  • Three-level ACF with an anterior-only construct is not reliably achieved.
  • Fixed-plated design and long lever arm may contribute to three-level ACF failures; simultaneous posterior fusion should be considered.
