Extensive four-level cervical corpectomy for cervical spondylotic myelopathy showed no unique morbidity compared to less extensive surgeries. This retrospective study analyzed 31 cases, finding acceptable complication rates for this complex procedure.

Area of Science:

  • Neurosurgery
  • Spinal Surgery
  • Orthopedics

Background:

  • Limited data exists on four-level cervical corpectomy.
  • Previous recommendations have cautioned against such extensive procedures.

Purpose of the Study:

  • To evaluate the morbidity associated with extensive anterior decompression and fusion in cervical spondylotic myelopathy.
  • To determine if four-level corpectomy presents unique risks.

Main Methods:

  • Retrospective analysis of 31 patients undergoing four-level subaxial cervical corpectomy for cervical spondylotic myelopathy.
  • Data included surgical outcomes, complications, and follow-up periods (over 2 years for 26 patients).
  • External orthosis (Philadelphia collar or halo vest) was used post-surgery; no hardware was implanted.

Main Results:

  • A 9.7% mortality rate was observed within 3 weeks of surgery.
  • Overall morbidity was 25.8%, including delayed radiculopathy, graft complications, and pseudomeningocele.
  • No cases of infection or worsened myelopathy were reported.

Conclusions:

  • Extensive subaxial decompression via four-level corpectomy does not appear to be associated with unique or inordinate morbidity.
  • The complication profile is comparable to surgeries involving fewer levels.
