Five-level sub-axial cervical vertebrectomy and reconstruction: technical report

摘要

PurposeRegardless of the etiology, severe cervical deformities can be extremely debilitating and are a challenge to correct. Often a multi-modality team approach is required to safely and effectively reduce the deformity, provide adequate decompression, and ensure solid fixation and fusion. In cases of iatrogenic cervical deformity necessitating five-level corpectomy and fixation, the feasibility, safety, and durability of this procedure remains unknown.ResultsWe describe a patient who presented with debilitating pain and inability to eat due to an iatrogenic chin-on-chest cervical kyphotic deformity. The patient underwent a back–front–back staged procedure requiring five-level cervical vertebrectomy, C3–T1 anterior fixation, and occipital to T5 posterior fusion, resulting in successful reduction of cervical kyphosis from 75 to 0 degrees. At 6 months post-operatively, the patient demonstrated marked improvement in neurologic function and reported substantial improvements in neck pain-specific disability (NDI) and quality of life (SF-12 and EQ-5D).ConclusionThe feasibility and safety of five-level vertebrectomy and reconstruction for chin-on-chest deformity remains poorly described. The current case suggests that thoughtful planning that involves maximizing the patient’s health status, judicious use of traction under direct neurological examination, staged circumferential release, and design of a construct that provides anterior and posterior column support with several points of fixation beyond the axis of rotation will attenuate the risk of peri-operative morbidity and potentiate the durability of deformity correction...
