Cervical corpectomy is efficient for spinal cord decompression, especially when anterior components (disk osteophyte, OPLL...) bulge in the spinal cord. A three or more level corpectomy was not considered in this series since they may be associated to high rate morbidity. We found that this decompression led to better clinical results in patient grades 0 and 1 and to poorer results as myelopathy progressed. Among complications, subsidence was the most frequent specific one, but since it was rarely associated with symptoms, the majority of patients were successfully treated conservatively.
