Adjacent Segment Diseases Following Expansive Cervical Laminoplasty: A Report of Five Cases

 Adjacent Segment Diseases Following Expansive Cervical Laminoplasty: A Report of Five Cases

Expansive laminoplasty has become the gold standard for surgical treatment of cervical multilevel compressive myelopathy. The procedure preserves the motion segment, and it has been believed hitherto that adjacent segment disease would not occur following the procedure. We report the adjacent segment disease following expansive laminoplasty for compressive cervical myelopathy and postulate on the possible pathophysiologic mechanism of the disease.
