Anterior decompression and fusion versus laminoplasty for cervical myelopathy caused by soft disc herniation: a prospective multicenter study

摘要

Background Anterior decompression and fusion (ADF) has conventionally been used, with stable outcomes, for cervical myelopathy caused by soft disc herniation. However, complications related to bone grafting and recurrence of myelopathy due to adjacent segment degeneration are its drawbacks. The efficacy of laminoplasty as an alternative has been sporadically reported, but no prospective study has been conducted to verify it. The purpose of this study was to determine whether laminoplasty is comparable for this condition.
