Local Kyphosis Reduces Surgical Outcomes of Expansive Open-Door Laminoplasty for Cervical Spondylotic Myelopathy

Abstract

The influence of cervical malalignment on neurologic recovery after ELAP for CSM was shown. When patients have local kyphosis exceeding 13 degrees, anterior decompression or posterior correction of kyphosis as well as ELAP should be considered. Expansive laminoplasty for CSM is best indicated for patients with local kyphosis less than 13 degrees.
