Expansive laminoplasty as a method for managing cervical multilevel spondylotic myelopathy.

Study Design: This study evaluated 12 patients with multilevel cervical spondylotic myelopathy who underwent Kurokawa's procedure using hydroxyapatite spacers and performed with T-saw thread wire.

Objectives: To assess the efficacy and safety of Kurokawa's laminoplasty for patients with multilevel cervical spondylotic myelopathy using the T-saw, and to determine the radiographic and clinical factors that correlate with the prognosis.

Summary Of Background Data: Spinous process-splitting laminoplasty as an alternative or a combined method with an anterior approach was evaluated for the management of multilevel stenosis of the cervical spine.
