Various Surgical Procedures of Cervical Laminoplasty, Mainly developed and devised in Japan

Abstract

  Cervical laminoplasty as a posterior decompression procedure instead of laminectomy had been firstly reported in Japan in 1970’s and 1980’s around the world. And its procedure has been developed and devised for a long time in Japan. Cervical laminoplasty has been mainly applied for narrow spinal canal due to cervical degenerative disorders including well-known cervical spondylotic myelopathy (CSM) and ossified posterior longitudinal ligament (OPLL) and so on.

  Various procedures of cervical laminoplasty recently have been consolidated into main two procedures, open-door laminoplasty and double open-door laminoplasty.

  In this paper, I would like to focus on its developed history and consolidated stream using our original illustrations for each cervical laminoplasty.
