Laminoplasty was developed to treat multilevel pathology of the cervical spine, namely the ossification of the posterior longitudinal ligament and cervical spondylotic myelopathy. There are many variations of the original surgical technique although all are similar in that they expand the cervical canal whilst leaving the protective posterior elements in place. This procedure has been shown to equal to other decompressive techniques and the outcome has been shown to be durable.
