Cervical Spondylotic Myelopathy and OPLL: WFNS Spine Committee Book provides an up-to-date information about contemporary care of cervical spondylotic myelopathy (CSM) and ossification of the posterior longitudinal ligament (OPLL). It discusses all aspects of the problem from historical knowledge to biomechanics, balance measurements, diagnostic imaging, electrophysiology, surgical techniques, minimally invasive approaches, and outcome analysis. It also covers the current recommendations of the WFNS Spine Committee, which were prepared at recent consensus meetings. The chapters are written by experts well-known in the field and covers many of the current practices and standards useful for spine surgeons and spine-related disciplines. This book will be a valuable guide for all neurosurgeons, orthopaedic surgeons, neurologists, physical therapists, residents, and fellows.
