Objective: The aim of this study was first to evaluate the safety and efficacy of anterior corpectomy and fusion (ACF) for cervical ossification of the posterior longitudinal ligament (OPLL) associated with developmental canal stenosis. Methods: Between May 2007 and May 2010, twenty-two patients with cervical myelopathy underwent ACF and all patients showed OPLL and developmental canal stenosis...
STUDY DESIGN Prospective cohort study. PURPOSE To identify differences in time-dependent perioperative changes between the Japanese Orthopaedic Association (JOA) score and the JOA Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) score in patients with cervical spondylotic myelopathy (CSM) and posterior longitudinal ligament (OPLL) who underwent cervical laminoplasty. OVERVIEW OF LITER...
BACKGROUND Ossification of the posterior longitudinal ligament (OPLL) of the spine is a common human myelopathy that leads to spinal cord compression. No disease-modifying drug for OPLL has been identified, whereas surgery and conservative management have been established. OBJECTIVES To evaluate the therapeutic potential of the H2 blocker famotidine for ectopic ossification in the cervical sp...
BACKGROUND AND AIMS We have utilized lift-up laminoplasty to treat patients with myelopathy caused by ossification of the posterior longitudinal ligament (OPLL) of the cervical spine. The preliminary surgical outcome with computer-assisted morphological assessment is presented. MATERIAL AND METHODS The surgical technique of lift-up laminoplasty includes standard posterior exposure of the cerv...
BACKGROUND The lateral radiograph-based system described by Tsuyama is used widely to classify ossification of the posterior longitudinal ligament (OPLL) of the cervical spine. However, OPLL is a complex 3-dimensional (3-D) lesion, not a simple and uniplanar one, which is often difficult to identify on a lateral radiograph. Furthermore, its reliability among spine surgeons has not been investig...
BACKGROUND Aim of this study was to evaluate the effectiveness of various surgical interventions for the management of cervical spondylosis due to the ossification of posterior longitudinal ligament (OPLL). METHODS After a comprehensive literature search in electronic databases, studies were selected by following pre-determined eligibility criteria. Random effects meta-analyses were performed...
Ossification of the posterior longitudinal ligament (OPLL) can cause severe and irreversible paralysis in not only the cervical spine but also the thoracolumbar spine. To date, however, the prevalence and distribution of OPLL in the whole spine has not been precisely evaluated in patients with cervical OPLL. Therefore, we conducted a multi-center study to comprehensively evaluate the prevalence...

PURPOSE We aim to perform a meta-analysis on incidence of C5 nerve root palsy (C5 palsy) for patients after cervical surgery. METHODS An extensive search of the literature was performed in PubMed/MEDLINE, Embase, the Cochrane library, CNKI, and WANFANG databases on incidence of C5 palsy from January 2007 to January 2017. Prevalence of C5 palsy related to different surgery methods was calculat...
Ossification of the posterior longitudinal ligament of the spine (OPLL) is a common disease after the middle age. OPLL frequently causes serious neurological problems due to compression of the spinal cord and/or nerve roots. OPLL occurs in patients with monogenic metabolic diseases including rickets/osteomalacia and hypoparathyroidism; however most of OPLL is idiopathic and is considered as a m...
