The Ossification of the Posterior Longitudinal Ligament (OPLL) is an idiopathic degenerative spinal disease which may cause motor deficit. For patients presenting myelopathy or severe stenosis, surgical decompression is the treatment of choice; however, despite adequate decompression residual motor impairment is found in some cases. After surgery, there is no therapeutic approach available for this population. The Hybrid Assistive Limb® (HAL) robot suit is a unique powered exoskeleton designed to predict, support, and enhance the lower extremities performance of patients using their own bioelectric signals...

BACKGROUND: Laminoplasty and laminectomy are two common surgical procedures utilized in approaching degenerative and neoplastic disease of the spinal canal. Routinely adopted instruments, such as Kerrison rongeur or high-speed drill (HSD), entail some potentially serious complications such as dura injuring and thermal and mechanical damage to neurovascular structures. We have adopted piezoelectric bone surgery, which permits a selective cut of mineralized tissues, to perform posterior procedures on the thoracic spine, where the relationship between bone and the spinal cord are critical...

OBJECTIVE: A dynamic compression injury of the cervical spinal cord is widely accepted in the pathophysiology of cervical myelopathy. Flexion/extension MRI provides information on the dynamic cervical injury. To compare morphometric parameters on neutral, flexion/extension MRI in cervical spondylotic myelopathy METHODS: Patients with cervical canal stenosis who had MRI in neutral, flexion and extension positions were retrospectively reviewed. A morphometric comparison of following parameters at compression level was performed: Spinal cord (SC) area, cerebrospinal fluid (CSF) area, CSF reserve ratio (CSF/CSF plus SC)...

Cervical laminoplasty was initially described for the management of cervical myelopathy resulting from multilevel stenosis secondary to ossification of the posterior longitudinal ligament. The general concepts are preservation of the dorsal elements, preservation of segmental motion, and expansion of the spinal canal via laminar manipulation. No clear evidence suggests that laminoplasty is superior to either posterior laminectomy or anterior cervical diskectomy and fusion. However, laminoplasty has its own advantages, indications, and complications...

RATIONALE: Cervical open-door laminoplasty can enlarge the volume of the cervical vertebral canal and thus has become an effective and safe treatment for multilevel cervical disc herniation and cervical stenosis. Some post-surgery complications exist, such as reduction of cervical alignment and local kyphosis. However, aggravation of cervical disc herniation at the surgical level during short-term follow-up has not been discussed. Additionally, spontaneous disappearance of herniated disc pulposus is a common phenomenon in the lumbar region but is relatively rare in the cervical region...

PURPOSE: The Oswestry Disability Index (ODI) plays a significant role in lumbar spinal stenosis research and is used to assess patient's walking limitations. The World Health Organisation describes the constructs of walking capacity and performance and recommend measuring both to fully describe patient's walking ability. Objective methods to assess walking capacity and performance is being investigated and used alongside the traditional use of PROs. This review of the literature was made to provide an overview of relations between the ODI and outcome measures of walking capacity and performance in spinal stenosis research, and to provide a strategy for improving such measures in future research...

BACKGROUND: Decompressive laminectomy (DI) is a standard operation for lumbar spinal stenosis (LSS) patient with severe claudication symptoms for many years. However, patients whose symptom severity does not meet undergoing invasive surgery make therapeutic options into dilemma. Interspinous spacers (ISP) bridge the gap between surgical interventions and CC in management of LSS. In our study, we aim to systematically assess the two FDA-approved interspinous spacers for treatment of lumbar spinal stenosis: Superion versus X-STOP...
