BACKGROUND: Percutaneous cervical nucleoplasty (PCN) is an effective treatment for cervical herniated intervertebral disc (C-HIVD). In this retrospective study, we evaluated clinical predictors that affect the successful outcome of PCN. METHODS: Fluoroscopy-guided PCN was conducted for C-HIVD by one pain physician. Successful outcome was defined as a combination of > 50% pain relief on the numerical rating scale (NRS) pain score, no increase in analgesics, and no cervical epidural steroid injection during the 3-month follow-up period...

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 aim of this study was to introduce a new method of producing three-dimensional (3D) images of vertebral venous plexuses (VVPs) by 3D-MRI with and without contrast media, to identify pathoanatomical features that might accelerate or modify spinal canal stenosis. METHODS: We used a 1.5-T MRI unit with two different 3D sequences with and without contrast media. Multi planar reconstruction (MPR) images of VVPs could be obtained by volume image subtraction methods with a workstation for dural sac from whole 3D volume MPR without contrast media, using images before and after gadoteridol injection...

In patients with pre-existent cervical spinal canal stenosis, minimal trauma, leading to neck hyperextension, can cause a significant increase of spinal cord compression. However, spinal cord injury is generally associated with major trauma and is usually not expected in patients with minor trauma. The resulting symptoms are diverse, making it even more difficult to diagnose. To illustrate the variety in symptoms at presentation, we describe two male patients aged 66 and 69. Rapid diagnosis is important as acute neurosurgical intervention may be indicated...

BACKGROUND: "White cord syndrome" is a very rare condition thought to be the result of acute reperfusion of chronically ischemic areas of the spinal cord. Its hallmark is the presence of intramedullary hyperintense signal on T2-weighted MRI sequences in a patient with unexplained neurologic deficits following a spinal cord decompression. The syndrome is rare and has been reported previously in two patients following anterior cervical decompression and fusion. CASE DESCRIPTION: Here, we report an additional case of this complication in a 68-year-old man who developed acute left-sided hemiparesis after posterior cervical decompression and fusion for cervical spondylotic myelopathy...

Context: Cervical spondylotic myelopathy (CSM) is a progressive disease that can result in significant disability. Single-level stenosis can be effectively decompressed through either anterior or posterior techniques. However, multilevel pathology can be challenging, especially in the presence of significant spinal stenosis. Three-level anterior decompression and fusion are associated with higher nonunion rates and prolonged dysphagia. Posterior multilevel laminectomies with foraminotomies jeopardize the bone stock required for stable fixation with lateral mass screws (LMSs)...
