In the published article the first sentence under the section heading Case Reports ("This study was conducted with the institutional review board approval and complied with the Health Insurance Portability and Accountability Act.") is incorrect. That sentence should be replaced with: "Case reports are exempt from IRB approval at the authors' institution. This study complied with the Health Insurance Portability and Accountability Act."

BACKGROUND: Congenital spinal stenosis (CSS) of the cervical spine is a risk factor for acute spinal cord injury and development of degenerative cervical myelopathy (DCM). OBJECTIVE: To develop magnetic resonance imaging (MRI)-based criteria to diagnose preexisting CSS and evaluate differences between patients with and without CSS. METHODS: A secondary analysis of international prospectively collected data between 2005 and 2011 was conducted...

BACKGROUND: Spinal cord injury in the cervical spine is commonly accompanied by cord compression and urgent surgical decompression may improve neurological recovery. However, the extent of spinal cord compression and its relationship to neurological recovery following traumatic thoracolumbar spinal cord injury is unclear. The purpose of this study was to quantify maximum cord compression following thoracolumbar spinal cord injury and to assess the relationship among cord compression, cord swelling, and eventual clinical outcome...

A 19-year-old woman presented with a history of severe lower backache and asymmetric proximal lower limb weakness during the past 3 months. In addition, she also suffered from lower motor neuron-type bladder and bowel symptoms. On examination, paraparesis was noted. Further, sensory examination suggested patchy asymmetric sensory loss in both lower limbs with saddle anaesthesia and areflexia. A clinical diagnosis of Conus-Cauda syndrome was made and contrast-enhanced MRI of the lumbar and sacral spine was done, which confirmed the presence of a mass lesion within the spinal canal involving the cauda equina extending up to the sacral level...

Superficial siderosis (SS) of the CNS is a rare and often unrecognized condition. Caused by hemosiderin deposition from chronic, repetitive hemorrhage in the subarachnoid space, it results in parenchymal damage in the subpial layers of the brain and spinal cord. T2-weighted MRI shows the characteristic hypointensity of hemosiderin deposition, classically occurring around the cerebellum, brainstem, and spinal cord. Patients present with progressive gait ataxia and sensorineural hearing impairment. Although there have been several studies, case reports, and review articles over the years, the clear pathophysiology of subarachnoid space hemorrhage remains to be elucidated...

The ongoing chronic inflammation and subsequent fibrosis play an important role in ligamentum flavum(LF) fibrosis and hypertrophy in patients with lumbar spinal canal stenosis (LSCS). Leptin is a chronic inflammatory mediator and involved in the fibrotic process in multiple organ systems. The present study aimed to investigate the role of leptin in LFfibrosis and its related regulatory mechanisms. The LF specimens were obtained during the surgery from 12 patients with LSCS(LSCS group) and 12 control patients with lumbar disc herniation (LDH group)...

Dural metastasis from primary gastric adenocarcinoma has been rarely reported, and its prognosis is very poor because it frequently leads to acute subdural hematoma. Here, we describe a case with sequential spinal and cranial dural metastases from gastric adenocarcinoma without subdural hematoma. A 43-year-old woman with gastric adenocarcinoma and well-controlled peritoneal carcinomatosis presented with back pain, right radiating leg pain, left facial palsy, and hearing loss. Magnetic resonance imaging of the spine and brain revealed dural masses at the lumbosacral junction with invasion to the L5 and S1 nerve roots and at the skull base with invasion to the internal auditory canal...

OBJECTIVE: We report our experience with surgery in 50 patients with C2 neurinomas. The anatomic subtleties of these discrete forms of tumors and their surgical implications are analyzed. METHODS: During the period 2006-2016, we operated on 50 patients with 55 C2 neurinomas. Type A tumors were located within the spinal canal, type B tumors were located in the lateral gutter, and type C tumors had a paraspinal extension. By working within the dural confines of the tumor and appropriately angulating the microscope, the entire tumor bulk extending into 1 or all 3 compartments was resected...

OBJECTIVE: To evaluate the musculoskeletal and soft tissue neural alterations in cases with group A basilar invagination. METHODS: Between January 2007 and August 2016, 510 patients with group A basilar invagination were surgically treated. The radiologic images of these patients were reviewed retrospectively. The patients were divided into 4 groups: group A1, comprising 60 patients with syringomyelia; group A2, comprising 354 patients with "external syrinx," marked by excessive cerebrospinal fluid (CSF) in the extramedullary space; group A3, comprising 51 patients with both syringomyelia and external syrinx; and group A4, comprising 45 patients with no abnormality of CSF cavitation in the spinal canal...

OBJECTIVE: The objective of this retrospective study was to evaluate the clinical feasibility and safety of percutaneous endoscopic decompression by uniportal, unilateral approach for the lumbar canal or lateral recess stenosis. METHODS: The procedure was performed with endoscopic instruments in the same way as with conventional microscopic laminotomy and flavectomy. Clinical outcomes (VAS, ODI, modified MacNab criteria) were evaluated. Surgical outcomes including operative time, hospital stay and complications were also investigated...

BACKGROUND: Timing of surgery and the importance of the size of disc prolapse in cauda equina syndrome (CES) remain controversial. OBJECTIVE: To investigate whether there is a relationship between postoperative urinary function, preoperative duration of neurogenic lower urinary tract dysfunction (NLUTD), and the level of canal compromise. METHODS: Seventy-one patients operated for CES were prospectively identified between 2010 and 2013. Fifty-two cases with preoperative NLUTD were included...

Neuronal networks in the spinal cord generate and execute all locomotor-related movements by transforming descending signals from supraspinal areas into appropriate rhythmic activity patterns. In these spinal networks, neurons that arise from the same progenitor domain share similar distribution patterns, neurotransmitter phenotypes, morphological and electrophysiological features. However, subgroups of them participate in different functionally distinct microcircuits to produce locomotion at different speeds and of different modalities...

A 57-year-old woman sustained gradually progressive sensorimotor disturbance in the left upper extremity for one year. Neurological examination found a diminished sensation below the left C7 dermatome and reduced strength in the left interosseous muscles. Computed tomography of the cervical spine revealed a high density mass at C7, in the left dorsal part of the spinal canal. Magnetic resonance imaging found an enhancing, en-plaque tumor at C6-T1, involving a non-enhancing part, and considerable compression of the spinal cord...

PURPOSE: A low cost, reproducible radiographic method of diagnosing congenital lumbar spinal stenosis (CLSS) is lacking. We hypothesized that the Cobb angle for lumbar lordosis would be smaller in patients with CLSS, based on observations in our spine clinic patient population. Here, we compared lumbar lordosis Cobb angles with the radiographic ratio method in patients with normal spine imaging, degenerative spinal stenosis, and with CLSS. MATERIALS AND METHODS: Orthopedic surgeons categorized patients with low back pain as "Normal," "Degenerative spinal stenosis," and "CLSS" based on clinical presentation and findings on lumbar magnetic resonance imaging...
