BACKGROUND: Cervical spondylotic myelopathy (CSM) is a common disease of aging that leads to gait instability resulting from loss of leg sensory and motor functions. The results of surgical intervention have been studied using a variety of methods, but no test has been reported that objectively measures integrative leg motor sensory functions in CSM patients. OBJECTIVE: To determine the feasibility of using a novel single leg squat (SLS) test to measure integrative motor sensory functions in patients with CSM before and after surgery...

BACKGROUND Postoperative axial symptoms (post-AS) after single-door cervical laminoplasty for cervical spondylotic myelopathy (CSM) are a common and severe complication that adversely affects normal daily activities. Their etiology remains unclear. It is important to know which preoperative factors are the most predictive of post-AS. Therefore, this study aimed to elucidate the preoperative factors affecting post-AS. MATERIAL AND METHODS A total of 102 patients with CSM who underwent single-door cervical laminoplasty between 2009 and 2015 were studied...

For the past 25 years, the field of neuroimaging has witnessed the development of several software packages for processing multi-parametric magnetic resonance imaging (mpMRI) to study the brain. These software packages are now routinely used by researchers and clinicians, and have contributed to important breakthroughs for the understanding of brain anatomy and function. However, no software package exists to process mpMRI data of the spinal cord. Despite the numerous clinical needs for such advanced mpMRI protocols (multiple sclerosis, spinal cord injury, cervical spondylotic myelopathy, etc...

PURPOSE: The generation and tissue origination of disc-associated axial pain is still under exploration. This study was performed to evaluate disc-associated axial pain and to explore whether it originates in the disc or its surrounding components. METHODS: A 6-year series of 88 single-level Smith-Robinson disc and posterior longitudinal ligament (PLL) resections performed to treat single-level cervical spondylotic myelopathy was retrospectively examined. All single-level anterior disc decompressions were performed under local infiltration anesthesia; the PLL was not anesthetized to avoid cervical cord block...

Although several studies report various treatment solutions for cervical spondylotic myelopathy in patients with athetoid cerebral palsy, long-term follow-up studies are very rare. None of the reported treatment solutions represent a gold standard for this disease owing to the small number of cases and lack of long-term follow-up. This study aimed to evaluate the outcomes of laminoplasty with lateral mass screw fixation to treat cervical spondylotic myelopathy in patients with athetoid cerebral palsy from a single center...

PURPOSE: The purpose of this study was to examine the movement of the spinal cord and its relationship to the spinal canal in patients with mild spondylosis using kinetic magnetic resonance imaging (kMRI). METHODS: Weight-bearing, multiposition kMRI was performed on symptomatic patients through a full range of flexion-extension. A total of 52 study patients were selected based on the C2-C7 Cobb angle of sagittal alignment: lordotic (from 30 to 45 degrees). We evaluated dynamic changes in different parameters from flexion-extension: spinal canal diameter (CD), spinal cord diameter (SCD), space available for the cord, anterior space available for the cord (ASAC), posterior space available for the cord (PSAC), average distance between the anterior canal and the cord (d-value), and global angle for the spinal canal and cord...

STUDY DESIGN: Retrospective clinical series. OBJECTIVE: To compare perioperative parameters, clinical outcomes, radiographic parameters, and complication rates of 3 reconstructive techniques after the anterior decompression of 4-level CSM. SUMMARY OF BACKGROUND DATA: At present, the decision to treat multilevel cervical spondylotic myelopathy (CSM) especially 4-level CSM remains controversial. No one compares multilevel anterior cervical discectomy and fusion (mACDF), segmental anterior cervical corpectomy and fusion (sACCF) to multilevel anterior cervical discectomy and fusion with cage alone (mACDF-CA) in 4-level constructs...

We review the pathophysiology and imaging findings of acute traumatic spinal cord injury (SCI), cervical spondylotic myelopathy, and briefly review the much less common cord herniation as a unique cause of myelopathy. Acute traumatic SCI is devastating to the patient and the costs to society are staggering. There are currently no "cures" for SCI and the only accepted pharmacologic treatment regimen for traumatic SCI is currently being questioned. Evaluation and prognostication of SCI is a demanding area with significant deficiencies, including lack of biomarkers...

INTRODUCTION: Although appropriate dorsal migration of the spinal cord is a desired end point of cervical laminoplasty, it is difficult to predict in advance the spinal cord position after surgery and to control it during surgery. The aim of the present study was to investigate the factors that affect postoperative spinal cord position after cervical laminoplasty using multivariable analysis. MATERIALS AND METHODS: We retrospectively assessed 56 consecutive patients with cervical spondylotic myelopathy treated by open-door laminoplasty...
