Study Design: Systematic review and meta-analysis. Objectives: Cervical spinal cord compression (SCC) due to degenerative changes of the spine is a frequent finding on magnetic resonance imaging (MRI). While most people remain asymptomatic, a proportion develop symptoms of degenerative cervical myelopathy (DCM). DCM is an often-progressive neurological disease that can cause quadriplegia. The epidemiology of SCC and DCM is poorly understood. We sought to estimate the prevalence of degenerative cervical SCC and DCM from cross-sectional cohorts undergoing MRI. Methods: We conducted a systematic review and meta-analysis of MRI reports on human subjects older than 16 years with degenerative SCC. A predetermined search strategy was used to identify relevant literature on MEDLINE. Title and abstract screenings were followed by full text screening. Data was extracted and analyzed by fixed or random-effects models. Results: The present search returned 1506 publications. Following our exclusion criteria, 19 studies were included. Subgroup analysis of 3786 individuals estimated the prevalence of asymptomatic SCC in a healthy population as 24.2% with a significantly higher prevalence of SCC in older populations compared with younger populations and American/European populations compared with Asian populations. Subgroup analysis of 1202 individuals estimated the prevalence of DCM in a healthy population as 2.3%. Conclusions: We present the first estimates of the prevalence of asymptomatic SCC and DCM. Studies investigating the epidemiology of SCC are heterogeneous in methodology and results. These data indicate the need for more studies into the epidemiology of SCC and DCM performed with consistent methodologies.

The authors present 2 cases involving patients who presented with myelopathy. Magnetic resonance imaging of the cervical spine showed spinal cord signal changes on T2-weighted images without any spinal cord compression. Flexion-extension plain radiographs of the spine showed no instability. Dynamic MR imaging of the cervical spine, however, showed spinal cord compression on extension. Compression of the spinal cord was caused by dynamic anulus bulging and ligamentum flavum buckling. This report emphasizes the need for dynamic MR imaging of the cervical spine for evaluating spinal cord changes on neutral position MR imaging before further workup for other causes such as demyelinating disease.

Abstract Background: Canine cervical spondylomyelopathy can be separated into osseous and disc-associated (DA-CSM) forms. Our aim was to describe the magnetic resonance imaging (using a high-field scanner) and neurological findings in dogs with DA-CSM and investigate a relationship between these findings.Results: Sixty-three dogs were included: 60/63 (95%) were large breeds, with Doberman Pinschers and males over-represented (70%). Mean and median age at the time of diagnosis was 7.25 and 7.2 years (range 0.41 – 12 years). Chronic signs were noted in 52/63 (83%) dogs, with proprioceptive ataxia the most common. Main site of spinal cord compression was commonly C6-C7 or C5-C6. Thirty-six (57%) dogs had various sites of spinal cord compression. Most dogs younger than 6 years of age had a single affected. Foraminal stenosis was present in 51/63 dogs (81%). T2-weighted hyperintensity was present in 40/63 dogs (63%). Eighty-eight percent of the articular processes showed degenerative changes, which correlated strongly with intervertebral disc degeneration. Ligamentum flavum hypertrophy was seen in 38% of dogs. No correlation was observed between neurologic signs and number of affected sites. A moderate positive correlation was observed between severity of spinal cord compression and neurologic grade (r 0.48; p<0.001).Conclusions: DA-CSM was predominantly observed in older, male Dobermans, with chronic neurologic signs, with compressive lesions located in the caudal cervical vertebral region. Although less common, DA-CSM was also seen in dogs 3 years of age or younger (8%). Single compressive lesions were more common in dogs younger than 6 years of age. Most dogs had concomitant changes (e.g.: ligamentum flavum hypertrophy and foraminal stenosis) that may affect neurologic signs. Most dogs with ligamentum flavum hypertrophy were 6 years or older. A correlation was observed between severity of spinal cord compression and neurologic grade; dogs with more severe spinal cord compression were more likely to have a higher neurologic grade. Dogs with more sites of spinal cord compression did not have more severe neurologic involvement. A very high percentage of dogs had articular process degenerative changes. Possible biomechanical or genetic relationships between degenerative changes in articular processes, ligamentum flavum, and intervertebral discs warrants further investigation.
