BACKGROUND Not all patients with spinal cord compression due to cervical spondylotic myelopathy (CSM) have clinical symptoms and signs. The aim of this study was to investigate and compare the imaging findings in asymptomatic and symptomatic patients with CSM with mild to moderate cervical spinal cord compression. MATERIAL AND METHODS A retrospective clinical study included 68 patients. Group A (n=30) had no symptoms and signs; group B (n=38) had symptoms and signs of cervical myelopathy. The age, sex, body mass index (BMI), history of steroid treatment, duration of symptoms, number of spondylotic cervical segments, Torg ratio, range of motion (ROM), incidence of cervical segmental instability, overall curvature of the cervical spine, direction of spinal cord compression, and spinal cord magnetic resonance imaging (MRI) signal intensity were compared...

BACKGROUND: Laminectomy with fusion (LF) and laminoplasty are two posterior-based surgical approaches for the surgical treatment of cervical spondylotic myelopathy (CSM). The decompressive effect of these approaches is thought to be primarily related to the dorsal drift of the spinal cord away from ventral compressive structures. A lesser known mechanism of spinal cord decompression following cervical LF is regression of the ventral disc osteophyte complexes which is postulated to result from the alteration of motion across the fused motion segment...

CONTEXT: The ability to preoperatively predict the outcome in cervical spondylotic myelopathy (CSM) helps in planning management and counseling the patient and family. AIMS: A simple prognostic scale, namely, the Madras Institute of Neurology Prognostic Scale (MINPS) for CSM has been proposed. SETTINGS AND DESIGN: Six well-known prognostic factors, namely, age, duration of symptoms, neurological disability (Nurick's grade), number of levels of compression, effective canal diameter, and intrinsic cord changes, have been taken into account...

Patients with apparent symptoms of cervical spondylotic myelopathy (CSM) may only show a mild compressive lesion in ordinary magnetic resonance imaging (MRI). The aim of this study was to investigate the characteristics of CSM patients with "hidden" lesions on kinetic MRI and to determine an effective treatment.Thirty-one patients with obvious spinal cord compression only on kinetic MRI were included in our study. A variety of parameters were calculated from MRI of the cervical spine at different postures. The anterior cervical decompression and fusion (ACDF) procedure were used for treatment of CSM...

BACKGROUND CONTEXT: Surgical outcome and the severity of cervical spondylotic myelopathy (CSM) are unpredictable and cannot be estimated by conventional anatomical magnetic resonance imaging (MRI). The utility of diffusion tensor imaging (DTI) to quantify the severity of CSM and to assess postoperative neurologic recovery has been investigated. However, whether conventional DTI should be applied in a clinical setting remains controversial. Neurite orientation dispersion and density imaging (NODDI) is a recently introduced model-based diffusion-weighted MRI technique that quantifies specific microstructural features related directly to neuronal morphology...

PURPOSE: To assess the extent of demyelination in cervical spondylotic myelopathy (CSM) using myelin water imaging (MWI) and electrophysiologic techniques. METHODS: Somatosensory evoked potentials (SSEPs) and MWI were acquired in 14 patients with CSM and 18 age-matched healthy controls. MWI was performed on a 3.0T whole body magnetic resonance scanner. Myelin water fraction (MWF) was extracted for the dorsal columns and whole cord. SSEPs and MWF were also compared with conventional MRI outcomes, including T2 signal intensity, compression ratio, maximum spinal cord compression (MSCC), and maximum canal compromise (MCC)...

BACKGROUND: Cervical stand-alone interbody cages have seen increasingly wider use over the plate-and-screw construct in single-level anterior cervical discectomy and fusion (ACDF) in the treatment of cervical disc herniation and degenerative spondylotic conditions. Despite positive clinical outcomes, the efficacy and safety of using these devices in contiguous multilevel ACDF has remained controversial. This report discusses a burst fracture seen as a complication in multilevel cervical stand-alone cage use...

The retrospective study aimed to investigate the indication for hypertrophy posterior longitudinal ligament (HPLL) removal in anterior decompression for cervical spondylotic myelopathy (CSM). A total of 138 consecutive patients with CSM were divided into 2 groups with developmental cervical stenosis (DCS) (group S) and non-DCS (group N), according to the Pavlov ratio. These 2 groups were subdivided into 2 further subgroups, according to whether HPLL was removed or preserved: group SR (49 patients) and group SP (32 patients) in group S, group NR (21 patients) and group NP (36 patients) in group N...

Remote gray matter pathology has been suggested rostral to the compression site in cervical spondylotic myelopathy (CSM). We therefore assessed neurodegeneration in the gray matter ventral and dorsal horns. Twenty patients with CSM and 18 healthy subjects underwent a high-resolution structural and diffusion magnetic resonance imaging protocol at vertebra C2/C3. Patients received comprehensive clinical assessments. T2*-weighted data provided cross-sectional area measurements of gray matter ventral and dorsal horns to identify atrophy...

Osseous-associated cervical spondylomyelopathy in dogs is characterized by both static and dynamic spinal cord compression; however, standard MRI methods only assess static compression. In humans with cervical spondylotic myelopathy, kinematic MRI is commonly used to diagnose dynamic spinal cord compressions. The purpose of this prospective, analytical study was to evaluate kinematic MRI as a method for characterizing the dynamic component of osseous-associated cervical spondylomyelopathy in dogs. We hypothesized that kinematic MRI would allow visualization of spinal cord compressions that were not identified with standard imaging...

OBJECTIVE In patients with cervical spondylotic myelopathy (CSM), the motor system may undergo progressive functional/structural changes rostral to the lesion, and these changes may be associated with clinical disability. The extent to which these changes have a prognostic value in the clinical recovery after surgical treatment is not yet known. In this study, magnetic resonance spectroscopy (MRS) was used to test 2 primary hypotheses. 1) Based on evidence of corticospinal and spinocerebellar, rubro-, or reticulospinal tract degeneration/dysfunction during chronic spinal cord compression, the authors hypothesized that the metabolic profile of the primary motor cortices (M1s) and cerebellum, respectively, would be altered in patients with CSM, and these alterations would be associated with the extent of the neurological disabilities...

The age related spondylotic changes may result in direct compressive and ischemic dysfunction of the spinal cord known as cervical spondylotic myelopathy (CSM). Symptoms often develop insidiously and are characterized by neck stiffness, unilateral or bilateral deep aching neck, arm and shoulder pain, and possibly stiffness or clumsiness while walking. The management available in current mainstream medicine is not satisfactory. Various Ayurvedic treatments have been in use for these manifestations. We present a case of CSM, which was treated with a combination of Panchakarma procedures and Ayurvedic oral drugs...

PURPOSE: Posterior cervical laminectomies and laminoplasties are common treatments for cervical spondylotic myelopathy. However, recent studies demonstrated that positional spinal cord compression occurred after cervical laminectomies and caused postoperative progressive myelopathy. Although there were no such reports after laminoplasties, we report two cases in which symptomatic extraordinary positional spinal cord compression occurred after laminoplasties in this paper. METHODS: This study included two patients who showed progressive myelopathy: one case after a laminectomy following failure of a single-door laminoplasty and one case after a double-door laminoplasty without interlaminar spacers...
