BACKGROUND CONTEXT: CSM typically manifests with a slow, progressive stepwise decline in neurologic function, including hand clumsiness and balance difficulties. Gait disturbances are frequently seen in CSM patients, with more advanced cases exhibiting a stiff, spastic gait. PURPOSE: To evaluate the spatiotemporal parameters and spine and lower extremity kinematics during the gait cycle of adult cervical spondylotic myelopathy (CSM) patients prior to surgical intervention...

Cervical spondylotic myelopathy (CSM) is a degenerative pathology characterized by partial or complete conduction block on intraoperative neuromonitoring. We describe a case treated using osseoligamentous decompression and durotomy for cerebrospinal fluid (CSF) release. Intraoperative monitoring demonstrated immediate signal improvement with CSF release, suggesting that clinical improvement in CSM may result from resolution of CSF flow anomalies.

Factor XI deficiency (FXID) is a rare bleeding disorder caused by mutations in the F11 gene. Spontaneous bleeding in patients with factor XI deficiency is rare, but major bleeding may occur after surgery or trauma. The basic method for hemostatic treatment is replacement of the missing factor using FXI concentrate or fresh frozen plasma (FFP). We report the case of a 72-year-old male with severe FXID who underwent a laminoplasty under sufficient, but minimal, FFP transfusion. Through detailed monitoring of activated partial thromboplastin time (APTT) and FXI activity at the perioperative period, we succeeded in hemostatic management of major surgery without significant blood loss and fluid overload...

BACKGROUND: Cervical spondylotic myelopathy (CSM) is the most common cause of cord dysfunction in older individuals. CSM involves either the upper motor neuron or lower motor neuron (LMN) in the cervical spine. The neurological level of the LMN lesion does not usually correspond with the structural level detected via magnetic resonance imaging (MRI) OBJECTIVE: To examine the relationship between the structural level of stenosis and the neurological level of LMN involvement in patients with CSM DESIGN: Retrospective descriptive study SETTING: Tertiary hospital PATIENTS: Patients with cervical spondylotic myelopathy, aged 41 to 79 years METHODS: We reviewed electromyography (EMG) and magnetic resonance imaging (MRI) findings from 17 patients with CSM to objectively show the relationship between the structural level of stenosis and the neurological level with lower motor neuron involvement...

Previous studies have shown compensatory adaptive changes in cerebral functions before surgery in patients with cervical spondylotic myelopathy (CSM), especially in the sensorimotor cortices. However, the structural changes in the sensorimotor cortices in patients with CSM remain poorly understood. The aim of this study was to assess the volumetric changes in the sensorimotor cortices using morphological MRI and to correlate these changes with clinical scales. We hypothesize that CSM causes atrophy in the sensorimotor cortices, which results in functional changes during CSM progression...

Background: Cervical spondylotic myelopathy increases with age, but not all cases are symptomatic. It is usually diagnosed clinically and radiologically (X-ray and magnetic resonance imaging). Surgical treatment is indicated in severe symptomatic cases, while treatment controversy exists in the presence of less severe cases. Anterior and posterior approaches are generally used for decompression with no significant differences in the results of both. Methods: A total of 287 patients of cervical spondylotic myelopathy were treated at our hospital between January 2004 and December 2015...

OBJECTIVE: When treating patients with cervical spondylotic myelopathy (CSM), we often note amelioration in concomitant hypertension after surgery. To assess the effects of surgery and the mechanisms thereof, blood pressure (BP) and parasympathetic nervous activity were monitored prospectively in CSM patients undergoing surgery. METHODS: Sixty-eight consecutive CSM patients who underwent surgery with myoarchitectonic spinolaminoplasty were enrolled. BP and electrocardiography were recorded preoperatively and at 1, 3, and 6 months postoperatively...

BACKGROUND: The pathogenesis of cervical spondylotic myelopathy (CSM) is often multifactorial. Hence, the treatment of this disease requires a differentiated surgical approach in order to adequately address the underlying pathology. PURPOSE: The aim of this review is to identify factors that influence the choice of treatment strategy and to summarize them in an algorithm that serves as a decision aid in choosing the optimal indication for surgical treatment. An attempt is made to define the threshold values for the indication of surgical treatment and to discuss the ideal timing for performing surgery...

STUDY DESIGN: Case-control. OBJECTIVE: The aim of this study was to understand the role of high-resolution magnetic resonance (MR) in identifying regional cord volume loss in cervical spondylotic myelopathy (CSM). SUMMARY OF BACKGROUND DATA: Preliminary studies suggest that compression of the ventral region of the cord may contribute disproportionately to CSM symptomology; however, tract-specific data are lacking in the CSM population. The current study is the first to use 3T MR imaging (MRI) images of CSM patients to determine specific volume loss at the level of detail of individual descending white matter tracts...

Background: Laminoplasty is an established alternative to laminectomy for posterior cervical decompression in spondylotic myelopathy. However, standard laminoplasty requires internal fixation, which is often not obtainable in developing countries. We present our experience with a technique of noninstrumented (floating) laminoplasty developed to avoid the need to anchor the laminoplasty to the anterior elements. Methods: We have used floating laminoplasty (FL) for posterior cervical decompression in patients with cervical spondylosis since 2004 and report the technique and our experience with it between 2009 and 2014 when C-arm and magnetic resonance imaging became available in our unit...

PURPOSE OF REVIEW: The article discusses the current diagnostic and therapeutic approach to myelopathies occurring as a consequence of structural cervical and thoracic spine disease. RECENT FINDINGS: The exact pathophysiologic basis of cervical spondylotic myelopathy remains somewhat elusive. Diffusion-tensor imaging has emerged as a useful imaging modality that correlates more closely with clinical severity than standard MRI. Baseline disease severity, symptom duration, age, presence of impaired gait, and smoking status are significant factors related to surgical outcomes...

Although it is known that aging plays an important role in the incidence and progression of cervical spondylotic myelopathy (CSM), the underlying mechanism is unclear. Studies that used fresh bovine cervical spinal cord report the gray matter of the cervical spinal cord as being more rigid and fragile than the white matter. However, there are no reports regarding the association between aging an tensile and Finite Element Method (FEM). Therefore, FEM was used based on the data pertaining to the mechanical features of older bovine cervical spinal cord to explain the pathogenesis of CSM in elderly patients...
