    Cervical spondylotic myelopathy (CSM) is a common condition. Uninstrumented laminectomy may be complicated by postoperative instability, whereas anterior or posterior decompression with fusion may be associated with stiffness and adjacent segment disease. Cervical laminoplasty, initially oriented towards pediatric patients and ossification of the posterior longitudinal ligament, becomes an interesting surgical alternative to decompress and reconstruct cervical anatomy without fusion. Eighteen patients (12 men, 6 women), mean age 64.2 who presented with CSM were treated surgically using multilevel laminoplasty, and reviewed after 1 month, 6 months, 1 year and 2 years. Clinical evaluation was performed based on the Benzel-JOA and Nurick scores. The preoperative mean Benzel-JOA score was 13.55; Preoperative mean Nurick score was 1.88. Preoperative MRI was carried-out in 16/18 patients. Intramedullary hyperintensity in T2 was observed in 6 patients. The operation was performed on 2 levels (4 patients) 3 levels (11 patients) and 4 levels (3 patients). We used the open-door hinged laminoplasty technique, using metallic implants, without bone graft. At one month FU, mean JOA score was 15.44, and Nurick dropped to 1.05. At 6 months, mean JOA was 16.28 and Nurick was 0.71. At one year, the mean JOA score was 16.16, and Nurick was 0.83. At 2 years, mean JOA was 17.5, and Nurick was 0.25. One infection, one dural tear and one transient episode of C5 paresthesia were observed. We conclude that spinal cord decompression by open-door laminoplasty for CSM allows significant clinical improvement observed progressively in the two years following surgery. PMID:25239380

    Cervical spondylotic myelopathy(CSM) is the most common cause of spinal cord dysfunction and is caused by static or dynamic repeated compression of the spinal cord resulting from degenerative arthritis of the cervical spine and some biological injuries to the cervical spine. The T2 signal change on conventional magnetic resonance imaging(MRI) is most commonly associated with neurological deficits. Diffusion tensor imaging and MR spectroscopy show altered microstructure and biochemistry that reflect patient-specific pathogenesis and can be used to predict neurological outcome and response to intervention. Functional MRI can help to assess the neurological functional recovery after decompression surgery for CSM.

    Full Text Available Background: Noncontiguous cervical spondylotic myelopathy (CSM is a special degenerative disease because of the intermediate normal level or levels between supra and infraabnormal levels. Some controversy exists over the optimal procedure for two noncontiguous levels of CSM. The study was to evaluate the outcomes of the anterior cervical discectomy and fusion (ACDF with zero-profile devices for two noncontiguous levels of CSM. Materials and Methods: 17 consecutive patients with two noncontiguous levels of CSM operated between December 2009 and August 2012 were included in the study. There were 12 men and 5 women with a mean age of 60.7 years (range 45-75 years. Involved disc levels were C3/4 and C5/6 in 11 patients and C4/5 and C6/7 in six patients. Preoperative plain radiographs, computed tomography (CT with 3-D reconstruction and magnetic resonance imaging (MRI of the cervical spine were taken in all patients. All radiographs were independently evaluated by 2 spine surgeons and 1 radiologist. The outcomes were assessed by the average operative time, blood loss, Japanese Orthopedic Association (JOA score, improvement rate, neck dysfunction index (NDI, swallowing quality of life (SWAL-QOL score, the cervical lordosis and complications. Results: The mean followup was 48.59 months (range 24-56 months. The average operative time and blood loss was 105.29 min and 136.47 ml, respectively. The preoperative JOA score was 8.35, which significantly increased to 13.7 at the final followup ( P 0.05. Cerebrospinal fluid leak, dysphagia and radiological adjacent segment degeneration occurred in one patient, respectively. Conclusion: The ACDF with zero-profile devices is generally effective and safe in treating two noncontiguous levels of CSM.

    Although cervical spondylotic myelopathy is a common cause of chronic spinal cord dysfunction in humans, little is known about the molecular mechanisms underlying the progressive neural degeneration characterized by this condition. Based on animal models of cervical spondylotic myelopathy and traumatic spinal cord injury, we hypothesized that Fas-mediated apoptosis and inflammation may play an important role in the pathobiology of human cervical spondylotic myelopathy. We further hypothesized that neutralization of the Fas ligand using a function-blocking antibody would reduce cell death, attenuate inflammation, promote axonal repair and enhance functional neurological outcomes in animal models of cervical spondylotic myelopathy. We examined molecular changes in post-mortem human spinal cord tissue from eight patients with cervical spondylotic myelopathy and four control cases. Complementary studies were conducted using a mouse model of cervical spondylotic myelopathy (twy/twy mice that develop spontaneous cord compression at C2-C3). We observed Fas-mediated apoptosis of neurons and oligodendrocytes and an increase in inflammatory cells in the compressed spinal cords of patients with cervical spondylotic myelopathy. Furthermore, neutralization of Fas ligand with a function-blocking antibody in twy/twy mice reduced neural inflammation at the lesion mediated by macrophages and activated microglia, glial scar formation and caspase-9 activation. It was also associated with increased expression of Bcl-2 and promoted dramatic functional neurological recovery. Our data demonstrate, for the first time in humans, the potential contribution of Fas-mediated cell death and inflammation to the pathobiology of cervical spondylotic myelopathy. Complementary data in a murine model of cervical spondylotic myelopathy further suggest that targeting the Fas death receptor pathway is a viable neuroprotective strategy to attenuate neural degeneration and optimize neurological recovery

  13. Neuropsychological improvement in patients with cervical spondylotic myelopathy after posterior decompression surgery

    International Nuclear Information System (INIS)

    Patients with cervical spondylotic myelopathy sometimes complain of cognitive dysfunction, which may be coincidence. However, cognitive dysfunction may be related to disorders of the cervical spine and/or spinal cord. This study investigated cognitive dysfunction in patients with cervical spinal disorders. A total of 79 patients with cervical spondylotic myelopathy (40 women and 39 men, mean age 61.2 years) underwent cervical laminoplasty between January 2006 and July 2007. Ten of these 79 patients (7 women and 3 men, mean age 65.2 years) complained of moderate to severe memory disturbances. These 10 patients underwent neuroimaging studies and a battery of neuropsychological tests consisting of the mini-mental state examination, Kohs Block Design Test, Miyake Memory Test, Benton Visual Retention Test (BVRT), and 'kana-hiroi' test before and 3 months after surgery. Brain magnetic resonance imaging showed no organic brain lesions in the 10 patients, but single photon emission computed tomography demonstrated reduced regional cerebral blood flow in the posterior cortical areas in eight patients before surgery. Neuropsychological test scores showed statistically significant improvement after surgery in the Kohs Block Design Test and the BVRT, which measure visuospatial perception and reflect the function of the parietal and/or occipital lobes (p<0.05). The practice effect may have contributed to the neuropsychological improvements, but this study suggests that cervical spinal disorders may affect cognitive functions and that surgical treatment can ameliorate such effects.

  14. Multilevel cervical spondylotic myelopathy treated by anterior cervical decompression in subsection and autograft fusion

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Objective:To investigate a novel surgical method for multilevel cervical spondylotic myelopathy (CSM). Methods: Totally 21 patients with multilevel CSM undergoing a novel surgical procedure from April 2001 to January 2004 were analyzed retrospectively. All patients experienced anterior cervical decompression surgery in subsection, autograft fusion and internal fixation. Preoperative, immediate postoperative and follow-up image data, X-rays and semi-quantitative Japanese orthopaedics association (JOA) scores were used to evaluate the restoration of lordosis (Cobb's angle), intervertebral heights, the stability of the cervical spine and the improvement of neurological impairment. Results: Preoperative symptoms were markedly alleviated or disappeared in most of the patients. According to the JOA scores, the ratio of improvement in neurological function was 72.2%, including excellent in 9 cases (42.9%), good in 7 cases (33.3%), fair in 3 cases (14.3%) and poor in 2 cases (9.5%). Immediate postoperative X-rays showed obvious improvements in lordosis and in the intervertebral height of the cervical spine (P<0.01). There is no evidence of instrument failure during the mean follow-up period of 14.2 months (9-24 months, P>0.01). Conclusion:Anterior cervical decompression in subsection, autograft fusion and internal fixation is a rational effective method for the surgical treatment of multilevel CSM.

    Objective: To discuss the correlation between diffusion tensor imaging (DTI) measurements, diffusion tensor tractography and the clinical symptoms of cervical spondylotic myelopathy. Methods: Based on the Japanese Orthopedics Association (JOA) score, 104 cervical spondylotic myelopathy cases were first divided into four groups: mild, moderate, severe and serious groups. According to lesion signal characteristics, all cases were again divided into three groups: A(N/N): normal signal in both T1WI and T2WI; B (N/H): normal signal in T1WI but high signal in T2WI; and C (L/H): low signal in T1WI and high signal in T2WI. The apparent diffusion coefficient (ADC), fractional anisotropy (FA), λ1, λ2, and λ3 were measured and diffusion tensor tractography was performed in the seriously compressed section of the spinal cord. Results: The FA values were positively correlated with JOA scores (r = 0.883, P < 0.05), and significantly different among four JOA groups (P < 0.05). The ADC, λ2, and λ3 were significantly different among the moderate, severe and serious groups as well as among the A, B, and C groups (P < 0.05). Declining FA values were found associated with increasing fiber bundle damage. Conclusions: The FA values and the change patterns of fiber bundle were more sensitive than T2WI for spinal cord lesion, and were positively correlated with clinical symptoms.

    The purpose of this study was to compare the results of 2 surgical strategies for 4-level cervical spondylotic myelopathy: a hybrid procedure using anterior cervical diskectomy and fusion (ACDF) combined with segmental corpectomy versus posterior laminectomy and fixation. Between 2002 and 2010, fifty-one patients with consecutive 4-level cervical spondylotic myelopathy were treated surgically, with 27 patients undergoing the hybrid procedure and 24 undergoing posterior laminectomy and fixation. Radiologic data were compared between the 2 groups, including cervical curvature and cervical range of motion (ROM) in the sagittal plane. Pre- and postoperative neurological status was evaluated using the Japanese Orthopaedic Association (JOA) scoring system and the Nurick grading system. Mean ROM at last follow-up was not significantly different between the 2 groups (P>.05). In the hybrid group, mean JOA score and Nurick grade improved from 9.6±1.4 and 2.74±0.45 respectively, preoperatively, to 13.9±1.3 and 0.86±0.38 respectively, postoperatively. In the fixation group, mean JOA score and Nurick grade improved from 9.4±1.2 and 2.81±0.42 respectively, preoperatively, to 13.1±1.5 and 1.32±0.36 respectively, postoperatively. The JOA scores and Nurick grades at last follow-up were significantly different between the 2 groups (Pcervical kyphosis, preoperative JOA score and Nurick grade were not significantly different between the 2 groups (P>.05); however, JOA scores and Nurick grades at last follow-up showed better improvement in the hybrid group than in the fixation group (Pcervical lordosis, the preoperative and last follow-up JOA score and Nurick grade were not significantly different between the 2 groups (P>.05).

    The primary aim of this study was to conduct a systematic review of reports of patients with cervical spondylotic myelopathy and to assess the value of intraoperative monitoring (IOM), including somatosensory evoked potentials, transcranial motor evoked potentials and electromyography, in anterior cervical procedures. A search was conducted to collect a small database of relevant papers using key words describing disorders and procedures of interest. The database was then shortlisted using selection criteria and data was extracted to identify complications as a result of anterior cervical procedures for cervical spondylotic myelopathy and outcome analysis on a continuous scale. In the 22 studies that matched the screening criteria, only two involved the use of IOM. The average sample size was 173 patients. In procedures done without IOM a mean change in Japanese Orthopaedic Association score of 3.94 points and Nurick score by 1.20 points (both less severe post-operatively) was observed. Within our sub-group analysis, worsening myelopathy and/or quadriplegia was seen in 2.71% of patients for studies without IOM and 0.91% of patients for studies with IOM. Variations persist in the existing literature in the evaluation of complications associated with anterior cervical spinal procedures. Based on the review of published studies, sufficient evidence does not exist to make recommendations regarding the use of different IOM modalities to reduce neurological complications during anterior cervical procedures. However, future studies with objective measures of neurological deficits using a specific IOM modality may establish it as an effective and reliable indicator of injury during such surgeries.

Cervical spondylotic myelopathy (CSM is the most common non-traumatic cause of myelopathy, which displays neurological symptoms and may induce systemic symptoms. To date, it is still unknown whether CSM is associated with hypertension, and if so, whether the decompression operations can attenuate CSM associated hypertension. Here, a total of 309 patients with CSM who received anterior or posterior decompression surgery were enrolled as subjects. Blood pressure measurements were performed before and within one week after the surgery. Among the 309 subjects, 144 (46.6% of them exhibited hypertension before surgery, a significantly higher ratio than that of the whole population. One week after surgery, blood pressure of 106 (73.6% patients turned back to normal. Blood pressure of another 37(25.7% patients decreased with different degrees, although still higher than normal. Moreover, it appears that both approaches were effective in improving blood pressure, while the posterior approach was more effective in decreasing systolic blood pressure. We speculate this type of hypertension might result from hyperactivity of sympathetic nervous system as the heart rate of these patients decreased after surgery as well. Collectively, compression of spinal cord in CSM patients might be associated with hypertension, and decompression surgery largely attenuated this type of hypertension. These findings prove CSM to be a potential associated factor of high blood pressure and may shed light on therapies of hypertension in clinics.

    2015-01-01

    Full Text Available To compare the clinical efficacy and radiological outcome of treating 4-level cervical spondylotic myelopathy (CSM with either anterior cervical discectomy and fusion (ACDF or “skip” corpectomy and fusion, 48 patients with 4-level CSM who had undergone ACDF or SCF at our hospital were analyzed retrospectively between January 2008 and June 2011. Twenty-seven patients received ACDF (Group A and 21 patients received SCF. Japanese Orthopaedic Association (JOA score, Neck Disability Index (NDI score, and Cobb’s angles of the fused segments and C2-7 segments were compared in the two groups. The minimum patient follow-up was 2 years. No significant differences between the groups were found in demographic and baseline disease characteristics, duration of surgery, or follow-up time. Our study demonstrates that there was no significant difference in the clinical efficacy of ACDF and SCF, but ACDF involves less intraoperative blood loss, better cervical spine alignment, and fewer postoperative complications than SCF.

  1. Indication for the operative methods in surgical treatment of cervical spondylotic myelopathy

    International Nuclear Information System (INIS)

    Indication for the operative methods for cervical spondylotic myelopathy was examined in 16 patients undergoing CT-myelography before and after operation. There was a highly significant correlation between the anteroposterior (A-P) diameter of the spinal cord and clinical symptoms. Patients with shorter A-P diameter of the spinal cord tended to have severer preoperative clinical symptoms. Clinical symptoms improved as the post operative A-P diameter of the spinal cord increased. Fixation with decompression of the anterior spinal cord should be indicated when constriction of 5 mm or less of the spinal cord is seen segmentally at the level of the intervertebral disc. Dilation of the spinal cavity should be indicated when the constriction of the spinal cord is 5 mm or less at all levels of the cervical spinal cord. In performing fixation with anterior decompression, 15 mm is considered to be the most suitable width for complete and safe decompression of the flattened spinal cord with a wide transverse diameter.

    Full Text Available BACKGROUND: Results showed good clinical outcomes of anterior corpectomy and fusion (ACCF for patients with cervical spondylotic myelopathy (CSM during a short term follow-up; however, studies assessing long term results are relatively scarce. In this study we intended to assess the long term clinical and radiographic outcomes, find out the factors that may affect the long term clinical outcome and evaluate the incidence of adjacent segment disease (ASD. METHODS: This is a retrospective study of 145 consecutive CSM patients on ACCF treatment with a minimum follow-up of 5 years. Clinical data were collected from medical and operative records. Patients were evaluated by using the Japanese Orthopedic Association (JOA scoring system preoperatively and during the follow-up. X-rays results of cervical spine were obtained from all patients. Correlations between the long term clinical outcome and various factors were also analyzed. FINDINGS: Ninety-three males and fifty-two females completed the follow-up. The mean age at operation was 51.0 years, and the mean follow-up period was 102.1 months. Both postoperative sagittal segmental alignment (SSA and the sagittal alignment of the whole cervical spine (SACS increased significantly in terms of cervical lordosis. The mean increase of JOA was 3.8 ± 1.3 postoperatively, and the overall recovery rate was 62.5%. Logistic regression analysis showed that preoperative duration of symptoms >12 months, high-intensity signal in spinal cord and preoperative JOA score ≤ 9 were important predictors of the fair recovery rate (≤ 50%. Repeated surgery due to ASD was performed in 7 (4.8% cases. CONCLUSIONS: ACCF with anterior plate fixation is a reliable and effective method for treating CSM in terms of JOA score and the recovery rate. The correction of cervical alignment and the repeated surgery rate for ASD are also considered to be satisfactory.

    OBJECTIVE The physiological mechanisms underlying the recovery of motor function after cervical spondylotic myelopathy (CSM) surgery are poorly understood. Neuronal plasticity allows neurons to compensate for injury and disease and to adjust their activities in response to new situations or changes in their environment. Cortical reorganization as well as improvement in corticospinal conduction happens during motor recovery after stroke and spinal cord injury. In this study the authors aimed to understand the cortical changes that occur due to CSM and following CSM surgery and to correlate these changes with functional recovery by using blood oxygen level-dependent (BOLD) functional MRI (fMRI). METHODS Twenty-two patients having symptoms related to cervical cord compression due to spondylotic changes along with 12 age- and sex-matched healthy controls were included in this study. Patients underwent cervical spine MRI and BOLD fMRI at 1 month before surgery (baseline) and 6 months after surgery. RESULTS Five patients were excluded from analysis because of technical problems; thus, 17 patients made up the study cohort. The mean overall modified Japanese Orthopaedic Association score improved in patients following surgery. Mean upper-extremity, lower-extremity, and sensory scores improved significantly. In the preoperative patient group the volume of activation (VOA) was significantly higher than that in controls. The VOA after surgery was reduced as compared with that before surgery, although it remained higher than that in the control group. In the preoperative patient group, activations were noted only in the left precentral gyrus (PrCG). In the postoperative group, activations were seen in the left postcentral gyrus (PoCG), as well as the PrCG and premotor and supplementary motor cortices. In postoperative group, the VOA was higher in both the PrCG and PoCG as compared with those in the control group. CONCLUSIONS There is over-recruitment of sensorimotor cortices

    The aims of this study were to validate a computerised method to detect muscle activity from surface electromyography (SEMG) signals in gait in patients with cervical spondylotic myelopathy (CSM), and to evaluate the test-retest reliability of the activation times designated by this method. SEMG signals were recorded from rectus femoris (RF), biceps femoris (BF), tibialis anterior (TA), and medial gastrocnemius (MG), during gait in 12 participants with CSM on two separate test days. Four computerised activity detection methods, based on the Teager-Kaiser Energy Operator (TKEO), were applied to a subset of signals and compared to visual interpretation of muscle activation. The most accurate method was then applied to all signals for evaluation of test-retest reliability. A detection method based on a combined slope and amplitude threshold showed the highest agreement (87.5%) with visual interpretation. With respect to reliability, the standard error of measurement (SEM) of the timing of RF, TA and MG between test days was 5.5% stride duration or less, while the SEM of BF was 9.4%. The timing parameters of RF, TA and MG designated by this method were considered sufficiently reliable for use in clinical practice, however the reliability of BF was questionable.

    Objective:To observe the clinical effect of anterior decompression and reconstruction using titanium mesh with locking plates in the treatment of cervical spondylotic myelopathy.Methods:One hundred and twenty patients with cervical spondylotic myelopathy were treated by anterior decompression and reconstruction using titanium mesh with locking plates.There were 66 men and 54 women ranges in age from 37 to 72 Years(mean age, 58.3 years).The mean Japanese orthopedic surgery association(JOA) scale was 9.6 points before operation.Patients were followed up clinically and radiographically.Results:Having stood surgery well, the operation time ranged between 60-100 min and bleeding during operation ranged between 20-200 ml.There were no case of postoperative infection, recurrent laryngeal nerve palsy, or esophageal or tracheal laceration or rupture.The average follow-up period was 14.3 months(range, 12 to 24 months) in 96 who were followed up.At the last follow-up visit the mean JOA scale had improved to 14.4 points, reflecting an improve ment of 4.8 points.The results were considered to be excellent in 87 patients, good in 25, fair in 6, and poor in 2.No hardware-related complications or adjacent segment degenerative changes were encountered during the follow-up periods.Stable bone union was observed in all cases and the average time required for fusion was 5.7 months.Conclusion:Titanium mesh filled with autologous bone graft can avoid the complications associated with harvesting bone from the iliac crest donor site.When combined with cervical anterior locking plate, it can obtain satisfatory clinical results for the treatment of cervical spondylotic myelopathy.

  6. Correlation study between 3 T MR DTI measurements and symptoms in patients with cervical spondylotic myelopathy

    International Nuclear Information System (INIS)

    Objective: To evaluate the correlation between diffusion tensor imaging (DTI) measurements,fiber tracking (FT) and the clinical symptoms in patients with cervical spondylotic myelopathy. Methods: According to the Japanese orthopaedics association score (JOA), 104 patients with cervical spondylopathy were divided into 4 groups: mild in 31 patients with 13-16 scores, moderate in 27 with 9-12 scores, severe in 25 with 5-8 scores, and serious in 21 with 0-4 scores. According to the lesion signal characters, all patients were divided into 3 groups: Group A with normal signal in both T1WI and T2WI in 33 patients, Group B with normal signal in T1WI but high signal in T2WI in 30 patients, and Group C with low signal in T1WI and high signal in T2WI in 41 patients. Apparent diffusion coefficient (ADC), fractional anisotropy (FA), λ1, λ2, λ3 were measured in the spinal cord at the serious pressed section,and fiber tractography was performed. The Spearman correlation analyses was used to correlate each of the DTI measurement with JOA score. Group difference was tested with one-way ANOVA method. Results: High quality of DTI was acquired in all patients. The FA values in the mild, moderate,severe, and serious groups were respectively 0.69 ±0.13, 0.58 ±0.03, 0.46 ±0.08, and 0.37 ±0.11 and significant difference was found in different groups (F=100.59, P<0.05) and positively correlated with JOA scores (r=0.883, P<0.05). There was no statistical significance between JOA scores and ADC, λ1, λ2, λ3 (r=0.232, 0.217, 0.113, 0.127, P>0.05). The FA values in group A, B, and C were respectively 0.67 ±0.33, 0.51 ±0.21, 0.38 ±0.03, and significant difference was found among different groups (F=50.05, P<0.05). Decrease of JOA score and high signal in T2 accompanied with decrease of FA value. Decrease of FA values was found associated with increase of fiber bundle damage. The ADC, λ2, λ3 but not λ1 were significantly different among the JOA groups and the group A, B,and C

    Full Text Available Background: To investigate the association between single nucleotide polymorphisms (SNPs of bone morphogenic proteins-4 (BMP-4 gene and the susceptibility of cervical spondylotic myelopathy (CSM and its outcome after surgical treatment. Method: A total of 499 patients with CSM and 602 healthy volunteers were recruited. 425 CSM patients received anterior cervical corpectomy and fusion (ACF and were follow-up until 12 months. The SNPs of BMP-4 were determined. Results: For 6007C > T polymorphism, the cases had a significant lower prevalence of TT genotype than controls. With the CC genotype as reference, the TT genotype carriages significantly influence the CSM risk. The T allele carriage represented a higher risk for CSM as well. The TT of 6007C>T polymorphisms is also associated with higher chance to gain improvement from ACF surgery. The T allele carriage of 6007C>T had markedly higher chance to have a better post-operative outcome compared with C allele carriage. The genotype and allele distributions of -5826G>A polymorphism did not show positive association with risk and outcome of CSM in this study. Conclusion: BMP-4 genetic polymorphisms may be used as a molecular marker for the CSM susceptibility and its postoperative outcome in those underwent surgical treatment.

Therefore, we conducted a meta-analysis to quantitatively compare the efficacy and safety of ACDF and ACCF in the treatment of cervical spondylotic myelopathy.Methods: PubMed, Embase, Web of Science, SinoMed (Chinese BioMedical Literature Service System, People’s Republic of China, and CNKI (China National Knowledge Infrastructure, People’s Republic of China were systematically searched to identify all available studies comparing efficacy and safety between patients receiving ACDF and ACCF. The weighted mean difference (WMD was pooled to compare the Japanese Orthopaedic Association scores, visual analog scale scores, hospital stay, operation time, and blood loss. The risk ratio was pooled to compare the incidence of complications and fusion rate. Pooled estimates were calculated by using a fixed-effects model or a random-effects model according to the heterogeneity among studies.Results: Eighteen studies (17 observational studies and one randomized controlled trial were included in this meta-analysis. Our results suggest that hospital stay (WMD =-1.33, 95% confidence interval [CI]: -2.29, -0.27; P=0.014, operation time (WMD =-26.9, 95% CI: -46.13, -7.67; P=0.006, blood loss (WMD =-119.36, 95% CI: -166.94, -71.77; P=0.000, and incidence of complications (risk ratio =0.51, 95% CI: 0.33, 0.80; P=0.003 in the ACDF group were significantly less than that in the ACCF group.

  12. The correlation between evoked spinal cord potentials and magnetic resonance imaging before Surgery in cervical spondylotic myelopathy

    International Nuclear Information System (INIS)

    The purpose of this study is to clarify the correlation between electrophysiological examination and MRI diagnosis. Twenty-four patients with cervical spondylotic myelopathy were examined with magnetic resonance imaging and evoked spinal cord potentials (ESCPs) before surgery. In all the patients, only the intervertebral level was symptomatic, as shown by ESCPs. ESCPs following median nerve stimulation (MN-ESCPs), transcranial electric stimulation (TCE-ESCPs), and spinal cord stimulation (Spinal-ECSPs) were recorded. The patients were grouped into two groups as follows: group A, all ESCPs were abnormal; group B, normal spinal cord stimulation. Spinal cord transverse area and compression ratio (central and 1/4-lateral anteroposterior diameter divided by transverse diameter) were measured on T1-weighted axial imaging, with abnormal ESCPs as indicators of spinal cord morphology. Central and 1/4-lateral compression ratio was significantly lower in group A. Spinal cord morphology of magnetic resonance imaging is useful for functional diagnosis. (author)

    Full Text Available Background: Posterior cervical decompression is an accepted treatment for multilevel cervical spondylotic myelopathy (CSM. Each posterior technique has its own advantages and disadvantages. In the present study, we compared the functional and radiological outcomes of expansive hemilaminectomy and laminoplasty with mini titanium plate in the treatment of multilevel CSM. Methods: Forty-four patients with multilevel CSM treated with posterior cervical surgery in Department of Orthopedic Surgery, Beijing Army General Hospital from March 2011 to June 2012 were enrolled in this retrospective study. Patients were divided into two groups by surgical procedure: Laminoplasty (Group L and hemilaminectomy (Group H. Perioperative parameters including age, sex, duration of symptoms, operative duration, and intraoperative blood loss were recorded and compared. Spinal canal area, calculated using AutoCAD ® software(Autodesk Inc., San Rafael, CA, USA, and neurological improvement, evaluated with Japanese Orthopedic Association score, were also compared. Results: Neurological improvement did not differ significantly between groups. Group H had a significantly shorter operative duration and significantly less blood loss. Mean expansion ratio was significantly greater in Group L (77.83 ± 6.41% than in Group H (62.72 ± 3.86% (P < 0.01. Conclusions: Both surgical approaches are safe and effective in treating multilevel CSM. Laminoplasty provides a greater degree of enlargement of the spinal canal, whereas expansive hemilaminectomy has the advantages of shorter operative duration and less intraoperative blood loss.

    Full Text Available OBJECT: The concept of minimum clinically important difference (MCID has been used to measure the threshold by which the effect of a specific treatment can be considered clinically meaningful. MCID has previously been studied in surgical patients, however few studies have assessed its role in spinal surgery. The goal of this study was to assess the role of MCID in patients undergoing anterior cervical discectomy and fusion (ACDF for cervical spondylotic myelopathy (CSM. METHODS: Data was collected on 30 patients who underwent ACDF for CSM between 2007 and 2012. Preoperative and 1-year postoperative Neck Disability Index (NDI, Visual-Analog Scale (VAS, and Short Form-36 (SF-36 Physical (PCS and Mental (MCS Component Summary PRO scores were collected. Five distribution- and anchor-based approaches were used to calculate MCID threshold values average change, change difference, receiver operating characteristic curve (ROC, minimum detectable change (MDC and standard error of measurement (SEM. The Health Transition Item of the SF-36 (HTI was used as an external anchor. RESULTS: Patients had a significant improvement in all mean physical PRO scores postoperatively (p<0.01 NDI (29.24 to 14.82, VAS (5.06 to 1.72, and PCS (36.98 to 44.22. The five MCID approaches yielded a range of values for each PRO: 2.00-8.78 for PCS, 2.06-5.73 for MCS, 4.83-13.39 for NDI, and 0.36-3.11 for VAS. PCS was the most representative PRO measure, presenting the greatest area under the ROC curve (0.94. MDC values were not affected by the choice of anchor and their threshold of improvement was statistically greater than the chance of error from unimproved patients. CONCLUSION: SF-36 PCS was the most representative PRO measure. MDC appears to be the most appropriate MCID method. When MDC was applied together with HTI anchor, the MCID thresholds were: 13.39 for NDI, 3.11 for VAS, 5.56 for PCS and 5.73 for MCS.

    2013-08-01

    Cervical spondylotic myelopathy (CSM) is a common disorder involving chronic progressive compression of the cervical spinal cord due to degenerative disc disease, spondylosis, or other degenerative pathology. CSM is the most common form of spinal cord impairment and causes functional decline leading to reduced independence and quality of life. Despite a sound understanding of the disease process, clinical presentation and management, a universal definition of CSM and a standardized index of severity are not currently used universally. Work is required to develop a definition and establish clinical predictors of progression to improve management of CSM. Despite advances in decompressive and reconstructive surgery, patients are often left with residual disability. Gaps in knowledge of the pathobiology of CSM have limited therapeutic advances to complement surgery. Although the histopathologic and pathophysiologic similarities between CSM and traumatic spinal cord injury have long been acknowledged, the unique pathomechanisms of CSM remain unexplored. Increased efforts to elucidate CSM pathobiology could lead to the discovery of novel therapeutic targets for human CSM and other spinal cord diseases. Here, the natural history of CSM, epidemiology, clinical presentation, and current methods of clinical management are reported, along with the current state of basic scientific research in the field.

    2016-01-01

    Objective: To analyze and compare the clinical efficacy of anterior and posterior decompression in the treatment of multi-segmental cervical spondylotic myelopathy (MCSM), providing certain guidance for the clinical treatment. Methods:A total of 72 patients with MCSM who were admitted in our hospital from September, 2012 to October, 2014 were included in the study and divided into the anterior group (n=37) and the posterior group (n=35) according to different surgical methods. The patients in the anterior group were given anterior cervical discectomy fusion (ACDF) and anterior cervical corpectomy fusion (ACCF), while the patients in the posterior group were given laminoplasty (LP). The general materials, surgical materials, and postoperative functional recovery in the two groups were compared. Results:The comparison of gender, age, course, preoperative JOA score, follow-up time, and affected segment between the two groups was not statistically significant. The operation time in the anterior group was significantly longer than that in the posterior group, but the intraoperative amount of bleeding was significantly less than that in the posterior group. The postoperative spinal cord function in the two groups was significantly improved when compared with before operation;moreover, the improved degree in the anterior group was more obvious. The postoperative cervical physiological curvature in the anterior group was significantly increased, but in the posterior group was significantly reduced. The comparison of the occurrence rate of postoperative complications between the two groups was not statistically significant. Conclusions:The anterior and posterior surgeries in the treatment of MCSM can significantly improve the postoperative spinal cord function, among which the anterior surgery can effectively recover the cervical physiological curvature. It is recommended that an appropriate surgical method should be reasonably selected by comprehensively considering the

  19. The role of DTI in early detection of cervical spondylotic myelopathy: a preliminary study with 3-T MRI

    International Nuclear Information System (INIS)

    The radiological diagnosis of cervical spondylotic myelopathy (CSM) has to be made as soon as possible, since surgery performed in earlier stages during the course of CSM was reported to be more successful when compared with later stages. We hypothesized that diffusion tensor imaging (DTI) may detect CSM in earlier stages, before the appearance of signal increase in T2-weighted sequences. A total of 16 patients with neurological signs and symptoms of CSM but without hyperintensity in spinal cord on T2-weighted sequences enrolled in the study. The magnetic resonance (MR) examinations were performed on a 3-T MR imaging system. Apparent diffusion coefficient (ADC) and fractional anisotropy (FA) maps were generated on axial plane. The ADC and FA measurements in each individual were made at the level of most severe cervical canal stenosis and at a nonstenotic level. Student's t test was used to compare FA and ADC values of the spinal cord in stenotic and nonstenotic segments. We also investigated if there was a correlation between DTI parametrics and duration of clinical symptoms by using Pearson correlation analysis. All patients showed changes in DTI parametrics at stenotic segments. While FA values of the spinal cord at the stenotic level showed a statistically significant reduction, there was a statistically significant increase in the measured ADC values (p < 0.001). There was no statistical correlation between the duration of symptoms and DTI parametrics. Our preliminary findings indicate that DTI may show abnormalities in the spinal cord before the development of T2 hyperintensity on conventional sequences in patients with CSM. (orig.)

    Prolonged length of stay (PLOS) has been associated with increased hospital resource utilization and worsened patient outcomes in multiple studies. In this study, we defined and identified factors associated with PLOS after posterior surgery for cervical spondylotic myelopathy in patients over the age of 65. PLOS was defined as length of stay beyond the "prolongation point" (that is, the day after which discharge rates begin to decline). Using the United States Nationwide Inpatient Sample database, 2742 patients met inclusion criteria, out of whom 16.5% experienced PLOS (stay beyond 6days). After multivariate analysis, increasing age was independently associated with PLOS (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.02-1.06). Multiple comorbid conditions were associated with PLOS, including alcohol abuse (OR 3.85, 95% CI 1.87-7.94), congestive heart failure (OR 1.72, 95% CI 1.11-2.64), obesity (OR 1.70, 95% CI 1.14-2.55), and deficiency anemia (OR 1.44, 95% CI 1.01-2.05); the strongest associated operative parameter was blood transfusion (OR 2.39, 95% CI 1.75-3.28). Major complications independently associated with PLOS were deep vein thrombosis (OR 18.32, 95% CI 6.50-51.61), myocardial infarction (OR 8.98, 95% CI 2.92-27.56), pneumonia (OR 6.67, 95% CI 3.17-14.05), acute respiratory failure (OR 6.27, 95% CI 3.43-11.45), hemorrhage/hematoma (OR 5.04, 95% CI 2.69-9.44), and implant-related complications (OR 2.49, 95% CI 1.24-4.98). Average total hospital charges for patients who experienced PLOS were $122,965 US dollars, compared to $76,870 for the control group (p<0.001). Mortality for patients who experienced PLOS was 2.7% versus 0.5% for patients who did not epxerience PLOS (p<0.001). In conclusion, patients over the age of 65 who underwent posterior surgery for cervical myelopathy and stayed over 6days in hospital were defined as having PLOS. Hospital charges and mortality rates were significantly higher for patients who experienced PLOS. Potentially

    To assess the long-term clinical and radiographic outcomes of anterior cervical corpectomy and fusion (ACCF) with a neotype nano-hydroxyapatite/polyamide 66 (n-HA/PA66) strut in the treatment of cervical spondylotic myelopathy (CSM). Fifty patients with CSM who underwent 1- or 2-level ACCF with n-HA/PA66 struts were retrospectively investigated. With a mean follow-up of 79.6 months, the overall mean JOA score, VAS and cervical alignment were improved significantly. At last follow-up, the fusion rate was 98%, and the subsidence rate of the n-HA/PA66 strut was 8%. The “radiolucent gap” at the interface between the n-HA/PA66 strut and the vertebra was further noted to evaluate the osteoconductivity and osseointegration of the strut, and the incidence of it was 62% at the last follow-up. Three patients suffered symptomatic adjacent segment degeneration (ASD). No significant difference was detected in the outcomes between 1- and 2-level corpectomy at follow-ups. In conclusion, the satisfactory outcomes in this study indicated that the n-HA/PA66 strut was an effective graft for cervical reconstruction. Moreover, the osteoconductivity and osseointegration of the strut is still need to be optimized for future clinical application owing to the notably presence of “radiolucent gap” in present study.

    Full Text Available The optimal surgical treatment for multilevel cervical spondylotic myelopathy (MCSM remains controversial. This study compared the outcomes of three surgical approaches for MSCM treatment, focusing on the efficacy and safety of a combined approach.This retrospective study included 153 consecutive MCSM patients (100 men, 53 women; mean age ± standard deviation, 55.7 ± 9.4 years undergoing operations involving ≥3 intervertebral segments. The patients were divided into three groups according to surgical approach: anterior (n = 19, posterior (n = 76, and combined (n = 58. We assessed demographic variables, perioperative parameters, and clinical outcomes ≥12 months after surgery (20.5 ± 7.6 months, including Japanese Orthopaedic Association (JOA score, improvement, recovery rate, and complications.The anterior group had the most favorable preoperative conditions, including the highest preoperative JOA score (12.95 ± 1.86, p = 0.046. In contrast, the combined group had the highest occupancy ratio (48.0% ± 11.6%, p = 0.002. All groups showed significant neurological improvement at final follow-ups, with JOA recovery rates of 59.7%, 54.6%, and 68.9% in the anterior, posterior, and combined groups, respectively (p = 0.163. After multivariable adjustments, the groups did not have significantly different clinical outcomes (postoperative JOA score, p = 0.424; improvement, p = 0.424; recovery rate, p = 0.080. Further, subgroup analyses of patients with occupancy ratios ≥50% showed similar functional outcomes following the posterior and combined approaches. Overall complication rates did not differ significantly among the three approaches (p = 0.600. Occupancy ratios did not have a significant negative influence on postoperative recovery following the posterior approach.If applied appropriately, all three approaches are effective for treating MCSM. All three approaches had equivalent neurological outcomes, even in subgroups with high occupancy

    Objectives Cervical disc arthroplasty (CDA) with Discover prosthesis or anterior cervical discectomy and fusion (ACDF) with Zero-P cage has been widely used in the treatment of cervical spondylotic myelopathy (CSM). However, little is known about the comparison of the 2 zero-profile implants in the treatment of single-level CSM. The aim was to compare the clinical outcomes and radiographic parameters of CDA with Discover prosthesis and ACDF with Zero-P cage for the treatment of single-level CSM. Methods A total of 128 consecutive patients who underwent 1-level CDA with Discover prosthesis or ACDF with Zero-P cage for single-level CSM between September 2009 and December 2012 were included in this study. Clinical outcomes were evaluated using the Japanese Orthopaedic Association (JOA) score and Neck Disability Index (NDI). For radiographic assessment, the overall sagittal alignment (OSA), functional spinal unit (FSU) angle, and range of motion (ROM) at the index and adjacent levels were measured before and after surgery. Additionally, the complications were also recorded. Results Both treatments significantly improved all clinical parameters (P 0.05). Besides, no significant differences existed in dysphagia, subsidence, or adjacent disc degeneration between the 2 groups (P > 0.05). However, significant differences occurred in prosthesis migration in CDA group. Conclusions The results of this study showed that clinical outcomes and radiographic parameters were satisfactory and comparable with the 2 techniques. However, more attention to prosthesis migration of artificial cervical disc should be paid in the postoperative early-term follow-up. PMID:27441736

    Full Text Available The dropped head syndrome (DHS is a disabling condition caused by severe weakness of the neck extensor muscles causing progressive reducible kyphosis of the cervical spine and the inability to hold the head up. Weakness can occur in isolation or in association with a generalized neuromuscular disorder. Isolated cases are owed to the late onset of noninflammatory myopathy designated as INEM, where persistent chin to chest deformity may gradually cause or aggravate preexisting degenerative changes of the cervical spine and ultimately result in myelopathy. In review of the literature, we could find only 5 cases, with no unique guidelines to address the management of these two concomitant pathologies. Herein, a 69-year-old man who had developed cervical myelopathy 2 years after being affected by isolated dropped head syndrome is presented. Chin to chest deformity and cervical myelopathy were managed through three-level anterior cervical discectomy and fusion (ACDF combined with decompressive cervical laminectomy and stabilization with C2 to C7 pedicle screw-rod construct. At 4-month follow-up, despite recovery in patient’s neurological status, flexion deformity reappeared with recurrence of dropped head due to C7 pedicle screws pull-out. However, this was successfully managed with extension of the construct to the upper thoracic levels.

    Non-traumatic spinal cord pathology is responsible for 25-52% of all spinal cord lesions. Studies have revealed that spinal stenosis accounts for 16-21% of spinal cord injury (SCI) admissions. Impaired grips as well as slow unskilled hand and finger movements are the most common complaints in patients with spinal cord disorders, such as myelopathy secondary to cervical spondylosis. In the past, our team carried out couple of successful clinical trials, including two randomized control trials, showing that functional electrical stimulation therapy (FEST) can restore voluntary reaching and/or grasping function, in people with stroke and traumatic SCI. Motivated by this success, we decided to examine changes in the upper limb function following FEST in a patient who suffered loss of hand function due to myelopathy secondary to cervical spondylosis. The participant was a 61-year-old male who had C3-C7 posterior laminectomy and instrumented fusion for cervical myelopathy. The participant presented with progressive right hand weakness that resulted in his inability to voluntarily open and close the hand and to manipulate objects unilaterally with his right hand. The participant was enrolled in the study ~22 months following initial surgical intervention. Participant was assessed using Toronto Rehabilitation Institute's Hand Function Test (TRI-HFT), Action Research Arm Test (ARAT), Functional Independence Measure (FIM), and Spinal Cord Independence Measure (SCIM). The pre-post differences in scores on all measures clearly demonstrated improvement in voluntary hand function following 15 1-h FEST sessions. The changes observed were meaningful and have resulted in substantial improvement in performance of activities of daily living. These results provide preliminary evidence that FEST has a potential to improve upper limb function in patients with non-traumatic SCI, such as myelopathy secondary to cervical spondylosis.

    Indication for the operative methods for cervical spondylotic myelopathy was examined in 16 patients undergoing CT-myelography before and after operation. There was a highly significant correlation between the anteroposterior (A-P) diameter of the spinal cord and clinical symptoms. Patients with shorter A-P diameter of the spinal cord tended to have severer preoperative clinical symptoms. Clinical symptoms improved as the post operative A-P diameter of the spinal cord increased. Fixation with decompression of the anterior spinal cord should be indicated when constriction of 5 mm or less of the spinal cord is seen segmentally at the level of the intervertebral disc. Dilation of the spinal cavity should be indicated when the constriction of the spinal cord is 5 mm or less at all levels of the cervical spinal cord. In performing fixation with anterior decompression, 15 mm is considered to be the most suitable width for complete and safe decompression of the flattened spinal cord with a wide transverse diameter.

    Study Design Cross-sectional. Purpose Clinical outcome study comparing the Copenhagen Neck Functional Disability Scale (CNFDS) and modified Japanese orthopedic association (mJOA) assessment scales in patients with cervical spondylotic myelopathy (CSM). Overview of Literature Comparison of instruments that measure patient-reported outcomes is needed. Methods A cross-sectional analysis was conducted. Ninety five patients with CSM were entered into the study and completed the CNFDS and the mJOA preoperatively and postoperatively. Correlation between the CNFDS and the mJOA was evaluated preoperatively and at the end of follow-up. Responsiveness to change of CNFDS and mJOA was also assessed. Clinical outcomes were also measured with the recovery rate of mJOA score at end of follow-up. Results The mean age of patients was 58.2 (standard deviation, SD=8.7) years. Mean follow-up was 2.1 years (range, 1 to 4 years). The mJOA correlated strongly with the CNFDS score preoperatively and postoperatively (r=–0.81 and –0.82, respectively; p<0.001). The CNFDS and the mJOA were able to detect changes after the surgery (p<0.001). The mean mJOA recovery rate was 51.8% (SD=13.1%). Conclusions Surgery for the treatment of patients with CSM is an efficacious procedure. CNFDS and mJOA scores have a strong correlation in measuring disability among CSM patients. PMID:27340528

    Cervical spondylotic myelopathy (CSM) is the most common cause of spinal cord impairment worldwide and is a risk factor for traumatic central cord syndrome. Despite advances in surgery, there are no effective neuroprotective treatments for CSM, which reflects a limited understanding of its pathophysiology. In order to develop therapeutic strategies, we have developed a novel rat model of chronic progressive cervical spinal cord compression that mimics CSM. A titanium-screw-based chronic compression device (CCD) was designed to achieve progressive cord compression at the C6 level. The CCD was fixed to the C2 and T2 spinous processes and a threaded screw was turned to induce compression. Sprague-Dawley rats (n=75) were divided into three groups: (1) sham (no compression, n=6), (2) mild compression (1.4 mm stenosis, n=27), and (3) severe compression (2.6 mm stenosis, n=42). Compression was evaluated using micro-computed tomography (micro-CT). The area of spared white matter, extent of cord flattening ratio, and loss of neurons were assessed. Functional deficits were characterized using sensory-evoked potential (SEP) recordings, and with neurobehavioral tests: the Basso, Beattie, and Bresnahan (BBB) locomotor rating scale, inclined plane, paw grip strength, and assessment of mechanical and thermal allodynia. Micro-CT confirmed progressive canal stenosis. The loss of intact white matter and cord flattening were significantly greater in rats with severe cord compression, and the number of neurons was reduced at the epicenter of cord compression. With chronic cord compression there was a significant decline in locomotor function, forelimb function, trunk stability/coordination, an increase in mechanical allodynia, and impaired axonal conduction. The CCD model results in chronic and precise cervical cord compression. The compression is associated with mechanical allodynia and measurable neurobehavioral, neurophysiological, and neuropathological deficits. We anticipate

    Keegan (1965) reported a patient who presented with "dissociated motor loss," an acute paralysis of the upper extremity with minimal sensory signs and no long tract signs, and documented an anterior root lesion following autopsy. Sobue et al. (1975) reported similar cases using the term "cervical spondylotic amyotrophy (CSA)," but postulated pathology of the anterior horn. Although Keegan's "dissociated motor loss" surely referred to isolated motor paresis with no or minimal sensory signs, contrary to existing criticism, a more general term, CSA, should be preferred. CSA is divided into proximal and distal types. Distal CSA often presents with a drop finger, and thus may be misdiagnosed as posterior interosseous nerve palsy. Documentation of the involvement of ulnar muscles by clinical signs and EMG would lead to the diagnosis of distal CSA. Proximal CSA may be confused with neuralgic amyotrophy (NA), although the sparing of the serratus anterior and the stereotypic involvement of deltoid, infraspinatus, biceps brachii, and brachioradialis suggest CSA. Cervical MRI is not diagnostic in around half of CSA cases, and denervation in paraspinal EMG is a more sensitive test that can exclude NA. Amyotrophic lateral sclerosis is another important differential diagnosis for CSA. PMID:27156504

    OBJECTIVE This study aimed to estimate the risk of spinal cord injury (SCI) in patients with cervical spondylotic myelopathy (CSM) with and without ossification of posterior longitudinal ligament (OPLL). Also, the study compared the incidence rates of SCI in patients who were managed surgically and conservatively. METHODS This retrospective cohort study covering 15 years analyzed the incidence of SCI in patients with CSM. All patients, identified from the National Health Insurance Research Database, were hospitalized with the diagnosis of CSM and followed up during the study period. These patients with CSM were categorized into 4 groups according to whether they had OPLL or not and whether they received surgery or not: 1) surgically managed CSM without OPLL; 2) conservatively managed CSM without OPLL; 3) surgically managed CSM with OPLL; and 4) conservatively managed CSM with OPLL. The incidence rates of subsequent SCI in each group during follow-up were then compared. Kaplan-Meier and Cox regression analyses were performed to compare the risk of SCI between the groups. RESULTS Between January 1, 1999, and December 31, 2013, there were 17,258 patients with CSM who were followed up for 89,003.78 person-years. The overall incidence of SCI in these patients with CSM was 2.022 per 1000 person-years. Patients who had CSM with OPLL and were conservatively managed had the highest incidence of SCI, at 4.11 per 1000 person-years. Patients who had CSM with OPLL and were surgically managed had a lower incidence of SCI, at 3.69 per 1000 person-years. Patients who had CSM without OPLL and were conservatively managed had an even lower incidence of SCI, at 2.41 per 1000 person-years. Patients who had CSM without OPLL and were surgically managed had the lowest incidence of SCI, at 1.31 per 1000 person-years. The Cox regression model demonstrated that SCIs are significantly more likely to happen in male patients and in those with OPLL (HR 2.00 and 2.24, p risk for approximately 50

    Cervical myelopathy is the most common cause of acquired spinal cord compromise. The concept of degenerative cervical myelopathy (DCM), defined as symptomatic myelopathy associated with degenerative arthropathic changes in the spine axis, is being introduced. Given its progressive nature, treatment options have to be chosen in a timely manner. Surgical options include anterior discectomy and fusion (ACDF), anterior corpectomy and fusion (ACCF), arthroplasty (in highly select cases), posterior laminectomy with/without fusion, and laminoplasty. Indications for each should be carefully considered in individual patients. Riluzole, a sodium-glutamate antagonist, is a promising option to optimize neurologic outcomes post-surgery and is being examined in the CSM-Protect Randomized Controlled Trial. Preoperative risk assessment is mandatory for prognostication. Sagittal alignment is known to play an important role to optimize surgical outcome. Guidelines for optimal management of DCM are in process. In principle, all but the mildest cases of DCM should be offered surgery for optimal outcome. PMID:27250040

    Aim To study the inflammatory mechanism of herniatedcervical intervertebral discs from patients with cervical spondyloticmyelopathy, and the roles of the inflammation in the cervical disc degenera-tion and cervical spondylosis. Methods 35 herniated cervical discs wereobtained fron 31 patients with cervical spondylotic myeloyathy during theanterior cervical surgery. 7 normal, nondegenerated cervical discs(controlgroup) were obtained from three fresh cadavers. All discs were divided intotwo samples, one of which was used as histological examination, and theother was used to detect contents of IL-1α. IL-6 and TNF-α biochemi-cally. Results In 35 herniated cervical discs, 18(51% ) were shownabundant inflammatory cell infiltrates in margin of herniated discs; 17(49%) no inflammatory cell infiltrates; normal discs also no any inflam-matory cell infiltrates. Biochemical assay indicated IL-1 α, IL-6 and TNF-αin cervical spondylotic myelopathy was (10.4 ± 1.9), (7.7 ± 2. 1 ) and(7.5 ± 1.7) pg/g respectively and those in noninflammatory infiltrates groupwas (10.2 ± 1.6), (6.7 ± 2.6) and (7.0 ± 1.8) pg/g respectively and thosein the control group was (2.0±0.9), (1.2±1.0) and (1.3±0.8)pg/g.The contents of cytokine IL-1α, IL-6 and TNF-α were obviously higher thanthat of normal discs( P =0. 000 1, t = 11. 359 1, 7. 951 0, 9. 372 8), andthere were no differences in the contents of cytokines between discs withinflammatory cell infiltrates and discs with no inflammatory cell infiltrates(P> 0.05, t=0.6120, 2.6204, 1.7394).Conelusion Herniatedcervical disc from the cervical spondylotic myelopathy was inflammatory, andinflammation may play an important role in cervical disc degeneration and inpathogenesis of cervical spondylosis.%目的研究颈椎病发生中突出颈椎间盘组织的炎症反应机制及其在颈椎间盘退行性变和颈椎病发病中的作用.方法临床收集了31例脊髓型颈椎病患者的35个突出的颈椎间盘标本和3

    Full Text Available OBJECTIVE: To retrospectively compare the efficacy of the titanium mesh cage (TMC and the nano-hydroxyapatite/polyamide66 cage (n-HA/PA66 cage for 1- or 2-level anterior cervical corpectomy and fusion (ACCF to treat multilevel cervical spondylotic myelopathy (MCSM. METHODS: A total of 117 consecutive patients with MCSM who underwent 1- or 2-level ACCF using a TMC or an n-HA/PA66 cage were studied retrospectively at a mean follow-up of 45.28 ± 12.83 months. The patients were divided into four groups according to the level of corpectomy (1- or 2-level corpectomy and cage type used (TMC or n-HA/PA66 cage. Clinical and radiological parameters were used to evaluate outcomes. RESULTS: At the one-year follow-up, the fusion rate in the n-HA/PA66 group was higher, albeit non-significantly, than that in the TMC group for both 1- and 2-level ACCF, but the fusion rates of the procedures were almost equal at the final follow-up. The incidence of cage subsidence at the final follow-up was significantly higher in the TMC group than in the n-HA/PA66 group for the 1-level ACCF (24% vs. 4%, p = 0.01, and the difference was greater for the 2-level ACCF between the TMC group and the n-HA/PA66 group (38% vs. 5%, p = 0.01. Meanwhile, a much greater loss of fused height was observed in the TMC group compared with the n-HA/PA66 group for both the 1- and 2-level ACCF. All four groups demonstrated increases in C2-C7 Cobb angle and JOA scores and decreases in VAS at the final follow-up compared with preoperative values. CONCLUSION: The lower incidence of cage subsidence, better maintenance of the height of the fused segment and similar excellent bony fusion indicate that the n-HA/PA66 cage may be a superior alternative to the TMC for cervical reconstruction after cervical corpectomy, in particular for 2-level ACCF.

  9. Myelopathy hand in cervical radiculopathy

    International Nuclear Information System (INIS)

    The so-called 'myelopathy hand', or characteristic finger paralysis, often recognized in cervical compression myelopathy, has been considered a unique manifestation of cervical myelopathy. We used our original grip and release test, a 15-second test in which finger motion is captured with a digital camera, to investigate whether cervical radiculopathy has the same characteristics as myelopathy hand. Thirty patients with pure radiculopathy, id est (i.e.), who had radiating arm pain and evidence of corresponding nerve root impingement on X-ray images or MRI scans, but did not have spinal cord compression, served as the subjects. In contrast to other radiculopathies, C7 radiculopathy was manifested by a significant reduction in the number of finger motion cycles on the affected side in comparison with the unaffected side, the same as in myelopathy hand. Uncoordinated finger motion was significantly more frequent on the affected side in C6 radiculopathy than on the unaffected side. These findings contradict the conventional notion that myelopathy hand is a unique manifestation of cervical myelopathy, but some radiculopathies manifested the same kinds of finger paralysis observed in myelopathy hand.

Methods This study involved the patients with multilevel cervical spondylotic myeiopathy who underwent expansive open-door laminoplasty between May 2001 and December 2006. They were classified into two groups according to the degree of neurological recovery: an excellent recovery group (group A), the recovery rotes greater than 75%, and a poor recovery group (group B), the recovery rates lower than 25%. Comparisons of various preoperative clinical and imaging parameters such as patient's age, gender, duration between symptom onset and surgery, follow-up time, preoperative JOA score, preoperative range of motion (ROM), preoperative cervical curvature index(CCI), preoperative Pavlov ratio, segments of myelopathy and so on, revealed that the mean age and mean preoperative JOA scores were significantly different. The cases with the age older than 60 years and preoperative JOA scores less than 6 were excluded. Therefore, group A re-mained 24 cases (group A1) and group B 18 cases (group B1). The same analyses were repeated between group A1 and group B1. There was no significant difference between two groups among the above mentioned parameters. Postoperative ROM and its reduction rate, postoperative CCI and its reduction rate, Pavlov ratio and its increasing rate were analyzed by t test, and the relationship between these six parameters and im-proving rate of JOA scores were also analyzed. Results Except postoperative ROM, other five indexes were statistical differences between A1 and B1 groups. Except postoperative ROM in group A1 and postoperative ROM and its reduction rate in group B1, other indexes had statistical correlation with improving rate of post-operative JOA scores.

    The aim of the study was to analyse the risk of symptomatic myelopathy after minor trauma in patients with asymptomatic spondylotic cervical spinal cord encroachment (ASCCE). In a cohort of 199 patients with ASCCE, previously followed prospectively in a study investigating progression into symptomatic myelopathy, the authors looked retrospectively for traumatic episodes that may have involved injury to the cervical spine. A questionnaire and data file analysis were employed to highlight whatever hypothetical relationship might emerge with the development of symptomatic myelopathy. Fourteen traumatic episodes in the course of a follow-up of 44 months (median) were recorded in our group (who had been instructed to avoid risky activities), with no significant association with the development of symptomatic myelopathy (found in 45 cases). Only three minor traumatic events without fracture of the cervical spine were found among the symptomatic myelopathy cases, with no chronological relationship between trauma and myelopathy. Furthermore, 56 traumatic spinal cord events were found before the diagnosis of cervical cord encroachment was established, with no correlation to either type of compression (discogenic vs osteophytic). In conclusion, the risk of spinal cord injury after minor trauma of the cervical spine in patients with ASCCE appeared to be low in our cohort provided risky activities in these individuals are restricted. Implementation of preventive surgical decompression surgery into clinical practice in these individuals should be postponed until better-designed studies provide proof enough for it to take precedence over a conservative approach.

  1. Cervical myelopathy: magnetic imaging findings

    International Nuclear Information System (INIS)

    69 patients with clinical signs of cervical myelopathy were examined using magnetic imaging (T1- and T2-suspended tomograms of the sagittal and transverse section using a device with 0.04 T field intensity). Vertebral disk hernias were revealed in 35 patients, compression of the spinal cord with metastases into vertebral body in 2, extramedullary tumor in 11, intramedullary tumor in 9, and syringomyelia in 12 patients. T2-suspended tomograms proved to be more informative due to their higher sensitivity to aqueous content. T1-suspended tomograms help assess the degree of spinal cord compression and the direction of the disk protrusion. Magnetic imaging is an informative method used for objective identification of the cases of myelopathy of cervical localization

    Full Text Available Objective: Cervical laminectomies with transpedicular insertion technique is known to be a biomechanically stronger method in cervical pathologies. However, its frequency of use is low in the routine practice, as the pedicle is thin and risk of neurovascular damage is high. In this study, we emphasize the results of cervical laminectomies with transpedicular fixation using fluoroscopy in degenerative cervical spine disorder. Materials and Methods: Postoperative malposition of the transpedicular screws of the 70 pedicles of the 10 patients we operated due to degenerative stenosis in the cervical region, were investigated. Fixation was performed between C3 and C7, and we used resected lamina bone chips for fusion. Clinical indicators included age, gender, neurologic status, surgical indication, and number of levels stabilized. Dominant vertebral artery of all the patients was evaluated with Doppler ultrasonography. Preoperative and postoperative Nurick grade of each patient was documented. Results: No patients experienced neurovascular injury as a result of pedicle screw placement. Two patients had screw malposition, which did not require reoperation due to minor breaking. Most patients had 32-mm screws placed. Postoperative computed tomography scanning showed no compromise of the foramen transversarium. A total of 70 pedicle screws were placed. Good bony fusion was observed in all patients. At follow-up, 9/10 (90% patients had improved in their Nurick grades. The cases were followed-up for an average of 35.7 months (30-37 months. Conclusions: Use of the cervical pedicular fixation (CPF provides a very strong three-column stabilization but also carries vascular injury without nerve damage. Laminectomies technique may reduce the risk of malposition due to visualization of the spinal canal. CPF can be performed in a one-stage posterior procedure. This technique yielded good fusion rate without complications and can be considered as a good

    BACKGROUND:In recent years, many scholars adopted a joint non-fusion and fusion spinal fixation for multisegmental cervical spondylotic myelopathy, and achieved good clinical results. However, long-term clinical efficacy and possible related complications also require long-term fol ow-up of more in-depth study. OBJECTIVE:To review the research and application progress of anterior fusion and non-fusion fixation surgical operation for cervical myelopathy. METHODS:Computer-based search was conducted in China Journal Ful-text Database and PubMed database by the first author for articles related to anterior fusion and non-fusion fixation surgical operation for cervical myelopathy published between January 2004 and January 2014. The key words were“implant material;cervical spondylotic myelopathy;anterior;surgery;fusion;non-fusion;progress;hybrid;summary”in Chinese and“implant material;cervical spondylotic myelopathy;anterior;surgery/operation;fusion;non-fusion;research progress;hybrid;summary”in English. Final y, 35 articles were included for review. RESULTS AND CONCLUSION:Fusion and non-fusion fixation methods for cervical spondylotic myelopathy had their own advantages. From the view point of indications, the non-fusion fixation was relatively limited. Currently, the fusion fixation was stil the main method in treatment of cervical myelopathy. Non-fusion method as an emerging fixation method also achieved good short-period results, but it needs a long fol ow-up study. Hybrid fixation integrates the advantages of both methods, and can reduce the pressure. Simultaneously, Hybrid fixation also can reduce fusion segments, and retain the range-of-motion of the cervical spine as much as possible. Hybrid fixation becomes a hot topic in recent studies. However, most current researches on Hybrid fixation are retrospective study, lack of control. The overal fol ow-up time is short. Thus, Hybrid fixation needs to be researched more deeply.%背景:近年来,许多国

    Results obtained in 43 Rheumatoid arthritis (RA) patients with cervical myelopathy are described; all patients showed several alarm signs together with neurological disturbances. Thirty-four cases were operable; nine patients were not operated upon for various reasons (refusal, and general condition). In the surgically treated patients, the changes were localized in the C1-C2 area (n = 20), in the area below C2 (n = 5), or in both (n = 9). The patients were put on skull traction pre- and post-operatively and nursed on a circo-electric bed. Pre-operatively, the duration of traction varied from a few days to weeks (mean 3 weeks). Post-operatively, the patients were given continuous skull traction for 2 1/2-3 months. This procedure yielded neurological improvement and a stable graft in all but two patients. On follow-up, recurrence of neurological complaints was seen in nine patients, in four due to a new slip at a lower level. Three of these cases were reoperated with good results. Twenty-three patients have died: four 'early' (one pre-operatively and three within 6 weeks post-operatively) and 19 'late'. The mean duration of follow-up was 4.5 years. In those who died 'late', the cause of death was due to the effects of an unstable graft in two cases and in the others the causes were not related to changes in the cervical spine. In the 10 patients who are still alive the mean duration of follow-up is 5 years. The nine patients who were not operated upon all died within a year, 4 of them due to consequences of cord compression. If cervical spondylodesis is feasible in an RA patient with myelopathy, the procedure is advocated. PMID:6529877

    Full Text Available Aim: The association of single or multiple level cervical spondylotic disease with atlantoaxial instability is assessed. The implications of identifying and treating atlantoaxial instability in such an association are highlighted. Materials and Methods: The analysis is based on an experience with 11 patients treated during the period June 2013-June 2014. All patients had single or multilevel cervical spondylotic disease. The spinal canal compromise and evidence of cord compression was evident on imaging in the cervical subaxial spine and was related to disc bulges and osteophytic bars. There was no or relatively insignificant compression of the cervicomedullary cord by the odontoid process. There was no evidence of odontoid process-related instability on dynamic imaging. Apart from presence of features of cervical spondylosis, investigations and surgical exploration and direct manual handling of the facets revealed evidence of Type B (posterior atlantoaxial′facetal′ instability in all patients. Our 5-point clinical grading system and Japanese Orthopaedic Association (JOA scores were used to monitor the patients both before and after surgery and at follow-up. Surgery involved both at lantoaxial and subaxial cervical fixation. During the average period of follow-up of 9 months (5-17 months, all patients showed remarkable and gratifying neurological recovery. Conclusion: We conclude that atlantoaxial facetal instability can be ′frequently′ associated with cervical spondylosis and needs surgical stabilization. Our surgical outcome analysis suggests that missing or ignoring the presence of atlantoaxial facetal instability can be an important cause of suboptimal result or failure of surgery for cervical spondylotic myelopathy.

    Full Text Available Background: Cervical disc replacement is becoming an increasingly popular treatment option for cervical myelopathy. It retains motion at the affected segment, unlike anterior cervical discectomy and fusion. The aim of this study is to assess the outcomes of a series of patients who underwent Activ C disc replacement for cervical myelopathy. Materials and Methods: A series of patients at the above Trust with clinical and radiological evidence of cervical myelopathy who were suitable for cervical disc replacement from 2007 to 2009 were included. Implants were inserted by one of two consultant surgeons {IMS, MO′M}. Patients were assessed preoperatively and at six, 12 and 24 months, postoperatively, with a visual analogue score (VAS for neck and arm pain severity and frequency, the Neck Disability Index questionnaire (NDI and the Centre for Epidemiologic Studies Depression questionnaire (CES-D. Results: Ten patients underwent surgery between May 2007 and July 2009, 6 women, and 4 men. Average age was 54 years (40-64. Disc levels replaced were: four at C4-5; eight at C5-6; seven at C6-7. Three patients had one disc replaced, five patients had two discs replaced, and two patients had three discs replaced. The VAS for neck pain improved from 5.9 pre-operatively to 1.4-24 months postoperatively and the VAS arm pain improved from 5.4 to 2.6. The NDI improved from 51% preoperatively to 26.8% at 24 months postoperatively. The CES-D showed a slight increase from 19.5 preoperatively to 21.7 at 24 months, postoperatively. Conclusion: Cervical decompression and disc replacement improves pain and function in patients with cervical myelopathy. This benefit is maintained at 24 months post op, with no cases requiring revision.

    Langerhans cell histiocytosis (LCH), a disorder of the phagocytic system, is a rare condition. Moreover, spinal involvement causing myelopathy is even rare and unusual. Here, we report a case of atypical LCH causing myelopathy, which was subsequently treated by corporectomy and fusion. An 8-year-old boy presented with 3 weeks of severe neck pain and limited neck movement accompanying upper and lower limbs motor weakness. CT scans revealed destruction of C5 body and magnetic resonance imaging showed a tumoral process at C5 with cord compression. Interbody fusion using anterior cervical plate packed by autologus iliac bone was performed. Pathological examination confirmed the diagnosis of LCH. After the surgery, the boy recovered from radiating pain and motor weakness of limbs. Despite the rarity of the LCH in the cervical spine, it is necessary to maintain our awareness of this condition. When neurologic deficits are present, operative treatment should be considered. PMID:22552159

    2012-02-01

    The surgical treatment of cervical spondylosis and resulting cervical radiculopathy or myelopathy has evolved over the past century. Surgical options for dorsal decompression of the cervical spine includes the traditional laminectomy and laminoplasty, first described in Asia in the 1970\\'s. More recently the dorsal approch has been explored in terms of minimally invasive options including foraminotomies for nerve root descompression. Ventral decompression and fusion techniques are also described in the article, including traditional anterior cervical discectomy and fusion, strut grafting and cervical disc arthroplasty. Overall, the outcome from surgery is determined by choosing the correct surgery for the correct patient and pathology and this is what we hope to explain in this brief review.

    Full Text Available High cervical ossified ligamentum flavum (OLF is rare and may cause progressive quadriparesis and respiratory failure . Our two patients had unilateral OLF between C1 and C4 levels. MR showed a unilateral, triangular bony excrescence with low signal and a central, intermediate or high signal on all pulse sequences due to bone marrow within. There was Type I thecal compression (partial deficit of contrast media ring. The first patient had a linear and nodular OLF with calcification within tectorial membrane, C2-3 fusion and unilateral C2-facetal hypertrophy; and the second patient, a lateral, linear OLF with loss of lordosis and C3-6 spondylotic changes. A decompressive laminectomy using "posterior floating and enbloc resection" brought significant relief in myelopathy. Histopathology showed mature bony trabeculae, bone marrow and ligament tissue. The coexisting mobile cervical vertebral segment above and congenitally fused or spondylotic rigid segment below the level of LF may have led to abnormal strain patterns within resulting in its unilateral ossification. In dealing with cervical OLF, carefully preserving facets during laminectomy or laminoplasty helps in maintaining normal cervical spinal curvature.

    Cervical spinal cord dysfunction can result from either traumatic or nontraumatic causes, including tumors, infections, and degenerative changes. In this article, we review the range of degenerative spinal disorders resulting in progressive cervical spinal cord compression and propose the adoption of a new term, degenerative cervical myelopathy (DCM). DCM comprises both osteoarthritic changes to the spine, including spondylosis, disk herniation, and facet arthropathy (collectively referred to as cervical spondylotic myelopathy), and ligamentous aberrations such as ossification of the posterior longitudinal ligament and hypertrophy of the ligamentum flavum. This review summarizes current knowledge of the pathophysiology of DCM and describes the cascade of events that occur after compression of the spinal cord, including ischemia, destruction of the blood-spinal cord barrier, demyelination, and neuronal apoptosis. Important features of the diagnosis of DCM are discussed in detail, and relevant clinical and imaging findings are highlighted. Furthermore, this review outlines valuable assessment tools for evaluating functional status and quality of life in these patients and summarizes the advantages and disadvantages of each. Other topics of this review include epidemiology, the prevalence of degenerative changes in the asymptomatic population, the natural history and rates of progression, risk factors of diagnosis (clinical, imaging and genetic), and management strategies.

    Full Text Available Background: Cervical spondylotic amyotrophy (CSA is a rare clinical syndrome resulting from cervical spondylosis. Surgical treatment includes anterior cervical decompression and fusion (ACDF, and laminoplasty with or without foraminotomy. Some studies indicate that ACDF is an effective method for treating CSA because anterior decompression with or without medial foraminotomy can completely eliminate anterior and/or anterolateral lesions. We retrospectively evaluated outcome of surgical outcome by anterior cervical decompression and fusion (ACDF. Materials and Methods: 28 CSA patients, among whom 12 had proximal type CSA and 16 had distal type CSA, treated by ACDF, were evaluated clinicoradiologically. The improvement in atrophic muscle power was assessed by manual muscle testing (MMT and the recovery rate of the patients was determined on the basis of the Japanese Orthopedic Association (JOA scores. Patient satisfaction was also examined. Results: The percentage of patients, who gained 1 or more grades of muscle power improvement, as determined by MMT, was 91.7% for those with proximal type CSA and 37.5% for those with distal type CSA (P < 0.01. The JOA score-based recovery rates of patients with proximal type and distal type CSA were 60.8% and 41.8%, respectively (P < 0.05. Patient satisfaction was 8.2 for those with proximal type CSA and 6.9 for those with distal type CSA (P < 0.01. A correlation was observed among the levels of improvement in muscle power, JOA score based recovery rate, patient satisfaction and course of disease (P < 0.05. Conclusion: ACDF can effectively improve the clinical function of patients with CSA and result in good patient satisfaction despite the surgical outcomes for distal type CSA being inferior to those for proximal type CSA. Course of disease is the fundamental factor that affects the surgical outcomes for CSA. We recommend that patients with CSA undergo surgical intervention as early as possible.

    OBJECTIVE Cervical spondylotic myelopathy (CSM) is the most common cause of spinal cord dysfunction in adults. In spite of this, the impact of the changes in myelopathic signs following cervical decompression surgery and their relationship to functional outcome measures remains unclear. The main goals of our study were to prospectively assess changes in myelopathic signs with a functional outcome scale (the modified Japanese Orthopaedic Association [mJOA] scale) following cervical decompression surgery and to objectively test a proposed new myelopathy scale (MS). METHODS Between 2008 and 2011, 36 patients with CSM were observed following cervical decompression surgery. Patient data including mJOA and MS scores were prospectively collected and analyzed preoperatively and at 1 year after surgery. RESULTS In this cohort, reflex, Babinski, and proprioception signs showed statistically significant improvement following surgery at 1 year (p = < 0.001, p = 0.008, and p = 0.015, respectively). A lesser degree of improvement was observed with the Hoffman sign (p = 0.091). No statistically significant improvement in clonus occurred (p = 0.368). There was a significant improvement in mJOA (p ≤ 0.001) and MS (p ≤ 0.001) scores at 1 year compared with the preoperative scores. The results showed an inverse correlation between MS and mJOA scores both pre- and postoperatively (Spearman's correlation coefficient = -0.202 preoperatively and -0.361 postoperatively). CONCLUSIONS Improvement in myelopathic signs was noted following cervical decompression surgery in patients with CSM. The newly devised MS scale demonstrated these findings, and the new MS scale correlates with improvement in mJOA scores in this patient cohort. PMID:26849710

    Myelopathy is an inclusive term, referring to pathology leading to a neurologic deficit related to the spinal cord. The clinical diagnosis of myelopathy requires a detailed history and physical examination to define the clinical syndrome. Neuroimaging is indicated in most instances of new-onset myelopathy. It is indicated also when the worsening of a myelopathy is unexplained. Advances in neuroimaging have proved to play a vital role in diagnosis. Appropriate diagnosis and treatment are dependent upon an adequate imaging evaluation to establish the presence of mechanical stability, extrinsic spinal cord compression, or an intramedullary lesion. The most frequent etiology of myelopathy is related to degenerative disease of the spine from osteophyte or extruded disc material causing compression of the spinal cord in the cervical or thoracic spine. The next common etiologies are spinal cord compression due to extradural masses caused by metastatic disease to bone or blunt trauma. In these cases, emergency imaging should be performed to assess the nature of the lesion causing the myelopathy and plan the most appropriate treatment. Also urgent imaging should be performed when an abscess in the spinal canal is suspected. Less urgent is imaging of primary neoplasms of the meninges, roots, or spinal cord, as well as noninfectious inflammatory processes, such as multiple sclerosis, and neurodegenerative, vascular, nutritional, or idiopathic disorders leading to myelopathy. Although a survey of the entire spinal cord can be performed with imaging, it is more appropriate to define from the clinical findings what levels of the spine and spinal cord should be imaged. This approach helps limit the likelihood of false-positive imaging findings that may encourage needless attempts to fix what is not broken. Similarly, the most appropriate imaging study and protocol should be selected in order to provide a timely and accurate diagnosis. To do so requires detailed knowledge

    In the case of cervical spine myelopathy, alteration of glucose metabolism rate, image findings and clinical manifestation were compared with those of healthy volunteer by high resolution 18FDG-PET. Authors investigated in 21 healthy volunteers, and 22 patients with cervical spine myelopathy. Patients had cervical spondylosis myelopathy (12 cases), cervical spine herniated disk (8 cases), posterior longitudinal ligament osteosis (2 cases). MRI image was observed after and before surgery, medulla spinalis configuration and brightness alteration after decomposition were checked. Standardized uptake value (SUV) of glucose by cervical spinal cord in radiculopathy group (n=4) was similar to that in normal group but that in myelopathy group (n=14) was decreased significantly (p18FDG represents degree of a critical condition of cervical myelopathy, and consequence assessment of cervical myelopathy is possible by SUV.

    The usefulness of cine-MRI using motion pictures was studied on 75 patients with postoperative cervical myelopathy, and morphology of cervical spine and cervical cord, postoperative MRI, and postoperative outcome were investigated. T1-weighted images by SE method and T2-weighted images by gradient field echo were obtained. Cine-MR images were classified into 5 according to the site of cerebrospinal fluid flow void and its degree (anterior type, 21; anteroposterior type, 30; posterior type, 7; incomplete block type, 15; complete block type, 2), and relationship between clinical features were studied. This method enabled dynamic noninvasive evaluation of spinal cord compression by cerebrospinal fluid flow. (S.Y.).

    Intracranial dural arteriovenous fistula (dAVF) usually results in various problems in the brain. But it can be presented as a myelopathy, which may make early diagnosis and management to be difficult. We recently experienced a case of cervical myelopathy caused by intracranial dAVF. A 60-year-old man presented with a 3-year history of gait disturbance due to a progressive weakness of both legs. Neurological examination revealed spastic paraparesis (grade IV) and Babinski sign on both sides. Magnetic resonance imaging showed serpentine vascular signal voids at C2-T1 on T2-weighted image with increased signal intensity and swelling of spinal cord at C1-C4. We performed a brain computed tomography angiography and found intracranial dAVF with multiple arteriovenous shunts. Venous drainages were noted at tentorial veins and cervical perimedullary veins. After Onyx embolization, the patient showed gradual improvement in motor power and gait disturbance. The venous drainage pattern is a well-known prognostic factor of dAVF. In our case, the intracranial dAVF drained to spinal perimedullary vein, which seemed to result in the ischemic myelopathy. Although it is rare condition, it sometimes can cause serious complications. Therefore, we should keep in mind the possibility of intracranial dAVF when a patient presents myelopathy. PMID:27437016

    Langerhans cell histiocytosis (LCH), a disorder of the phagocytic system, is a rare condition. Moreover, spinal involvement causing myelopathy is even rare and unusual. Here, we report a case of atypical LCH causing myelopathy, which was subsequently treated by corpectemy and fusion. A 5-year-old boy presented with 3 weeks of severe neck pain and limited neck movement accompanying right arm motor weakness. CT scans revealed destruction of C7 body and magnetic resonance imaging showed a tumoral process at C7 with cord compression. Interbody fusion using cervical mesh packed by autologus iliac bone was performed. Pathological examination confirmed the diagnosis of LCH. After the surgery, the boy recovered from radiating pain and motor weakness of right arm. Despite the rarity of the LCH in the cervical spine, it is necessary to maintain our awareness of this condition. When neurologic deficits are present, operative treatment should be considered.

    Full Text Available Abstract Background In primary care, it is often difficult to diagnose cervical myelopathy. However, a delay in treatment could cause irreversible aftereffects. With a brief and effective self-administered questionnaire for cervical myelopathy, cervical myelopathy may be screened more easily and oversight may be avoided. As there is presently no screening tool for cervical myelopathy, the aim of this study was to develop a self-administered questionnaire for the screening of cervical myelopathy. Methods A case-control study was performed with the following two groups at our university hospital from February 2006 to September 2008. Sixty-two patients (48 men, 14 women with cervical myelopathy who underwent operative treatment were included in the myelopathy group. In the control group, 49 patients (20 men, 29 women with symptoms that could be distinguished from those of cervical myelopathy, such as numbness, pain in the upper extremities, and manual clumsiness, were included. The underlying conditions were diagnosed as carpal tunnel syndrome, cubital tunnel syndrome, thoracic outlet syndrome, tarsal tunnel syndrome, diabetes mellitus neuropathy, cervical radiculopathy, and neuralgic amyotrophy. Twenty items for a questionnaire in this study were chosen from the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire, which is a new self-administered questionnaire, as an outcome measure for patients with cervical myelopathy. Data were analyzed by univariate analysis using the chi-square test and by multiple logistic regression analysis. According to the resulting odds ratio, β-coefficients, and p value, items were chosen and assigned a score. Results Eight items were chosen by univariate and multiple logistic regression analyses and assigned a score. The Hosmer-Lemeshow statistic showed p = 0.805. The area under the receiver operation characteristic curve was 0.86. The developed questionnaire had a sensitivity of 93.5% and a

No hubo diferencias significativas entre el Índice de Torg calculado por la radiografía y el de la resonancia magnética, siendo menores los índices observados en la RM (radiografía: 0,73 ± 0,17 vs RM: 0,48 ± 0,14, p OBJECTIVE: Cervical spondylotic myelopathy (SCM is a dysfunction related to spinal cord degeneration typical of aging. In the imaging studies can achieve a measure of the Torg index to estimate cervical stenosis. We aim therefore to measure the Torg index in X-rays and Magnetic Resonance (MR, to investigate possible discrepancies between the methods of measurement. METHODS: The Torg Index was measured on radiographs and MR of the cervical spine, obtained by determining the relationship between the posterior surface of the vertebral body and the nearest point to the corresponding laminar line, divided by the sagittal diameter of vertebral body. RESULTS: A total 29 patients has participated, 10 women and 19 men, with mean age of 48.1 ± 11 years, weight 68.7 ± 5kg and height 1.68 ± 0.6m. There were significant differences between the Torg Index calculated by radiography and MR, and lower rates observed on MR (radiography: 0.73 ± 0.17 vs. RM: 0.48 ± 0.14, p <0.05. However, both measurements reflect the same result: absolute cervical stenosis (Torg index < 0.8. CONCLUSIONS: Our results confirm reports by other authors who believe that the Torg Index measured by radiography, as recommended, minimizes the actual cervical canal stenosis. Our study suggests that MRI allows better estimate of the degree of stenosis, although our results regarding the degree of cervical stenosis were statistically similar.

    Magnetic resonance imaging (MRI) was performed in 18 cases of cervical myelopathy. They were ''disc herniation'' 8 cases, ''canal stenosis'' 5 cases, and ''ossification of posterior longitudinal ligament (OPLL)'' 5 cases. The midsagittal section was obtained in each cases. The pulse sequence was Spin Echo (SE) technique with both T/sub 1/-weighted SE (Tr = 400, Te = 40) and T/sub 2/-weighted SE (Tr = 2000, Te = 80). Cervical-cord compression by herniated disc, yellow ligament, OPLL, or osteophyte was shown very clealy on the T/sub 1/-weighted image. Cord compression was increased by cervical extension and decreased by flexion. MRI was very useful in detecting the involved levels and in selecting the operative procedures. T/sub 2/-weighted image was taken in 9 cases. High signal intensity area was noted at the cord which was compressed in 7 cases. The true mechanism of this phenomenon is unknown yet, but this might be a clue to solve the pathogenesis of myelopathy. MRI was performed in 9 cases in order to evaluate post-operative cord decompression. Cord decompression was confirmed in 8 cases except for one case. MRI was also useful for postoperative evaluation.

  14. Computed tomography in the evaluation of caudal cervical spondylomyelopathy of the Doberman Pinscher

    International Nuclear Information System (INIS)

    Caudal cervical spondylomyelopathy is a common neurologic disorder of Doberman pinschers which has a number of striking similarities to cervical spondylotic myelopathy in humans. Diagnosis of this human disease is facilitated considerably by the use of computed tomographic (CT) myelography. Sixteen Doberman pinscher dogs with caudal cervical spondylomyelopathy were studied by conventional myelography followed by CT myelography. A close correlation was noted between the CT myelographic appearance of the cervical spinal cord in these dogs, and that reported for human cervical spondylotic myelopathy. Five dogs had atrophy of the spinal cord, and in another there was an accumulation of contrast medium within the spinal cord. These features are often associated with a poor response to surgical decompression in humans with cervical spondylotic myelopathy. The CT examination provided information that could not be obtained by conventional myelography alone and should be considered as an additional diagnostic procedure in dogs with caudal cervical spondylomyelopathy

  16. Surgical results and MRI findings of cervical myelopathy treated with anterior decompression and fusion

    International Nuclear Information System (INIS)

    We reviewed 19 patients with cervical myelopathy treated with anterior decompression and fusion. Etiology of cervical myelopathy was cervical disc herniation (CDH) in 13 patients and cervical spondylosis (CSM) in 6. Clinical recovery rate (%) was calculated from preoperative cervical myelopathy score (JOA) and the score at follow-up. Correlation between the clinical recovery rate and MRI findings (area and flatness at the narrowest part of the spinal cord), age at surgery, duration of myelopathy and pre-operative clinical score were analyzed separately in the CDH and CSM groups. Clinical recovery rate averaged 69% in the CDH group and 75% in the CSM group. In the CDH group, average clinical recovery rate in patients younger than 60 years was 80 and in patients over 60 years was 60. There was a significant negative correlation between the clinical recovery rate and age at surgery (p<0.05). No significant correlation was found between the clinical recovery rate and other factors investigated. (author)

    Full Text Available Background: In multilevel spinal cord compression caused by cervical spondylosis, surgeonsface the choice of performing a posterior route as a laminectomy orlaminoplasty, or an anterior route as multiple adjacent interbody decompressionsor corpectomies. The anterior cervical operation is not considered bysome clinicians because of concerns about complications and the complexityof multilevel anterior cervical surgery.Methods: In this retrospective study, 14 patients with multilevel cervical spondylosiswho were operated on via an anterior route were enrolled to evaluate thecomplexity, safety, and clinical results. The collected parameters were operationtime, blood loss, hospital days, and early and late complications forevaluating the operative complexity, radiographic follow-up for evaluatingfusion, graft problems, implants problems, and the recovery rate using theJapanese Orthopaedic Association score (JOA score for evaluating the operativeresults.Results: The mean operation time was 363.4 min, and blood loss was 431.4 ml. Anearly complication was noted in 1 patient with combined deep vein thrombosisand a pulmonary embolism. Late complications were screw breakage in1 patient and screw loosening in 5 patients. The mean duration of follow-upwas 21.9 months. The mean recovery rate of the JOA score was 38.8% postoperativelyand 51.9% at the final follow-up. The fusion rate was 100% inthis series.Conclusions: Anterior cervical decompression and fusion for multilevel stenosis requires alonger operation time than posterior procedures; however, the clinical resultsare satisfactory.

    OBJECT Posterior cervical surgery, expansive laminoplasty (EL) or laminectomy followed by fusion (LF), is usually performed in patients with multilevel (≥ 3) cervical spondylotic myelopathy (CSM). However, the superiority of either of these techniques is still open to debate. The aim of this study was to compare clinical outcomes and postoperative kyphosis in patients undergoing EL versus LF by performing a meta-analysis. METHODS Included in the meta-analysis were all studies of EL versus LF in adults with multilevel CSM in MEDLINE (PubMed), EMBASE, and the Cochrane library. A random-effects model was applied to pool data using the mean difference (MD) for continuous outcomes, such as the Japanese Orthopaedic Association (JOA) grade, the cervical curvature index (CCI), and the visual analog scale (VAS) score for neck pain. RESULTS Seven studies comprising 302 and 290 patients treated with EL and LF, respectively, were included in the final analyses. Both treatment groups showed slight cervical lordosis and moderate neck pain in the baseline state. Both groups were similarly improved in JOA grade (MD 0.09, 95% CI -0.37 to 0.54, p = 0.07) and neck pain VAS score (MD -0.33, 95% CI -1.50 to 0.84, p = 0.58). Both groups evenly lost cervical lordosis. In the LF group lordosis seemed to be preserved in long-term follow-up studies, although the difference between the 2 treatment groups was not statistically significant. CONCLUSIONS Both EL and LF lead to clinical improvement and loss of lordosis evenly. There is no evidence to support EL over LF in the treatment of multilevel CSM. Any superiority between EL and LF remains in question, although the LF group shows favorable long-term results. PMID:25815808

    Full Text Available Background: This is a commentary on the article laminoplasty versus laminectomy and fusion (LF for multilevel cervical myelopathy: A meta-analysis of clinical and radiological outcomes by Chang-Hyun Lee et al. Here, the authors utilized seven studies to compare the efficacy of cervical expansive laminoplasty (EL versus laminectomy and fusion (LF to address three or more level multilevel cervical spondylotic myelopathy (CSM. Both procedures led to similar degrees of neurological recovery and short-term loss of lordosis, but found that LF led to more favorable long-term results. Methods: For patients with three or more level CSM, laminectomy followed by an instrumented fusion (LF has major advantages; open bilateral decompression of the nerve roots, while minimizing the risk of inadvertent injury to the cord, and the fusion′s maintenance of lordosis. Results: Some would argue that inadvertent cord/root injury is greater utilizing any of the EL techniques; e.g., unilateral, bilateral, or spinous process splitting techniques. In short, why risk cord/root injury by manipulating the compressive posterior/posterolateral elements, which are already threatening neural function. Conclusion: Although the results of EL versus LF appeared comparable in the short-term in these seven articles, LF resulted in better long-term outcomes. Some would also argue that LF, utilizing an open approach offers safer bilateral neural exposure and decompression.

  2. Two cases of cervical spondylotic amyotrophy, as examined by somatosensory evoked potentials and metrizamide CT

    International Nuclear Information System (INIS)

    Two cases of cervical spondylotic amyotrophy were reported. Case 1 (a 74-year-old man) and Case 2 (a 73-year-old man) showed severe weakness with marked muscle atrophy in the shoulder girdles and biceps, but negative pyramidal tract sign. Minimal superficial sensory disturbance at the 5th and 6th cervical segments was observed in Case 2. In the two cases, metrizamide CT revelaed the narrowing of the spinal canal and the marked flattening of the cord at C3 - C6. The somatosensory evoked potentials (SEPs) to the median nerve stimulation showed the marked delay between P 13 - P 11 latency in the two cases. The SEPs to the posterior tibial nerve stimulation showed an abnormal P 2 - N 20 interpeak latency in Case 1. Findings of metrizamide CT and SEPs suggested that the main cause of the amyotrophy of our cases was the spinal cord lesion around the anterior horn. (author)

    Full Text Available OBJECTIVE : To study the neurological recovery pattern and clinical recovery after surgical intervention in patients of degenerative cervical myelopathy and radiculopathy to know the surgical outcome, at L okmanya T ilak M unicipal M edical C ollege , Mumbai, Maharashtra . METHOD : We ca rried out prospective and retrospective observational study of 30 patients with functional disability secondary to cervical degenerative myelopathy and radiculopathy who underwent surgery for decompression of the cervical spinal cord with or without spinal stabilization. March 2012 to March 2013 were studied and followed for more than 1year. All patients were operated by a single surgeon and reviewed independently. All the patients had received appropriate conservative management before undergoing surgical intervention . Data was analysed by using appropriate software. RESULTS : The study group comprised of 27 males and 3 females aged between 36 and 75 years with a mean age of 56 years that presented with functional disability secondary to cervical myelopathy and radiculopathy. Pain and neurological examination were used as criteria at sequential follow – ups. Functional outcome was assessed using Japanese Orthopaedic Association score, Oswestry Disability Index and Visual Analogue Scale. It was found that neuro logical recovery for myelopathy by mJOA score at intervals between 15 days to 3 months was significant after which recovery was occurring but was not significant. Anterior cervical discectomy with fusion for 1 - 2 levels has given good results than posterior laminectomy for 3 or more levels. Cervical radiculopathy alone has good recovery results after decompression surgery than myelopathy or myelopathy with radiculopathy. CONCLUSION: Based on this study, we found that the results of surgery for cervical spon dylotic myelopathy and radiculopathy are excellent. The best neurological and functional recovery is seen in patients with mild to moderate

    BACKGROUND: Compression occurs in several horizontal spinal cords of patients with multilevel cervical spondylotic myelopathy (CSM), especially compression is attacked on both ends of spinal cord. Therefore, there are so many choices of approach and way for operation. However, which approach and way have good effects and few complications is still controversial up to now.OBJECTIVE: To observe the therapeutic effect of anterior multilevel decompression and internal fixation on multilevel CSM and compare with posterior mono-open-door vertebral canal expanding laminoplasty.DESIGN: Contrast analysis.SETTING: Department of Orthopaedics, Xiangya Hospital of South China University; Department of Orthopaedics, People's Hospital of Liuzhou.PARTICIPANTS: A total of 68 patients with multilevel CSM were selected from the Department of Orthopaedics, Xiangya Hospital of South China University from January 2000 to June 2005. All patients were divided into anterior approach surgery group (n =33) and posterior approach surgery group (n =35). Baseline data between the two groups were comparable.METHODS:①Anterior approach surgery group: All 33 patients received bone-transplanting and internal fixation through cervical spine. Among them, auto-iliac bone-graft was transplanted into 17 cases, Cage auto-bone graft combining with allogenic bone was transplanted into 11 cases, and titan-net and auto-bone combining with allogenic bone was transplanted into 5 cases. In addition, long segments were dealt with internal fixation of anterior cervical spine locking plate (CSLP). Among them, 12 cases used Orion plate, 13 cased used Zephir palte, and 8 cases used Codman plate. ②Posterior approach surgery group: Fifteen patients received total laminectomy for decompression and other twenty patients received mono-open-door vertebral canal expanding laminoplasty. After laminoplasty, all patients received negative pressure and neck support fixation for three months.MAIN OUTCOME MEASURES:

    Full Text Available Cervical myelopathy (CM is mostly a degenerative process ending in myelopathic and/or radiculopathic syndromes. On T2-weighted magnetic resonance imaging (MRI, CM appears as a hyperintense area near the spondylotic spine. This high intensity signal depends on the impact of outer forces and their duration. It also determines the prognosis of the surgical candidate. A 40-year-old male patient admitted to our clinic with right upper extremity weakness and hypoesthesia that had started 2 months earlier. On neurological examination there was 2/5 motor weakness of right biceps brachii, and hypoesthesia over right C6 dermatome. Right upper extremity deep tendon reflexes were hypoactive, but lower ones were hyperactive. After clinical and radiological work-up, preliminary diagnosis was directed to a spinal intramedullary tumor. Total resection of the herniated cervical disc fragment and the mass lesion was managed. Pathology of the mass lesion was compatible with subacute infarct tissue and inflammatory response. Final diagnosis was CM under effect of cervical disc herniation. Contrast-enhanced spinal cord myelopathic lesions are very rare and resemble much more tumors and inflammatory processes. However, the principal treatment approach totally differs depending on pathology. When there are both a disc herniation and a high clinical suspicion; biopsy should be delayed. The most probable solution will be surgery for the disc disease with thorough preoperative scanning of vascular malformations; clinical and radiological close follow-up after surgery. Biopsy or surgical resection can be performed if patient deteriorates despite the primary surgery.

  12. Double-door laminoplasty using autologous spinous process for the management of cervical myelopathy

    International Nuclear Information System (INIS)

    We describe a technique of double-door laminoplasty for the management of cervical myelopathy using the autologous spinous process instead of an artificial spacer. The aims in the present study were to determine the fusion rate and the incidence rate of breakage in the autologous spinous process, and to assess its efficacy for cervical laminoplasty. Twenty-three patients of cervical myelopathy were treated with double-door laminoplasty followed by implantation of the autologous spinous process. The spinous process from C3 to C7 was resected, at 8 mm from the basal part of the spinous process. The autologous spinous process was made from the removed spinous process, and was implanted between each expanded laminae. Post-operative CT scanning determined the fusion rate between the expanded laminae and the autologous spinous process as 70.4% at 3 months, and 93.5% at 6 months, after the operation. There was no dissociation and no breakage in the autologous spinous process during the follow-up observation period. There were certain advantages to our technique including the high fusion rate and good stability in the autologous spinous process. In addition, this technique was less expensive than other techniques using an artificial spacer. These findings indicated that this technique was a reliable procedure for effectively treating of cervical myelopathy which are caused by multisegmental cervical canal stenosis. (author)

    Background A considerable number of patients with cervical spondylosis complain about one or multiple atypical symptoms such as vertigo, palpitations, headache, blurred vision, hypomnesia, and/or nausea. It remains unclear whether surgical intervention for cervical spondylosis can also effectively alleviate those symptoms. The current study was performed to see if anterior cervical diskectomy and fusion (ACDF) offers such an extra benefit for patients with cervical spondylosis. Objective To investigate if patients who received ACDF for the treatment of cervical spondylotic myelopathy and/or radiculopathy can also achieve alleviation of certain atypical symptoms associated with cervical spondylosis after the surgery in the long run. Methods Sixty-seven patients who underwent ACDF for the treatment of cervical spondylotic myelopathy and/or radiculopathy were involved in this study. All these patients also complained about various associated atypical symptoms. They were followed up for 26 to 145 months after the surgery. Severity and frequency scores of the atypical symptoms before the surgery and at last follow-up were compared by paired t tests. Results Most patients reported significantly alleviated symptoms at the last follow-up compared with before the surgery. The severity of vertigo, headache, nausea, and palpitations were significantly alleviated at the last follow-up (with p values of p cervical spondylotic myelopathy and/or radiculopathy, but it is not effective in alleviating symptoms such as tinnitus, blurred vision, and hypomnesia. It can be considered for alleviating atypical symptoms when other treatment options prove ineffective. PMID:27168319

    Hirayama's disease is a benign juvenile form of focal amyotrophy affecting the upper limbs. Previous studies have suggested that the disorder is a neck flexion induced cervical myelopathy. We report clinical and magnetic resonance imaging findings in nine patients with Hirayama's disease. Cervical imaging of seven patients revealed spinal cord changes consisting of focal atrophy and foci of signal alterations. On neck flexion a forward movement and mild reduction in the anteroposterior diameter of the lower cervical cord against the vertebral bodies was noted in affected individuals as well as in five normal controls. In contrast to earlier reports, none of our patients showed complete obliteration of the posterior subarachnoid space. Measurement of the anteroposterior spinal cord diameter in each vertebral segment (C4-C7) revealed no significant differences in the degree of spinal cord flattening between the two groups. Furthermore, two of our patients had significant degenerative changes in the cervical spine (disc herniation, retrospondylosis) contralateral to the clinically affected side. These degenerative changes resulted in a marked cord compression on neck flexion but were not associated with ipsilateral clinical abnormalities or spinal cord alterations. Our results argue against a flexion-induced cervical myelopathy and support the view that Hirayama's disease is an intrinsic motor neuron disease. PMID:10631640

  15. Laminoplasty Techniques for the Treatment of Multilevel Cervical Stenosis

    Full Text Available Laminoplasty is one surgical option for cervical spondylotic myelopathy. It was developed to avoid the significant risk of complications associated with alternative surgical options such as anterior decompression and fusion and laminectomy with or without posterior fusion. Various laminoplasty techniques have been described. All of these variations are designed to reposition the laminae and expand the spinal canal while retaining the dorsal elements to protect the dura from scar formation and to preserve postoperative cervical stability and alignment. With the right surgical indications, reliable results can be expected with laminoplasty in treating patients with multilevel cervical myelopathy.

    The objective of this study is to discuss the possible role of cervical posterior epidural plexus engorgement during cervical flexion in the pathogenesis of Hirayama myelopathy. In Hirayama disease, MRI during neck flexion often shows that the posterior dura detaches from the posterior arches compressing the spinal cord. Autopsies demonstrated asymmetric changes in the anterior horns consistent with chronic ischemic damage, attributed to arterial insufficiency during flexion or to microcirculatory changes due to compression by the tight dura. In a 15-year-old patient with 5-year history of distal upper limbs weakness, MRI demonstrated marked venous engorgement of the posterior epidural plexus in cervical flexion, confirmed by angiography. Laminectomy from C3 to C6 with duraplasty was performed. At one-year follow-up, the clinical condition of the patient remained stable. In Hirayama myelopathy, compression of the spinal cord by the tight dura is probably the most important pathogenetic factor. However, venous congestion in flexion might play an additional role in determining spinal cord ischemic changes. PMID:20857161

  17. MR venography in cervical myelopathy before and after direct skull traction

    International Nuclear Information System (INIS)

    MR venography (MRV) was performed to evaluate the anterior cervical venous plexuses in five normal volunteers and eight patients with cervical myelopathy before and after direct skull traction. Visibility of the plexuses from C2 to C7 was evaluated and scored by five observers in those groups. The venography was performed with FISP sequences (fast imaging with steady state precession) and with the injection of Gd-derivatives. The MRV was obtained after maximum-intensity projection and 3D reconstruction. In the normal volunteers, the internal vertebral plexus (IVP), intervertebral vein (IV) and anastomotic vein (AV) were all well demonstrated. In the patients, those plexuses were less well demonstrated in comparison with the normal volunteer, particularly in C5 which is the most frequently affected area. The patient group had lower scores than the normal group. However, the score at C5 was not lower than those at non-affected sites. After treatment, MRV demonstrated those plexuses better in some cases of cervical myelopathy; although this was not evaluated statistically. (author)

    Full Text Available Context: Preoperative severity of myelopathy, age, and duration of symptoms have been shown to be highly predictive of the outcome in compressive cervical myelopathy (CCM. The role of radiological parameters is still controversial. Aims: Define the prognostic factors in CCM and formulate a prognostic score to predict the outcome following surgery in CCM. Settings and Design: Retrospective. Materials and Methods: This study included 78 consecutive patients with CCM treated surgically. The modified Japanese Orthopaedic Association (mJOA scale was used to quantify severity of myelopathy at admission and at 12-month follow-up. The outcome was defined as "good" if the patient had mJOA score ≥16 and "poor" if the score was <16. Age, sex, duration of symptoms, comorbidities, intrinsic hand muscle wasting (IHMW, diagnosis, surgical technique, Torg ratio, instability on dynamic radiographs, and magnetic resonance imaging (MRI signal intensity changes were assessed. Statistics: Statistical Package for the Social Sciences (SPSS (version 20.0 was used for statistical analysis. The association was assessed amongst variables using logistic regression analysis. Parameters having a statistically significant correlation with the outcome were included in formulating a prognostic score. Results: Severity of myelopathy, IHMW, age, duration, diabetes, and instability on radiographs were predictive of the outcome with a P value <0.01. Genders, diagnosis, surgical procedure, Torg ratio, and intensity changes on MRI were not significantly related to the outcome. A 8-point scoring system was devised incorporating the significant clinicoradiological parameters, and it was found that nearly all patients (97.82% with a score below 5 had good outcome and all patients (100% with a score above 5 had poor outcome. The outcome is difficult to predict with a score of 5. Conclusions: Clinical parameters are better predictors of the outcome as compared to radiological findings

    In this study, 44 patients with the ossification of posterior longitudinal ligament, 34 men and 10 women, ranging in age from 38 to 76 years (mean 61) were investigated. They were classified into three categories by the cervical MRI sectional image, Boomerang-type, Triangle-type and Tear-drop-type, and the relationship between these three types and clinical symptom or the results of the surgery was examined. The patients in the Triangle-type were suffered for long term and had many lesions extended over whole interspines. As a result, their spinal cords were in the decrease in the cervical cross-sectional area, so-called in atrophy, and was not expected to improve cross-sectional area or the symptom even in postoperation. On the other hand, the Boomerang-type and the Tear-drop-type were suffered for relatively short term, had the lesion on single spine and were expected, in the excellent reversibility, to improve the cross-sectional area of the spinal cord and the symptom.

  2. Possible detection of cervical spondylotic neuropathy using Distribution of F-latency (DFL, a new neurophysiological parameter

    2010-04-01

    Full Text Available Abstract Background We have previously reported a new nerve conduction measurement parameter which we named the Distribution of F-latency (DFL and showed that this was an approximate mirror of the Distribution of Conduction Velocity (DCV of motor nerve fibers. This work was performed using measurements on the 20 median nerves from 10 volunteers. The DFL showed a number of different patterns including single peaks, broad peaks and double peaks, the latter observed on subjects with Cervical Spondylosis (CS. It was thought that a retrospective analysis of these data could be worthwhile in determining whether Cervical Spondylotic neuropathy could be detected using the DFL. Findings The DFL from the 8 median nerves of 4 normal subjects had single peaks, which has been assumed to represent a normal pattern. The DFL from one side of 5 subjects diagnosed with or suspected to have CS had double peaks. Broad peaks were observed in 7 nerves of which 5 were from subjects who had double peaks in the DFL on the contra lateral side. Conclusions Based on these findings, double peaks in the DFL appear to be associated with CS neuropathy. These findings further suggest that broad peaks in the DFL could indicate the early stages of the disease. Differential compression of nerve branches at the spinal roots are being explored as possible causes. This study does not preclude other pathologies contributing to double or broad peaks, but does suggest that the DFL could form a screening tool for CS neuropathy.

    Occasionally, the outcome from laminoplasty for cervical spondylosis is disappointing despite an adequate operation. Before surgery, it is difficult to diagnose the pathological extent of the involvement of the spinal cord. The purpose of this study is to determine the efficacy of magnetic resonance imaging (MRI) and of the motor evoked potentials (MEPs) for the indication of the surgery and prognosis. Retrospectively, we investigated the MEPs and the MRI of 31 patients in surgery for cervical myelopathy, involving 21 with cervical spondylosis and 10 with ossification of the posterior longitudinal ligamentum, and compared the findings from those with a poor outcome (n=3l) with the findings from those with a good outcome (n=32). The MEPs from the thenar muscle and the tibialis anterior were evoked by transcranial magnetic brain stimulation. In the poor-outcome patients, the spinal canal was narrow and lumbar spinal canal stenosis was seen in 5 cases which required lumbar laminectomy. Before operation, the MEPs from the thenar muscle could not be evoked in 5 cases while there was a remarkably prolonged central motor conduction time in the other 26 cases. MRI revealed the deformed spinal cord in the involved area, and the signal intensity of the involved spinal cord in the T2 weighted image was remarkably high. The signal intensity ratio was significantly higher in the poor-outcome patients than in the good-outcome patients. This study suggested that a high signal intensity in the T2 weighted image and a prolonged conduction time or absence of MEPs largely corresponded to the clinical and other investigative features of myelopathy responsible for a poor outcome.

    Full Text Available Background and Aims: We have utilized lift-up laminoplasty to treat patients with myelopathy caused by ossification of the posterior longitudinal ligament (OPLL of the cervical spine. The preliminary surgical outcome with computer-assisted morphological assessment is presented. Material and Methods: The surgical technique of lift-up laminoplasty includes standard posterior exposure of the cervical spine, en-bloc laminectomy, and expansion of the cervical canal by lift-up of the laminae with custom-designed hydroxyapatite laminar spacers and stabilization of the laminae using titanium miniplates. From 1998 to 2003, 10 consecutive patients with cervical myelopathy secondary to OPLL have been treated with this method and comprehensively evaluated. Care was taken to tailor the treatment to individual patients by using different sizes of spacers to adjust the degree of expansion depending on the amount of stenosis of the cervical spine. The degree of expansion of the cervical canal was altered by design, based on the preoperative imaging simulation. Results: Preliminary surgical outcome, evaluated at 6 months after surgery, revealed a significant improvement of neurological function. Image analysis revealed that the cervical canals were significantly expanded, with a mean reduction of 13.1% in the stenosis ratio. Lift-up laminoplasty was effective in the treatment of patients with myelopathy secondary to cervical OPLL, and the amount of expansion could be individually adjusted at the discretion of the surgeon. Conclusion: Although analysis with a larger population and a longer follow-up period needs to be undertaken, our method of lift-up laminoplasty appears to be a viable choice among standard posterior cervical approaches for cervical OPLL.

    Purpose: Intervertebral cervical disc herniation (CDH) is a relatively common disorder that can coexist with degenerative changes to worsen cervicogenic myelopathy. Despite the frequent disc abnormalities found in asymptomatic populations, magnetic resonance imaging (MRI) is considered excellent at detecting cervical spine myelopathy (CSM) associated with disc abnormality. The objective of this study was to investigate the intra- and inter-observer reliability of MRI detection of CSM in subjects who also had co-existing intervertebral disc abnormalities. Materials and methods: Seven experienced radiologists reviewed twice the MRI of 10 patients with clinically and/or imaging determined myelopathy. MRI assessment was performed individually, with and without operational guidelines. A Fleiss Kappa statistic was used to evaluate the intra- and inter-observer agreement. Results: The study found high intra-observer percent agreement but relatively low Kappa values on selected variables. Inter-observer reliability was also low and neither observation was improved with operational guidelines. We believe that those low values may be associated with the base rate problem of Kappa. Conclusion: In conclusion, this study demonstrated high intra-observer percent agreement in MR examination for intervertebral disc abnormalities in patients with underlying cervical myelopathy, but differing levels of intra- and inter-observer Kappa agreement among seven radiologists.

  6. Outcomes of conservative treatment for cervical myelopathy caused by soft disc herniation

    International Nuclear Information System (INIS)

    The purposes of this study are to delineate the clinical course and MRI findings of patients with disc hernias which regressed spontaneously and to determine who is eligible for conservative treatment. Twenty-three patients with mild cervical myelopathy (initial Japanese Orthopedic Association (JOA) scores >10) caused by soft disc herniation were treated conservatively for more than two years (13 males, 10 females, mean age 50, mean follow-up 3.6 years). The investigated items included JOA scores and MRI findings (morphology of disc herniation). Morphology of disc herniation was classified into focal type (herniated mass persisting at the intervertebral level) and diffuse type (herniated mass migrating rostrally or caudally) in the sagittal plane and median type or paramedian type in the axial plane. The mean JOA scores were 13.4±1.5 before treatment, and 16.0±1.0 at follow-up. Regression of herniation was observed in 14 patients (Group A), while no regression was seen in 9 patients (Group B). The JOA scores were 13.7±1.5 (Group A) and 14.0±1.6 (Group B) before treatment, and 16.3±1.6 and 15.7±1.2 at follow-up, respectively. On sagittal MR images, diffuse-type herniation was observed in 9 patients (64%) and focal-type in 5 (36%) in Group A, and 3 (33%) and 6 (67%) in Group B, respectively. On axial images, median-type herniation was observed in 10 patients (71%), and paramedian-type in 4 (29%) in Group A, and 6 (67%) and 3 (33%) in Group B, respectively. Spontaneous soft disc regression in patients with cervical myelopathy was observed in more than half of those treated conservatively for longer than 2 years. Conservative treatment can be recommended for patients with mild cervical myelopathy, especially when caused by median-and/or diffuse-type disc hernia, although close observation is mandatory.

    This study reports on a 70-year-old man with recurrent cervical myelopathy 20 years after anterior decompression and fusion of C4-7 using a free vascularised strut graft. The recurrent myelopathy was secondary to a kyphotic deformity of a fractured graft and residual ossification of the posterior longitudinal ligament with stenosis at C3/4. Intraoperative spinal cord-evoked potentials indicated that spinal cord traction secondary to progressive kyphosis of the cervical spine after the graft fracture was the cause. The patient underwent laminoplasty at C3 and laminectomy at C4 to decompress the stenosis at C3/4 as well as posterior cervical spinal fusion at C3-7 with pedicle screws and a lateral mass screw and a bone graft to prevent further progression of the kyphosis. At postoperative 18 months, the patient's Japanese Orthopaedic Association score had improved to 14 from 8, and he could walk without support. PMID:26321562

    2015-08-01

    Full Text Available Cervical vertebral stenotic myelopathy (CVSM, also known as cervical ataxia or wobbler syndrome, is caused by the narrowing of the medullary canal due to a malformation of the cervical vertebrae, resulting in compression of the spinal cord and neurological alterations such as ataxia, hypermetria, weakness, and abnormal stance. The treatment options can be conservative or surgical, with varied effectiveness. The most appropriate surgical technique in the majority of cases is arthrodesis, providing quick and efficient decompression of the spinal cord. The goal of this case report is to present an equine patient with CVSM that was surgically treated using a new modified cage model. The diagnosis was based on history, clinical signs and radiographic evidence of spinal cord compression between the C3 and C4 vertebrae, after ruling out possible infectious agents. The surgical procedure for the decompression and stabilization of the point of stenosis was performed using a modified Cloward’s technique and a new cage model fixed with two screws. Evidence of fusion was obtained by periodic radiographs over six months of postoperative care. The new cage model used in this surgery proved to be efficient for the decompression and stabilization of the vertebrae, allowing arthrodesis development and remission of the clinical signs. Fixation of the cage with screws reduces the risk of migration of the implant.

    Study Design Single-center retrospective study. Purpose To clarify the clinical features of cervical myelopathy at the C1–2 level. Overview of Literature Methods for distinguishing the affected level based on myelomere symptoms or dysfunction of the conducting pathway were established. However, no symptoms have been identified as being specific to the C1–2 level segment. Methods We evaluated 24 patients with cervical myelopathy due to spinal cord compression at the C1–2 level. Preoperative neurological assessment were investigated and compared with the rate and site of compression of the spinal cord using computed tomography-myelography. Results Impaired temperature and pain sensation were confirmed in 18 of the 24 patients with that localized to the upper arms (n=3), forearm (n=9), both (n=2), and whole body (n=4). Muscle weakness was observed in 18 patients, muscle weakness extended from the biceps brachii to the abductor digiti minimi in 10 patients, and in the whole body in 8 patients. Deep tendon reflexes were normal in 10 patients, whereas hyperactive deep tendon reflexes were noted in 14 patients. The rate of spinal cord compression was significantly higher in patients with perceptual dysfunction and muscle weakness compared with those with no dysfunction. However, no significant difference in the rate and site of compression was identified in those with dysfunction. Conclusions Perceptual dysfunction and muscle weakness localized to the upper limbs was observed in 58% and 42% of patients, respectively. Neurological abnormalities, such as perceptual dysfunction and muscle weakness, were visualized in patients with marked compression.

    This is a meta-analysis to compare the results between laminoplasty and laminectomy followed by fusion for the patients with multilevel cervical compressive myelopathy. An extensive search of literature was performed in MEDLINE, Embase, the Cochrane library, CNKI, and WANFANG. The following outcome measures were extracted: the Japanese Orthopaedic Association (JOA) scores, cervical curvature index (CCI), visual analog scale (VAS), cervical lordosis (C2-7), complications, blood loss, and operation time. Data analysis was conducted with RevMan 5.3 and STATA 12.0. A total of 23 studies comprising 774 and 743 patients treated with laminoplasty and laminectomy followed by fusion, respectively, were included in the final analysis. The pooled analysis showed that there was no significant difference in preoperative JOA scores [P = 0.89], postoperative JOA scores [P = 0.13], JOA scores improvement rate [P = 0.27], preoperative CCI [P = 0.15], postoperative CCI [P = 0.14], preoperative VAS [P = 0.41], postoperative VAS [P = 0.52], preoperative cervical lordosis (C2-7) [P = 0.46], postoperative cervical lordosis (C2-7) [P = 0.67], total complications [P = 0.07], axial pain [P = 0.94], and blood loss [P = 0.51]. However, there were significant difference in operation time (WMD = -19.57 [-32.11, -7.02], P = 0.002) and C5 palsy (OR = 0.26 [0.15, 0.44], P lordosis (C2-7), axial pain, total complications, and blood loss, but shorter operation time and fewer C5 palsy.

    Full Text Available We aim to evaluate the impact of age and duration of symptoms on surgical outcome of the patients with cervical spondylotic radiculopathy (CSR who had been treated by single-level microscopic anterior cervical discectomy and fusion (ACDF. We retrospectively evaluated 68 patients (48 female and 20 male with a mean age of 41.2±4.3 (ranged from 24 to 72 years old in our Orthopedic Department, Imam Reza Hospital. They were followed up for 31.25±4.1 months (ranged from 25 to 65 months. Pain and disability were assessed by Visual Analogue Scale (VAS and Neck Disability Index (NDI questionnaires in preoperative and last follow-up visits. Functional outcome was eventually evaluated by Odom’s criteria. Surgery could significantly improve pain and disability from preoperative 6.2±1.4 and 22.2±6.2 to 3.5±2.0 and 8.7±5.2 (1–21 at the last follow-up visit, respectively. Satisfactory outcomes were observed in 89.7%. Symptom duration of more and less than six months had no effect on surgical outcome, but the results showed a statistically significant difference in NDI improvement in favor of the patients aged more than 45 years (P=0.032, although pain improvement was similar in the two groups.

    Full Text Available Aims and objectives: To assess the efficacy and results of expansive laminoplasty in advanced (Nurick's Grade III or greater cervical myelopathy. Materials and Methods: We reviewed data in 24 patients who underwent cervical laminoplasty from January 1999 to December 2002. Nuricks grading was used for quantifying the neurological deficits and outcome analysis was done using Odom's criteria. A modified Hirabayashi's open door laminoplasty was done using Titanium miniplates and screws in 22 patients, autologous bone in one and hydroxyapatite spacer in one patient. Observations: There were 3 females and 21 males with a mean age of 56 years (range 39-72 years. Four patients presented in Nuricks Grade III, 15 in Grade IV and five in Grade V. MR imaging showed MSCS in 21 cases, OPLL in nine cases and ligamentum flavum hypertrophy in nine cases with cord signal changes being present in 19 cases. Results: All patients with duration of symptoms less than three years, and 50 % with duration ranging from three to six years had improvement by at least one Nurick's grade following surgery. Eighty-seven per cent Grade IV patients (ambulatory with support improved to Grade III (ambulatory without support following laminoplasty. Using Odom's criteria, 23 patients (95.8% had a good to fair outcome. Conclusions: Cord decompression with expansive laminoplasty using titanium miniplate fixation may improve the neurological outcome even in patients presenting late, and improvement by even one grade may have major 'quality of life' benefits for these patients.

    In this case report, methods to accomplish differential diagnosis for Cervical Stenotic Myelopathy with other diseases with similar symptomatology are described. Cervical Stenotic Myelopathy is an affection characterized by the narrowing of the cervical vertebrae canal, causing a spinal cord compression. This abnormality usually results of a cervical vertebral malformation during the development of the animal. Nutritional imbalances are straightly related to the development of this syndrome. Genetic influence is also described as an etiologic factor. In spite of being an orthopedic disease, it appears through nervous symptomatology, as a result of the spinal cord compression. Thus, the accomplishment of differential diagnosis is necessary for traumatic lesions, Equine Protozoal Mieloencephalitis, Equine Herpesvirus Mieloencephalitis and Equine Degenerative Mieloencephalitis. In this study diagnosis methods, like radiography and myelogram, were used to detect Cervical Stenotic Myelopathy in 7 Thoroughbred horses. The simple radiological examination showed disorders at the bone conformation, while the myelogram was important in the recognition of the site of spinal cord compression. The histopathological examination was conclusive on the detection of spinal cord compressive lesions.

    Klippel-Feil syndrome (KFS) is a congenital developmental disorder of cervical spine, showing short neck with restricted neck motion, low hairline, and high thoracic cage due to multilevel cervical fusion. Radiculopathy or myelopathy can be accompanied. There were 2 patients who were diagnosed as KFS with exhibited radiological and physical characteristics. Both patients had stenosis and cord compression at C1 level due to anterior displacement of C1 posterior arch secondary to kyphotic deformity of upper cervical spine, which has been usually indicative to craniocervical fixation. One patient was referred due to quadriparesis detected after surgery for aortic arch aneurysmal dilatation. The other patient was referred to us due to paraparesis and radiating pain in all extremities developed during gynecological examinations. Decompressive C1 laminectomy was done for one patient and additional suboccipital craniectomy for the other. No craniocervical fixation was done because there was no spinal instability. Motor power improved immediately after the operation in both patients. Motor functions and spinal stability were well preserved in both patients for 2 years. In KFS patients with myelopathy at the C1 level without C1-2 instability, a favorable outcome could be achieved by a simple decompression without spinal fixation. PMID:26512291

    OBJECTIVE—To report the efficacy of conservative treatment with cervical traction and immobilisation with a Halo vest, in two consecutive rheumatoid arthritis patients with progressive cervical myelopathy caused by subaxial subluxation.
METHODS—Description of neurological symptoms and signs and findings in plain radiography (PR) and magnetic resonance imaging (MRI) of the cervical spine before and after treatment of the subaxial subluxation by traction and immobilisation with a Halo vest during four months.
RESULTS—During four months of traction and immobilisation neurological examination showed a considerable improvement of the signs and symptoms of cervical myelopathy. Afterwards PR and MRI of the cervical spine showed reduction of the subaxial subluxation. Eventually firm stabilisation was obtained in both patients without surgery of the cervical spine.
CONCLUSION—Cervical traction and immobilisation with a Halo vest can be considered as an independent conservative treatment in rheumatoid arthritis patients with cervical myelopathy caused by subaxial subluxation.

    2015-01-01

    Introduction. Flexion-extension, or kinematic, MRI has been used to identify dynamic spondylotic spinal cord compression not seen with traditional static MRI. The use of kinematic MRI to diagnose postoperative complications, specifically dynamic compression, is not as well documented. The authors describe a case of dynamic spinal cord compression by the paraspinal muscles causing worsening myelopathy following cervical laminectomy. This was only diagnosed with flexion-extension MRI. Methods. The patient was a 90-year-old male presenting to the neurosurgery clinic with functional decline and cervical spondylotic myelopathy. Results. A multilevel laminectomy was performed. Following surgery the patient had progressive weakness and worsening myelopathy. No active cord compression was seen on multiple MRIs obtained in a neutral position, and flexion-extension X-rays did not show instability. A kinematic MRI demonstrated dynamic compression of the spinal cord only during neck extension, by the paraspinal muscles. To relieve the compression, the patient underwent an instrumented fusion, with cross-links used to buttress the paraspinal muscles away from the cord. This resulted in neurologic improvement. Conclusions. We describe a novel case of spinal cord compression by paraspinal muscles following cervical laminectomy. In individuals with persistent myelopathy or delayed neurologic decline following posterior decompression, flexion-extension MRI may prove useful in diagnosing this potential complication.

    Atlanto-occipital assimilation is one of the most common osseous anomalies observed at the craniocervical junction. Most patients with atlas assimilation show no symptom, but some have neurological problems such as myelopathy that may require surgical treatment. Occipitocervical fusion may be required if atlato-occipital assimilation is accompanied by occipito-axial instability. However, in cases of symptomatic atlas assimilation with minor cord compression without instability, simple decompr...

    2014-01-01

    Full Text Available Background: Ossification of the posterior longitudinal ligament (OPLL and cervical disc herniation are commonly encountered neurosurgical conditions. Here we present an unusual case of nontraumatic rapidly progressive myelopathy due to cervical disc herniation with comorbid OPLL and conduct a literature review focusing on the frequency and management of disc herniations with OPLL. Case Description: A 52-year-old healthy female presented with a 72-h history of rapid progression of dense quadriparesis with sensory deficits, with a precedent 4-week history of nontraumatic midline neck pain. Clinical examination revealed profound motor deficits below the C5 myotome. Spinal neuroimaging revealed OPLL (computed tomography [CT] and a cervical disc herniation spanning from C4/5 to C5/6 with significant retrovertebral disease (magnetic resonance imaging [MRI]. Operative management involved an anterior cervical corpectomy and instrumented fusion, with removal of both the sequestered disc material and the locally compressive OPLL. The patient recovered full motor function and independent ambulation with no residual signs or symptoms of myelopathy at the time of discharge. Conclusion: This unique case of a spontaneous cervical disc herniation in the context of OPLL causing rapidly progressive myelopathy illustrates the complementarity of CT and MRI in diagnosing the underlying cause of a rapidly progressive neurologic deficit in the absence of antecedent trauma. Though the optimal surgical management of such pathology remains uncertain; in this case, the anterior approach was motivated by the significant retrovertebral ventrally compressive sequestrum, and provided for excellent neurologic outcome. This article also reviews the occurrence/management of such acute cervical discs with OPLL.

    2012-01-01

    Full Text Available Myelopathy at the level of the atlas is rarely encountered by the practicing spine surgeon. Due to the region's unique anatomy, compression of the cord at this level is either caused by a large compressing lesion or an abnormally stenotic canal. We describe a rare instance of a congenitally stenotic canal due to a hypoplastic intact posterior arch of atlas, coexisting with an extremely rare ossified transverse ligament of the atlas. The coexistence of these two lesions has only been documented thrice before. We describe the clinical presentation, imaging findings, and favorable response to surgery.

    Objective: Spinal cord swelling with abnormal gadolinium (Gd) enhancement is a rare preoperative radiological finding in patients with cervical spondylosis. In the presence of progressive myelopathy, timely surgical decompression can be curative. Case presentation: We report 3 patients with cervical spondylotic myelopathy. Preoperative magnetic resonance imaging (MRI) revealed spondylotic changes and intramedullary lesions in the cervical spine. We noted cervical cord swelling with high intensity on T2-weighted MRI and abnormal Gd-DTPA enhancement. Laminoplasty resulted in marked improvement of their neurological condition and postoperative MRI revealed gradual regression of the intramedullary lesions during the first year. Conclusion: We posit that the intramedullary lesions in our patients were reflective of spinal cord edema with blood-brain-barrier disturbance in the cervical cord, possibly due to minor recurrent spinal cord injury and disturbed venous circulation. Spinal cord edema is a rare condition in patients with cervical spondylosis and an accurate diagnosis and timely surgery are necessary for cure. Therefore, this unusual condition must be considered in spondylosis patients manifesting as intramedullary lesions on MRI of the cervical spinal cord. Careful evaluation of the postoperative course can be used to confirm the diagnosis and help in selecting a subsequent therapeutic strategy. PMID:22028753

    This study evaluated the contribution of computed tomographic discography (CTD) to the surgical indications and selection of surgical techniques in cervical disc herniation. The study population consisted of 73 patients who were diagnosed as having cervical disc herniation by CTD: Of them, hernia mass was confirmed by surgery in 64 patients (a concordance rate of 88% between CTD and surgical findings). In evaluable 40 patients receiving computed tomographic myelography (CTM), the rate of flattened spinal cord on CTM was significantly correlatd with postoperative prognosis. Flattened spinal cord was favorably improved. Higher preoperative flat rate was associated with severer cervical disc herniation. CTD provided the information concerning the positional relation in the posterior longitudinal ligament of hernia mass. Preoperative severity, preoperative rate of flattened spinal cord, and the site of protrusion of hernia mass were independent of surgical outcome. (N.K.).

    OBJECTIVE The minimum clinically important difference (MCID) is defined as the minimum change in a measurement that a patient would identify as beneficial. Before undergoing surgery, patients are likely to inquire about the ultimate goals of the operation and of their chances of experiencing meaningful improvements. The objective of this study was to define significant predictors of achieving an MCID on the modified Japanese Orthopaedic Association (mJOA) scale at 2 years following surgery for the treatment of degenerative cervical myelopathy (DCM). METHODS Seven hundred fifty-seven patients were prospectively enrolled in either the AOSpine North America or International study at 26 global sites. Fourteen patients had a perfect preoperative mJOA score of 18 and were excluded from this analysis (n = 743). Data were collected for each participating subject, including demographic information, symptomatology, medical history, causative pathology, and functional impairment. Univariate log-binominal regression analyses were conducted to evaluate the association between preoperative clinical factors and achieving an MCID on the mJOA scale. Modified Poisson regression using robust error variances was used to create the final multivariate model and compute the relative risk for each predictor. RESULTS The sample consisted of 463 men (62.31%) and 280 women (37.69%), with an average age of 56.48 ± 11.85 years. At 2 years following surgery, patients exhibited a mean change in functional status of 2.71 ± 2.89 points on the mJOA scale. Of the 687 patients with available follow-up data, 481 (70.01%) exhibited meaningful gains on the mJOA scale, whereas 206 (29.98%) failed to achieve an MCID. Based on univariate analysis, significant predictors of achieving the MCID on the mJOA scale were younger age; female sex; shorter duration of symptoms; nonsmoking status; a lower comorbidity score and absence of cardiovascular disease; and absence of upgoing plantar responses, lower

    Full Text Available In patients with cervical spondylotic myelopathy MRI sometimes shows increased signal intensity zones on the T2-weighted images. It has been suggested that these findings carry prognostic significance. We studied 56 subjects with cervical spinal cord compression. Twelve patients showed an increased signal intensity (21.4% and a prevalence of narrowing of the AP-diameter (62% vs 24%. Furthemore, in this group, there was evidence of a longer mean duration of the symptoms and, in most of the patients, of more serious clinical conditions. The importance of these predisposing factors remains, however, to be clarified since they are also present in some patients without the increased signal intensity.

  13. Morphometrical study of the axial view of the cervical spinal cord with MRI. Analysis of the normal shape and relation between the shape of the spinal cord and the clinical result in compression myelopathy

    International Nuclear Information System (INIS)

    The axial view of normal cervical spinal cord was analyzed to elucidate the relationships between its shape and clinical result in compression myelopathy. Subjects were 104 cases with normal shape and 35 cases with cervical myelopathy of a single intervertebral compressive lesion. MRI was performed with General Electric 1.5 T superconducting apparatus to get T1-weighted cross image of 5 mm slice thickness. Morphometry was performed with high performance image processor (SPICCA, Nihon-Avionics) to compute the area and longitudinal and lateral lengths of spinal cord to calculate flatness. The area and longitudinal length were positively correlated with body height, and the longitudinal length and flatness, negatively with age. The reduction rate of the spinal cord area had a relation with neurological symptoms, but, together with age and duration of the disease, had no relation with the clinical results from operation.

    Background Cervical compressive myelopathy, e.g. due to spondylosis or ossification of the posterior longitudinal ligament is a common cause of spinal cord dysfunction. Although human pathological studies have reported neuronal loss and demyelination in the chronically compressed spinal cord, little is known about the mechanisms involved. In particular, the neuroinflammatory processes that are thought to underlie the condition are poorly understood. The present study assessed the localized pr...

    {sup 18}F-FDG PET is used to investigate the metabolic activity of neural tissue. MRI is used to visualize morphological changes, but the relationship between intramedullary signal changes and clinical outcome remains controversial. The present study was designed to evaluate the use of 3-D MRI/{sup 18}F-FDG PET fusion imaging for defining intramedullary signal changes on MRI scans and local glucose metabolic rate measured on {sup 18}F-FDG PET scans in relation to clinical outcome and prognosis. We studied 24 patients undergoing decompressive surgery for cervical compressive myelopathy. All patients underwent 3-D MRI and {sup 18}F-FDG PET before surgery. Quantitative analysis of intramedullary signal changes on MRI scans included calculation of the signal intensity ratio (SIR) as the ratio between the increased lesional signal intensity and the signal intensity at the level of the C7/T1 disc. Using an Advantage workstation, the same slices of cervical 3-D MRI and {sup 18}F-FDG PET images were fused. On the fused images, the maximal count of the lesion was adopted as the standardized uptake value (SUV{sub max}). In a similar manner to SIR, the SUV ratio (SUVR) was also calculated. Neurological assessment was conducted using the Japanese Orthopedic Association (JOA) scoring system for cervical myelopathy. The SIR on T1-weighted (T1-W) images, but not SIR on T2-W images, was significantly correlated with preoperative JOA score and postoperative neurological improvement. Lesion SUV{sub max} was significantly correlated with SIR on T1-W images, but not with SIR on T2-W images, and also with postoperative neurological outcome. The SUVR correlated better than SIR on T1-W images and lesion SUV{sub max} with neurological improvement. Longer symptom duration was correlated negatively with SIR on T1-W images, positively with SIR on T2-W images, and negatively with SUV{sub max}. Our results suggest that low-intensity signal on T1-W images, but not on T2-W images, is correlated

    Full Text Available Abstract Background It has been stated that individuals who have spondylotic encroachment on the cervical spinal cord without myelopathy are at increased risk of spinal cord injury if they experience minor trauma. Preventive decompression surgery has been recommended for these individuals. The purpose of this paper is to provide the non-surgical spine specialist with information upon which to base advice to patients. The evidence behind claims of increased risk is investigated as well as the evidence regarding the risk of decompression surgery. Methods A literature search was conducted on the risk of spinal cord injury in individuals with asymptomatic cord encroachment and the risk and benefit of preventive decompression surgery. Results Three studies on the risk of spinal cord injury in this population met the inclusion criteria. All reported increased risk. However, none were prospective cohort studies or case-control studies, so the designs did not allow firm conclusions to be drawn. A number of studies and reviews of the risks and benefits of decompression surgery in patients with cervical myelopathy were found, but no studies were found that addressed surgery in asymptomatic individuals thought to be at risk. The complications of decompression surgery range from transient hoarseness to spinal cord injury, with rates ranging from 0.3% to 60%. Conclusion There is insufficient evidence that individuals with spondylotic spinal cord encroachment are at increased risk of spinal cord injury from minor trauma. Prospective cohort or case-control studies are needed to assess this risk. There is no evidence that prophylactic decompression surgery is helpful in this patient population. Decompression surgery appears to be helpful in patients with cervical myelopathy, but the significant risks may outweigh the unknown benefit in asymptomatic individuals. Thus, broad recommendations for decompression surgery in suspected at-risk individuals cannot be made

    Myelopathy secondary to radiation is a relatively uncommon entity which was reported initially in 1941 by Ahlbom. From a total of 65 patients who were seen in our spinal injury clinic during the past four years, three patients have received a diagnosis of radiation myelopathy. This is 4.6 percent of the total number. The case histories of two patients with radiation myelopathy are presented. The clinical and pathologic features are discussed. Since the three patients with this diagnosis whose cases are followed in the clinic are still alive, the second case that is reported is taken from the files of the pathology department so that autopsy and histologic data also can be presented.

    Full Text Available Background: Hirayama disease (HD is benign focal amyotrophy of the distal upper limbs, often misdiagnosed as motor neuron disease. Routine magnetic resonance imaging (MRI is often reported normal. Objective: To study the clinicoradiological profile of hand wasting in young males. Materials and Methods: Patients presenting with insidious-onset hand wasting from March 2008 to May 2011 were evaluated electrophysiologically. Cervical MRI in neutral position was done in 11 patients and flexion contrast imaging was done in 10 patients. Results: All patients were males less than 25 years of age, with median age 23 years, except one patient who was 50 years old. Duration of illness was 3 months to 3 years. All (100% had oblique amyotrophy, four (36% cold paresis, 10 (91% minipolymyoclonus and three (27% had fasciculations. Regional reflexes were variably absent. Two patients (18% had brisk reflexes of lower limbs with flexor plantars. Electromyography (EMG showed chronic denervation in the C7-T1 myotomes. Neutral position MRI showed loss of cervical lordosis in 10/11 (91%, localized lower cervical cord atrophy in 9/11 (82%, asymmetric cord flattening in 11/11 (100% and intramedullary hyperintensity in 2/11 (18%; flexion study showed loss of dural attachment, anterior displacement of dorsal dura, epidural flow voids in 9/10 (90% and enhancing epidural crescent in 10/10 (100%. Clinical profile, imaging and electrophysiological findings of the patient aged 50 years will be described in detail as presentation at this age is exceptional. Collar therapy slowed progression in most cases. Conclusion: Clinical features of HD corroborated well with electrophysiological diagnosis of anterior horn cell disease of lower cervical cord.

    Background In general, older patients with degenerative cervical myelopathy (DCM) are felt to have lower recovery potential following surgery due to increased degenerative pathology, comorbidities, reduced physiological reserves and age-related changes to the spinal cord. This study aims to determine whether age truly is an independent predictor of surgical outcome and to provide evidence to guide practice and decision-making. Methods A total of 479 patients with DCM were prospectively enrolled in the CSM-International study at 16 centres. Our sample was divided into a younger group (<65 years) and an elderly (≥65 years) group. A mixed model analytic approach was used to evaluate differences in the modified Japanese Orthopaedic Association (mJOA), Nurick, Short Form-36 (SF-36) and Neck Disability Index (NDI) scores between groups. We first created an unadjusted model between age and surgical outcome and then developed two adjusted models that accounted for variations in (1) baseline characteristics and (2) both baseline and surgical factors. Results Of the 479 patients, 360 (75.16%) were <65 years and 119 (24.84%) were ≥65 years. Elderly patients had a worse preoperative health status (p<0.0001) and were functionally more severe (p<0.0001). The majority of younger patients (64.96%) underwent anterior surgery, whereas the preferred approach in the elderly group was posterior (58.62%, p<0.0001). Elderly patients had a greater number of decompressed levels than younger patients (p<0.0001). At 24 months after surgery, younger patients achieved a higher postoperative mJOA (p<0.0001) and a lower Nurick score (p<0.0001) than elderly patients. After adjustments for patient and surgical characteristics, these differences in postoperative outcome scores decreased but remained significant. Conclusions Older age is an independent predictor of functional status in patients with DCM. However, patients over 65 with DCM still achieve functionally significant

    Anterior cervical discectomy and fusion, to date the most successful spine procedure for the surgical treatment of cervical radiculopathy, has limitations that have led to the development of non-fusion cervical procedures, such as cervical total disc replacement (TDR) and dynamic cervical implant (DCI) arthroplasty. We compared the clinical and radiological results of DCI and cervical TDR for the treatment of single-level cervical degenerative disc disease in Chinese patients. A retrospective review of 179 patients with cervical spondylotic myelopathy who underwent DCI or TDR between April 2010 and October 2012 was conducted, and 152 consecutive patients (67 patients single-level DCI and 85 single-level TDR) who completed at least 2years of follow-up were included. Clinical and radiological assessments were performed preoperatively and at 1week and 3, 6, 12, and 24months postoperatively. The most common operative level was C5/C6 (49.3%). The differences in blood loss, duration of surgery, and duration of hospitalization were not statistically significant. The Japanese Orthopaedic Association scale, Visual Analog Scale, Neck Disability Index, and Short Form-36 scores improved significantly after surgery in both the DCI and TDR groups (P<0.05), but the differences were not statistically significant at the final follow-up. The rate of occurrence of heterotopic ossification was 22.4% and 28.2% in the DCI and TDR groups, respectively. As an effective non-fusion technique, DCI is a more economical procedure. Further prospective, randomized studies with long-term follow-up periods are needed to determine the long-term effects. PMID:26928156

    2012-01-01

    Full Text Available We report a patient with congenital anomaly of cervical spine, who presented with clinical features suggestive of cervical compressive spondylotic myelopathy. He underwent C3 median corpectomy, graft placement, and stabilization from C2 to C4 vertebral bodies. Postoperative period was uneventful and he improved in his symptoms. Eight years later, he presented with a difficulty in swallowing and occasional regurgitation of feeds of 2 months duration and oral extrusion of screw while having food. On oral examination, there was a defect in the posterior pharyngeal wall through which the upper end of plate with intact self-locking screw and socket of missed fixation screw was seen. This was confirmed on X-ray cervical spine. He underwent removal of the plate system and was fed through nasogastric tube and managed with appropriate antibiotics. This case is presented to report a very rare complication of anterior cervical plate fixation in the form of very late-onset dislodgement, migration of anterior cervical plate, and oral extrusion of screw through perforated posterior pharyngeal wall.

    de 200 pacientes sometidos a tratamiento quirúrgico de la mielorradiculopatía cervical en el HC-FMUSP, desde enero de 1993 a enero de 2007. La evaluación clínica se cuantificó mediante la escala de la JOA, con un segmento promedio de 06 años y 08 meses. RESULTADOS: Se observó una mejoría neurológica posoperatoria en las vías anterior y posterior, con excepción de las laminectomías sin fusión, donde hubo deterioro neurológico tardío. La vía anterior mostró una tasa significativamente mayor de complicaciones relacionadas con el déficit de fusión intervertebral, desplazamiento del injerto, síndrome de disco adyacente, disfonía, disfagia, o mala posición de injerto y placas, lesión de la raíz del nervio y tasa significativamente mayor de nueva intervención quirúrgica. En la vía posterior, mayor incidencia de inestabilidad en la cifosis posoperatoria, en la laminectomía, y en la laminoplastia no se observó esto, teniendo esta última tasas similares a las encontradas en la vía anterior. No hubo mejoría en el dolor axial en las laminoplastias y se agravó en las laminectomías, mientras que en las discectomías y las corpectomías se produjo una mejoría significativa de los síntomas. CONCLUSIÓN Las vías anterior y posterior fueron eficaces en la producción de mejoría neurológica, con excepción de las laminectomías sin fusión. La vía anterior produjo más complicaciones, pero el dolor es mejor tratado.OBJECTIVE: To evaluate the efficacy of surgical treatment of cervical spondylotic myeloradiculopathy in the production of postoperative neurological improvement, measured in points by the scale of JOA (Japanese Orthopaedic Association and the recovery rate and complications of therapy.

    Full Text Available Movement disorders secondary to intrinsic spinal cord disease are rare. Paroxysmal chorea has not yet been reported in the neuromyelitis optica (NMO. We report a 43-year-old woman with relapsing-remitting cervical myelopathy who developed paroxysmal chorea during clinical exacerbation of NMO. MRI scan of the cervical spine revealed a long segmental enhancing lesion, but brain MRI did not show any responsible abnormalities. Acute exacerbation of recurrent myelopathy in NMO may be associated with transient movement disorder.

    2016-01-01

    Hereditary and metabolic myelopathies are a heterogeneous group of neurologic disorders characterized by clinical signs suggesting spinal cord dysfunction. Spastic weakness, limb ataxia without additional cerebellar signs, impaired vibration, and positional sensation are hallmark phenotypic features of these disorders. Hereditary, and to some extent, metabolic myelopathies are now recognized as more widespread systemic processes with axonal loss and demyelination. However, the concept of predominantly spinal cord disorders remains clinically helpful to differentiate these disorders from other neurodegenerative conditions. Furthermore, metabolic myelopathies are potentially treatable and an earlier diagnosis increases the likelihood of a good clinical recovery. This chapter reviews major types of degenerative myelopathies, hereditary spastic paraplegia, motor neuron disorders, spastic ataxias, and metabolic disorders, including leukodystrophies and nutritionally induced myelopathies, such as vitamin B12, E, and copper deficiencies. Neuroimaging studies usually detect a nonspecific spinal cord atrophy or demyelination of the corticospinal tracts and dorsal columns. Brain imaging can be also helpful in myelopathies caused by generalized neurodegeneration. Given the nonspecific nature of neuroimaging findings, we also review metabolic or genetic assays needed for the specific diagnosis of hereditary and metabolic myelopathies. PMID:27430441

    Myelopathy describes any neurologic deficit related to the spinal cord. It is most commonly caused by its compression by neoplasms, degenerative disc disease, trauma, or infection. Less common causes of myelopathy include spinal cord tumors, infection, inflammatory, neurodegenerative, vascular, toxic, and metabolic disorders. Conditions affecting the spinal cord must be recognized as early as possible to prevent progression that may lead to permanent disability. Biopsy is rarely performed, thus the diagnosis and management rely on patient׳s history, physical examination, laboratory results, and imaging findings. Here we review the clinical presentations, pathophysiological mechanisms, and magnetic resonance imaging findings of myelopathies related to metabolic or toxic etiologies. PMID:27616316

    Full Text Available The association between motor tics and cervical myelopathy is rare and not well understood. Only a few papers in the literature reported this disorder until the present date. This is a case report of a cervical myelopathy case secondary to a motor tic disorder. A 23-year-old male with a 10-year history of motor tic disorder, involving sudden forced extension of the head and cervical spine. Disturbed tactile sensation and kinetic posturing that progressed to the Lhermitte sign every time he made the movement were detected over the last six months. Magnetic resonance imaging (MRI showed hyperintense intramedullary lesion at C2-C3, degeneration at C3-C4, and no signs of spinal cord compression. On sagittal view, functional MRI with head extension showed anterior compression with protrusion of the intervertebral disc and posterior compression of the yellow ligaments causing spinal cord stenosis. Anterior discectomy and fixation of C3-C4 were performed. There were no complications. The patient showed improvement and the motor tics were controlled by haloperidol. The patient remains symptom-free after 2 years of follow-up. Uncontrolled motor tics can compromise spinal cord function. Functional MRI can reproduce the abnormal movements and clarify the physiopathology.La asociación entre tics motores y mielopatía cervical es rara y no es bien comprendida. Pocos estudios, que analizan este disturbio, han sido encontrados en la literatura hasta el momento. Este es el relato de un caso de mielopatía cervical secundaria a tics motores.

    Objective To evaluate the clinical outcomes of selective anterior cervical corpectomy combined with segmental disectomy and fusion for treating three-level cervical myelopathy. Methods Thirtee patients of multilevel cervical myelopathy with 3 consecutive segments were treated with anterior cervical corpectomy combined with segmental disectomy and fusion. Study parameters included JOA score and grading the Odom criteria. The sagittal segmental alignment of fusion levels was measured using the Cobb method before and after surgery. Graft fusion rate was observed during final follow up. Results The patients were followed up for 12 to 39 months. The JOA score of 13 patients was higher three months after surgery than that before[(14. 6± 1.0) points vs. (11.1 ± 1.0) points] (P<0. 01). Surgical results of Odom criteria were excellent in 8 cases, good in 3 cases, fair in 2 cases. Graft fusion rate was 100%. Radiograph analysis indicated that the Cobb angle of mean segmental lordosis was 3.7 degrees before, 10.7 degrees one week later and 10.4 degrees during the final follow up. Conclusion Selective anterior cervical corpectomy combined with segmental disectomy and fusion results in high fusion rates with sufficient decompression in the treatment of three-level cervical myelopathy.%目的 分析颈前路选择性椎体次全切除十单间隙减压植骨融合术治疗三节段脊髓型颈椎病的临床疗效.方法 13例脊髓型颈椎病患者行颈前路选择性椎体次全切除十单间隙减压、自体髂骨植骨、钢板内固定术.分析术前及随访时的日本骨科协会(JOA)评分,记录术后Odom分级.测量术前、术后1周及末次随访时颈椎侧位X线片,观察术后颈椎植骨融合率、颈椎曲度(Cobb角)维持、症状及功能改善率.结果 13例患者随访12~39个月,术后3个月JOA评分为(14.6±1.0)分,明显高于术前的(11.1±1.0)分(P<0.01).术后Odom分级:优8例,良3例,一般2例,植骨融合率100%.

    Full Text Available Background:   After cervical discectomy, autogenetic bone is packed into the cage to increase the rate of union between adjacent vertebral bodies, but donor site–related complications can still occur. In this study we evaluate the use   of hydroxyapatite granules as a substitute for autograft for interbody fusion.     Methods:   From November 2008 to November 2011, 236 patients participated in this study. Peek cages were packed with autologous bone grafts taken from the iliac crest in 112 patients and hydroxyapatite (HA granules in 124 patients.   Patients were followed for 12 months. The patients’ neurological signs, results, and complications were fully recorded   throughout the procedure. Radiological imaging was done to assess the fusion rate and settling ratio.     Results:   Formation of bony bridges at the third month was higher in the autograft group versus the granule group. However, there was no difference between both groups at the 12-month follow-up assessment. No difference (     P > 0.05   was found regarding improvement in neurological deficit as well as radicular pain and recovery rate between the two groups. Conclusions:   Interbody fusion cage containing HA granules proved to be an effective treatment for cervical spondylotic radiculopathy and/or myelopathy. Clinical and neurological outcome, radiographic measurement and fusion rate   in cage containing HA are similar and competitive with autograft packed cages.

    Takayuki Hirai

    Full Text Available BACKGROUND: Cervical compressive myelopathy, e.g. due to spondylosis or ossification of the posterior longitudinal ligament is a common cause of spinal cord dysfunction. Although human pathological studies have reported neuronal loss and demyelination in the chronically compressed spinal cord, little is known about the mechanisms involved. In particular, the neuroinflammatory processes that are thought to underlie the condition are poorly understood. The present study assessed the localized prevalence of activated M1 and M2 microglia/macrophages in twy/twy mice that develop spontaneous cervical spinal cord compression, as a model of human disease. METHODS: Inflammatory cells and cytokines were assessed in compressed lesions of the spinal cords in 12-, 18- and 24-weeks old twy/twy mice by immunohistochemical, immunoblot and flow cytometric analysis. Computed tomography and standard histology confirmed a progressive spinal cord compression through the spontaneously development of an impinging calcified mass. RESULTS: The prevalence of CD11b-positive cells, in the compressed spinal cord increased over time with a concurrent decrease in neurons. The CD11b-positive cell population was initially formed of arginase-1- and CD206-positive M2 microglia/macrophages, which later shifted towards iNOS- and CD16/32-positive M1 microglia/macrophages. There was a transient increase in levels of T helper 2 (Th2 cytokines at 18 weeks, whereas levels of Th1 cytokines as well as brain-derived neurotrophic factor (BDNF, nerve growth factor (NGF and macrophage antigen (Mac-2 progressively increased. CONCLUSIONS: Spinal cord compression was associated with a temporal M2 microglia/macrophage response, which may act as a possible repair or neuroprotective mechanism. However, the persistence of the neural insult also associated with persistent expression of Th1 cytokines and increased prevalence of activated M1 microglia/macrophages, which may lead to neuronal loss and

    2012-01-01

    Cervical spondylosis is a broad term which describes the age related chronic disc degeneration, which can also affect the cervical vertebrae, the facet and other joints and their associated soft tissue supports. Evidence of spondylitic change is frequently found in many asymptomatic adults. Radiculopathy is a result of intervertebral foramina narrowing. Narrowing of the spinal canal can result in spinal cord compression, ultimately resulting in cervical spondylosis myelopathy. This review article examines the current literature in relation to the cervical spondylosis and describes the three clinical syndromes of axial neck pain, cervical radiculopathy and cervical myelopathy.

  20. Electromyographic study in radiation myelopathy

    International Nuclear Information System (INIS)

    The evoked electromyography method and the routine needle electrode methods were applied to four patients suffering from radiation myelopathy. The recovery curve and the repetitively evoked EMG of spinal activity were obtained from calf muscles giving electrical shocks to the tibial nerve in the popliteal fossa. The same experiments were carried out on thirty-seven irradiated patients suffering from malignant tumors as on normal subjects with the following results. In radiation myelopathies, the recovery curve showed a rapid enhancement exceeding 100% in its maximum value. Facilitation of the recovery curve was found to be markedly increased. The repetitive evoked EMG showed a smaller decrease of depression of the H-reflex. In some irradiated patients except radiation myelopathies also, the same facilitation and the decrease of depression were found. Routine needle electrode examinations showed such abnormal findings as High Amplitude Voltage, Fasciculation Voltage, signifing a neuronal degeneration in the anterior horn of the spinal cord in radiation myelopathies. The author concluded that abnormal EMG test findings are some of the important objective findings in radiation myelopathies available for diagnosis. (auth.)

  2. The morphometric analysis of the intervertebral foramen and the spinal nerve root in the cervical spine

    International Nuclear Information System (INIS)

    The purpose of this study was to clarify the onset of cervical myelopathy and cervical spondylotic radiculopathy as well as what influence the anatomy of the cervical spine and cervical nerves have on their onset and occurrence of various types of disease state. We conducted imaging and morphological measurements on specimens of cervical spine of Japanese people, focusing attention on the running of intervertebral foramen and dorsal nerve rootlets of the cervical spine. The subjects were cervical spine specimens from 12 cadavers (7 males and 5 females, age at the time of death ranged from 48 to 93 years with a mean of 71 years) obtained at Showa University School of Dentistry in 2005 and 2006. Specimens were prepared by removing the atlas through the 1st thoracic vertebra from the cadavers, then resecting the soft tissue such as muscles to expose the cervical spine in whole circumference. The removed cervical spine specimens, from 1st to 7th cervical spines, were imaged by volume scan of radiographic helical CT at 0.6 mm spatial resolution, and their images were stored as Digital Imaging and Communications in Medicine (DICOM) data. Image measurement on the vertebral body, vertebral foramen, and intervertebral foramen was conducted based on DICOM data. Furthermore, macroscopic observation and measurement were conducted on the dorsal nerve rootlets of cervical spine specimens. The image measurement of cervical spine specimens showed that the intervertebral foramen at C5/6 was the narrowest, followed by C3/4, C4/5, C6/7, and C2/3, respecting. With regard to angles in the frontal section and horizontal section of the groove for the spinal nerve, there was no significant difference in the angle between the right and the left. In the frontal section, the angle was about 63deg at C3, about 57deg at C4, about 52deg at C5, and about 55deg at C6, showing a significantly acute angle at C5, while in the horizontal section, it was about 54deg at C3, about 59deg at C4, about 63

    Background This retrospective study aimed to investigate the difference of the intra-dural reserving space for spinal cord in magnetic resonance imaging (MRI) between patients with and without developmental cervical stenosis and its clinical significance.Methods A total of 264 patients with cervical spondylotic myelopathy who had decompression surgeries were recruited.The average follow-up was 29 months.Based on their lateral radiographs,they were divided into stenosis group and non-stenosis group.On the magnetic resonance images,the ratio of the sagittal diameter of the dural sac to that of the vertebral body was measured and calculated as MRI Pavlov ratio at the mid-vertebral level on T2-weighted sagittal images from C3 to C7.The ratio of the transverse area of the spinal cord to that of the dural sac was measured and calculated as occupation ratio on T2-weighted axial images at the same levels.The MRI Pavlov ratio and occupation ratio were compared between the two groups.The stenosis group was further divided into space-reserving and non-space-reserving subgroups based on the occupation ratios; then clinical parameters were compared between the two subgroups to determine the clinical significance of the reserving space.Results The MRI Pavlov ratio of the stenosis group was significantly smaller than that of the non-stenosis group at C3-C7 (P <0.01),while the occupation ratio was significantly larger only at C7 (P <0.05).For the space-reserving subgroup,the postoperative recovery rate was lower (P <0.05).The postoperative recovery rate was (23±6)% in anterior approach,larger than (-23±15)% in posterior approach (P <0.05).Conclusions Developmental cervical stenosis is associated with a smaller sagittal diameter of the dural sac,but does not lead to a significant decrease in intra-dural space available for the cord.For patients with normal intra-dural space,the recovery after anterior decompression surgery was better than posterior approach.

  5. Radiation myelopathy with spinal cord swelling occurring three years after irradiation. A case report

    International Nuclear Information System (INIS)

    A 64-year-old woman developed progressive deterioration of sensations, gait, and bladder-bowel functions. The patient had suffered from malignant lymphoma in the neck, and underwent irradiation three years before admission. On admission, she exhibited cervical radiculomyelopathy including spastic tetraplegia, intrinsic muscle atrophy, sensory disturbance in the lower body, and sphincter disturbance. MRI showed diffuse high intensity in the cervical cord on T2-weighted image with Gd-enhancement on T1-weighted image. On serial MRI, swelling of the cervical cord progressed from 36 to 39 months after irradiation. Delayed swelling of the spinal cord can be associated with radiation myelopathy. (author)

    We report a case with compression myelopathy due to proliferative changes around the C2 pars defects without instability. A 69-year-old man presented with progressive clumsy hands and spastic gait. Plain radiographs showed bilateral spondylolysis (pars defects) at C2 and fusion between C2 and C3 spinous processes. Dynamic views revealed mobility through the pars defects, but there was no apparent instability. Computed tomography showed proliferative changes at the pars defects, which protruded into spinal canal. On magnetic resonance imaging, the spinal cord was compressed and intramedullary high signal change was found. A diagnosis of compression myelopathy due to proliferative changes around the C2 pars defects was made. We performed posterior decompression. Postoperatively, symptoms have been alleviated and images revealed sufficient decompression and no apparent instability. In patients with the cervical spondylolysis, myelopathy caused by instability or slippage have been periodically reported. The present case involving C2 spondylolysis is extremely rare.

    We conducted a prospective randomized study comparing stand-alone cage and bone autograft and plate implants in anterior cervical discectomy and fusion (www.clinicaltrials.gov, NCT01011569). Our interim analysis showed autologous bone graft with plating was superior to a stand-alone cage for segmental lordosis. During this analysis, we noted a difference in canal encroachment by the fusion mass between the two fusion groups. A narrow cervical spinal canal is an important factor in the development of cervical spondylotic myelopathy, therefore this unexpected potential risk of spinal cord compression necessitated another interim analysis to investigate whether there was a difference in canal encroachment by the fusion mass between the two groups. Patients had a minimum 1year of follow-up. The Neck Disability Index, neck and arm pain Visual Analog Scales and lateral radiographs, including bone fusion patterns, were evaluated. Twenty-seven (16 males, 11 females, mean age 54.8years) and 31 (24 males, seven females, mean age 54.5years) patients were in the cage and plate group, respectively. Both groups improved after surgery. Fusion began at 2.6months and 1.3months and finished at 6.7months and 4.0months in 24 (88.9%) and 28 (90.3%) patients in the cage and plate group, respectively. Encroachment into the spinal canal by the fusion mass was significantly different between the fusion types, occuring in 21 (77.8%) patients in the cage group versus six (19.4%) in the plate group (p=0.003). There was a high incidence of spinal canal encroachment by the fusion mass in the stand-alone cage group, possibly limiting use in narrow spinal canals. PMID:27234609

Materials and methods: The MRI images of 82 patients with less than 1 month of symptoms and signs of cervical radiculopathy were evaluated independently by two neuroradiologists who were unaware of clinical findings. MRI analysis was repeated after disclosure of clinical information. Interobserver agreement was calculated using kappa statistics. Results: The kappa score for evaluation of herniated discs and of spondylotic foramen stenosis was 0.59 and 0.63, respectively. A kappa score of 0.67 was found for the presence of root compression. After disclosure of clinical information kappa scores increased slightly: from 0.59 to 0.62 for the detection of herniated discs, from 0.63 to 0.66 for spondylotic foramen stenosis, and from 0.67 to 0.76 for root compression. Conclusion: Interobserver reliability of MRI evaluation in patients with cervical radiculopathy was substantial for root compression, with or without clinical information. Agreement on the cause of the compression, i.e., herniated disc or spondylotic foraminal stenosis, was lower.

    This study examined effect of a new intervertebral cervical disc prosthesis in relieving the neurological symptoms and signs, improving the patients' ability to perform daily activities, reducing pain, and maintaining the stability and segmental motion. From December 2003 to October 2004, 12 patients, who had received 14 replacements of cervical artificial discs, were followed-up for 2 to 8 months (with a mean of 5.2 months). Of them 5 had cervical spondylotic myelopathy and 7 had cervical disc herniation. The patients included 7 males and 5 females, with their age ranging from 35 to 62 y and a mean of 50.3 y. Single-level replacements were performed in 10 cases and 2 cases received two-level replacement. Operation time of the single-level surgery averaged 130±50 min and the time of two-level surgery was 165±53 min on average (from skin incision to skin suturing).Neurological or vascular complications during or after surgery was not observed. Japanese Orthopedic Association scores (JOA scores) increased from 8.6 to 15.8 on average. There was no prothesis subsidence or excursion. Replaced segments were stable and the range of motion was partially restored, being 4.68° (3.6°-6.1°) in flexion and extension position and 3.51° (2.5°-4.6°) 3.42° (2.6°-4.3°) in left and right bending position. No obvious loss of physiological curvature was noted. CT or MRI follow-up showed that excursion was less than 1.5 mm) in 2 of 14 levels and between 1.5 mm and 3 mm) in 1 of 14 levels. No ossification in the replaced levels was observed. It is concluded that satisfactory short-term results were achieved in the 12 cases of artificial disc replacements. Different from anterior cervical discectomy and fusion, the replacement could achieve quick functional recovery and did not lead to the movement limitation of cervical vertebrae. At least a 5-years follow-up was needed to assess the long-term effect of the prosthesis on its neighboring segments.

  16. Two children with chronic progressive radiation myelopathy

    International Nuclear Information System (INIS)

    We report two patients who developed chronic progressive radiation myelopathy (CPRM). Patient 1 was a 16-year-old boy with group IV rhabdomyosarcoma of cervical soft tissue. He underwent partial excision of the tumor and received systemic and intrathecal chemotherapy and 44 Gy of local radiotherapy (C4 through Th3). These therapies were followed by high-dose chemotherapy including thio-TEPA and busulfan with autologous bone marrow rescue. One year after the completion of the therapies, he developed CPRM. Patient 2 was a 15-year-old girl with acute lymphoblastic leukemia on the 3rd complete remission. She received 18 Gy of irradiation to whole brain during the 1st remission and another 18 Gy to whole brain and 9 Gy to spinal cord after her 1st CNS relapse. After successful reinduction therapy for the 2nd relapse in CNS and bone marrow, she underwent an allogeneic bone marrow transplantation (BMT). The preconditioning regimen consisted of 12 Gy total body irradiation, thio-TEPA and cyclophosphamide. Seven months after BMT, she developed CPRM at C0-C1 level, which was included in the area of whole-brain irradiation. In both patients, MR images showed a swelling of the cervical cord and ring-like images by gadolinium enhancement. Their neurological disability transiently responded to the administration of corticosteroid, but they developed progressive quadriplegia. Although it is reported that a dose of 45-50 Gy may be safe, these cases suggest that administration of high-dose chemotherapy combined with intrathecal chemotherapy and radiotherapy to the cord might increase the rink of developing CPRM.

    Full Text Available Multilevel cervical degenerative disc disease is well known in the cervical spine pathology, with radicular syndromes or cervical myelopathy. One or two level cervical herniated disc is common in adult and multilevel cervical degenerative disc herniation is common in the elderly, with spinal stenosis, and have the same cause: the gradual degeneration of the disc. We report the case of a patient with two level cervical disc herniation (C4 – C5 and C5 – C6 treated by anterior cervical microdiscectomy both levels and fusion at C5 – C6; after five years the patient returned with left C7 radiculopathy and MRI provided the image of a left C6 – C7 disc herniation, he underwent an anterior microsurgical discectomy with rapid relief of symptoms. Three-level cervical herniated disc are rare in adults, and the anterior microdiscectomy with or without fusion solve this pathology.

    OBJECTIVE Esophageal perforation is a rare but well-known complication of anterior cervical spine surgery. The authors performed a systematic review of the literature to evaluate symptomatology, direct causes, repair methods, and associated complications of esophageal injury. METHODS A PubMed search that adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines included relevant clinical studies and case reports (articles written in the English language that included humans as subjects) that reported patients who underwent anterior spinal surgery and sustained some form of esophageal perforation. Available data on clinical presentation, the surgical procedure performed, outcome measures, and other individual variables were abstracted from 1980 through 2015. RESULTS The PubMed search yielded 65 articles with 153 patients (mean age 44.7 years; range 14-85 years) who underwent anterior spinal surgery and sustained esophageal perforation, either during surgery or in a delayed fashion. The most common indications for initial anterior cervical spine surgery in these cases were vertebral fracture/dislocation (n = 77), spondylotic myelopathy (n = 15), and nucleus pulposus herniation (n = 10). The most commonly involved spinal levels were C5-6 (n = 51) and C6-7 (n = 39). The most common presenting symptoms included dysphagia (n =63), fever (n = 24), neck swelling (n = 23), and wound leakage (n = 18). The etiology of esophageal perforation included hardware failure (n = 31), hardware erosion (n = 23), and intraoperative injury (n = 14). The imaging modalities used to identify the esophageal perforations included modified contrast dye swallow studies, CT, endoscopy, plain radiography, and MRI. Esophageal repair was most commonly achieved using a modified muscle flap, as well as with primary closure. Outcomes measured in the literature were often defined by the time to oral intake following esophageal repair. Complications included

    Objective To discuss the risk factors of neurologic deterioration secondary to cervical spinal surgery . Methods 3703 patients with cervical degenerative disease treated surgically from September 2002 to September 2007 were reviewed. 12 patients suffered with neurologic deterioration within one week after operation. Age, course of disease, extent of disease, JOA score, preoperative companied disease and cerebrospinal leak were recorded. The saggital diameter of spinal canal, Povlov ratio and dynamic spinal stenosis parameter were measured on X-ray. And the dynamic spinal stenosis were measured using a modified Rao method in which both the distance from infer-posterior edge of upper vertebral body to the super-anterior edge of the lower laminar (UV-LL) and distance from super-posterior edge of lower vertebral body to the infer-anterior edge of the upper laminar (LV-UL) were measured. And the percentage of compression of spinal cord at the narrowest level was measured on middle saggital MRI section. Result There were 9 male and 3 female were included in these patients suffered from postoperative neurologic deterioration. The average age was 51 years and the average duration of symptoms was 71 months. The average JOA score declined from 10 preoperatively to 5 postoperatively and improved to 9 at the final follow up. The preoperative diameter of spinal canal was 11.8mm and the preoperative average Pavlov ratio was 0.65. The average distance of LV-UL was 11.2mm before operation and 12.7 after operation, while the distance of UV-LL was 15.1mm before operation and 13.6 after operation. Conclusion The risk factors of acute postoperative neurologic deterioration include Patients with preoperative hypertension, diabetes mellitus, cervical stenosis, cervical dynamic stenosis and more than 3 levels to acute postoperative neurologic deterioration.%目的 分析12例颈椎病术后神经功能恶化患者的危险因素并探讨其预防措施.方法 回顾性分析2002年9

    Conclusion: ACDF has been demonstrated to be an effective surgical procedure in treating degenerative spine disease in patients with radiculopathy and/or myelopathy. However, in a population with isolated radiculopathy and radiological imaging confirming an anterolateral disc or osteophyte complex, the MIPKF can provide similar results without the associated risks that accompany an anterior cervical spine fusion.

    OBJECTIVE Respiratory abnormalities are well documented in acute spinal cord injury; however, the literature available for respiratory dysfunction in chronic compressive myelopathy (CCM) is limited. Respiratory dysfunction in CCM is often subtle and subclinical. The authors studied the pattern of respiratory dysfunction in patients with chronic cord compression by using spirometry, and the clinical and surgical implications of this dysfunction. In this study they also attempted to address the postoperative respiratory function in these patients. METHODS A prospective study was done in 30 patients in whom cervical CCM due to either cervical spondylosis or ossification of the posterior longitudinal ligament (OPLL) was diagnosed. Thirty age-matched healthy volunteers were recruited as controls. None of the patients included in the study had any symptoms or signs of respiratory dysfunction. After clinical and radiological diagnosis, all patients underwent pulmonary function tests (PFTs) performed using a standardized Spirometry Kit Micro before and after surgery. The data were analyzed using Statistical Software SPSS version 13.0. Comparison between the 2 groups was done using the Student t-test. The Pearson correlation coefficient was used for PFT results and Nurick classification scores. A p value Cervical spondylotic myelopathy (prolapsed intervertebral disc) was the predominant cause of compression (n = 21, 70%) followed by OPLL (n = 9, 30%). The average patient age was 45.06 years. Degenerative cervical spine disease has a relatively younger onset in the Indian population. The majority of the patients (n = 28, 93.3%) had compression at or above the C-5 level. Ten patients (33.3%) underwent an anterior approach and discectomy, 11 patients (36.7%) underwent decompressive laminectomy, and the remaining 9 underwent either corpectomy with fusion or laminoplasty. The mean preoperative forced vital capacity (FVC) (65%) of the patients was significantly lower than that of

    The MRI examinations of seven patients with acute transverse myelopathy (ATM) were analysed. The patients were examined 2-5 times during the course of their disease with short and long TR/TE spin-echo sequences in the sagittal projection. A previous history of autoimmune disorder and/or signs of infection at the onset of ATM were present in all cases. Cerebrospinal fluid analysis showed local synthesis of immunoglobulin in the nervours system in three cases and signs of infectious myelitis in one. During the acute phase four patients had local enlargement of the cord and all had increased signal on long TR/TE sequences. The outcome was grave in the majority of patients and there seemed to be a correlation between the degree of cord enlargement, persistence of increased signal intensity and limited recovery. Atrophy and remaining high signal intensity were noted on late MRI patients with poor outcome. In one patient with probable anterior spinal artery occlusion, cavitation of the cord was seen. (orig.)

  11. MRI of the cranio-cervical region in rheumatoid arthritis

    International Nuclear Information System (INIS)

    16 patients suffering from rheumatoid arthritis and suspected compressive cervical myelopathy were studied with a 0.5 T superconducting magnetic resonance imaging (MRI) scanner. MRI findings were compared with those of plain radiography and myelography. Subluxation was detected equally well by MRI and radiography. MRI was able to detect the presence, level and origin of cord compression. MRI was superior in diagnosing the extent of cord compression. Cord distortion detected by MRI correlated better with clinical evidence of myelopathy than did the radiographically established extent of the subluxation. MRI correctly diagnosed the level and cause of cord compression in six patients who were subsequently operated upon because of progressive neurological signs. These findings suggest that MRI has potential in the diagnosis and management of patients with rheumatoid arthritis suspected of compressive cervical myelopathy. 20 refs.; 4 figs.; 1 table

  12. Imaging features of copper deficiency myelopathy: a study of 25 cases

    International Nuclear Information System (INIS)

    Acquired copper deficiency presents with a spastic gait and sensory ataxia. Spinal cord magnetic resonance imaging (MRI) in patients with copper deficiency myelopathy may show increased T2 signal, most commonly in the dorsal midline cervical and thoracic cord. These imaging findings may be reversible with normalization of serum copper. The clinical and imaging picture is very similar to the subacute combined degeneration seen in patients with vitamin B12 deficiency. Neuroradiologists should consider this possibility when a long segment of symmetric dorsal spinal cord T2-hyperintensity is identified. (orig.)

    We describe three patients with misdiagnosed unstable fractures of the cervical spine, who were treated conservatively and developed kyphotic deformity, myelopathy, and radiculopathy. All three patients were then managed with closed reductions by crown halo traction, followed by instrumented fusions. Their neurologic function was regained without permanent disability in any patient. Unstable fractures of the cervical spine will progress to catastrophic neurologic injuries without surgical fixation. Posttraumatic kyphosis and the delayed reduction of partially healed fracture dislocations by preoperative traction are not well characterized in the subaxial cervical spine. The complete evaluation of any subaxial cervical spine fracture requires CT scanning to assess for bony fractures, and MRI to assess for ligamentous injury. This allows for assessment of the degree of instability and appropriate management. In patients with delayed posttraumatic cervical kyphosis, preoperative closed reduction provided adequate realignment, facilitating subsequent operative stabilization. PMID:26321304

    To date, several studies were conducted to find which procedure is superior to the others for the treatment of cervical myelopathy. The goal of surgical treatment should be to decompress the nerves, restore the alignment of the vertebrae, and stabilize the spine. Consequently, the treatment of cervical degenerative disease can be divided into decompression of the nerves alone, fixation of the cervical spine alone, or a combination of both. Posterior approaches have historically been considere...

    1996-11-01

    In analysis of the cervical and cervicobrachial syndrome with or without signs of compression of the nerve root or spinal cord, functional assessment of the cervical spine is of great importance. Comparisons between actively performed and passively induced motion can be verified by using standardized computer-assisted assessment allowing precise documentation of the range of motion and coupled motion. The age-related normal values should be considered. The neurological assessment includes not only the cranial nerves and upper extremities but also lower extremities to avoid overlooking the signs of cervical myelopathy. In patients with compression of nerve roots or the spinal cord neurophysiology might be helpful in identifying or verifying compression. In patients with suspected myelopathy sensory evoked potentials will allow assessment of the function of the ascending spinal pathways and motor evoked potentials, assessment of the function of the descending cortical spinal pathways.

    An autopsy case of meningeal spreading of glioblastoma multiforme (GBM) probably originating in the cervical cord was reported. In contrast to autopsy findings, main symptoms were similar to subacute meningitis, and any signs of myelopathy could not be detected during the clinical course. The patient was a 22-year-old man who was hospitalized because of a 2-week history of progressive headache following cough and slight fever. Vomiting and somnolence, developing 5 days before admission, were improved the day after a lumbar puncture performed at another hospital. On admission, meningeal signs, mild right abducens palsy, and depressed deep tendon reflexes were detected. There was no muscle weakness, sensory loss, or Babinski sign. Lumbar puncture yielded CSF with an opening pressure of 280 mmH2O, 21 mononuclear cells/mm3, a protein level of 645 mg/dl, and a glucose level of 7 mg/dl. Cytology for malignancy and multiple cultures were negative. Brain CT scan showed mild hydrocephalus and swelling of the brainstem and cerebellum. Intravenous administration of antimicrobial drugs was started and ventriculoperitoneal shunt surgery was performed. During the third hospital week, however, meningeal signs progressed and somnolence reappeared, followed by progressive multiple cranial neuropathy and polyradiculopathy characterized by flaccid tetraparesis, muscle atrophy, and sensory impairment without a level. Babinski sign could not be detected. MRI revealed an intramedullary lesion in the lower cervical cord, swelling of the brainstem, cerebellum, spinal cord and nerve roots, and a diffuse or nodular thickning of leptomeninges. Repeated CSF cytology disclosed atypical cells. Examinations for extraneural malignancies were negative. During the 9th hospital week, flaccid tetraplegia progressed and stupor developed, and the patient died 2 weeks later. The pathological study was limited to the brain. The brain showed a diffuse opalescent thickening of the leptomeninges, especially

    after surgery. Methods Between January 2008 and August 2010, 51 patients underwent single segmental PRESTIGE LP replacement, and the clinical data were retrospectively analyzed. During the surgery, the patient was supinely placed and the lordosis of the cervical spine was mantained with a pillow placed beneath the neck. Of them, 28 were male and 23 were female, aged 30-64 years (mean, 45 years); 32 were diagnosed as having cervical spondylotic myelopathy, 7 having radiculopathy, and 12 having myelopathy and radiculopathy. The disease duration was 3-48 months (mean, 15 months). CDR was performed at Co in 5 cases, at C5.6 in 42 cases, and at C6,7 in 4 cases. The Cobb angles of the cervical alignment, targeted functional spinal unit (FSU), and targeted disc were measured by sagittal X-ray film of the cervical spine in neutral position before and after surgery, as well as the intraoperative C-arm fluroscopy of the cervical spine. Linear correlation and regression were performed to analyze the relation between cervical Cobb angle difference at intraoperation and improvement of the Cobb angles at 3 months after operation. Results The cervical Cobb angles at intraoperation and 3 months after operation were larger than those at preoperation (P < 0.05). The difference of the Cobb angle between intra- and pre-operation was (6.72 ± 9.13)° on cervical alignment, (2.10 ± 5.12)° on targeted FSU, and (3.33 ± 3.75)° on targeted disc. At 3 months after operation, the Cobb angle improvement of the cervical alignment, targeted FSU, and targeted disc was (6.30 ± 7.28), (3.99 ± 5.37), and (4.29 ± 5.36)°, respectively. There was no significant difference in the Cobb angle improvement between the targeted FSU and the targeted disc (t=-0.391, P=0.698), and between the targeted disc and the cervical alignment (t=-1.917, P=0.061), but significant difference was found between the targeted FSU and the cervical alignment (t=-2.623, P=0.012).

    The sagittal and cross diameters of the cervical spinal cord were measured in 53 patients with cervical nerve root compression and with no evidence of spinal cord involvement, as well as in 45 patients with spastic tetraparesis and no localised space occupying lesion, and 29 patients with myelographically proven cervical myelography. The true diameters were calculated by the known magnification factor (1:1,4). Patients with spastic tetraparesis showed diameters in normal ranges, as well as widened or diminished sizes of the cord. Some of the patients with cervical myelopathy showed diminished diameters in the caudal parts. This may be a hint for a poor outcome after decompression operation. (orig.)

    Scintiscanning of the cervical cerebrospinal fluid space at maximum ante- and retroflexion in 24 patients revealed the method to be recommended for use in the case of cervical myelopathy when the polymorphous early symptoms appear and before myelography as well as for follow-up examination. The detection of posture-induced constriction of the lumen provides additional information and increases the sensitivity considerably because, particularly during retroflexion, minor inflammatory reactions lead to scintigraphically detectable reduction in the liquor space.

It can be accompanied by motor, sensory, or reflex deficits and is most prevalent in persons 50 to 54 years of age. Cervical radiculopathy most often stems from degenerative disease in the cervical spine. The most common examination findings are painful neck movements and muscle spasm. Diminished deep tendon reflexes, particularly of the triceps, are the most common neurologic finding. The Spurling test, shoulder abduction test, and upper limb tension test can be used to confirm the diagnosis. Imaging is not required unless there is a history of trauma, persistent symptoms, or red flags for malignancy, myelopathy, or abscess. Electrodiagnostic testing is not needed if the diagnosis is clear, but has clinical utility when peripheral neuropathy of the upper extremity is a likely alternate diagnosis. Patients should be reassured that most cases will resolve regardless of the type of treatment. Nonoperative treatment includes physical therapy involving strengthening, stretching, and potentially traction, as well as nonsteroidal anti-inflammatory drugs, muscle relaxants, and massage. Epidural steroid injections may be helpful but have higher risks of serious complications. In patients with red flag symptoms or persistent symptoms after four to six weeks of treatment, magnetic resonance imaging can identify pathology amenable to epidural steroid injections or surgery.

    Cervical spondylosis is a common and disabling condition. It is generally felt that the initial management should be nonoperative, and these modalities include physiotherapy, analgesia and selective nerve root injections. Surgery should be reserved for moderate to severe myelopathy patients who have failed a period of conservative treatment and patients whose symptoms are not adequately controlled by nonoperative means. A review of the literature supporting various modalities of conservative management is presented, and it is concluded that although effective, nonoperative treatment is labour intensive, requiring regular review and careful selection of medications and physical therapy on a case by case basis.

    Full Text Available We report a rare patient of a simultaneous extradural and intradural compression of the cervical spinal cord due to co-existent intervertebral disc herniation and an intradural schwannoma at the same level. The intradural lesion was missed resulting in recurrence of myelopathy after a surprisingly complete functional recovery following anterior cervical discectomy. Retrospectively, it was noted that the initial cord swelling noticed was tumor being masked by the compression produced by the herniated disc. A contrast magnetic resonance imaging scan is important in differentiating intradural tumors of the spinal cord. A high index of suspicion is often successful in unmasking both the pathologies.

    Ossification of the posterior longitudinal ligament (OPLL) is a common spinal disorder that presents with or without cervical myelopathy. Furthermore, there is evidence suggesting that OPLL often coexists with cervical disc hernia (CDH), and that the latter is the more important compression factor. To raise the awareness of CDH in OPLL for spinal surgeons, we performed a retrospective study on 142 patients with radiologically proven OPLL who had received surgery between January 2004 and Janua...

    2013-09-01

    The term 'acute myelopathies'--referred to a spinal cord dysfunction--represent a heterogeneous group of disorders with distinct etiologies, clinical and radiologic features, and prognoses. The objective of this review is to discuss the non-traumatic acute myelopathies. Acute myelopathy can be due to several causes as infective agents or inflammatory processes, such as in acute myelitis, compressive lesions, vascular lesions, etc. The clinical presentation is often dramatic with tetraparesis or paraparesis, sensory disturbances and bladder and/or bowel dysfunction. History and physical examination are used to localize the lesion to the root or specific level of the cord, which can guide imaging. Different syndromes are recognized: complete transverse lesion, central grey matter syndrome, anterior horn syndrome, anterior spinal artery syndrome, etc). The first priority is to rule out a compressive lesion. If a myelopathy is suspected, a gadolinium-enhanced MRI of the spinal cord should be obtained as soon as possible. If there is no structural lesion such as epidural blood or a spinal mass, then the presence or absence of spinal cord inflammation should be documented with a lumbar puncture. The absence of pleocytosis would lead to consideration of non inflammatory causes of myelopathy such as arteriovenous malformations, fibrocartilaginous embolism, or possibly early inflammatory myelopathy. In the presence of an inflammatory process (defined by gadolinium enhancement, cerebrospinal fluid pleocytosis, or elevated cerebrospinal fluid immunoglobulin index), one should determine whether there is an inflammatory or an infectious cause. Different virus, bacterias, parasites and fungi have to be considered as autoimmune and inflammatory diseases that involve the central nervous system. PMID:23897140

    2002-01-01

    Full Text Available Developmental stenosis without any significant spondylotic changes frequently occurs at C3 vertebra or below, and typically extends to C6-C7. However, high cervical focal canal stenosis is unusual. A case of cervical canal segmental stenosis at C2-3 level in addition to a developmental stenosis of the lumbar region, in a 45 year old male, has been presented in this article. The dynamics of the spinal canal in relation to the likely pathology of such conditions are reviewed. We speculate that focal segmental stenosis in the high cervical region may be due to a possible premature fusion of the neurocentral synchondrosis of the cartilage, or due to an abnormal rotary biomechanics which can result in facetal hypertrophy.

    Teixeira, Stephanie; Moser, Franklin; Kotton, Ryan H

    2016-02-01

    Surfer's myelopathy is a rare non-traumatic cause of myelopathy found in novice surfers. We present a case of a 23-year-old female who developed acute and rapidly progressive bilateral lower extremity paraplegia, paresthesia, and anesthesia, accompanied by lower back discomfort and bowel and bladder dysfunction after surfing for the first time. She had a past history of auto-resolved lower extremity weakness that could be related to anatomy variation of spinal cord vascular supply. This individual variation could have increased the risk for ischemic myelopathy after prolonged prone position with back hyperextension on the surf board. We discuss radiological findings of acute spinal cord infarct and longitudinal extensive transverse myelitis (LETM) as possible differentials in this case. The diagnosis of surfer's myelopathy relies on a first time surfing history since the clinical and radiological presentations can be similar to other entities in some cases. Thus, we highlight the importance of a full clinical report and efficient communication between referring clinicians and radiologists for a precise and early diagnosis. PMID:26394636

    Cervical radiculopathy is a common clinical scenario. Patients with radiculopathy typically present with neck pain, arm pain, or both. We review the epidemiology of cervical radiculopathy and discuss the diagnosis of this condition. This includes an overview of the pertinent findings on the patient history and physical examination. We also discuss relevant clinical syndromes that must be considered in the differential diagnosis including peripheral nerve entrapment syndromes and shoulder pathology. The natural history of cervical radiculopathy is reviewed and options for management are discussed. These options include conservative management, non-operative modalities such as physical therapy, steroid injections, and operative intervention. While the exact indications for surgical intervention have not yet been elucidated, we provide an overview of the available literature regarding indications and discuss the timing of intervention. The surgical outcomes of anterior cervical decompression and fusion (ACDF), cervical disc arthroplasty (CDA), and posterior cervical foraminotomy (PCF) are discussed. PMID:27250042

    Full Text Available Objective: To determine the clinical and functional results of short- and medium-term cervical arthroplasty with the Prestige LP® prosthesis for the treatment of compressive myelopathy, radiculopathy and axial pain with radiculopathty. Methods: This retrospective study, conducted from 2009 to 2012, included 18 patients. Only 16 were found for the second stage of research, conducted in 2011 and 2012. Pre- and postoperative assessments were carried out using the CSOQ (Cervical Spine Outcomes Questionnaire. Odom criteria were used only in the postoperative evaluation. Both were translated and adapted to the local culture. Results: There was no postoperative radiculopathy or other complications requiring prolonged hospitalization. In most patients, there was a significant improvement in axial pain and radiculopathy, and there was only one indication of conversion to fusion. Conclusions: In selected cases of cervical degenerative disc disease, herniated cervical disc and compressive myeolopathy, cervical arthroplasty proved to be an effective and safe treatment in the short and medium terms.

    2014-03-01

    Full Text Available Intradural disc herniation has been reported as a rare and particular type of intervertebral disc herniation. It occurs mostly in the lumbar spine, and rarely in the cervical or thoracic spine. Non-traumatic cervical intradural disc herniation is rare, with only 17 cases reported in English literature at the cervical region and can manifest itself by severe symptoms such as Brown-Sequard syndrome, transverse myelopathy and radiculopathy. We present a unique case of intradural cervical disc herniation only causing lower extremity monoplegia. To our knowledge, this is the first case described in the literature. The patient underwent microsurgical removal of the herniated disc via an anterior approach followed by interbody fixation using a cervical cage. J Clin Exp Invest 2014; 5 (1: 112-114

  16. Relationships between radiography of cervical vertebrae and histopathology of the cervical cord in wobbling 19 foals

    International Nuclear Information System (INIS)

    Nineteen wobbling foals (17 males and 2 females) showing lameness of hindlimbs at 6 to 21 months of age were investigated radiographically and histopathologically. Minimum sagittal diameter (MSD), minimum flexion diameter (MFD) and minimum dural sagittal diameter (MDD) were measured on plain radiograms or myelograms taken at neutral and flexed positions as indicators of narrowed vertebral canal. After necropsy, the cervical spines and the spinal cord were examined macroscopically and respectively the relationships between radiographic findings and the corresponding morphological lesions were evaluated. Radiographically, lower values than each minimum reference limits were recorded in 14 foals in MSD, 5 foals in MFD and 6 foals in MDD, respectively. According to the histopathologic examination, the disappearance of axons and myelin sheaths, vacuolated spongy degeneration and appearance of macrophages were recognized symmetrically in the white matter of the cervical cord. These lesions were centrally located at the spinal cord radiographically demonstrated as compressed sites in 12 out of 17 foals examined. Macroscopically, asymmetrical overgrowth of one side of the process, encroachment of articular processes into the intervertebral foramina and proliferation of bone around articular facets were observed in the articular processes of bone specimens in the caudal neck of 6 foals. In conclusion, the equine incoordination might mainly be caused by the cervical stenotic myelopathy resulting from cervical vertebral malformation, and therefore the cervical vertebral radiography, especiallymyelography, is quite very important and effective for the diagnosis of wobbling foals

    spondylotic myelopathy with developmental cervical stenosis and 13 cases of ossification of the posterior longitudinal ligament.Twenty one cases underwent modified open-door laminoplasty using anchor method,and the other 22 cases underwent laminoplasty with preservation of the unilateral muscular ligament complex.According to midsagittal T2-weighted MRI in the neutral position,several parameters indicating shift distance of the spinal cord and dural sac were measured at each level before operation and at 3 months after operation:shift of anterior margin of the spinal cord (SAMSC),shift of posterior margin of the spinal cord (SPMSC),shift of anterior margin of the dural sac (SAMDS) and shift of posterior margin of the dural sac (SPMDS).The line connecting the top of dens and posterior inferior angle of T1 was defined as E line and the length was E.The length of perpendicular line from each base point to E line was Px (x =1-6).The parameter (100×Px/E) was used to represent local curvature at each level,and the curvature index (CI)was used to represent the global curvature of the cervical spine.Then correlation analyses of the parameters above were performed.Results There was no significant change in SAMDS at different level after surgery,however SAMSC,SPMSC and SPMDS changed significantly and synchronously.At the level of C5 and C6,SPMSC was maximum,but not correlated to CI.Actually,SPMSC was correlated to the local curvature and highly correlated to SPMDS at the same level.Conclusion After cervical laminoplasty,posterior shifting of the spinal cord was highly correlated to posterior shifting of the dural sac at the same level,weakly correlated to local curvature and not correlated to the global curvature of the cervical spine.

    Multimodality evoked potentials (EPs) consisting of somatosensory EPs (SEPs), visual EPs (VEPs) and brainstem auditory EPs (BAEPs) were studied in 16 cases with HTLV-I associated myelopathy (HAM). Median nerve SEPs were normal in all cases. In posterior tibial nerve SEPs, the potential recorded at the 12th thoracic spinal process was normal in every case but cortical components were significantly prolonged in 10 cases, although five of these showed no sensory impairment. BAEPs were normal in ...

    Macrophages are frequently present within the periaxonal and intramyelinic vacuoles that are located primarily in the posterior and lateral funiculi of the thoracic spinal cord in HIV-associated vacuolar myelopathy. But the role of these macrophages in the formation of the vacuoles is unclear. One hypothesis is that cytokines, such as interleukin-1 (IL-1) and tumor necrosis factor (TNF)-alpha, are produced locally by macrophages and have toxic effects on myelin or oligodendrocytes. The resulting myelin damage eventually culminates in the removal of myelin by macrophages and vacuole formation. We studied thoracic spinal cord specimens taken at autopsy from HIV-positive (+) and HIV-negative individuals. The predominant mononuclear cells present in HIV+ spinal cords are macrophages. They are located primarily in the posterior and lateral funiculi regardless of the presence or absence of vacuolar myelopathy. Macrophages and microglia are more frequent in HIV+ than HIV-negative individuals and these cells frequently stain for class I and class II antigens, IL-1, and TNF-alpha. Activated macrophages positive for IL-1 and TNF-alpha are great increased in the posterior and lateral funiculi of HIV+ individuals with and without vacuolar myelopathy, suggesting they are present prior to the development of vacuoles. Cytokines, such as TNF-alpha, may be toxic for myelin or oligodendrocytes, leading to myelin damage and removal by macrophages and vacuole formation. PMID:8492917

    Fifty seven patients (42 males and 15 females) with non-compressive myelopathy were studied from 1997 to 1999. Acute transverse myelitis (ATM) was the commonest (31) followed by Vit B12 deficiency myelopathy (8), primary progressive multiple sclerosis (5), hereditary spastic paraplegia (3), tropical spastic paraplegia (2), subacute necrotising myelitis (1), radiation myelitis (1), syphilitic myelitis (1) and herpes zoster myelitis (1). 4 cases remained unclassified. In the ATM group, mean age was 30.35 years, antecedent event was observed in 41.9% case, 25 cases had symmetrical involvement and most of the cases had severe deficit at onset. CSF study carried out in 23 patients of ATM revealed rise in proteins (mean 147.95mg%, range 20-1200 mg/dL) and pleocytosis (mean 20.78/cumm, range 0-200 mm3). Oligoclonal band (OCB) was present in 28% of cases of ATM. The most common abnormality detected was a multisegment hyperintense lesion on T2W images, that occupied the central area on cross section. In 6 patients hyperintense signal was eccentric in location. MRI was normal in 4 cases of ATM. Thus ATM is the leading cause of non-compressive myelopathy. Clinical features combined with MRI findings are helpful in defining the cause of ATM. PMID:10625902

  9. Late progressive radiation myelopathies. A study of 27 cases

    International Nuclear Information System (INIS)

    Radiation myelopathies exist incontestably. 27 new cases are reported which are added to the more than 500 cases already analyzed in the world literature. However, if there is no doubt as to existence of these myelopathies, discussions persist concerning their nature: purely vascular, cytotoxic, probably mixed, perhaps maintained and prolonged by a superimposed immunologic phenomenon. Prevention is the sole method to be effective. It must be applied as much to the patient as to the technique of irradiation. With regard to the technical plan, several factors incontestably favor the appearance of radiation myelopathy: large medullary volumes irradiated, especially when they encompass the zones of vascular medullary junction; the overlap of fields involving the spinal cord; the reduction of fields too close to the spinal cord not allowing at least 1cm margin of relative security; the association of physical agents in the measure to which the global dosimetry is uncertain, i.e. in particular the use of high energy electrons for boost dosage, the intensity of which must be chosen with the greatest prudence; finally and most importantly, it seems desirable not to surpass at the level of the spinal cord, treating 5 times per week, a dose of 5000 rads with fractions of 200 rads, of 4500 rads with fractions of 250 rads and 4000 rads with fractions of 300 rads

  14. Cervical spine degenerative diseases: An evaluation of clinical and imaging features in surgical decisions

    International Nuclear Information System (INIS)

    In clinically severe cervical spondylosis, imaging plays a vital role in surgical decisions. A prime factor is acquired canal stenosis with cord compression. To validate this concept, the clinical and imaging features of 20 patients with spondylitic myelopathy and 24 with radiculopathy were retrospectively reviewed. All had computed tomographic myelography (CTM) as part of their clinical work-up. The patients' clinical severity was graded as mild, moderate and severe; the age, length of illness and a history of eventual surgery or otherwise were recorded. At the level of maximum compression the following parameters were obtained from the axial CTM images: surface area and ratio of the anteroposterior to the transverse diameter of the cord; subarachnoid space and vertebral canal areas. Data were statistically analysed. A significant association exists between surgery and increasing severity of symptoms (P=0.04), and advancing age (P=0.01). These associations hold true for myelopathy and radiculopathy. A strong association is present between surgery and the surface area of the cord (P=0.01), being applicable to myelopathy only. The other parameters show no association with surgical decisions. It is concluded that with myelopathy a narrow cord area at the level of maximum compression, and moderate-severe functional impairment are indicators for surgical intervention. (authors)

    Full Text Available BACKGROUND AND OBJECTIVES: Surgical treatment of cervical radiculopathy with or without myelopathy is a controversy issue, although anterior discectomy is the most common form of treatment. METHOD: We present the evaluation of the arthrodesis' rate and cervical alignment in 48 patients with cervical degenerative disease (CDD submitted to anterior cervical discectomy with interposition of polymethylmetacrylate (PMMA. Odom and Nürick scales were used to evaluation of functional status before and after surgery. Cervical spine X-rays were used to access arthrodesis and alignment, at least 2 years after the procedure. RESULTS: Excellent and good results (Odom I and II were obtained in 91% of the patients with radiculopathy and in 69% of those with myelopathy. Using the chi square test of independence (1% of significance, there was no association between excellent and good clinical results with the presence of arthrodesis verified in cervical X-rays. The presence of cervical alignment had association with good results, whereas the misalignment was associated with unfavorable outcomes. Two patients died: one cervical hematoma and other from graft migration with cord compression. CONCLUSIONS: Cervical alignment was more important than fusion to achieve good surgical results in CDD.TEMA E OBJETIVO: O tratamento cirúrgico da radiculopatia cervical com ou sem mielopatia é um tema controverso, embora a discectomia por via anterior seja uma das formas mais comuns de tratamento.

    Full Text Available Aim: The author reports early post-operative outcome and preliminary experience with an alternative form of treatment of cervical degenerative or spondylotic disease leading to spinal canal stenosis that involves fixation-arthrodesis of the affected spinal segment using one or two (double insurance transarticular screws for each joint. Materials and Methods: During the period of months from March 2013 to July 2013, six patients having cervical spondylotic cord compression were treated with transarticular method of screw fixation of the involved segments. The operation involved section of the spinous process at its base, opening up of the facet joint, denuding of articular cartilage, placement of intraarticular cavity bone graft chips and insertion of either a single or two transarticular screws at each level. The fixation was done in four levels in four patients and at two levels in two patients. Japanese Orthopedic Association score, visual analog scale (neck pain and Odom′s criteria were used to monitor the clinical status of the patients before and after the surgery and at follow-up. Results: Immediate post-operative and a relatively short-term post-operative outcome was remarkably gratifying. During the average period of follow-up of 6 months (range: 3-8 months; there was varying degree of recovery of symptoms. The procedure resulted in firm stabilization and fixation of the spinal segment and provided a ground for arthrodesis. No patient worsened after treatment. During the period of follow-up, all patients showed remarkable and progressive recovery in symptoms. Conclusions: Vertical instability and telescoping, listhesis or overriding of the facets on physical activity seems to be the defining phenomenon in pathogenesis of cervical spondylotic disease. The clinical outcome in our patients suggest that only fixation of the spinal segment can be a rationale form of treatment. Transarticular method of treatment is a simple, safe and

    Spinal dural arterio-venous fistula (DAVF) is rare and usually involves the thoracic segments. The classical presentation is a slowly progressive ataxia. Clinical presentation of intracranial DAVF depends on the site of the DAVF, as well as the vessels involved. Patients may present with pulsatile tinnitus, occipital bruit, headache, dementia, visual impairment as well as neurological deterioration distant from the DAVF as a result of venous hypertension and cortical haemorrhage. The authors present a rare case of progressive myelopathy secondary to an intracranial DAVF.

    Patients with end stage renal disease on hemodialysis may present with destructive spondyloarthropathy of the spine, most commonly in the subaxial cervical and lumbar spine, often with severe stenosis and instability. However, surgical management of these patients is challenging due to a high pseudarthrosis rate, poor bone quality, and medical frailty. We present a 49-year-old man on hemodialysis who presented with C4-C5 vertebral body destruction and a focal kyphotic deformity with myelopathy. The patient underwent a 360 degree decompression and reconstructive procedure that resulted in posterior instrumentation failure. Several salvage techniques were used in order to adequately stabilize the spine while preserving the patient's remaining cervical motion. PMID:27052255

    Introduction Cervical spondylotic myelo-radiculopathy is a form of spinal cord dysfunction syndrome and usually accompanies age related degeneration of the spine. Aim To determine the functional outcome of anterior cervical discectomy with fusion and plating in single level degenerative cervical disc prolapse. Materials and Methods A total of 20 patients diagnosed with degenerative single level cervical disc prolapse who presented to the Department of Orthopaedic Surgery, Justice KS Hegde Charitable Hospital, Mangalore from the period of November 2012 to May 2014 were enrolled in the study. Complete clinical and radiological evaluation of the patients was done. A trial of conservative management was tried in all these patients for a period of two months. They were taken up for surgery only when conservative management had failed. Scoring of neck function before the surgery was done as per the Modified Japanese Orthopaedic Association (MJOA) score. All patients underwent anterior cervical discectomy and fusion (ACDF) with tricortical iliac crest bone grafting. Fixation was performed with titanium locking cervical plates. All patients were reviewed at 6 weeks and 6 months postoperatively. Assessment of neck function was done as per the MJOA scoring during all the reviews. Radiographic assessment was also done during all the reviews. The complications noted were documented. The statistical analysis was done using percentages; the arithmetic mean was calculated using SPSS software (version 16.0). Results Amongst the 20 patients included in the study, 1 patient died postoperatively due to oesophageal rupture. of the remaining 19 patients reviewed and followed up, all of them had improvement of symptoms and were reported to be in the ‘mild category’ as per the MJOA score. One patient developed dysphonia, in the immediate postoperative period due to recurrent laryngeal nerve palsy which recovered in a period of three months postoperative. Conclusion Single level

    Subacute necrotizing myelopathy(SNM) is a rare non-tumorous disease of spinal cord characterized by subacute clinical course of progressive neurological deterioration. We report MR findings of a patient with pathologically proved SNM. 1 case of pathologically proved subacute necrotizing myelopathy. The patients was a 56-year-old man with progressive motor weakness and sensory loss of the lower extremities, and urinary and fecal incontinence for 11 months. Spine MRI revealed diffuse enlargement of the thoracic spinal cord from T2 to T7 level. Signal intensity of the expanded spinal cord was isointense relative to normal cord on T1-weighted image and hyperintense on proton-density and T2-weighted images. On contrast enhanced T1-weighted image, there was diffuse homogeneous enhancement in the expanded cord lesion. MR demonstration of stable persistence of spinal cord lesion or atrophy over months or years with clinical findings of gradual progressive neurologic deterioration may be helpful in the diagnosis of SNM.

    A 70-year-old woman was admitted complaining of gait disturbance and difficulty in urination. Neurological examination showed myelopathy and both serum and CSF anti ATLA antibodies were positive. A diagnosis of HTLV-associated myelopathy (HAM) was made and steroid therapy was initiated. Chest X-ray film on admission showed no abnormality, but three months later, diffuse fine nodular and reticular shadows appeared in both lung fields. The patients had no respiratory symptom. The results of pulmonary function tests were normal, aside from a mild obstructive defect as indicated by reduced V25. Arterial blood gas was also normal. Bronchoalveolar lavage studies showed increased total cell counts and an increased proportion of T-cells. The histological findings of the transbronchial lung biopsy specimen were bronchiolitis and alveolitis. Subsequently, within the next eight months the abnormal shadows on chest X-ray cleared gradually on maintenance dosage of prednisolone, 10 mg/day. Possible relationships between HAM and the pulmonary lesions were discussed. PMID:2625816

  5. Atlantoaxial subluxation. Radiography and magnetic resonance imaging correlated to myelopathy

    Yamashita, Y.; Takahashi, M.; Sakamoto, Y.; Kojima, R.

    Twenty-nine patients with atlantoaxial subluxation (18 with rheumatoid arthritis, 2 due to trauma, 4 with os odontoideum, and one each with polyarteritis nodosa, rheumatic fever, Klippel-Feil syndrome, achondroplasia, and cause unknown) were evaluated using a 0.22 tesla resistive MRI unit. Cord compression was classified into four grades according to the degree on magnetic resonance imaging. There were 7 patients with no thecal sac compression (grade 0), 10 with a minimal degree of subarachnoid space compression without cord compression (grade 1), 7 with mild cord compression (grade 2), and 5 with severe cord compression or cord atrophy (grade 3). Although the severity of myelopathy showed poor correlation with the atlantodental interval on conventional radiography, high correlation was observed between MR grading and the degree of myelopathy. The high signal intensity foci were observed in 7 or 12 patients with cord compression (grades 2 and 3) on T2 weighted images. Other frequently observed findings in rheumatoid arthritis included soft tissue masses of low to intermediate signal intensity in the paraodontoid space, erosions of the odontoid processes, and atlanto-axial impaction on T1 and T2 weighted images.

    Full Text Available Abstract Background laminectomy is a valuable surgical treatment for some patients with a cervical radiculomyelopathy due to cervical spinal stenosis. More recently attention has been given to motion of the spinal cord over spondylotic spurs as a cause of myelopathic changes. Immobilisation by fusion could have a positive effect on the recovery of myelopathic signs or changes. This has never been investigated in a prospective, randomised trial. Lamifuse is an acronyme for laminectomy and fusion. Methods/Design Lamifuse is a multicentre, randomised controlled trial comparing laminectomy with and without fusion in patients with a symptomatic cervical canal stenosis. The study population will be enrolled from patients that are 60 years or older with myelopathic signs and/or symptoms due to a cervical canal stenosis. A kyphotis shape of the cervical spine is an exclusion criterium. Each treatment arm needs 30 patients. Discussion This study will contribute to the discussion whether additional fusion after a cervical laminectomy results in a better clinical outcome. ISRCT number ISRCTN72800446

  10. Symptomatic ossification of the posterior longitudinal ligament of the cervical spine: pictorial essay

    International Nuclear Information System (INIS)

    Symptomatic ossification of the posterior longitudinal ligament (OPLL) of the cervical spine is a rare but well documented condition. It is the causative factor in up to 5% of cases presenting with cervical radiculopathy or myelopathy. Computed tomography is the modality of choice in showing the distinctive characteristics and extent of the disease. Magnetic resonance imaging (MRI) is sensitive in detecting cord compression and its attendant complications. Cervical OPLL commonly affects those of middle and advanced age, and the condition is noted to be particularly common in Japanese, although other racial groups are also affected. A 'mushroom' or 'hill' shape on axial CT typifies OPLL. A sharp radiolucent line separating the posterior vertebral margin from the superficial component of the ossified ligament is a characteristic feature. Copyright (1999) Blackwell Science Pty Ltd

    Although classically associated with patients of East Asian origin, ossification of the posterior longitudinal ligament (OPLL) may cause myelopathy in patients of any ethnic origin. Degeneration of the PLL is followed by endochondral ossification, resulting in spinal cord compression. Specific genetic polymorphisms and medical comorbidities have been implicated in the development of OPLL. Patients should be evaluated with a full history and neurologic examination, along with cervical radiographs. Advanced imaging with CT and MRI allows three-dimensional evaluation of OPLL. Minimally symptomatic patients can be treated nonsurgically, but patients with myelopathy or severe stenosis are best treated with surgical decompression. OPLL can be treated via an anterior (ie, corpectomy and fusion) or posterior (ie, laminectomy and fusion or laminoplasty) approach, or both. The optimal approach is dictated by the classification and extent of OPLL, cervical spine sagittal alignment, severity of stenosis, and history of previous surgery. Anterior surgery is associated with superior outcomes when OPLL occupies >50% to 60% of the canal, despite increased technical difficulty and higher complication rates. Posterior surgery is technically easier and allows decompression of the entire cervical spine, but patients may experience late deterioration because of disease progression. PMID:24966248

  13. New titanium spacer for cervical laminoplasty. Initial clinical experience. Technical note

    International Nuclear Information System (INIS)

    Many commercially available hydroxyapatite (HA) spacers for cervical laminoplasty have been introduced but have disadvantages such as lack of plasticity, easy cracking, and occasional difficulty in fixation by sutures. Here we present the short-term results of a newly designed titanium spacer (Laminoplasty Basket) in open-door cervical laminoplasty, and evaluated clinically and radiologically. The titanium box-shaped spacer with two arms for fixation was easily inserted and fixed into the laminoplasty space with 4-mm or 5-mm length screws after the posterior cervical arch was repositioned for the canal expansion. Twenty-one patients with cervical myelopathy due to spondylosis or ossification of the longitudinal ligament or developmental narrow canal observed for more than 6 months postoperatively were enrolled in this study. The neurological condition of these patients improved from 9.4 points on the Japanese Orthopaedic Association scale preoperatively to 13.5 points at 6 months after surgery. Postoperative radiological evaluation showed no laminar closure or implant failure and cervical spine curvature was maintained. These results seemed to have no significant difference compared with those using HA spacers. This titanium spacer is a potential substitute for conventional HA or other similar devices in cervical laminoplasty. (author)

    Two middle-aged women with malignancy of the aerodigestive tract were treated by megavoltage irradiation. Both subsequently developed transverse myelopathy. The diagnosis of radiation myelitis was rendered in one. The other was thought to have metastatic compression of the spinal cord; in this case, evidence was such that radiation myelopathy also was appropriate. The irradiation dose-time relationships in both patients were biologically low compared to published isoeffect curves available in the literature. The first patient had injury within the irradiated region and the main neurological damage was found there. In the second patient the entire spinal cord was necrotic, clearly placing the second case outside the radiation myelopathy syndrome. Gross and microscopic examinations of the tissues of these two patients show that the remote effects of malignancy upon the central nervous system can imitate the clinical picture of radiation myelitis.

    We retrospectively reviewed acute cervical cord injury after minor trauma in 10 patients with os odontoideum. Their clinical history, neurological symptoms, radiological investigations, follow-up period, American Spinal Injury Association impairment classification and motor score were reviewed. Before their traumatic injury, three patients were asymptomatic and seven reported myelopathic symptoms, including four patients with neck pain, two patients with unsteadiness and one patient with dizziness. Falls were the most common cause of injury (n=6), followed by minor motor vehicle accidents (n=3) and assault (n=1). MRI and dynamic cervical lateral radiographs showed that all patients had atlantoaxial instability and cord compression. Most patients had spinal cord thinning and hyperintensity on T2-weighted MRI. Spinal cord compression was posterior (n=5), or both anterior and posterior (n=5). All patients underwent posterior rigid screw fixation and fusion, including atlantoaxial fusion (n=8) and occipitocervical fusion (n=2). We conclude that patients with asymptomatic or myelopathic atlantoaxial instability secondary to os odontoideum are at risk for acute spinal cord injury after minor traumatic injury. Fixation and fusion should be undertaken as prophylactic treatment for patients at risk of developing myelopathy and to avoid the neurological deterioration associated with acute traumatic cervical cord injury.

    Study Design Case report. Objective Synovial cysts in the subaxial cervical spine are rare and are most commonly reported at the cervicothoracic junction. Only six cases of symptomatic C5-C6 synovial cysts have been reported in the literature; the condition is usually treated with decompressive laminectomy. We present a patient with a synovial cyst arising from the C5-C6 facet joint, associated with spondylolisthesis, and causing radiculomyelopathy. The patient was treated with a posterior excision of the cyst, decompressive laminectomy, and fusion. Methods A 67-year-old man had vertebral canal stenosis at C5-C6 secondary to a synovial cyst and spondylolisthesis with symptoms and signs of radiculopathy and myelopathy. Surgical management involved C5-C6 posterior decompressive laminectomy and excision of the cyst and C4-C6 instrumented fusion with lateral mass screws and rods. A literature review of symptomatic cervical synovial cysts is presented. Results The imaging studies identified grade I spondylolisthesis and a 3.3 × 4.3-mm extradural lentiform-like mass associated with focal compression of the spinal cord and exiting the C6 nerve root. After the surgery, the patient had an immediate full recovery and was asymptomatic by the 6-month examination. No operative complications were reported. The histologic report confirmed the presence of a synovial cyst. Conclusions C5-C6 is an unusual localization for symptomatic synovial cysts. Similar cases reported in the literature achieved excellent results after cyst excision and decompressive laminectomy. Because spondylolisthesis plus laminectomy are risk factors for segmental instability in the cervical spine, we report a case of a C5-C6 facet synovial cyst successfully treated with posterior laminectomy and C4-C6 fusion.

    Cervical-cord damage is a complication of a difficult delivery, and results in spinal shock with flaccidity progressing to spastic paralysis. Conventionally, outlook for such patients is extremely poor and most will recover only slightly from quadriplegia and autonomic dysfunction. Here, we report a case in which the extent of damage considerably contrasted with the outcome and recovery. A full-term baby girl born by difficult vaginal delivery displayed bilateral flaccid paralysis of the lower limbs with absent spontaneous movements, weakness of both upper limbs, hyporeflexia in all limbs and axial hypotonia. MRI of cervicothoracic spine exhibited raised signal intensity in the dorsal aspects of C7 to T1 signifying myelopathy. MRI at 4 months revealed a near-total transection of the cervical cord. However, at 6 months, the child could move all lower limbs independently with a marked increase in power. There was no spasticity, wasting or incontinence. Reflexes had also returned. PMID:23230249

    Vascular myelopathies of the spinal cord have not been described in Suidae, and are a rare finding in companion animals. An 8.5-yr female African warthog (Phacochoerus africanus) presented with an acute onset of tetraparesis. Based on neurologic findings, a cervical spinal cord lesion between C7-T2 was suspected. Magnetic resonance imaging revealed severe intramedullary hemorrhage with suspected abnormal vessels in the spinal cord at the level of the seventh cervical vertebrae. The acute onset of clinical signs and rapid deterioration of neurological status precluded surgical managements. A vascular anomaly was suspected on gross pathology and histology. Immunohistochemistry identified the lesion as a spontaneous intramedullary hematoma. Spontaneous intramedullary hematomyelia should be considered as a differential for acute onset of paresis in suid species. PMID:17319141

  2. Comparison of myelography, CT myelography and magnetic resonance imaging in cervical spondylosis and disk herniation

    International Nuclear Information System (INIS)

    Twenty-six patients with cervical radiculopathy and/or myelopathy caused by spondylosis or disk herniation were examined with myelography, CT myelography and MR. Fourteen of the patients were operated upon and 11 of them underwent postoperative MR and CT. The three radiologic methods provided comparable information about narrowing of the subarachnoid space and compression of the spinal cord. It was more difficult to distinguish bone from soft tissue with MR only, but the combination of MR and conventional radiography gave sufficient information for this differentiation. When radiologic nerve root sheath deformity was compared with clinical radiculopathy, myelography, CT myelography and MR had similar sensitivity and accuracy. Post-operative MR could reveal remaining indentation on the thecal sac and the cord but CT without contrast medium was useful as a complement to determine the aetiology of the indentation. Because MR has several practical advantages, it is well suited as the primary imaging modality, together with conventional radiography, for the preoperative radiologic evaluation of patients with cervical radiculopathy and/or myelopathy. Postoperative MR is useful in patients with persistent or new symptoms. (orig.)

  3. Magnetic resonance imaging of the cervical and thoracic spine and the spinal cord

    International Nuclear Information System (INIS)

    Magnetic resonance imaging (MR), using a 0.3 T resistive scanner with an iron core and a vertical magnetic field, was evaluated in patients with different diseases affecting the cervical and thoracic spine and the spinal cord. The results indicate that MR is well suited as the procedure of choice for emergency examination of patients with spinal cord symptoms, for examination of patients with suspected spinal multiple sclerosis and for pre-operative evaluation of patients with rheumatoid arthritis with neurological symptoms emanating from the cranio-cervical junction. In patients with cervical radiculapathy and/or myelopathy, caused by spondylosis or disk herniation, MR was found to be equivalent with myelography and CT myelography but MR has several practical advantages. MR at 0.3 T using a vertical magnetic field provided information comparable to that reported from examinations performed with superconducting MR scanners. In order to optimize the MR examinations of the spine, the signal characteristics of different coils available when using a vertical magnetic field were determined by phantom studies. Recommendations for optimal coil selection for different levels of the cervical and thoracic spine are given. In addition, the paramagnetic contrast medium gadolinium-DTPA was administered intravenously to patients with suspected spinal multiple sclerosis. Enhancement of clinically active lesions in the cervical spinal cord was observed. Serial MR examinations with gadolinium-DTPA showed that a decrease in enhancement could be correlated with decrease in clinical symptoms and signs. (author)

    Full Text Available Bacground/Aim. Diagnostic protocol for patients with degenerative diseases of the cervical spine demands, in parallel with neuroimaging methods, functional evaluation through neurophysiological methods (somatosensitive and motor evoked potentials and electromyoneurography aiming to evaluate possible subclinical affection of spinal medula resulting in neurological signs of long tract abnormalities. Considering diversities of clinical outcomes for these patients, complex diagnostic evaluation provides a prognosis of the disease progression. Methods. The study included 21 patients (48.24 ± 11.01 years of age with clinical presentation of cervical spondylarthropathy, without neuroradiological signs of myelopathy. For each patient, in addition to conventional neurophysiological tests (somatisensory evoked potentials - SSEP, motor evoked potentials - MEP, electromyoneurography - EMG, nerve conduction studies, we calculated central motor conduction time (CMCTF, as well the same parameter in relation to a different position of the head (maximal anteflexion and retroflexion, so-called dynamic tests. Results. Abnormalities of the peripheral motor neurone by conventional EMNeG was established in 2/3 of the patients, correponding to the findings of root condution time. Prolonged conventional CVMPF were found in 29% of the patients, comparing to 43% CVMPF abnormalities found with the dynamic tests. In addition, the SSEP findings were abnormal in 38% of the patients with degenerative diseases of the cervical spine. Conclusion. An extended neurophysiological protocol of testing corticospinal functions, including dynamic tests of central and periheral motor neurons are relevant for detection of subclinical forms of cervical spondylothic myelopathy, even at early stages. In addition to the conventional neurophysiological tests, we found usefull to include the dynamic motor tests and root conduction time measurement in diagnostic evaluation.

    2014-01-01

    Full Text Available Background: The selection, neurodiagnostic evaluation, and surgical management of patients with cervical ossification of the posterior longitudinal ligament (OPLL remain controversial. Whether for prophylaxis or treatment, the decision to perform anterior vs. posterior vs. circumferential cervical OPLL surgery is complex. MR and CT Documentation of OPLL: Together, MR and CT cervical studies best document the full extent of OPLL. While MR provides the optimal soft-tissue overview (e.g. hyperintense signals reflecting edema/myelomalacia in the cord, CT′s directly demonstrate the ossification of OPLL often "missed" by MR (e.g. documents the single or double layer signs of dural penetration. Patient Selection: Patients with mild myelopathy/cord compression rarely require surgery, while those with moderate/severe myelopathy/cord compression often warrant anterior, posterior, or circumferential approaches. Operative Approaches: Anterior corpectomies/fusions, warranted in patients with OPLL and kyphosis/loss of lordosis, also increase the risks of cerebrospinal fluid (CSF leaks (e.g. single/double layer sign, and vascular injuries (e.g. carotid, vertebral. Alternatively, with an adequate lordosis, posterior procedures (e.g. often with fusions, may provide adequate multilevel decompression while minimizing risk of anterior surgery. Occasionally, combined pathologies may warrant circumferential approaches. Anesthetic and Intraoperative Monitoring Protocols: The utility of awake nasotracheal fiberoptic intubation/awake positioning, intraoperative somatosensory/motor evoked potential, and electromyographic monitoring, and the requirement for total intravenous anesthesia (TIVA for OPLL surgery is also discussed. Conclusion: Anterior, posterior, or circumferential surgery may be warranted to treat patients with cervical OPLL, and must be based on careful patient selection, and both MR and CT documentation of the full extent of OPLL.

    Full Text Available Although anterior cervical instrumentation was initially used in cervical trauma, because of obvious benefits, indications for its use have been expanded over time to degenerative cases as well as tumor and infection of the cervical spine. Along with a threefold increase in incidence of cervical fusion surgery, implant designs have evolved over the last three decades. Observation of graft subsidence and phenomenon of stress shielding led to the development of the new generation dynamic anterior cervical plating systems. Anterior cervical plating does not conclusively improve clinical outcome of the patients, but certainly enhances the efficacy of autograft and allograft fusion and lessens the rate of pseudoarthrosis and kyphosis after multilevel discectomy and fusions. A review of biomechanics, surgical technique, indications, complications and results of various anterior cervical plating systems is presented here to enable clinicians to select the appropriate construct design.

  16. Clinical analysis of spinal cord injury with or without cervical ossification of the posterior longitudinal ligament, spondylosis, and canal stenosis in elderly head injury patients

    International Nuclear Information System (INIS)

    Patients with degenerative diseases of the cervical spine, such as ossification of the posterior longitudinal ligament, spondylosis, and canal stenosis, sometimes present with acute spinal cord injury caused by minor trauma. However, the relative risk of cervical cord injury with these diseases is unknown. The clinical and radiological features of 94 elderly patients with head injury, 57 men and 37 women aged from 65 to 98 years (mean 76.6 years), were retrospectively analyzed to assess the association of spinal cord injury with degenerative cervical diseases. Degenerative cervical diseases were present in 25 patients, and spinal cord injury was more common in the patients with degenerative diseases (11/25 patients) than in the patients without such diseases (3/69 patients; relative risk=10.2). The incidence of degenerative cervical diseases seems to be increasing in Japan because life expectancy has increased and the elderly are a rapidly growing part of the population. A fall while walking or cycling is a common mechanism of head injury and/or cervical cord injury in the elderly. To decrease the occurrence of cervical myelopathy, prevention by increasing social awareness and avoiding traffic accidents and falls is important. (author)

  17. Biomechanical evaluation of DTRAX® posterior cervical cage stabilization with and without lateral mass fixation

    Introduction Lateral mass screw (LMS) fixation with plates or rods is the current standard procedure for posterior cervical fusion. Recently, implants placed between the facet joints have become available as an alternative to LMS or transfacet screws for patients with cervical spondylotic radiculopathy. The purpose of this study was to evaluate the biomechanical stability of the DTRAX® cervical cage for single- and two-level fusion and compare this to the stability achieved with LMS fixation with rods in a two-level construct. Methods Six cadaveric cervical spine (C3–C7) specimens were tested in flexion–extension, lateral bending, and axial rotation to ±1.5 Nm moment without preload (0 N) in the following conditions: 1) intact (C3–C7), 2) LMS and rods at C4–C5 and C5–C6, 3) removal of all rods (LMS retained) and placement of bilateral posterior cages at C5–C6, 4) bilateral posterior cages at C4–C5 and C5–C6 (without LMS and rods), and 5) C4–C5 and C5–C6 bilateral posterior cages at C4–C5 and C5–C6 with rods reinserted. Results Bilateral posterior cervical cages significantly reduced range of motion in all tested directions in both single- and multilevel constructs (P<0.05). Similar stability was achieved with bilateral posterior cages and LMS in a two-level construct: 0.6°±0.3° vs 1.2°±0.4° in flexion–extension (P=0.001), (5.0°±2.6° vs 3.1°±1.3°) in lateral bending (P=0.053), (1.3°±1.0° vs 2.2°±0.9°) in axial rotation (P=0.091) for posterior cages and LMS, respectively. Posterior cages, when placed as an adjunct to LMS, further reduced range of motion in a multilevel construct (P<0.05). Conclusion Bilateral posterior cages provide similar cervical segmental stability compared with a LMS and rod construct and may be an alternative surgical option for select patients. Furthermore, supplementation of a lateral mass construct with posterior cages increases cervical spine stability in single- and multilevel conditions. PMID

    Ossification of ligamentum flavum (OLF) is a well-known pathology causing myelopathy, although it is a rare disease. The most commonly affected population is from the Far East and mainly Japanese. However, few reports and studies have shown the prevalence of the disease all over the world. We report the case of a 33-year-old man presenting with signs of progressive myelopathy. Magnetic resonance imaging (MRI) showed Th2-Th11 OLF with severe narrowing and intramedullary hypersignal at the level Th2-Th3. This is the first Lebanese case reported in the literature. A decompressive laminectomy with flavectomy was done. This case adds to the previous reported cases on the occurrence of the disease in different populations. PMID:27057241

    Ossification of the posterior longitudinal ligament is a common cause of the cervical myelopathy due to compression of the spinal cord. Patients with ossification of the posterior longitudinal ligament usually require the decompression surgery, and there is a need to better understand the optimal surgical extent with which sufficient decompression without excessive posterior shifting can be achieved. However, few quantitative studies have clarified this optimal extent for decompression of cervical ossification of the posterior longitudinal ligament. We used finite element modeling of the cervical spine and spinal cord to investigate the effect of posterior decompression extent for continuous-type cervical ossification of the posterior longitudinal ligament on changes in stress, strain, and posterior shifting that occur with three different surgical methods (laminectomy, laminoplasty, and hemilaminectomy). As posterior decompression extended, stress and strain in the spinal cord decreased and posterior shifting of the cord increased. The location of the decompression extent also influenced shifting. Laminectomy and laminoplasty were very similar in terms of decompression results, and both were superior to hemilaminectomy in all parameters tested. Decompression to the extents of C3-C6 and C3-C7 of laminectomy and laminoplasty could be considered sufficient with respect to decompression itself. Our findings provide fundamental information regarding the treatment of cervical ossification of the posterior longitudinal ligament and can be applied to patient-specific surgical planning.

    Full Text Available Background and purpose: Cervical radiculopathy is one of the most common diseases that must be diagnosed early and properly to prevent its serious side effects. For this purpose different paraclinical methods such as MRI, X-ray, EMG, NCV and SSEP are used. Each of these methods has its limitations and some of them are expensive or invassive. The aim of this study was to compare the electrodiagnostic and radiologic methods in diagnosis of cervical radiculopathy.Materials and Methods: In this study 36 patients (22 Female, l4 Male with complaint of cervical pain radiated to upper limbs were evaluated. The evaluation included EMG, NCV, MRI, X-ray and SSEP. Exclusion criteria were fracture dislocation and infection of bone joints or soft tissues .MRI and X-ray were performed in MRI centers of Isfahan, Sepahan and Alzahra hospital in Isfahan city. MRI was graded on severity of 1 to 3. EMG, NCV and SSEP were performed in electrodiagnostic center of Alzahra hospital by one professional technician. Results were compared with text books and analyzed by SPSS software.Results: Sensitivity of SSEP was 28.6% and specifity was 100%. Partial agreement between SSEP and MRI existed in moderate and severe cervical involvements (P = 0.005. Frequencies of abnormalities were: EMG 50%, NCV 5.6%, X-ray 33.3% and MRI 77.8%.Conclusion: This study shows that SSEP has lower value than EMG in diagnosis of cervical radiculopathy. Also in a patient with cervical radiculopathy, cervical MRI and EMG of upper limbs are necessary. SSEP abnormalities in the presence of moderate and severe MRI changes such as myelopathy, are more valuable. Therefore, SSEP in cervical radiculopathy is recommended before surgery.

    Anterior procedures in the cervical spine are feasible in cases having anterior aetiologies such as anterior neural compression and/or severe kyphosis. Halo vests or anterior plates are used concurrently for cases with long segmental fixation. Halo vests are bothersome and anterior plate fixation is not adequately durable. We developed a new anterior pedicle screw (APS) and plate fixation procedure that can be used with fluoroscope-assisted pedicle axis view imaging. Six patients (3 men and 3 women; mean age, 54 years) with anterior multisegmental aetiology were included in this study. Their original diagnoses comprised cervical myelopathy and/or radiculopathy (n = 4), posterior longitudinal ligament ossification (n = 1) and post-traumatic kyphosis (n = 1). All patients underwent anterior decompression and strut grafting with APS and plate fixation. Mean operative time was 192 min and average blood loss was 73 ml. Patients were permitted to ambulate the next day with a cervical collar. Local sagittal alignment was characterised by 3.5 degrees of kyphosis preoperatively, which improved to 6.8 degrees of lordosis postoperatively and 5.2 degrees of lordosis at final follow-up. Postoperative improvement and early bony union were observed in all cases. There was no serious complication except for two cases of dysphagia. Postoperative imaging demonstrated screw exposure in one screw, but no pedicle perforation. APS and plate fixation is useful in selected cases of multisegmental anterior reconstruction of cervical spine. However, the adequate familiarity and experience with both cervical pedicle screw fixation and the imaging technique used for visualising the pedicle during surgery are crucial for this procedure.

    The surgical treatment of cervical kyphotic deformity remains challenging. As a surgical method that is safer and avoids major complications, the authors present a procedure of single-stage anterior and posterior fusion to correct cervical kyphosis using anterior interbody fusion cages without plating, as illustrated by three consecutive cases. Case 1 was a 78-year-old woman who presented with a dropped head caused by degeneration of her cervical spine. Case 2 was a 54-year-old woman with athetoid cerebral palsy. She presented with cervical myelopathy and cervical kyphosis. Case 3 was a 71-year-old woman with cervical kyphotic deformity following a laminectomy. All three patients underwent anterior release and interbody fusion with cages and posterior fusion with cervical lateral mass screw (LMS) fixation. Postoperative radiographs showed that correction of kyphosis was 39° in case 1, 43° in case 2, and 39° in case 3. In all three cases, improvement of symptoms was established without major perioperative complications, solid fusion was achieved, and no loss of correction was observed at a minimum follow-up of 61 months. We also report that preoperative total spine sagittal malalignment was improved after corrective surgery for cervical kyphosis and was maintained at the latest follow-up in all three cases. The combination of anterior fusion cages and LMS is considered a safe and effective procedure in cases of severe cervical kyphotic deformity. Preoperative total spine sagittal malalignment improved, accompanied by correction of cervical kyphosis, and was maintained at last follow-up in all three cases. PMID:26119893

    Peethambaran, Anilkumar

    2016-01-01

    Schwannomas are the most common intradural extramedullary tumors of the spine. They usually occupy a posterolateral or lateral position in relation to the cord. The ventral midline is a very rare location for the origin of a spinal schwannoma. A giant one in such a location causes technical difficulties in excision. Here, we present a giant cervical spinal schwannoma, located ventral to the cord, in a 38-year-old lady who presented with features of myelopathy and bladder involvement. Magnetic resonance imaging was suggestive of an intradural extramedullary lesion extending from cervico-medullary junction to the third dorsal vertebral level with severe cord compression. The same was excised totally via a posterior approach after midline suboccipital craniectomy and C2–C6 laminoplasty. Postoperatively, she made a good recovery and was ambulant without support. Postoperative magnetic resonance imaging showed complete excision of the tumor. Histopathology was suggestive of schwannoma. PMID:26949471

    The authors present the case of progressive thoracic myelopathy caused by the extensive ossification of the arachnoid membrane and associated intramedullary syrinx. Based on their findings and results of the literature search, they describe a pathological basis for this rare condition, discuss its incidence and symptomatology, and suggest a simple classification for various types of the arachnoid ossification. They also discuss the magnetic resonance imaging features of arachnoid ossification and associated spinal cord changes. The particular value of plain computerized tomography, which is highly sensitive in revealing intraspinal calcifications and ossifications, in the diagnostic evaluation of patients with a clinical picture of progressive myelopathy is emphasized.

    In recent years, many authors have reported that an extruded lumbar intervertebral disc was absorbed through phagocytosis and dehydration. However, absorption of an extruded cervical intervertebral disc has rarely been reported. We have investigated the follow-up MRI of all 24 patients with cervical disc herniation seen between 1991 and 1995. Of these, 8 patients with radiculopathy and 7 with myelopathy had been treated nonoperatively, and a further 9 patients with severe myelopathy had undergone expansive laminoplasty. In follow-up MRI, a reduction in the size of the extruded disc was seen in 5 of the 15 nonoperative patients and in 8 of the 9 operative patients. The 9 operative patients showed a mean recovery rate of 68.4{+-}15.2% (range from 44 to 90%) according to their JOA score. In the nonoperative group, recovery of symptoms was seen in all 5 patients with reduction, and in only 4 of 10 patients with nonreduction. The initial MRI of the 5 patients with reduction was taken between 2 and 7 weeks (mean 4 weeks) after onset, and between 1 month and 14 years (mean 13 months, not including the one at 14 years) after onset in the 10 patients with nonreduction. The initial MRI of the 9 operative patients was taken between 1 month and 6 years (mean 14 months after onset). The pathomechanism for disc reduction was concluded to have been the same as for lumbar disc herniation in the nonoperative patients. However, the pathomechanism in the operative patients was inconclusive and was likely to be different from that in the nonoperative patients. (author).

    The purpose of this study was to examine the relationship between the location of the cervical cord compression and the increased signal intensity within the cervical cord on T2-weighted imaging (T2WI) in patients with cervical myelopathy and myelomalacia. We reviewed 1,615 MRI reports from January 2011 to May 2013 from a single institution. Of the 1,615 reports reviewed, 168 patients were diagnosed with increased signal intensity within the cervical spine on T2WI. After applying the exclusion criteria 82 patients were included in the study. The MRIs of these 82 patients were then reviewed and the location of the increased signal intensity on T2WI in relation to the location of the pressure on the spinal cord was recorded. In more than 50 % of the cases the lesions with increased signal intensity on T2WI either were located distal to the pressure on the spinal cord or started at the level of the pressure and extended to an area distal to the pressure. In 26 out of the 92 lesions with increased signal intensity on T2WI, the lesion started proximal to the pressure on the spinal cord and extended distal to it. In only 3 out of the 92 lesions, the lesion with increased signal intensity on T2WI was solely located proximal to the pressure on the spinal cord. In 5 other cases the lesion with increased signal intensity on T2WI started proximal to the level of pressure on the spinal cord and extended into the level of pressure on the spinal cord (p < 0.001; Table 1). Cervical myelomalacia may appear proximal, distal or at the level of the compressed cord. It rarely appears solely proximal to the pressure area on the cord. (orig.)

    We describe a case of a 19-year-old young man with oligoarthritis type of juvenile idiopathic arthritis, who presented with several month duration of lower neck pain and progressive muscular weakness of all four limbs. X-rays of the cervical spine demonstrated spontaneous apophyseal joint fusion from the occipital condyle to C6 and from C7 to Th2 with marked instability between C6 and C7. Surgical intervention began with anterolateral approach to the cervical spine performing decompression, insertion of cage and anterior vertebral plate and screws, followed by posterior approach and fixation. Care was taken to restore sagittal balance. The condition was successfully operatively managed with multisegmental, both column fixation and fusion, resulting in pain cessation and resolution of myelopathy. Postoperatively, minor swallowing difficulties were noted, which ceased after three days. Patient was able to move around in a wheelchair on the sixth postoperative day. Stiff neck collar was advised for three months postoperatively with neck pain slowly decreasing in the course of first postoperative month. On the follow-up visit six months after the surgery patient exhibited no signs of spastic tetraparesis, X-rays of the cervical spine revealed solid bony fusion at single mobile segment C6-C7. He was able to gaze horizontally while sitting in a wheelchair. Signs of myelopathy with stiff neck and single movable segment raised concerns about intubation, but were successfully managed using awake fiber-optic intubation. Avoidance of tracheostomy enabled us to perform an anterolateral approach without increasing the risk of wound infection. Regarding surgical procedure, the same principles are obeyed as in management of fracture in ankylosing spondylitis or Mb. Forestrier. PMID:27458558

    Nearly all children with MPS IVA develop skeletal deformities affecting the spine. At the atlanto-axial spine, odontoid hypoplasia occurs. GAG deposition around the dens, leads to peri-odontoid infiltration. Transverse/alar ligament incompetence causes instability. Atlanto-axial instability is associated with cord compression and myelopathy, leading to major morbidity and mortality. Intervention is often required. Does the presence of widened bullet shaped vertebra in platyspondily encroach on the spinal canal and cause spinal stenosis in MPS IVA? So far, there have been no standardised morphometric measurements of the paediatric MPS IVA cervical spine to evaluate whether there is pre-existing spinal stenosis predisposing to compressive myelopathy or whether this is purely an acquired process secondary to instability and compression. This study provides the first radiological quantitative analysis of the cervical spine and spinal cord in a series of affected children. MRI morphometry indicates that the MPS IVA spine is narrower at C1-2 level giving an inverted funnel shape. There is no evidence of a reduction in the Torg ratio (canal-body ratio) in the cervical spine. The spinal canal does not exceed 11 mm at any level, significantly smaller than normal historical cohorts (14 mm). The sagittal diameter and axial surface area of both spinal canal and cord are reduced. C1-2 level cord compression was evident in the canal-cord ratio but the Torg ratio was not predictive of cord compression. In MPS IVA the reduction in the space available for the cord (SAC) is multifactorial rather than due to congenital spinal stenosis. PMID:23404316

    Imaging techniques provide excellent anatomical images of the cervical spine. The choice to use one technique or another will depend on the clinical scenario and on the treatment options. Plain-film X-rays continue to be fundamental, because they make it possible to evaluate the alignment and bone changes; they are also useful for follow-up after treatment. The better contrast resolution provided by magnetic resonance imaging makes it possible to evaluate the soft tissues, including the intervertebral discs, ligaments, bone marrow, and spinal cord. The role of computed tomography in the study of degenerative disease has changed in recent years owing to its great spatial resolution and its capacity to depict osseous components. In this article, we will review the anatomy and biomechanical characteristics of the cervical spine, and then we provide a more detailed discussion of the degenerative diseases that can affect the cervical spine and their clinical management.

    Abstract Background: We report 8 years of follow-up after decompression to treat cervical myelopathy in a patient with Coffin–Lowry syndrome (CLS). CLS is a rare X-linked semidominant syndrome associated with growth and psychomotor retardation, general hypotonia, and skeletal abnormalities. In this patient, the spinal cord was compressed by calcium pyrophosphate crystal deposition in the cervical yellow ligament (YL). To date, only 1 report has described clinical features after surgery for calcified cervical YL in CLS. Methods: A 15-year-old male with tetraplegia secondary to compression of the cervical spinal cord induced by a hypoplastic posterior arch of C1 and calcification of the YL from C2 to C7 was treated surgically with laminectomy from C1 to C7. The patient's history, clinical examination, imaging findings, and treatment are reported. The patient was incapable of speech because of mental retardation, so he could not describe his symptoms. Gait disturbance worsened over the 2 months before admission to our hospital. At admission, the patient could not move his extremities, and tendon reflexes of the upper and lower extremities were significantly increased. Computed tomography of the cervical spine showed YL calcification from C2 to C7. Magnetic resonance imaging showed consecutive compression of the cervical spinal cord. We diagnosed quadriplegia secondary to cervical cord damage and performed emergency surgery. Results: During C1–C7 laminectomy, YL calcification in C2–C7 was observed. The calcification was confirmed as calcium pyrophosphate by crystal analysis. Quadriplegia gradually resolved, and almost disappeared by 2 weeks after the operation. Cervical hyperlordosis was observed in radiographs starting from 1 month after the operation, but it has not progressed and is not associated with any symptoms. Conclusions: The efficacy of decompression continued, and no postoperative complications have occurred during at least 8 years of follow-up. PMID

  4. Mielopatia por deficiência de vitamina B12 apresentando-se como mielite transversa Myelopathy due to vitamin B12 deficiency presenting as transverse myelitis

    Full Text Available As manifestações neurológicas associadas à deficiência de vitamina B12 incluem polineuropatia, mielopatia, demência e neuropatia óptica. O diagnóstico laboratorial é feito através da dosagem sérica de cianocobalamina ou homocisteína e da excreção urinária de ácido metilmalônico. No estudo anatomopatológico observa-se na microscopia a destruição da mielina e de axônios vistos na substância branca. A região mais comumente afetada é o cordão posterior cervical e/ou torácico. O acometimento da coluna lateral é raro, ocorrendo em casos graves e avançados. O tratamento consiste na reposição de vitamina B12 e a resposta depende da gravidade do quadro e do tempo transcorrido entre o inicio dos sintomas e inicio do tratamento. Relatamos o caso de um paciente que apresentou, como manifestação de deficiência de vitamina B12, mielite transversa. O estudo morfológico da medula demonstrou comprometimento dos tractos cortico-espinhais lateral e anterior, da coluna dorsal e ainda do tracto espino-talâmico.Vitamin B12 deficiency may induce neuropathy, myelopathy, dementia and optic neuropathy. The diagnosis is established by vitamin B12, homocysteine and methylmalonic acid measurements. Myelin and axon destruction in the white matter of the spinal cord are observed. The posterior column of the cervical and thoracic level is the most common involved area. The involvement of the anterior column is restricted to advanced and relatively severe cases. Treatment is based on vitamin B12 injections, and the prognosis depends on the stage of vitamin deficiency and deterioration at treatment onset. We report a case with transverse myelitis due to vitamin B12 deficiency. This picture is relatively uncommon, however, we believe patients with transverse myelitis should have vitamin B12 studies as part of the diagnosis work up.

    Full Text Available Cervical necrotizing fasciitis is an unusual encounter in the general surgical practice, but is a life-threatening condition requiring early recognition and adequate surgical treatment. We present the case of a 65 year old male patient referred to our department from a General Hospital. Large excisions of both superficial and deep cervical fascia were required together with necrotic skin on a very large surface. Rapid recovery with early sterilization allowed adequate skin grafting with good results. We advocate for aggressive debridment with excision in viable healthy tissue, with no concern for the future reconstruction followe by early grafting of the skin defect.

    2009-01-01

    Full Text Available Background: Operative procedures like simple discectomy, with or without fusion and with or without instrumentation, for single level cervical disc herniation causing neck pain or neurological compromise have been described and are largely successful. However, there is a debate on definitive criteria to perform fusion (with or without instrumentation for single level cervical disc herniation. Hence, we conducted a questionnaire based study to elicit the opinions of practicing neurosurgeons. Materials and Methods: About 148 neurosurgeons with atleast 12 years of operative experience on single level cervical disc herniation, utilizing the anterior approach, were enrolled in our study. All participating neurosurgeons were asked to complete a practice based questionnaire. The responses of 120 neurosurgeons were analysed. Results: The mean age of enrolled surgeons was 51 yrs (range 45-73 with mean surgical experience of 16.9 yrs (range 12-40 yrs on single level cervical disc herniation. Out of 120 surgeons 10(8% had 15-25 years experience and always preferred fusion with or without instrumentation and six (five per cent with 17-27 yrs experience had never used fusion techniques. However, 104 (87% surgeons with 12-40 yrs experience had their own criteria based on their experiences for performing fusion with graft and instrumentation (FGI, while. 85 (75% preferred auto graft with cage. Conclusions: Most of surgeons performed FGI before the age of 40, but for others, patient criteria such as job (heavier job, physical examination (especially myelopathy and imaging findings (mild degenerative changes on X-ray and signal change in the spinal cord on MRI were considered significant for performing FGI.

    Human T-cell lymphotropic virus type 1 (HTLV-1) is associated with adult T-cell leukemia/lymphoma (ATL) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Only a limited percentage of infected individuals develop disease in response to the virus while the majority remain asymptomatic, and HAM/TSP is the most common clinical manifestation of the virus. HAM/TSP is an inflammatory disease of the central nervous system (CNS); however, the mechanism by which HTLV-1 induces HAM/TSP is not yet clear. CD4(+) T lymphocytes are the main reservoirs of HTLV-1 in vivo and perform an important role in the immunological response to this retrovirus. This virus-host interaction may provoke changes in the immunological response, such as the enhanced production of inflammatory cytokines and the spontaneous proliferation of T CD4(+) lymphocytes, which are implicated in the pathogenesis of HAM/TSP.

  11. Wall-eyed bilateral internuclear ophthalmoplegia (webino syndrome and myelopathy in pyoderma gangrenosum

    Directory of Open Access Journals (Sweden)

    Marco Aurélio Lana

    1990-12-01

    Full Text Available A 35-year-old female with pyoderma gangrenosum developed paraparesis with a sensory level at L1. Three months later she complained of diplopia and was found to have bilateral internuclear ophthalmoplegia with exotropia and no ocular convergence. The term Webino syndrome has been coined to design this set of neuro-opthalmologic findings. Although it was initially attributed to lesions affecting the medial longitudinal fasciculus and the medial rectus subnuclei of the oculomotor complex in the midbrain the exact location of the lesion is still disputed. In the present case both myelopathy and Webino syndrome were probably due to vascular occlusive disease resulting from central nervous system vasculitis occurring in concomitance to pyoderma gangrenosum.

  12. Solitary Osteochondroma of the Thoracic Spine with Compressive Myelopathy; A Rare Presentation

    International Nuclear Information System (INIS)

    A 19-year-old man presented with a 5-year history of back pain radiating to the lower extremities and paresthesis of the toes during the last year. Plain X-ray revealed a large cauliflower shaped exophytic mass at the level of T8, T9 and T10 vertebrae. Computed tomography (CT) and magnetic resonance imaging (MRI) showed an abnormal bony mass arising from the posterior arch of T9 with protrusion to the spinal canal and marked cord compression. The cortex and medulla of the lesion had continuity with those of the T9 vertebra. Surgical en bloc resection was performed and the patient’s symptoms resolved. The histopathologic diagnosis was osteochondroma. In patients with symptoms of myelopathy, in addition to more common etiologies, one should also be aware of rare entities such as osteochondroma

  13. Radiation myelopathy in patients treated for carcinoma of bronchus using a six fraction regime of radiotherapy

    International Nuclear Information System (INIS)

    The adoption of a six-fraction regime of radiotherapy for patients with locally advanced carcinoma of the bronchus was followed by the appearance of radiation myelitis in eight cases. These were among a group of 130 patients given radiotherapy with anterior and posterior treatment fields, without shielding of the spinal cord. Radiation myelitis was found only in those where the calculated spinal-cord dose exceeded 3350 cGy(rad). The possible precipitating factors in the eight patients who suffered myelopathy were compared with those in the remaining 62 patients who also received spinal-cord doses calculated to be greater than 3350 cGy(rad). Only one difference was found - the haemoglobin concentration was significantly higher in those who suffered neuropathy compared with those who did not (P=0.05). (U.K.)

  1. A Caucasian Australian presenting with human T-lymphotropic virus type I associated myelopathy: a case report

    Science.gov (United States)

    2014-01-01

    Introduction We report the first known case of human T-lymphotropic virus type I associated myelopathy/tropical spastic paraparesis in an Australian Caucasian, a disease reported in Aboriginal and immigrant populations where the virus is often endemic. Case presentation A 41-year-old Caucasian Australian man had a 3-year background of progressive functional decline from a myelopathy with spastic paraparesis and sphincteric dysfunction. Conclusions Although studies have shown a very low prevalence of human T-lymphotropic virus type I in the greater Australian population, increased focus on Aboriginal health, and the expanding diversity and integration of the Australian population means that presentation of human T-lymphotropic virus type I-associated disease is likely to increase.

    Treatment-requiring diseases of the cervical spine in children are rare. The most common cases requiring medical assessment and treatment are acute torticollis and various accidents. A torticollis having lasted for more than a week should be recognized, because it can be treated by skull traction. Cervical spine fractures in children under school age are very rare, the most common being a fracture of the base of the dens of the second cervical vertebra. Cervical spine instability is almost always associated with an underlying disease. PMID:27400588

    International Nuclear Information System (INIS)

    Glioblastoma multiforme (GBM) is the most common and most malignant primary brain tumour in adults. In spite of the hostile nature of glioblastoma multiforme (GBM), extracranial spread is not a common event. With improving management choices and survival times, reports of extracranial occurrence of GBM have increased. Most commonly these metastases are to the lungs, lymph nodes, neck, skull, scalp, liver, and bones; may be evident on routine follow-up images of the original lesion. Head and neck metastasis of GBM can be debilitating. We present a case of cervical metastasis of GBM and discuss possible mechanisms of extraneural spread of this tumour. (author)

    Curative-intent radical radiotherapy of cervical cancer consists of external-beam radiotherapy, brachytherapy, and concomitant chemotherapy with cisplatin. For each element, new developments aim to improve tumor control rates or treatment tolerance. Intensity-modulated radiotherapy (IMRT) has been shown to reduce gastrointestinal toxicity and can be used to selectively increase the radiotherapy dose. Individualized, image-guided brachytherapy enables better adaptation of high-dose volumes to the tumor extension. Intensification of concomitant or sequential systemic therapy is under evaluation.

    2014-01-01

    Full Text Available Background: Cages have been widely used for the anterior reconstruction and fusion of cervical spine. Nonmetal cages have become popular due to prominent stress shielding and high rate of subsidence of metallic cages. This study aims to assess fusion with n-HA/PA66 cage following one level anterior cervical discectomy. Materials and Methods: Forty seven consecutive patients with radiculopathy or myelopathy underwent single level ACDF using n-HA/PA66 cage. We measured the segmental lordosis and intervertebral disc height on preoperative radiographs and then calculated the loss of segmental lordosis correction and cage subsidence over followup. Fusion status was evaluated on CT scans. Odom criteria, Japanese Orthopedic Association (JOA and Visual Analog Pain Scales (VAS scores were used to assess the clinical results. Statistically quantitative data were analyzed while Categorical data by χ2 test. Results: Mean correction of segmental lordosis from surgery was 6.9 ± 3.0° with a mean loss of correction of 1.7 ± 1.9°. Mean cage subsidence was 1.2 ± 0.6 mm and the rate of cage subsidence (>2 mm was 2%. The rate of fusion success was 100%. No significant difference was found on clinical or radiographic outcomes between the patients (n=27 who were fused by n-HA/PA66 cage with pure local bone and the ones (n=20 with hybrid bone (local bone associating with bone from iliac crest. Conclusions: The n-HA/PA66 cage is a satisfactory reconstructing implant after anterior cervical discectomy, which can effectively promote bone graft fusion and prevent cage subsidence.

    Monoclonal antibodies such as bevacizumab are widely used in medical oncology, either alone or in combination with chemotherapy. No specific recommendations on the management of monoclonal antibodies extravasation exist. Incidence rates vary considerably. Estimates of 0.5-6% have been reported in the literature. Also, patient-associated and procedure-associated risk factors of extravasation are multiple, such as bolus injections or poorly implanted central venous access. We report on an 86-year-old woman with colon cancer with liver metastasis who was treated with 5-fluorouracil, folinic acid, and bevacizumab. Extravasation occurred during chemotherapy infusion because of a catheter migration of the port outside of the superior vena cava, causing cervical pain without skin modifications. Diagnosis was confirmed with the appearance of clinical right cervical tumefaction and cervicothoracic computed tomography scan indicated a perijugular hypodense collection, corresponding to the extravasation. Conservative management was proposed. The patient recovered within 3 weeks from all symptoms. Physicians should be aware that in cases of bevacizumab extravasation, a nonsurgical approach might be effective. PMID:23262983

    Full Text Available Introduction: Human T cell lymphotropic virus type I-associated myelopathy/tropical spastic paraparesis (HAM/TSP can impact the independence and motricity of patients. The aims of this study were to estimate the effects of physiotherapy on the functionality of patients with HAM/TSP during the stable phase of the disease using proprioceptive neuromuscular facilitation (PNF and to compare two methods of treatment delivery. Methods: Fourteen patients with human T cell lymphotropic virus type I (HTLV-I were randomly allocated into two groups. In group I (seven patients, PNF was applied by the therapist, facilitating the functional activities of rolling, sitting and standing, walking and climbing and descending stairs. In group II (seven patients, PNF was self-administered using an elastic tube, and the same activities were facilitated. Experiments were conducted for 1h twice per week for 12 weeks. Low-back pain, a modified Ashworth scale, the functional independence measure (FIM and the timed up and go test (TUG were assessed before and after the interventions. Results: In the within-group evaluation, low-back pain was significantly reduced in both groups, the FIM improved in group II, and the results of the TUG improved in group I. In the inter-group analysis, only the tone was lower in group II than in group I. Conclusions: Both PNF protocols were effective in treating patients with HAM/TSP.

    Full Text Available Abstract Background Human T lymphotropic virus Type 1 (HTLV-1 causes a chronic inflammatory disease of the central nervous system known as HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM which resembles chronic spinal forms of multiple sclerosis (MS. The pathogenesis of HAM remains uncertain. To aid in the differential diagnosis of HAM and to identify pathogenetic mechanisms, we analysed the plasma proteome in asymptomatic HTLV-1 carriers (ACs, patients with HAM, uninfected controls, and patients with MS. We used surface-enhanced laser desorption-ionization (SELDI mass spectrometry to analyse the plasma proteome in 68 HTLV-1-infected individuals (in two non-overlapping sets, each comprising 17 patients with HAM and 17 ACs, 16 uninfected controls, and 11 patients with secondary progressive MS. Candidate biomarkers were identified by tandem Q-TOF mass spectrometry. Results The concentrations of three plasma proteins - high [β2-microglobulin], high [Calgranulin B], and low [apolipoprotein A2] - were specifically associated with HAM, independently of proviral load. The plasma [β2-microglobulin] was positively correlated with disease severity. Conclusions The results indicate that monocytes are activated by contact with activated endothelium in HAM. Using β2-microglobulin and Calgranulin B alone we derive a diagnostic algorithm that correctly classified the disease status (presence or absence of HAM in 81% of HTLV-1-infected subjects in the cohort.

    2016-01-01

    Full Text Available Human T-lymphotropic virus type 1 (HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP is a chronic inflammatory disorder of the spinal cord. Acute cases of HAM/TSP and those complicated by movement disorders are rarely reported. Otherwise, psychiatric disturbances are very frequent in infected patients. It can evolve to psychogenic disorders. The case of a 46-year-old woman with acute HAM/TSP complicated by depression and psychogenic movement disorders (chorea of the hands and dystonia-like facial symptoms is reported. Brain magnetic resonance imaging revealed non-specific small white matter lesions. The involuntary movements arose suddenly and disappeared when the patient was distracted. Two years of psychotherapy and psychiatric follow-up induced complete remission of the symptoms. The association of psychogenic movement disorders and HAM/TSP, increasing the range of neurological manifestations associated with HTLV-1, is related here. Early diagnosis of psychogenic movement disorders is very important to improve the prognosis and treatment of the two conditions, thereby improving the quality of life of HAM/TSP patients and avoiding irreversible sequelae.

    Full Text Available Blau syndrome is a rare autoinflammatory disorder within the group of pediatric granulomatous diseases. Mutations in nucleotide-binding oligomerization domain 2 (NOD2/CARD15 are responsible for this condition, which has an autosomal dominant pattern of inheritance and variable expressivity. The clinical picture includes arthritis, uveitis, skin rash, and granulomatous inflammation. Central nervous system involvement is seldom reported, although some isolated cases of seizures, neurosensorial hearing loss, and transient cranial nerve palsy have been described. Treatment consists of nonsteroidal anti-inflammatory drugs, corticosteroids, and immunosuppressive agents, among which anti-tumor-necrosis-factor-alpha (TNF-α biologic agents, such as etanercept, play an important role. Among the major adverse effects of TNF-α inhibitors, demyelinating disease, multiple sclerosis, and acute transverse myelitis have been reported in adults. We describe a case of pediatric Blau syndrome affected by etanercept-induced myelopathy, manifesting as a clinical syndrome of transverse myelitis. The patient experienced rapid recovery after etanercept was discontinued. To our knowledge, this is the first such case reported in the literature and, possibly, the one with the latest onset, following 8 years of treatment. We discuss the etiopathogenic mechanisms of this reaction and possible explanations for the imaging findings.

  17. Possible etiologies for tropical spastic paraparesis and human T lymphotropic virus I-associated myelopathy

    Full Text Available The epidemiology of tropical spastic paraparesis/human T lymphotropic virus I (HTLV-I-associated myelopathy (TSP/HAM is frequently inconsistent and suggests environmental factors in the etiology of these syndromes. The neuropathology corresponds to a toxometabolic or autoimmune process and possibly not to a viral disease. Some logical hypotheses about the etiology and physiopathology of TSP and HAM are proposed. Glutamate-mediated excitotoxicity, central distal axonopathies, cassava, lathyrism and cycad toxicity may explain most cases of TSP. The damage caused to astrocytes and to the blood-brain barrier by HTLV-I plus xenobiotics may explain most cases of HAM. Analysis of the HTLV-I/xenobiotic ratio clarifies most of the paradoxical epidemiology of TSP and HAM. Modern neurotoxicology, neuroimmunology and molecular biology may explain the neuropathology of TSP and HAM. It is quite possible that there are other xenobiotics implicated in the etiology of some TSP/HAMs. The prevention of these syndromes appears to be possible today.

    Full Text Available Cervical spondylosis is a common, chronic degenerative condition of the cervical spine that affects the vertebral bodies and intervertebral disks of the neck as well as the contents of the spinal canal. Common clinical syndromes associated with cervical spondylosis include cervical pain, cervical radiculopathy and/or mielopathy. This study show the main principles, indication and side effects of tuina in cervical spondylosis´ treatment; tuina is one of the external methods based on the principles of Traditional Chinese Medicine (TCM, especially suitable for use on the elderly population and on infants. While performing Tuina, the therapist concentrates his mind, regulates his breathing, and actuates the Qi and power of his entire body towards his hands. For a better result is recommended to try to combine acupuncture with tuina treatment. Tuina can help relieve the pain associated with spondylosis. After this kind of treatment, the symptomes produced by irritated nerves and sore muscles can find some relief. Tuina helps patients with cervical spondylosis regain muscle control, nerve function and flexibility, all through the restoration of the life force flow.

    Objective: The role of human papillomavirus (HPV) in the development of cervical carcinoma has been clearly established but other factors could be involved in cervical tumorigenesis such as loss of heterozygosity (LOH) and microsatellite instability (MI). The aim of the present study was to investigate the genetic instability in cervical carcinoma tissues and provide evidence for discoveringnew tumor suppressor genes and screening diagnostic molecular marker of cervical carcinoma. Methods: Fifty primary cervical carcinoma samples from high-incidence area were analyzed by PCR for HPV16 infection, LOH and microsatellite instability. Results: HPV16 was detected in 88% of the cases. Sixty-six percent of total cases showed LOH with no more than 3 different loci per case. The highest frequency of the allelic loss was found in D18S474 (18q21, 40.5%). MI was detected in 4 cases (8%) only. Conclusion: Different percentages of LOH on specific chromosomal regions were found and MI was very infrequent in cervical carcinoma. The putative suppressor gene(s) could be located on specific chromosome regions such as 18q, and genetic instability could be involved in cervical tumorigenesis.

    Cervical screening has been one of the most successful public health prevention programmes. For 50 years, cytology formed the basis for screening, and detected cervical intraepithelial lesions (CIN) were treated surgically to prevent progression to cancer. In a high-risk country as Denmark......, screening decreased the incidence of cervical cancer from 34 to 11 per 100,000, age-standardized rate (World Standard Population). Screening is, however, also expensive; Denmark (population: 5.6 million) undertakes close to half a million tests per year, and has 6-8 CIN-treated women for each prevented...... cancer case. The discovery of human papillomavirus (HPV) as the cause of cervical cancer dramatically changed perspectives for disease control. Screening with HPV testing was launched around 1990, and preventive HPV vaccination was licensed in 2006. Long-term randomized controlled trials (RCT...

    Ipilimumab is a novel humanized monoclonal antibody directed against cytotoxic T lymphocyte antigen 4, a T-cell surface molecule involved in down-regulation and suppression of the T cell response to stimuli. Patients treated with ipilimumab are at risk for immune-related adverse events involving the skin, digestive tract, liver and endocrine organs. Few case reports of immune-related adverse effects involving central or peripheral nervous system due to ipilimumab are published. These include inflammatory myopathy, aseptic meningitis, severe meningo-radiculo-neuritis, temporal arteritis, Guillain-Barre syndrome, and posterior reversible encephalopathy syndrome. We report the first case of ipilimumab-induced progressive necrotic myelopathy. PMID:25712627

    In 1980, Human T cell leukemia/lymphoma virus type 1 (HTLV-1) was the first oncogenic human retrovirus to be discovered. HTLV-1 belongs to the Retroviridae family, the Orthoretrovirinae subfamily and to the deltaretrovirus genus. HTLV-1 preferentially infects CD4(+) lymphoid cells in vivo. Three molecules have been identified for binding and/or entry of HTLV-1: heparan sulfate proteoglycans, neuropilin-1, and glucose transporter 1. An efficient transfer of the virus from an infected cell to a target cell can occur through the formation of a viral synapse and/or by virofilm structure. As for all retroviruses, HTLV-1 genome possesses three major ORFs (gag, pol and env) encoding the structural and enzymatic proteins. HTLV-1 encodes also some regulatory and auxillary proteins including the tax protein with transforming activities and the HBZ protein which plays a role in the proliferation and maintenance of the leukemic cells. HTLV-1 is present throughout the world with clusters of high endemicity including mainly Southern Japan, the Caribbean region, areas in South America and in intertropical Africa. The worldwide HTLV-1 infected population is estimated to be around 10-20 million. HTLV-1 has three modes of transmission: (1): mother to child, mainly linked to prolonged breast-feeding; (2): sexual, mainly occurring from male to female and (3): contaminated blood products. HTLV-1 possesses a remarkable genetic stability. HTLV-1 is the etiological agent of mainly two severe diseases: a malignant T CD4(+) cell lymphoproliferation, of very poor prognosis, named Adult T cell Leukemia/Lymphoma (ATLL), and a chronic neuro-myelopathy named Tropical spastic paraparesis/HTLV-1 Associated Myelopathy (TSP/HAM). The lifetime risk among HTLV-1 carriers is estimated to be around 0.25 to 3%. TSP/HAM mainly occurs in adults, with a mean age at onset of 40-50 years and it is more common in women than in men. Blood transfusion is a major risk factor for TSP/HAM development. Clinically

  7. Two cases of cervical disc disease with intramedullary pathological changes, which are responsible for their neurological syndromes, on delayed CT myelography

    International Nuclear Information System (INIS)

    We report two cases of cervical disc disease with myelopathy classified as of motor system syndrome type showing small contrast accumulation within the spinal cord on delayed CT myelography. In our two cases, high density spots on delayed CT myelography were bilaterally localized within the spinal cord, and believed represent pathological changes of the spinal cord, such as collection of microcavities or cystic necrosis. In case 1, the high density areas seemed to be localized in the anterior horn and corticospinal tract, and in case 2, they seemed to be localized in the corticospinal tract. The patient in case 1 produced signs and symptoms resembling motor neurone disease and lesion could not be differentiated from the latter. Delayed CT myelography showed that the cause of the upper limb amyotrophy was attributed to an anterior horn disorder and that of pyramidal tract sign to a corticospinal tract disorder. Therefore, we could differentiate the lesion from motor neurone disease on delayed CT myelography in case 1. In conclusion, we emphasize that delayed CT myelography can demonstrate the intramedullary pathological changes in the cervical disc disease and is useful in distinguishing between cervical disc disease simulating motor neurone disease and the latter.

    Full Text Available Canine degenerative myelopathy (DM is a progressive disease process that is diagnosed late in life and mainly affects the pelvic limbs. Factors that make an ante-mortem definitive diagnosis of DM include: an insidious onset and clinical manifestation that mimics other disease processes of the pelvic limbs (hip dysplasia, cranial cruciate ligament rupture, etc. or there may even be concurrent disease processes, old-age onset and lack of reliable diagnostic methods. Until recently, South African dog owners had to submit samples to laboratories overseas for genetic testing in order to confirm an affected dog (homozygous A/A and to aid in the ante-mortem diagnosis of DM. Only affected dogs have been confirmed to manifest the clinical signs of DM. This study aimed to verify whether genetic testing by a local genetic laboratory was possible in order to detect a missense mutation of the superoxide dismutase gene (SOD1 that is implicated in causing the clinical signs of DM. The study also aimed to detect and map the inheritance of this disease process in a local Boxer dog population where the pedigree of the sampled population was known. Venous blood collected from Boxer dogs using a simple random sampling technique. The samples were genotyped for the SOD1:c.118G>A polymorphism. Carrier and affected Boxer dogs were detected. A pedigree that demonstrated the significance of inheriting a carrier or affected state in the population was mapped. The present study concludes that genotyping of the missense mutation in Boxer dogs is possible in South Africa. There are carrier and affected Boxer dogs in the local population, making DM a plausible diagnosis in aged dogs presenting with pelvic limb pathology.

    Purpose: Dose-volume histogram (DVH) results for 9 cases of post spine stereotactic body radiation therapy (SBRT) radiation myelopathy (RM) are reported and compared with a cohort of 66 spine SBRT patients without RM. Methods and Materials: DVH data were centrally analyzed according to the thecal sac point maximum (Pmax) volume, 0.1- to 1-cc volumes in increments of 0.1 cc, and to the 2 cc volume. 2-Gy biologically equivalent doses (nBED) were calculated using an {alpha}/{beta} = 2 Gy (units = Gy{sub 2/2}). For the 2 cohorts, the nBED means and distributions were compared using the t test and Mann-Whitney test, respectively. Significance (P<.05) was defined as concordance of both tests at each specified volume. A logistic regression model was developed to estimate the probability of RM using the dose distribution for a given volume. Results: Significant differences in both the means and distributions at the Pmax and up to the 0.8-cc volume were observed. Concordant significance was greatest for the Pmax volume. At the Pmax volume the fit of the logistic regression model, summarized by the area under the curve, was 0.87. A risk of RM of 5% or less was observed when limiting the thecal sac Pmax volume doses to 12.4 Gy in a single fraction, 17.0 Gy in 2 fractions, 20.3 Gy in 3 fractions, 23.0 Gy in 4 fractions, and 25.3 Gy in 5 fractions. Conclusion: We report the first logistic regression model yielding estimates for the probability of human RM specific to SBRT.

  11. Analysis of digitized cervical images to detect cervical neoplasia

    Ferris, Daron G.

    2004-05-01

    Cervical cancer is the second most common malignancy in women worldwide. If diagnosed in the premalignant stage, cure is invariably assured. Although the Papanicolaou (Pap) smear has significantly reduced the incidence of cervical cancer where implemented, the test is only moderately sensitive, highly subjective and skilled-labor intensive. Newer optical screening tests (cervicography, direct visual inspection and speculoscopy), including fluorescent and reflective spectroscopy, are fraught with certain weaknesses. Yet, the integration of optical probes for the detection and discrimination of cervical neoplasia with automated image analysis methods may provide an effective screening tool for early detection of cervical cancer, particularly in resource poor nations. Investigative studies are needed to validate the potential for automated classification and recognition algorithms. By applying image analysis techniques for registration, segmentation, pattern recognition, and classification, cervical neoplasia may be reliably discriminated from normal epithelium. The National Cancer Institute (NCI), in cooperation with the National Library of Medicine (NLM), has embarked on a program to begin this and other similar investigative studies.

    Full Text Available ABSTRACT HTLV-1-associated myelopathy is a progressive disabling disease associated with gait abnormalities. Objective To identify and quantify the main muscles affected by weakness and spasticity, their impact on gait, functional capacity and on quality of life of HTLV-1-associated myelopathy patients. Method We evaluated lower limbs muscular strength according to the Medical Research Council scale, spasticity according to the modified Ashworth scale, daily activities according to the Barthel Index and quality of life according to the Short-Form Health Survey-36 of 26 HTLV-1-associated myelopathy patients. Results The muscles most affected by weakness included the dorsal flexors and knee flexors. Spasticity predominated in the hip adductor muscles and in plantar flexors. Assistance for locomotion, minimal dependence in daily activities, limitations in functional capacity and physical aspects were the most common findings. Conclusion The impairment of gait, functional dependence and quality of life were predominantly a consequence of intense muscle weakness in HTLV-1-associated myelopathy patients.

    Today we can state that in spite of a considerable number of cervical osteochondrosis studies, there is a lack of research devoted to analysis of its course. There is no correlation between initial expert evaluations of cervical osteo-chondrosis cases and further course of pathological process. Goal of the research is to develop system of course prognosis of cervical osteochondrosis taking into account environmental infuence, heredity, living conditions, psychological profle of patient’s personality. Materials and methods. Dynamics of degenerative-dystrophic changes progressing of cervical vertebrae in 236 patients was analyzed. Results. Received data demonstrated that probability of stage I changing to stage II, III and IV depended on patients’ sex, age and type of labour activity, frequent supercooling and stress. Probability of fast progression of cervical osteochondrosis (5-year cycle of stage I changing to stage III and IV was to a great extent associated with heredity, urban living, presence of endocrine system diseases, syndrome of nonspecifc dysplasia of connective tissue and low indices of quality of life. Conclusion. Proposed system allows making prognosis of morphologic changes in spinal cord, and is based on radiation methods of verifcation without taking into consideration dynamics of neurological symptomatology.

    2008-01-01

    Full Text Available Simultaneous presence of congenital irreducible atlantoaxial dislocation (AAD and cervical intramedullary astrocytoma has not been previously described and may cause disabling myelopathy. This 55-year-old lady presented with suboccipital pain, spastic quadriparesis, Lhermitte′s phenomenon and sphincteric disturbances. Lateral radiographs and magnetic resonance imaging showed irreducible AAD, occipitalized atlas, C2-3 fusion, and,an intramedullary tumor from C2-5 level iso-to-hypointense, non-enhancing, except in a small segment in the dorsal C2 level. A suboccipital craniectomy with C2-5 laminectomy revealed a greyish-white tenacious tumor. The tumor was decompressed using a C2-5 midline myelotomy and duroplasty. An occipitocervical lateral mass fixation was performed. Histopathology revealed a low-grade astrocytoma. At three-month follow-up, her spasticity had decreased and quadriparesis and sphincteric disturbances were persisting. Postoperative lateral radiographs and intrathecal contrast CT scan showed a stable occipitocervical construct. Thus, the suboccipital craniectomy and laminectomy with midline myelotomy and duroplasty facilitated space for progressively expanding intramedullary astrocytoma with irreducible AAD; the lateral mass fixation provided stability at the craniovertebral junction.

  4. Comparison of MRI pulse sequences for investigation of lesions of the cervical spinal cord

    International Nuclear Information System (INIS)

    Small spinal cord lesions, even if clinically significant, can be due to the low sensitivity of some pulse sequences. We compared T2-weighted fast (FSE), and conventional (CSE) spin-echo and short-tau inversion-recovery (STIR)-FSE overlooked on MRI sequences to evaluate their sensitivity to and specificity for lesions of different types. We compared the three sequences in MRI of 57 patients with cervical spinal symptoms. The image sets were assessed by two of us individually for final diagnosis, lesion detectability and image quality. Both readers arrived at the same final diagnoses with all sequences, differentiating four groups of patients. Group 1 (30 patients, 53 %), with a final diagnosis of multiple sclerosis (MS). Demyelinating lesions were better seen on STIR-FSE images, on which the number of lesions was significantly higher than on FSE, while the FSE and CSE images showed approximately equal numbers of lesions; additional lesions were found in 9 patients. The contrast-to-noise ratio (CNR) of 17 demyelinating lesions was significantly higher on STIR-FSE images than with the other sequences. Group 2, 19 patients (33 %) with cervical pain, 15 of whom had disc protrusion or herniation: herniated discs were equally well delineated with all sequences, with better myelographic effect on FSE. In five patients with intrinsic spinal cord abnormalities, the conspicuity and demarcation of the lesions were similar with STIR-FSE and FSE. Group 3, 4 patients (7 %) with acute myelopathy of unknown aetiology. In two patients, STIR-FSE gave better demarcation of lesions and in one a questionable additional lesions. Group 4, 4 patients (7 %) with miscellaneous final diagnoses. STIR-FSE had high sensitivity to demyelinating lesions, can be considered quite specific and should be included in spinal MRI for assessment of suspected demyelinating disease. (orig.)

We compared T2-weighted fast (FSE), and conventional (CSE) spin-echo and short-tau inversion-recovery (STIR)-FSE overlooked on MRI sequences to evaluate their sensitivity to and specificity for lesions of different types. We compared the three sequences in MRI of 57 patients with cervical spinal symptoms. The image sets were assessed by two of us individually for final diagnosis, lesion detectability and image quality. Both readers arrived at the same final diagnoses with all sequences, differentiating four groups of patients. Group 1 (30 patients, 53 %), with a final diagnosis of multiple sclerosis (MS). Demyelinating lesions were better seen on STIR-FSE images, on which the number of lesions was significantly higher than on FSE, while the FSE and CSE images showed approximately equal numbers of lesions; additional lesions were found in 9 patients. The contrast-to-noise ratio (CNR) of 17 demyelinating lesions was significantly higher on STIR-FSE images than with the other sequences. Group 2, 19 patients (33 %) with cervical pain, 15 of whom had disc protrusion or herniation: herniated discs were equally well delineated with all sequences, with better myelographic effect on FSE. In five patients with intrinsic spinal cord abnormalities, the conspicuity and demarcation of the lesions were similar with STIR-FSE and FSE. Group 3, 4 patients (7 %) with acute myelopathy of unknown aetiology. In two patients, STIR-FSE gave better demarcation of lesions and in one a questionable additional lesions. Group 4, 4 patients (7 %) with miscellaneous final diagnoses. STIR-FSE had high sensitivity to demyelinating lesions, can be considered quite specific and should be included in spinal MRI for assessment of suspected demyelinating disease. (orig.)

    Full Text Available Background: Enlarged palpable cervical lymph nodes as a primary presenting sign are very common and may be due to inflammatory lesions and tumors. Correlation between clinical findings and laboratory data is essential in arriving at a diagnosis. In patients presenting with cervical lymphadenopathy, excision biopsy provides material to establish an early diagnosis. We designed this study in our population for histological evaluation of cervical lymph node biopsies that might be important in the management of these patients. Objective: Histopathological evaluation of different diseases involving the cervical lymph nodes in relation to age and sex of the study population. Materials and Methods: It was a cross sectional study conducted in the department of Pathology, Enam Medical College & Hospital, Savar, Dhaka during the period from January 2006 to December 2010. A total of 107 patients were evaluated for specific cause of cervical lymphadenopathy in relation to age and sex. Lymph node biopsies of all patients of both sexes and all age groups were included in the study. Results: Among the 107 subjects 58 (54.2% were males and 49 (45.8% were females with a male to female ratio of 1.2:1. The age of the patients ranged from 2 to 85 years with a mean age of 32.68 ± 18.01 years. Of the 107 lymph node biopsies, 34 cases (31.8% were reactive lymphadenitis, 41 cases (38.3% were tuberculosis, 2 cases (1.9% were non-caseous granuloma, 6 cases (5.6% were Hodgkin lymphoma, 8 cases (7.5% were non-Hodgkin lymphoma, 12 cases (11.2% were metastatic neoplasm and 4 cases (3.7% were other specific lesions. Conclusion: The commonest cause of cervical lymphadenopathy was tuberculosis, followed by reactive lymphadenitis, lymphoma and metastatic neoplasm.

    Background Lower cervical dislocation with locked facets is common in cervical injury. The locked facets include unilateral and bilateral types. Different successful closed reduction rates has been achieved between unilateral and bilateral types by using rapid skull traction, which was commonly used to reduce the cervical dislocation. It is important to investigate a suitable management specific to patients with different types of cervical locked facets.Methods A total of 38 patients with cervical dislocation with locked facet due to cervical injury treated by rapid skull traction and operation from 1988 to 2005 were reviewed. Rapid skull traction was used in all the patients. Successful closed reduction rate was 88.0% in patients with bilateral cervical locked facets and that was 15.4% in those with unilateral cervical locked facets. These data were then statistically compared by Chi-square test. Patients who were reduced successfully underwent anterior cervical discectomy and fusion at the injured level, and those who failed in closed reduction received posterior open reduction and fixation.Results In this series, there was statistically significant difference (P<0.05) in the rate of successful closed skull traction reduction between unilateral and bilateral locked facets dislocation. Unilateral cervical locked facets dislocation was not easily reduced by skull traction which was suitable for reduction of bilateral cervical locked facets dislocation. However,unilateral cervical locked facets dislocation can be reduced by posterior open reduction.Conclusions Unilateral cervical locked facets dislocation should be treated immediately with posterior open reduction and instrumentation. Bilateral cervical locked facets dislocation can be reduced by rapid skull traction firstly and anterior cervical discectomy and interbody fusion later.

  10. Human papillomavirus testing in cervical cancer screening.

    Science.gov (United States)

    Castle, Philip E; Cremer, Miriam

    2013-06-01

    Human papillomavirus (HPV) testing is more reliable and sensitive but less specific than Papanicolaou (Pap) testing/cervical cytology for the detection of cervical precancer and cancer. HPV-negative women are at lower risk of cervical cancer than Pap-negative women. In high-resource settings, HPV testing can be used to make cervical cancer prevention programs more efficient by focusing clinical attention on women who have HPV. In lower-resource settings, where Pap testing has not been sustained or widespread, new, lower-cost HPV tests may make cervical cancer screening feasible. PMID:23732037

    Cervical spine injuries of children, though rare, have a high morbidity and mortality. The pediatric cervical spine is anatomically and biomechanically different from that of adults. Hence, the type, level and outcome of cervical spine injuries in children are different from those seen in adults. Normal developmental variants seen in children can make evaluation of the pediatric cervical spine challenging. This article reviews the epidemiology of pediatric cervical spine trauma, normal variants seen in children and specific injuries that are more common in the pediatric population. We also propose an evidence-based imaging protocol to avoid unnecessary imaging studies and minimize radiation exposure in children. (orig.)

    Most upper esophageal malignancies are squamous cell carcinomas, rarely adenocarcinomas arising from Barrett's esophagus and very rarely adenocarcinomas from heterotopic gastric mucosa without evidence of Barrett's especially in the cervical part of the esophagus. We report a case of adenocarcinoma of the polypoid type in the upper esophagus (cervical esophagus) arising from ectopic gastric mucosa, in a 60 year-old man who presented with progressive dysphagia. Accurate diagnosis by esophagogram revealed a large mass in the cervical esophagus; CAT scan showed intraluminal mass at the level of thoracic inlet, esophagogastroscopy showed a fleshy polyp (3.2cm x 3.0cm) at 20 cm from the incisors with a biopsy confirming moderately differentiated adenocarcinoma with no evidence of Barrett's esophagus. Through a left cervical approach and resection of medial third of clavicle, the tumor was removed by partial esophagectomy followed by lymph node dissection, and proved to be T1NOMO, stage I (AJCC staging 6th ed.). Post operatively, the patient received chemoradiation with no evidence of recurrence or metastasis in six years of follow up. It seems this tumor has a much better prognosis than adenocarcinomas arising from Barrett's. To our knowledge only 19 cases have been reported in literature so far. PMID:16110768

    The aim of this study was to describe the method and the value of cervical discography as correlated with the MR findings. Twenty-one discs in 11 consecutive patients who underwent cervical discography were analyzed. MR and CT discography (CTD) were performed in all patients. Discography was performed after swallowing barium for visualizing the pharynx and the esophagus to prevent penetration. We also analyzed the preceding causes of the subjects' cervical pain. The results of the pain provocation test were classified into concordant pain, discordant pain and a negative test. MRI was analyzed according to the T2-signal intensity (SI) of the disc, disc height, annular bulging and disc herniation. The CTD was analyzed for degeneration or radial tear of the disc, epidural leakage of the contrast agent and pooling of the contrast agent at the periphery of the disc. The pain provocation tests were correlated with the MR and CTD findings. We used the chi-square test to analyze the results. Concordant pain was observed in 14 cases, discordant pain in 3 cases and there were negative tests in 4 cases. There were no complications related to the procedure. Four patients had undergone anterior cervical fusion and four patients that developed after traffic injuries. The decreased T2-SI and annular bulging on MRI, disc degeneration and peripheral pooling of the contrast agent on CT were significantly correlated with pain provocation. When the diagnosis of disc disease is difficult with performing MRI, cervical discography with using swallowed barium solution to reduce the penetration of the esophagus or hypopharynx may play be helpful. The decreased T2-SI and annular bulging on MRI correlated significantly with a positive result on the pain provocation test.

  1. A new model of radiation-induced myelopathy: A comparison of the response of mature and immature pigs

    International Nuclear Information System (INIS)

    The purpose was development of an experimental model of radiation-induced myelopathy in the pig which would facilitate the study of the effects of clinically relevant treatment volumes. The effects of local spinal cord irradiation, to a standard 10 X 5 cm field, have been evaluated in mature (37-42.5 weeks) and immature (15.5-23 weeks) pigs. Irradiation was with single doses of 60Co γrays at a dose-rate of 0.21-0.65 Gy/min. The incidence of paralysis was used as an endpoint. Irradiation of mature animals resulted in the development of frank paralysis with animals showing combined parenchymal and vascular pathologic changes in their white matter. These lesions, in common with those seen in patients, had a clear evidence of an inflammatory component. The latency for paralysis was short, 7.5-16.5 weeks, but within the wide range reported for patients. However, it was shorter than that reported in other large animal models. The ED50 value (±SE) for paralysis was 27.02±0.36 Gy, similar to that in rats taking into account dose-rate factors. The irradiation of immature pigs only resulted in transient neurological changes after doses comparable to those used in the mature animals, ED50 value (±SE) 26.09±0.37 Gy. The reasons for these transient neurological symptoms are uncertain. A reliable experimental model of radiation-induced myelopathy has been developed for mature pigs. This model is suitable for the study of clinically relevant volume effects. 39 refs., 4 figs., 1 tab

    1992-02-01

    Of twenty-two patients who had had anterior decompression of the spinal canal for ossification of the posterior longitudinal ligament and cervical myelopathy, seven had absence of the dura adjacent to the ossified part of the ligament. The spinal cord and nerve-roots were visible through this defect. Although the arachnoid membrane appeared to be intact and watertight in most patients, a cerebrospinal-fluid fistula developed postoperatively in five, and three had a second operation to repair the defect in the dura. On the basis of this experience, we recommend use of autogenous muscle or fascial dural patches, immediate lumbar subarachnoid shunting, and modification of the usual postoperative regimen, such as limitation of mechanical pulmonary ventilation to the shortest time that is safely possible and use of anti-emetic and antitussive medications to protect the remaining coverings of the spinal cord when the dura is found to be absent adjacent to an ossified portion of the posterior longitudinal ligament in the cervical spine.

    Background It was reported that telomerase expression is closely associated with cellular immortality and cancer. This study was designed to investigate the relationship between telomerase expression and the carcinogenesis of cervical cancer, the possible use of telomerase as a marker of cervical intraepithelial neoplasia (CIN) progression or regression, and the natural history of CIN. Methods Telomeric repeat amplification protocol (TRAP) assay was used to measure telomerase activity in cervical scrapings and biopsy samples obtained from 105 cases affected with various cervical conditions, including chronic cervicitis (n=20), CIN (n=64, 16 cases of CIN Ⅰ , 20 cases of CIN Ⅱ, and 28 cases of CIN Ⅲ ), and invasive squamous cell carcinoma (n =21 ).Results In exfoliated cell samples, telomerase activity was detected in 5 of 20 (25. 0% ) cases of cervicitis, 10 of 16 (62.5%) cases of CIN Ⅰ , 11 of 20 (55.0%) cases of CIN Ⅱ, 23 of 28 (82.1%) cases of CIN Ⅲ, and 13 of 21 (61.9%) cases of carcinoma. In cervical biopsy samples, telomerase activity was detected in 6 of 20 (30. 0%) cases of cervicitis, 8 of 16 (50. 0%) cases of CIN Ⅰ , 9 of 20 (45.0%) cases of (CIN Ⅱ, 27 of 28 (96. 4%) cases of CIN Ⅲ, and 20 of 21 (95. 2%) cases of carcinoma. Telomerase activation was significantly higher in CIN samples than in cervicitis samples. Telomerase activity was detected at similar frequency in samples from cervical scrapings and cervical biopsies.Conclusion These results seem to suggest that telomerase expression may be associated with carcinogenesis of the cervix. TRAP assay of cervical scraping samples could be used to monitor and predict the development of CIN in clinical practice.

    Instrumentation of the cervical spine enhances stability and improves arthrodesis rates in children undergoing surgery for deformity or instability. Various morphologic and clinical studies have been conducted in children, confirming the feasibility of anterior or posterior instrumentation of the cervical spine with modern implants. Knowledge of the relevant spine anatomy and preoperative imaging studies can aid the clinician in understanding the pitfalls of instrumentation for each patient. Preoperative planning, intraoperative positioning, and adherence to strict surgical techniques are required given the small size of children. Instrumentation options include anterior plating, occipital plating, and a variety of posterior screw techniques. Complications related to screw malposition include injury to the vertebral artery, neurologic injury, and instrumentation failure. PMID:27097300

    Despite the development of screening and of a vaccine, cervix cancer is a major cause of cancer death in young women worldwide. A third of women treated for the disease will recur, almost inevitably leading to death. Functional imaging has the potential to stratify patients at higher risk of poor response or relapse by improved delineation of disease extent and tumor characteristics. A number of molecular imaging biomarkers have been shown to predict outcome at baseline and/or early during therapy in cervical cancer. In future this could help tailor the treatment plan which could include selection of patients for close follow up, adjuvant therapy or trial entry for novel agents or adaptive clinical trials. The use of molecular imaging techniques, FDG PET/CT and functional MRI, in staging and response assessment of cervical cancer is reviewed. PMID:26859085

    Objective: To evaluate factors for prognosis of cervical carcinoma. Methods: Expressions of mn23- HI, erbB3 and erbB4 were examined by immunohistochemical staining. The apoptosis was detected in situ by the TdT mediated duip-biotin nick end-labeling (TUNEL) technique. Mitotic cell were counted by HE dyeing. Results: FIGO stage and lymph node metastasis were the most important factors for evaluating prognosis in adenocarcinoma or squamous cell carcinoma. AI/MI was positively correlated with 5-year survival of cervical carcinoma. Positive expression of nm23-H1 combed with negative expression of erbB4 [nm23-H1(+)/erbB4(-)] predicted good prognosis for adeno-carcinoma. In multivariable Cox regression analysis, only FIGO stage and AI/MI were into equation. Conclusion: FIGO stage and AI/MI were independent evaluating parameter for adenocarcinoma or squamous cell carcinoma.

  19. Triple spontaneous cervical artery dissection

    International Nuclear Information System (INIS)

    A 39-year-old healthy man had several transient ischaemic attacks suggesting left internal carotid artery (ICA) occlusion. There were no vascular risk factors and no preceding trauma. Colour-coded duplex sonography suggested a pseudo-occlusion of the left ICA, and cerebral angiography demonstrated dissection of the left ICA and both vertebral arteries. Angiography 6 months later was completely normal. This underlines the importance of four vessel angiography in young patients with dissections of cervical arteries. (orig.)

    Morgan Lorio, MD, FACS, Chair, ISASS Task Force on Coding & Reimbursement In 2011, CPT code 22551 was revised to combine or bundle CPT codes 63075 and 22554 when both procedures were performed at the same site/same surgical session. The add on code +22552 is used to report each additional interspace. 2014 heralded a downward pressure on this now prime target code (for non-coverage?) 22551 through an egregious insurer attempt to redefine cervical arthrodesis, effectively removing spine surgeon...
