Atypical cervical spondylotic radiculopathy resulting in a hypertensive emergency during cervical extension: A case report and review of literature

BACKGROUND Extensive research revealed the absence of reports documenting hypertensive emergencies precipitated by changes in the cervical spine posture.CASE SUMMARY We here present a 57-year-old woman diagnosed as having cervical spondylotic radiculopathy(CSR)who was scheduled for anterior cervical decompression and fusion.During post-anesthetic positioning,a sudden hypertensive surge was observed when the patient was in a supine position with the neck being slightly extended.This surge was promptly reversed through cervical flexion and head elevation.This event however required an alternate surgical approach for recovery—posterior laminoplasty and endoscopy-assisted nucleus pulposus removal.Following the 6-month outpatient follow-up period,cervical flexion and extension activities substantially improved in the patient without any episodes of increase in acute blood pressure.CONCLUSION Maintaining a safe hypotensive posture and performing rapid,thorough deco-mpression surgery may serve as effective interventions for patients presenting symptoms similar to those of CSR accompanied by hypertensive emergencies(HE).This would mitigate the underlying causes of these HEs.

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

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.

Application of magnetic resonance imaging in cervical spondylotic myelopathy

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.

Cervical spondylotic myelopathy with syringomyelia presenting as hip Charcot neuroarthropathy:A case report and review of literature

BACKGROUND Charcot neuroarthropathy(CN)is a systemic disease characterized by progressive bone loss and destruction,which is usually closely related to diabetes,HIV,etc.However,CN caused by syringomyelia accounts for only 5%of CN cases;the shoulder and elbow are most often involved,and the hip joint is rarely affected.As a rare factor,cervical spondylotic myelopathy(CSM)can be associated with syringomyelia,which is scarcely reported in the literature.Here,we present the first case report to date of CN of the hip caused by syringomyelia secondary to CSM.CASE SUMMARY We describe a 76-year-old male patient who was diagnosed with CSM due to neck pain and weakness of limbs 16 years ago.Four years ago,he noticed recurrent swelling of the right hip with pain and was diagnosed with degenerative arthritis.Recently,however,his symptoms gradually worsened,and because of progressive pain,destabilization and weakness of the right hip,he was admitted to our hospital.Through systematic physical,radiographic and laboratory examinations,we finally reached a diagnosis:CN of the right hip associated with syringomyelia secondary to CSM.After comprehensive evaluation of the patient's condition,we performed right total hip arthroplasty.During the follow-up,the patient felt well clinically and could walk independently with a knee brace.CONCLUSION We suggest a possible etiological association between CSM and syringomyelia,which may reflect a potential pathogenesis of CN.We encourage clinicians to actively carry out a detailed medical history and comprehensive physical and imaging examinations in patients with joint lesions,especially chronic shoulder neck pain,to rule out the possibility of this association,which plays a crucial role in the early diagnosis of CN.Arthroplasty may no longer be an absolute contraindication to surgical treatment of CN.Reasonable selection of the surgical strategy can markedly improve the clinical symptoms and quality of life of patients.

Application of anterior decompression and reconstruction using titanium mesh with locking plates in the management of cervical spondylotic myelopathy

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 improvement 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.

Effect of Exercise Program on the Rehabilitation of Patients with Cervical Spondylotic Myelopathy

Study Design: A clinical trial of 30 consecutive patients with cervical spondylotic myelopathy (CSM). Objectives: To evaluate the effect of directed physical exercise in patients with CSM and to measure severity of myelopathy before and after an exercise program. Setting: Christian Medical College and Hospital, India. Participants: Thirty patients with CSM (mean age-54.1 years) with Nuricks Grade 2 and 3. Background: Myelopathy of the spinal cord can be caused by degenerative process of the cervical vertebrae and it is the most common type of dysfunction of the spinal cord in adult population. CSM usually develops insidiously and the natural history is not well understood, there is debate over the indication for operative Vs non operative management. Method: Patients participated in a 6-week exercise program, consisting of active exercises to upper and lower extremities, scapulothoracic muscles, and gentle stretches, sub maximal isometric exercises of the deep neck flexors, relaxation and immobilization with a cervical collar. Main Outcome Measures: The mJOA (modified Japanese orthopaedic association score) and ASIA motor and sensory scoring. The results were processed by using Wilcoxon sign rank test. Results: After comparing the values at the beginning and end of the program a satisfactory neurological result (sensorimotor/motor and sensory) was obtained in all thirty patients. Conclusion: The exercise program had a positive impact for most of the variables of the study. Exercise intervention with neck immobilization may be a treatment of choice in early stages of CSM. Future randomized controlled studies would provide insight into the effectiveness and clinical relevance of this intervention.

CLINICAL STUDY ON TREATMENT OF CERVICAL SPONDYLOTIC SYNDROME WITH BEETLE NEEDLE

The authors treated 68 cases of cervical spondylotic syndrome with beetle nee-dle,a new needle apparatus(made by themselves)which is not inserted into the skin of the humanbody.A total of 15 sessions of treatment were given to every patient.Results showed that 56 cases(82％)were cured,7 cases(10.3％)improved and 5 cases(7.4％)invalid.Just as its name implies,the beetle is instead of acupuncture needle.All the diseases being able to be treated with acupunctureneedle could also be treated with beetle needle.In addition,the beetle needle therapy has no violentpain,is safe,effective and easy to be popularized. It also has no harm to viscerae,no cross infection,no dangers of broken needle and of failing during treatment,so,the patient needs not to be in fear.The therapy is preferable for patients to accept.

Functional evaluation using several evoked spinal cord potentials in elderly patients with cervical spondylotic myelopathy

BACKGROUND ： The recordings of evoked spinal cord potentials following epidural spinal cord stimulation are thought to be generated by volleys traversing the dorsal column pathway, and it may not directly reflect conduction defects in corticospinat tracts of cervical spinal cord. To our knowledge there has been few report using several evoked spinal cord potentials in function evaluation of the cervical spinal cord in eldedy patients with cervical spondylotic myelopathy （CSM）. OBJECTIVE： To investigate the function states of the cervical spinal cord in elderly patients with CSM and explore its pathophysictogic mechanism. DESIGN： Case observation SETTING ： Department of Orthopedics for the aged, Shenzhen Pingle Hospital of Orthopedics. Department of Orthopedic Surgery, Yamaguchi University School of Medicine. PARTICIPANTS ： A total of 23 eldedy patients with CSM who received treatment in the Department of Orthopedic Surgery, Yamaguchi University School of Medicine of Japan from January 2003 to February 2004 were enrolled in this study. Inclusive criteria： ① Multiple intervertebral levels of cervical spinal cord compression confirmed by MRI, e.g. 3 or more than 3 levels of compressin. ② Age ≥ 70 years old. ③ Numbness and sensory disturbance in the upper limbs and showed hyperreflexia in the lower limbs. Exclusive criteria： Patients with abnormal motor and sensory nerve conduction velocities in both upper and lower limbs were excluded. METHODS： Evoked spinal cord potentials （ESCPs） following transcranial electric stimulation （TCE-ESCPs）, epidural spinal cord stimulation （SpinaI-ESCPs） and median nerve stimulation （MN-ESCPs） were recorded in 23 patients from posterior epidural space intreoperatively. The abnormalities of TCE-ESCPs were defined as attenuation of amplitude of the D wave. The most cranial intervertebral level showing abnormal TCE-ESCPs with a marked reduction in size of the negative peak （reduction of over 50%） was considered as the upper level of the spinal cord lesion with respect to the corticospinal tract in white matter. The abnormalities of SpinaI-ESCPs were defined as marked reduction in the size of negative peak （reduction of over 50%）. The most caudal intervertebral level showing abnormal SpinaI-ESCPs was considered as the lower level of the spinal cord lesion with respect to the dorsal column pathway in white matter. The abnormalities of MN-ESCPs were defined as attenuation of the N13 amplitude,which was considered as the lesion level of the spinal cord with respect to the dorsal horn in gray matter. Radiological investigation： Lateral view of plain X-ray films was obtained in flexion and extension of the cervical spine. Instability of the cervical intervertebral level was determined as horizontal displacement of the vertebral body of over 3 mm. MAIN OUTCOME MEASURES ： The results of examination of TCE-ESCPs, SpinaI-ESCPs and MN-ESCPs in el- dedy patients with CSM. RESULTS： The 23 eldedy patients with CSM were participated in the result analysis. ①TCE-ESCPs： The impairment of the corticospinal tract in white matter at single intervertebral level was revealed in 18 of 23 patients by recordings of TCE-ESCPs （sensitivity 78%）. In the 18 patients, the lesion level was shown at the up- per cervical segment in 14 patients （C3-4n=10 and C4-5n=4）, and at the lower cervical segment in 4 patients （C5-6n=4）. ②Spinal-ESCPs： The impairment of the dorsal column pathway of white matter at single intervertebral level was revealed in 17 of 23 patients, by recordings of Spinal-ESCPs （sensitivity 74%）. In the 17 patients, the lesion level was presented at the upper cervical segment in 14 patients （C3-4n=10 and C4-5n=4）, and at the lower cervical segment in 3 patients （C5-6 n=3）. ③MN-ESCPs： All patients revealed abnormal MN-ESCPs at one or more intervertebral levels （sensitivity 100%）. The impairment at single intervertebral level was demonstrated in 17 patients, and the impairment at multiple intervertebral levels was shown in 4 patients （3 patients at the C3-4, C4-4, and C5-4~6, and one patient at the C4-5, C5-6, and C6-7）. ④Radiological findings： The Instability of the intervertebral level at the C3-4 or C4-5 motion segment was seen in 15 patients, with a total of 20 levels, and where 10 were at the C3-4 intervertebral level and 5 were at the C3-4, C4-5 intervertebral level. CONCLUSION ： The results suggest that in most elderly patients with CSM who have multiple intervertebral level compressions of the cervical spinal cord on MRI, white matter is impaired at the single cervical intervertebral level, and not only the dorsal column pathway, but also the corticospinal tract can be affected. Combined the findings of radiography, the excessive motion and instability of the C3-4 or C4-5 intervertebral level plays an important role in inducing the long tract lesion in elderly patients with CSM.

Spontaneous Cervical Epidural Hematomas in Mild Cervical Spondylotic Myelopathy Patients：An Analysis of 8 Cases

Spontaneous cervical epidural hematoms（SCEH） complicated with mild cervical spondylotic myelopathy（CSM） is a rare but emerging condition.Early diagnosis and treatment are important for good outcomes.This study aimed to investigate the clinical characteristics of this condition and to discuss the optimal treatment.The clinical data from 8 patients with SCEH plus CSM who were divided into two groups by treatment methods were retrospectively analyzed.The neurological function of the patients was assessed by Japanese Orthopedic Association（JOA） score before and after the surgical operations.Other factors were reviewed with medical records.Among them,4 out of the 8 patients underwent emergency surgery,and the rest 3 patients experienced an initial conservative treatment and ultimately received a laminectomy.We found that the Frankel Scale scores in most of the surgical patients were increased after surgery（6/7,85.7%）.However,the JOA scores at the 6th month after onset were even lower than those before onset in 3 of the operative cases,and those in the patients who were given conservative treatment showed no significant change.It was concluded that some patients with SCEH and CSM treated with a timely operation may obtain relief from their previous CSM symptoms.However,the final neurological deficits of these patients were closely related to the progressive interval which refers to the hours between the initial onset and the occurrence of new neurological deficits or mild CSM deterioration,no matter whether they accept the operation.We found the crucial progressive interval may be in 9 h.Early MRI and prompt neurosurgical intervention are also important to improve the neurological deficits.

Clinical Study of Acupotomy Trinity Lysis on Cervical Spondylotic Myelopathy with Liver and Kidney Deficiency Syndrome

Objective:To compare the therapeutic effects of acupotomy trinity lysis and traditional acupotomy on cervical spondylotic myelopathy.Methods:A total of 205 patients with cervical spondylotic myelopathy of liver and kidney deficiency syndrome were randomly divided into the experimental group(105 cases)and the control group(100 cases).The experimental group was relaxed with acupotomy in three positions:Heaven(tian),Human(ren)and Earth(di).Traditional acupotomy was used to relax Ashi acupoints of the affected vertebra in the control group.One treatment was conducted in one week,and the duration of one course of treatment was three weeks.The VAS,JOA score and NDI index were observed after treatment.Results:Before and after treatment,the total treatment efficiency of the treatment group was 95.23%,and that of the control group was 80.00%,there was significant difference between the two groups,P<0.05;Before operation,there was no significant difference in JOA score,NDI index score,and VAS score between the treatment group and the control group(P>0.05);there was no significant difference after 1 week(P>0.05),but there were significant differences between the two groups 2 weeks and 3 weeks after operation(P<0.05).Conclusion:Acupotomy trinity lysis is a safe,effective and economical treatment for cervical spondylotic myelopathy.

Curative Effects of Warming Needle Moxibustion Combined with Manipulation Massage on Cervical Spondylotic Vertebral Arteriopathy and Its Influence on the Cerebral Blood Flow Parameters and Cervical Vertebral Function

OBJECTIVE: To explore the curative effects of warming needle moxibustion combined with manipulation massage on cervical spondylotic vertebral arteriopathy and its influence on the cerebral blood flow and cervical vertebra function. METHODS: A total of 84 patients with cervical spondylotic vertebral arteriopathy admitted to our hospital from February 2016 to June 2017 were selected, and all patients were divided into an observation group (n=42) and a control group (n=42) according to the random number table method. The patients in the control group were given conventional western treatment, and the patients in the observation group were treated with warming needle moxibustion combined with manipulation massage on the basis of the control group. After 4 weeks of treatment, the changes of main clinical symptoms (vertigo, headache, neck and shoulder pain, tinnitus), cervical function (clinical symptoms, clinical examination, daily life action) and cerebral blood flow parameters (average blood flow velocity of left vertebral artery, right vertebral artery and basilar artery) of the 2 groups were observed, and the clinical efficacy of the 2 groups were statistically analyzed. RESULTS: The scores of vertigo, headache, neck and shoulder pain and tinnitus in the 2 groups were all significantly lower than before treatment (P < 0.05), and the clinical symptom scores in the observation group were significantly lower after treatment (P < 0.05);After treatment, the scores of clinical symptoms, clinical examination and daily life action in the 2 groups were significantly higher than those before treatment (P < 0.05), and the increase of cervical vertebral function score in the observation group was better than that in the control group (P < 0.05);The mean blood flow velocity of the left vertebral artery, right vertebral artery and the basilar artery in the 2 groups after treatment were significantly higher than before treatment (P < 0.05), and the increase of the above cerebral blood flow parameters in the observation group were higher than the control group (P < 0.05). The total effective rate was 92.9% in the observation group and 76.2% in the control group after treatment, and the difference between the 2 groups was statistically significant (P < 0.05). CONCLUSION: Warming needle moxibustion combined with manipulation massage can quickly relieve the clinical symptoms of patients with cervical spondylotic vertebral arteriopathy, improve the cervical function and cerebral blood flow parameters, increase the vertebrobasilar artery blood flow, and promote the recovery of the disease.

The VAS scores of the two groups after treatment were both improved （both P0.01）, but without statistic significance between the two groups （P0.05）. The numbness scores of the two groups after treatment were both better than those before treatment （P0.01）. The therapeutic effect on numbness of the extremities of the treatment group was better than that of the control group （P0.05）. Conclusion Blood-letting puncture with the plum flower needle has a satisfactory effect on treatment of numbness of the extremities of patient with cervical spondylotic radiculopathy.

Comparison of the anterior and posterior approach in treating four-level cervical spondylotic myelopathy

Background:The optimal surgical approach for four-level cervical spondylotic myelopathy remains controversial.The purpose of this study was to compare clinical and radiological outcomes and complications between the anterior and posterior approaches for four-level cervical spondylotic myelopathy.Methods:A total of 19 patients underwent anterior decompression and fusion and 25 patients underwent posterior laminoplasty and instrumentation in this study.Perioperative information,intraoperative blood loss,clinical and radiological outcomes,and complications were recorded.Japanese Orthopedic Association(JOA)score,36-item short form survey(SF-36)score and cervical alignment were assessed.Results:There were no significant differences in JOA scores between the anterior and posterior group preoperatively(11.6±1.6 vs.12.1±1.5),immediately postoperatively(14.4±1.1 vs.13.8±1.3),or at the last follow-up(14.6±1.0 vs.14.2±1.1)(P>0.05).The JOA scores significantly improved immediately postoperatively and at the last follow-up in both groups compared with their preoperative values.The recovery rate was significantly higher in the anterior group both immediately postoperatively and at the last follow-up.The SF-36 score was significantly higher in the anterior group at the last follow-up compared with the preoperative value(69.4 vs.61.7).Imaging revealed that there was no significant difference in the Cobb angle at C2-C7 between the two groups preoperatively(-2.0°±7.3°vs.-1.4°±7.5°).The Cobb angle significantly improved immediately postoperatively(12.3°±4.2°vs.9.2°±3.6°)and at the last follow-up(12.4°±3.5°vs.9.0°±2.6°)in both groups compared with their preoperative values(P=0.00).Three patients had temporary dysphagia in the anterior group and four patients had persistent axial symptoms in the posterior group.Conclusions:Both the anterior and posterior approaches were effective in treating four-level cervical spondylotic myelopathy in terms of neurological clinical outcomes and radiological features.However,the JOA score recovery rate and SF-36 score in the anterior group were significantly higher.Persistent axial pain could be a major concern when undertaking the posterior approach.

Efficacy of catgut-embedding therapy at"five neck points"on cervical spondylotic arteriopathy and effects on hemodynamics:A randomized clinical trial

Objective:To observe the effect of catgut-embedding therapy at five neck points in the treatment of cervical spondylotic arteriopathy(CSA)and analyze its effects on the hemodynamics of patients with CSA.Methods:Using the computer randomization method,72 patients with CSA were divided into a catgutembedding therapy group(n=36,none dropped out)and a western medication group(n=36,none dropped out).In the catgut-embedding therapy group,the therapy was applied to five neck points,i.e.bilateral Jǐngjiājǐ(颈夹脊)at C5,bilateral Jǐngjiājǐ(颈夹脊)at C6,and Dàzhuī(大椎GV14)once a week.One3-week treatment session was required.In the western medication group,flunarizine hydrochloride 5 mg capsules were administered orally once daily for 3 weeks.Efficacy was assessed before and after 3 weeks treatment using a functional evaluation scale for cervical spondylotic arteriopathy(FS-CSA).Changes in vertebral-basilar arterial hemodynamics,serum nitric oxide(NO)level,and plasma endothelin(ET)level were detected.Results:Efficacy was assessed when the treatment session was completed.The total efficacy rate was significantly higher in the catgut-embedding therapy group(86.1%)than in the western medication group(61.1%;P<0.01).The after treatment FS-CSA score was reduced compared with baseline score in both groups(P<0.05),and the reduction in the catgut-embedding therapy group was superior to that in the Western medication group(P<0.05).Compared with baseline,the flow velocity and pulsatility index of the bilateral vertebral and basilar arteries increased at each period in both groups(P<0.05)except for the left systolic velocity of the vertebral artery after treatment.The increase in the catgut-embedding therapy group was greater than that in the western medication group(P<0.05).After treatment,the serum NO concentration was increased and the plasma ET concentration was reduced compared to baseline in both groups(P<0.05),while the improvements in the catgut-embedding therapy group were superior to those in the western medication group(P<0.05).Conclusion:The clinical efficacy in the catgut-embedding therapy group was superior to that in the western medication group.Catgut-embedding therapy at five neck points may effectively improve psychological and functional conditions,promote vertebral basilar arterial supply,and relieve clinical symptoms in patients with CSA.
