Many neurological disorders can present similar symptomatology to degenerative cervical myelopathy (DCM) or myeloradiculopathy (DCMR). Therefore, to avoid misdiagnosis, it is important to recognise the differential diagnosis, which has been well described in previous literature. Additionally, DCM or DCMR can also coexist with other diseases that overlap some of its clinical manifestations, which may be overlooked before cervical surgery. Nevertheless, few studies have addressed this clinical situation. In clinical practice, the diagnosis of coexisting disease with DCM or DCMR would be typically made when some symptoms persist without improvement after cervical surgery. To inform the patients of this possibility preoperatively and arrive at the early diagnosis during the postoperative period, some knowledge of the possible coexisting diseases would be necessary. In this report, we reviewed 230 patients who underwent surgery for DCM or DCMR in an academic centre to examine the prevalence and kind of underlying disease that was overlooked preoperatively. The coexisting diseases relevant to their baseline symptoms were diagnosed only after cervical surgery in three patients (1.3%) and included amyotrophic lateral sclerosis, lung cancer and polymyalgia rheumatica. The overlapping symptoms were gait difficulty, scapular pain and neck pain, respectively. Surgeons should recognise that the coexisting disease with DCM or DCMR may be overlooked before cervical surgery because of overlapping symptomatology, although its prevalence is not certainly high. Further, when the specific symptom persisted without improvement after surgery for DCM or DCMR, the patient should be comprehensively examined, considering diverse pathological conditions, not only neurological disorders.  相似文献

目的 观察颈2棘突半棘肌止点保留基础上进一步改良单开门椎板成形术,观察手术疗效,探讨能否降低合并症。方法 重建改良组椎板成形术治疗脊髓型颈椎病45例,普通改良组39例,术后随诊18~24个月,对两组患者术前术后的颈椎活动度、日本骨科学会(Japanese Orthopedic Association Scoring System,JOA)评分及轴性症状严重程度进行比较评估。结果 两组颈椎活动度丢失(9.4°±4.1° vs 11.6°±7.8°)及JOA评分恢复率(57.7%vs 54.4%)比较,差异无统计学意义(P>0.05)。但比较两组术后轴性症状,其差异有统计学意义(P<0.05)。重建改良组发生率更低。结论 保留颈2棘突半棘肌止点的同时,重建颈4-7棘突能够进一步减小轴性症状的发生率。  相似文献

目的 探讨颈椎后路单开门椎管成形术(EOLP)不同椎板固定方法对颈椎曲度及轴性症状的影响.方法 回顾性分析天津市人民医院2009年1月至2012年1月因多节段脊髓型颈椎病(CSM)行EOLP的101例患者临床资料.其中32例采用传统缝线悬吊“门轴”(A组),35例患者采用锚钉法进行“门轴”固定(B组),34例患者采用微型钛板Centerpiece固定法(C组).对3组患者手术前、后日本骨科学会(JOA)评分,颈椎曲度变化及轴性症状评分进行分析.结果 3组患者平均随访时间为(31.83±5.10)个月,JOA评分改善率A、B、C组分别为(61.53±24.00)%、(60.72±19.82)%、(65.17±21.13)%,3组比较差异无统计学意义(F=0.41,P=0.67);颈椎曲度丢失A、B、C组分别为(3.38±1.51)%、(3.12±1.91)%、(2.24±1.30)%,3组比较差异有统计学意义(F=4.67,P=0.01);术后24个月轴性症状评分A、B、C组分别为(9.13±0.66)、(10.77±0.49)、(11.11±0.77)分,3组差异有统计学意义(F=88.30,P=0.00).JOA评分改善率与轴性症状评分无相关性(r=0.07,P>0.05),颈椎曲度丢失与轴性症状评分呈负相关(r=-0.21,P=0.03).结论 EOLP传统缝线悬吊“门轴”法、锚钉固定“门轴”法、微型钛板centerpiece固定法均是开门法“门轴”固定的有效方法,但微型钛板内固定法可有效地减少术后颈椎曲度的丢失,降低轴性症状的发生率.  相似文献

背景:有部分学者认为颈椎管狭窄症减压植入内固定后神经根麻痹与颈椎稳定性以及颈椎生理曲度有关,目前还存在争议。 目的:探讨颈椎管狭窄症后路全椎板减压侧块内固定与单开门减压椎管扩大成形治疗后C5神经根麻痹及稳定性。 方法:选取29例颈椎管狭窄症患者进行后路减压植入物内固定治疗。方法①:颈椎管狭窄症后路全椎板减压侧块内固定,在C3-6侧块以及C7椎弓根钉内固定,关节突关节处造成粗糙面。方法②:根椐治疗前对正侧位平片及动力位片结合MRI、CT影像学图片,明确不稳定的节段,给予相应节段侧块内固定、椎板行单开门减压,椎管扩大成形治疗。 结果与结论:29例颈椎管狭窄症患者随访8个月-2.3年,采用后路全椎板减压侧块内固定治疗的患者14例,植入后早期出现C5神经根麻痹2例,远期症状复发出现不全瘫3例,二次手术行瘢痕切除减压治疗;采用单开门减压椎管扩大成形治疗的患者15例,治疗后出现C5神经根麻痹肩外展功能不良1例,无治疗前症状复发病例。神经根麻痹最短6周,最长9个月均恢复。颈椎管狭窄症后路减压植入物内固定后,C5神经根麻痹与节段稳定性、颈椎生理曲度、椎管减压程度、脊髓漂移范围是否相关以及发生程度、远期因瘢痕致再度出现椎管狭窄,两种治疗方式的区别是否有意义,目前病例数有限,有待病例及临床经验的积累与观察。  相似文献

ObjectiveThis study is to introduce lift‐open laminoplasty and verify the increase of the spinal canal area following this surgical technique according to the preoperative anatomical measurement.MethodsThere are 82 patients (43 male and 39 female) analyzed in our study from January 2019 to December 2020. The average age was 63.2 ± 3.21 years (from 41 to 84 years). All of them were treated with open‐door laminoplasty, with a decompression segment range from C3 to C6. The increase of the spinal canal area after open‐door laminoplasty was measured on postoperative CT images of the patients, and the distances between both lamina‐facet junctions and lamina length was measured on preoperative CT images. Using the Pythagorean theorem for the equation of calculation area after the expansile open‐door laminoplasty. Based on previous measurement parameters, spinous process length, lateral mass width, distance between osteotomy line and lamina‐facet junctions line were additionally measured on preoperative CT images. Pythagorean theorem was used for calculating the area after the expansile lift‐open laminoplasty. The results were recorded and a statistical analysis was undertaken. Then, there were six patients (five male and one female) treated with lift‐open laminoplasty on C6, open‐door on C3–C5, who suffer from cervical spondylotic myelopathy from December 2020 to January 2021. The average age was 60.3 ± 1.7 years (from 56 to 71 years). Operation time, blood loss, and Japanese Orthopaedic Association (JOA) score recovery rate were recorded. Intraoperative and postoperative complications were observed.ResultsThe increase of the spinal canal area after open‐door laminoplasty measured on postoperative CT images was 123.01 ± 17.06 mm2 and the calculation of the increase of the spinal canal areausing the Pythagorean theorem after open‐door laminoplasty was 122.86 ± 15.86 mm2. A comparison of the actual value with calculative value showed no significant difference (T value = 0.057, P value = 0.955). The calculation of the increase of the spinal canal area after lift‐open laminoplasty was 183.57 ± 62.99 mm2, which was larger than that after open‐door laminoplasty (T value = 8.462, P value < 0.001). Mean operation time was 153.3 min and operative blood loss was 600 mL of the six patients treated with lift‐open laminoplasty. At 1 month follow‐up, all patients had recovered well. JOA score recovery rate was 37.6% and no intraoperative and postoperative complications occurred.ConclusionLift‐open laminoplasty could preserve nearly 100% of extensor muscle, avoid damaging C7 paraspinal muscles and C6‐7 posterior muscle‐ligament complex, reconstruct the spinous process firmly in the midline, and expand adequate spinal canal area after operation. These advantages could reduce the incidence rate of complications and bring better clinical results than traditional laminoplasty.  相似文献
