针刀配合针灸治疗腰椎间盘突出症的临床疗效观察

目的:分析针刀与针灸配合应用于腰椎间盘突出症患者中的临床治疗效果。方法:在我院针灸康复科2017年12月-2018年12月治疗的腰椎间盘突出症患者中选取64例,并严格按照系统随机分配原则分为对照组和观察组,各32例。其中对照组采用针灸进行治疗,观察组采用针刀与针灸配合治疗,观察对比两组患者治疗后临床效果和治疗前后运动功能评分(Fugl-Meyer)、腰椎日本骨科学会(Japanese Orthopaedic Association,JOA)评分、视觉模拟评分法(Visual Analogue Scale,VAS)评分以及临床症状改善情况。结果:两组患者治疗前Fugl-Meyer、VAS、JOA评分差异无统计学意义(P>0.05),治疗后对照组VAS评分高于观察组,Fugl-Meyer、JOA评分低于观察组,且对照组总有效率低于观察组,对照组腰骶疼痛评分和腿疼痛评分均低于观察组,直腿抬高度高于观察组,差异具有统计学意义(P<0.05)。结论:予以腰椎间盘突出症患者针刀与针灸配合治疗效果显著,效果优于单一使用针灸治疗,可有效缓解患者疼痛感,改善临床症状,值得推广。     

腰椎间盘突出症疗效不佳的临床观察

目的 分析腰椎间盘突出症手术疗效不佳的原因，探讨提高疗效的方法。方法 随访本院1993-2003年腰椎间盘突出症行后路髓核摘除术病例236例，对术后腰腿痛症状未缓解或症状消失后再复发者复查X片、CT或MRI了解病因。结果手术疗效不佳者25例。疗效不佳的主要原因为残留髓核再突出、术后脊柱不稳倾向增加、对侧隐窝狭窄认识不足、神经根损伤、极外侧型椎问盘突出漏切、感染、术后椎管内瘢痕黏连等。全椎板切除术较椎板问开窗术更易发生椎管内瘢痕黏连（P＜0．01）。结论首次手术时应尽可能取净髓核组织，对动力位摄片发现有椎问不稳倾向者行后外侧植骨或椎体问植骨融合，常规探查并妥善处理侧隐窝，牵拉神经根时间不应过长且用力轻柔。行腰椎间盘CT和MRI扫描时，应注意包括椎间盘相邻上下椎体的1／3部，以防止遗漏极外侧型椎问盘突出，尽量采用椎板间开窗术式以减少脊柱创伤，术中间断冲洗，术毕持续负压引流，以减少术后黏连，术中应严格无菌操作。     

脊椎转移瘤增强减影MR成像

目的评估增强减影在脊椎转移瘤MR I中的应用价值。方法50例脊椎转移瘤病人进行MR I增强扫描,对比剂采用Gd-DTPA(0.1 mmol/kg),然后用T1W I增强后的图像与增强前的图像进行减影。通过对比噪声比(CNR)、信噪比(SNR)以及肿瘤边界清晰程度的比较,对MR I减影与否进行评估。结果MR I对比增强减影图像比传统的T1W I增强图像显示更清晰、更直观。所有脊椎转移瘤图像MR I减影的CNR和SNR比常规T1W I增强图像的CNR和SNR高。MR I减影CNR为155.05±24.73(x±SD),常规T1W I增强图像的CNR为11.11±14.26(t=35.65,Ρ<0.001)。MR I减影SNR为192.82±32.89(x±SD),常规T1W I增强图像的SNR为46.03±28.22(t=23.95,Ρ<0.001))。MR I对比增强减影图像比传统的T1W I增强图像能更好地显示脊椎转移瘤的边界和侵犯情况(2χ=29.34,Ρ<0.005)。结论MR I增强减影为探查和评估脊椎转移瘤提供了一个新的诊断方法。

Detailed pathological changes of human lumbar facet joints L1–L5 in elderly individuals

Facet joints play an important role in intervertebral load transmission and are crucial for rotational kinematics. Clinically, the role of facet joints as a possible source of low back pain is seen as controversial and at present is not sufficiently investigated. In this study, human lumbar facet (zygapopyhysial) joints from donors with advanced age were analyzed macroscopically, for degenerative changes. The aim was to determine the extent and morphology of degenerative changes in these joints. Lumbar facet joints (L1–L5) of 32 donors were studied (mean age 80.1±11.2 years). Joint capsules were carefully removed and joint surfaces (5 zones) examined using magnifying glasses and probes. In the result, the majority of facet joints showed cartilage defects of varying extent. Defects were located mostly at the margins of the articular surface, the central zone being relatively well preserved. Defect localization was different between superior (most cartilage defects in superior zone) and inferior (most defects inferiorly) facets. Further, defects were more severe caudal (level of L5) and in older persons. Osteophytes were present in up to 30%, located mostly at the latero-dorsal enthesis of the joint capsule on the superior facet. In conclusion, most margins of the articular facets are subject to degenerative changes in the lumbar spine of elderly persons, the topographical pattern being different in superior and inferior facets. This observation can be explained by the segmental motion patterns during extension/flexion movements of the facets. Sometimes, due to the marginal extension, it is obvious that not all changes can be assessed by CT or MRI.     

The value of a pantaloon cast test in surgical decision making for chronic low back pain patients: a systematic review of the literature supplemented with a prospective cohort study

The results of lumbar fusion in chronic low back pain (LBP) patients vary considerably, and there is a need for proper patient selection. Lumbosacral orthoses have been widely used to predict outcome, however, with little scientific support. The aim of the present study was to determine the value of a pantaloon cast test in selecting chronic LBP patients for lumbar fusion or conservative management. First, a systematic review of the literature was carried out in which two independent reviewers identified studies in Medline, Cochrane and Current Contents databases. Three papers met the selection criteria. In the only study with a control group, a significantly better outcome after fusion compared to conservative treatment was found in patients who reported significant pain relief while in a cast (i.e. a positive cast test). The results of lumbar fusion, however, were not significantly different for patients with a positive and those with a negative cast test. In addition to the review, a clinical cohort study of 257 LBP patients, who had been allocated to either lumbar fusion or conservative management by a temporary external transpedicular fixation trial, was performed. Prior to allocation, all had undergone a pantaloon cast test. Patients with no history of prior spine surgery and with a positive pantaloon cast test had a better outcome after lumbar fusion than those treated conservatively (P = 0.002, χ ² test). In patients with previous spine operations the outcomes were poor and the test was of no value. From the literature and the present patient cohort, it was concluded that only in chronic LBP patients without prior spine surgery, a pantaloon cast test with substantial pain relief suggests a favorable outcome of lumbar fusion compared to conservative management. The test has no value in patients who have had previous spine surgery.     

Sciatic Neuropathy: Case Report and Discussion of the Literature on Postoperative Sciatic Neuropathy and Sciatic Nerve Tumors

Sciatic nerve injury and dysfunction is not an uncommon cause of lower extremity symptoms in a musculoskeletal practice. We present the case of a man who presented with lower extremity weakness, pain, and cramps, and was initially diagnosed at an outside institution with bilateral S1 radiculopathies and recommended for spine surgery. He came to us for a second opinion. Electrodiagnostic testing revealed an isolated sciatic neuropathy and the patient was referred for imaging, which showed a sciatic nerve sheath tumor. Review of the literature on sciatic neuropathies shows that there can be many possible etiologies of sciatic nerve dysfunction, but that hip arthroplasty continues to be the leading risk factor. Sciatic nerve tumors are not commonly described in the literature and their definitive management remains unclear.
