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。

MED治疗腰椎间盘突出症时对神经根变异的探查

目的：观察显微内窥镜下椎间盘切除术（microendoscopic discectomy，MED）治疗腰椎间盘突出症时神经根变异情况，防止出现术中神经根损伤。方法：回顾分析自1999年10月至2003年12月应用MED治疗的腰椎间盘突出症患者724例，其中男452例，女272例。对术中发现存在腰骶神经根变异患者的临床特点及术中所见进行统计分析。结果：724例腰椎间盘突出症患者有37例神经根变异，发生率为5.1％。与术前的临床表现吻合，全部神经根变异患者均在MED下完成手术，无一例出现神经根损伤。结论：仔细探查及分离突出髓核周围神经根发出情况．确定有无神经根变异是防止MED治疗腰椎间盘突出症时发生神经根损伤的重要环节之一。     

椎管扩大成形术治疗腰椎管狭窄

目的：探讨椎管扩大成形术治疗腰椎管狭窄的效果。方法：椎板减压后复位，用棘突或髂骨植于一侧开槽处扩大椎管，并进行椎板及关节突关节植骨，对54例随访病人的手术前后临床表现及X线和CT进行比较。结果：随访6—39个月，临床优良率为81．1％。随访X线片显示椎板明显后移，CT测量与术前对比显示椎管内径扩大明显。结论：椎管扩大成形术操作简单，效果满意，术后并发症少，是治疗腰椎管狭窄的又一选择。     

腰椎穿刺术后头痛与卧床时间的关系

目的探讨腰椎穿刺术后平卧时间30min、2h对头痛的影响。方法对794例具有腰椎穿刺术适应证而无禁忌证并排除有关因素的患者，随机分为30min组、2h组。分别观察术后头痛发生率。结果30min组头痛发生率为（8／460）1．74％，2h组为（7／334）2.10％，两组组间比较均无显著性差异（P〉0．05）。结论本研究说明腰穿后卧床时间长短（30min～2h），对腰穿后头痛的发生率无影响，可缩短至30min，没有必要卧床2h，更没有必要卧床4～6h。     

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.     

腰椎融合术后邻近节段退变的诊断与治疗

目的：探讨腰椎融合术后邻近节段退变的特点及再手术治疗的术式与疗效.方法：回顾性分析2002年1月至2004年12月间收治的10例因腰椎管狭窄症或腰椎滑脱症曾行后路减压、植骨及椎弓根内固定术,术后12～132个月（平均41.6个月）出现新的腰腿痛症状的病例.对所有患者进行影像学检查,与术前资料比较,并行手术治疗.结果：X线片显示融合的上方（1个节段7例,2个节段1例）或下方（1个节段2例）邻近节段出现了退变,首次术前及术后上述邻近节段均未见退变征象.8例MRI显示邻近节段出现了新的椎管狭窄,且有明显的神经压迫.采用后路术式,将减压及固定融合范围向邻近退变节段延伸.经7～36个月平均12.1个月的随访,优良率80%.结论：腰椎融合术后邻近节段退变是术后症状复发的原因之一,应仔细鉴别症状复发的原因.对于有明显神经压迫者,再手术治疗仍可取得较好的疗效.     

腰椎终板、椎间盘退变及椎间盘造影疼痛激发试验的相关性研究

目的探讨下腰痛患者腰椎终板Modic退变、椎间盘退变及CT引导下腰椎间盘造影疼痛激发试验的相关性.方法对45例下腰痛患者常规行腰椎X线和MR检查,分别按Modic终板退变标准（0～3级）与Pearce椎间盘退变标准（Ⅰ～Ⅴ级）对终板和椎间盘进行评估.在CT引导下对45例患者中的40例（120个椎间盘）进行造影和疼痛激发试验,并按Dallas椎间盘造影分级系统（DDD）测评椎间盘退变程度.采用SPSS 11.5统计学软件分析腰椎终板Modic退变、椎间盘退变与腰椎间盘造影疼痛激发试验之间的相关性.结果40例下腰痛患者的腰椎终板Modic分级与椎间盘退变Pearce分级存在较强的相关性（Pearson x^2=43.326,P=0.000）,与椎间盘造影疼痛激发试验有显著相关性（Pearson x^2=27.858,P=0.000）;椎间盘退变Pearce分级与CT椎间盘造影椎间盘退变Dallas分级也呈较强的相关性.结论腰椎终板Modic退变分级与椎间盘退变Pearce分级密切相关,而与椎间盘疼痛激发试验有显著相关性,提示终板Modic退变可能是下腰痛的原因之一.     

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.
