目的探讨腰椎间盘突出症导致非对称性下肢放射痛的可能原因及术式的选择。方法25例经SCT、MRI检查证实为突出侧与临床症状侧别左右不一致的腰椎间盘突出症患者,均行手术治疗,其中14例行双侧开窗减压探查髓核摘除术,11例仅行突出侧开窗术。结果影像学上髓核突出侧别与术中所见相吻合,但该侧神经根未见到明显压迫或炎性水肿等病理表现;而症状侧无髓核突出,5例神经根未发现异常表现,9例存在不同程度的炎性水肿,其中6例探查发现神经根与对侧髓核不同程度粘连。术后所有患者症状均得到缓解,经过1~5年(平均2.4年)的随访,均无复发。结论SCT结合MRI检查有助于此类腰椎间盘突出症的明确诊断。纤维环无破裂的突出型腰椎间盘突出症,单纯突出侧减压可以获得较好的治疗效果;纤维环破裂的游离型及脱出型腰椎间盘突出症,宜同时行对侧开窗探查。 相似文献

目前国内外对腰椎间盘突出症的各种手术和非手术方法甚多,意见也不一致,但是多数学者认为破裂型腰椎间盘突出症宜早期手术治疗,反复非手术治疗可延误诊治,甚至出现严重并发症。因此,能正确诊断破裂型腰椎间盘突出症对指导治疗有重要意义,本文就近年来对该病的诊断作一综述。 一、临床表现 腰椎间盘突出症临床表现复杂,一般仅根据病史和体征往往难以对破裂型腰椎间盘突出症确诊[1],破裂型腰椎间盘突出症,系指腰椎间盘纤维环完全破裂或破碎,并同髓核甚至软骨板脱出于纤维环外,但未完全游离椎管内[2],可分为脱出后纵韧带下… 相似文献

腰椎间盘突出症手术疗效与突出类型及纤维环完整性的关系 总被引:42,自引:0,他引:42
目的探讨腰椎间盘突出症手术疗效与突出类型及纤维环完整性的关系。方法回顾性分析经后路椎板开窗髓核摘除术治疗的260例腰椎间盘突出症患者的疗效。病例选择条件:均为下腰椎单节段突出,侧突型(单侧坐骨神经症状),不伴有椎管狭窄。随访6~14年,平均8.5年。根据术中所见椎间盘突出的髓核形态及纤维环破损大小,将椎间盘突出症分为四种类型,并对不同类型的术后疗效进行统计学分析比较。结果椎间盘髓核突出较大、纤维环破损较小者,术后疗效佳,复发率低;反之,髓核突出较小或纤维环破损大者,术后疗效差,复发率高。结论腰椎间盘突出症的手术效果与椎间盘突出类型及纤维环的完整性有密切的联系。对临床症状较轻、间盘突出较小且突出物基底较宽的患者应尽量避免开放式手术。椎间盘突出摘除术中除应注意保持脊柱骨性结构的稳定性,还应尽量避免过多地破坏椎间盘纤维环的完整性。 相似文献

Computer-assisted simulation of C4-C5, C5-C6, and C6-C7 intervertebral disc space narrowing was performed on 16 anatomic specimen cervical spines to determine the relationship of the cross sectional foraminal areas with the degree of narrowing of the cervical intervertebral disc space. Compared with normal foraminal area values, reduction of 20% to 30% of the foraminal area was found after 1 mm narrowing of the intervertebral disc spaces; reduction of 30% to 40% of the foraminal area was found after 2 mm narrowing of the intervertebral disc space; and reduction of 35% to 45% of the foraminal area was found after 3 mm narrowing of the intervertebral disc space. Statistically significant differences were found among the remaining cross sectional foraminal areas after different degrees of intervertebral disc space narrowing. Compression of the nerve root within the intervertebral foramina after the collapse of the intervertebral disc space cannot be ignored, and an appropriate surgical procedure to maintain the normal height of the disc space is essential. The size of the intervertebral foramen is related directly to the height of the intervertebral disc space. A 3-mm vertical reduction of the intervertebral disc space is associated more frequently with severe narrowing of the neuroforamen. 相似文献

腰椎融合术是治疗下腰椎疾患的一种有效方法。由于既要考虑减少后柱结构的破坏和硬膜外疤痕形成,又要保证植骨床良好的准备和前柱支撑。骨科医生在手术过程中常常顾此失彼。近年来,LoweandTaharnia[1] 报道经单侧椎间孔径路显露椎间隙,使用多种椎间隙撑开方法显露术野,植入钛网融合器来完成椎体间融合(unilateraltransforaminallumbarinterbodyfusion ,简称TLIF技术)。我院自2 0 0 2年底开展此技术,治疗3例下腰椎疾患。报告如下。1 临床资料本组男1例,女2例。年龄39~5 5岁,平均4 6 .4岁。病变间隙均为L4 ,5节段,2例为腰椎间盘突出并侧… 相似文献

Postoperative intervertebral discitis 总被引:9,自引:0,他引:9
Discitis is a rare complication of disc operation. During a 10-year-period 1100 patients were operated for lumbar disc herniation and only eight patients developed postoperative discitis. The symptoms began 3 weeks after the operation and the most prominent clinical feature was back pain with muscle spasm. The sedimentation rate was highly elevated but the body temperature was slightly elevated for only a few days. Typical radio-graphic findings were narrowing of the affected disc space and end-plate resorption 3-4 weeks after the initial symptoms. In the early phase, CT showed hypodense disc material in the affected disc space, which may be the first radiological sign of discitis. 相似文献

腰椎间盘突出与有无临床症状的影像对照研究 总被引:1,自引:1,他引:1
目的:探讨应用区域定位评分法研究腰椎间盘突出(膨出、突出、脱出)有临床症状与无临床症状的相关性及原因分析。方法:将符合要求的CT病理分型为膨出、突出、脱出的体检或住院或门诊患者120例,按有临床症状与无临床症状分为2组,每组按CT病理分型分3组,年龄20-59岁,平均38.5岁,有临床症状与无临床症状两组间在性别、年龄、病程及椎间盘分布节段差异均无统计学意义;应用区域定位评分法对各组评分;用游标卡尺分别测量矢状径指数(SI)、盘黄韧带前间隙、侧隐窝上口宽度、硬膜囊前后径。CT值由X线断层扫描测定,分别测量3次,取平均值。结果:④腰椎间盘突出有临床症状与无临床症状两组在SI、CT值、CT评分、硬膜囊前后径之间差异无统计学意义(P〉0.05);在侧隐窝上口宽度、盘黄韧带前间隙之间差异有统计学意义(P〈0.05)。②腰椎间盘突出有临床症状与无临床症状两组突出类型比较,差异有统计学意义(P〈0.05);腰椎间盘脱出有临床症状与无临床症状两组突出节段比较,差异有统计学意义(P〈0.05)。结论:①腰椎间盘突出大小、部位、类型不一定与临床症状存在必然关系,腰椎间盘突出症与压迫程度无正比关系;②椎管内突出髓核是否导致相应的临床症状存在着诸多或必然因素,可能与椎间盘突出物可代偿的椎管储备容量、受累神经根对机械压迫的逃逸避让与弹性延长功能,以及受累神经根低氧消耗与抗缺血性损伤代偿作用等因素有关。 相似文献

Degenerative changes in the material properties of nucleus pulposus and anulus fibrosus promote changes in viscoelastic properties of the whole disc. Volume, pressure and hydration loss in the nucleus pulposus, disk height decreases and fissures in the anulus fibrosus, are some of the signs of the degenerative cascade that advances with age and affect, among others, spinal function and its stability. Much remains to be learned about how these changes affect the function of the motion segment and relate to symptoms such as low back pain and altered spinal biomechanics. 相似文献
