极外侧腰椎间盘突出症的临床分型及手术方式选择

Objectives To suggest the clinical classification of the far-lateral lumbar disc herniation and offer the considerations for clinical choice of different surgical procedures. Methods According to the locations of the herniated disc and relevant clinical symptoms, the far-lateral lumbar disc herniation was divided into three types: Type Ⅰ: posterolateral and foraminal herniation (double herniations); Type Ⅱ: foraminal disc herniation and Type Ⅲ: extraforaminal herniation. From January 2002 to January 2007, 38 patients with far lateral lumbar disc herniation underwent surgery in the institute. The surgical options were decided by means of the classificasion. The surgical procedures included (1) discectomy by inter-TP (transverse process) approach, (2) discectomy with partial facetectomy and (3) discetomy with facetectomy and PLIF (posterior lumbar interbody fusion). Among the 38 patients, there were 25 males and 13 females. The mean age was 58.4 years old. The herniated discs located at L3-4 in 17, L4-5 in 13, and 8 cases at L5S1. Twenty-three patients were simple disc herniation, 15 cases with concomitant lumbar spinal stenosis. The symptoms and signs of exiting root compression at herniated disc level were presented in all patients and passing root compression presented in 7 Type Ⅰ cases as well; while intermittent claudication being presented in 15 and low back pain in 21 patients. The VAS (visual analog pain scale) of radicular leg pain was taken before and after the operation. The postoperative outcomes were evaluated through the MacNab's method in all the patients. Results By using the new classification system, the 38 patient were divided into Type Ⅰ 10 cases, Type Ⅱ 19 cases and Type Ⅲ 9 cases. The adopted surgeries included discectomy by intertransverse approach in 5, discectomy with partial facetectomy in 7, and discetomy with facetectomy and PLIF in the rest 26 eases. The mean follow-up period was ranging from 6 months to 4 years and 10 months, averagely 2 years and 11 months. The mean VAS scores of radicular pain was 7.4 preoperatively, 2. 7 at 2 weeks after the operation and 3. 1 at final follow-up. The final clinical outcomes by MacNab's method were as follow: excellent results in 20 cases, good in 12, fair in 5 and poor in 1 case. The overall improvement ratio was 84. 2%. The postoperative complications included superficial wound infection in 1 case, insufficient decompression in 1 case and leakage of cerebrospinal fluid in 1 case respectively. No breakage and loosening of internal fixation were detected. Conclusions A new clinical classification of far lateral lumbar disc herniation was suggested, which is significant to understanding the relevant pathology and choosing the surgical procedures.

Objective To investigate retrospectively the long-term results of discectomy for patients with lumbar intervertebral disc herniation. Methods From July 1988 to May 2003, 273 cases of 1040 patients with lumbar intervertebral disc herniation undergone surgical treatment in our hospital were followed up. All patients were divided three groups according the time of follow-up. The follow-up time was three years as middle follow-up group (Ⅰ), five years as longer follow-up group(Ⅱ) and ten years and more as sup-longer follow-up group (Ⅲ). Sixty-eight cases(24.91%) were in group Ⅰ, including 42 males and 26 females, with the average age of 43.7 years (14-63 years). The group Ⅱ included 141 cases (51.65%), 92 males and 49 females, with the average age of 46.1 years (18-76 years). As group ⅡⅢ, 64 cases (23.44%) were included 46 males and 18 females, with the average age of 43.5 years (20-63 years). The standards Scoring System of Chinese Spinal Association (CSA) and Japan Orthopaedic Association (JOA) were used for investigation. Results According to CSA system, the total good and excellent rate of surgical treatment for lumbar intervertebral disc herniation was 89.0%. The percentage of the satisfactory of the group Ⅰ, Ⅱ, Ⅲ were 92.6%, 91.5% and 79.7% respectively. There was significant difference between group Ⅰ and group Ⅱ, Ⅲ. The score of JOA were 24.75±5.08, 22.43±6.55, 21.64±7.18 postoperatively, with significant difference between group Ⅰ and group Ⅱ, Ⅲ. Conclusion The mid-term results of surgery for patients with lumbar iutervertebral disc herniation is good, and the good and excellent rate decreases gradually with the follow-up time. The results were similar to each other for evaluation between the standard of CSA and JOA.

目的观察经椎间孔融合(transforaminal lumbar interbody fusion,TLIF)联合单侧椎弓根钉内固定治疗高位腰椎椎间盘突出症的临床疗效。方法 2006年3月～2008年12月收治且获得随访的单间隙高位腰椎椎间盘突出症患者23例,其中L1/L25例,L2/L38例,L3/L410例。均采用经椎间孔单枚Cage植骨融合并单侧椎弓根螺钉内固定术治疗。根据日本骨科学会(Japanese Orthopaedic Association,JOA)(29分)评分法评估术后疗效,计算改善率和优良率,观察植骨融合情况。结果 1例硬脊膜撕裂,1例椎弓根螺钉位置偏斜。随访23～52个月,平均40.2个月,JOA评分由术前10.04±2.12提高到随访23个月时的24.13±3.39,优良率为91.3%。23个月时骨性融合率为95.8%。结论TLIF联合单侧椎弓根钉内固定治疗高位腰椎椎间盘突出症具有不破坏健侧结构,手术和住院时间短,内固定费用低,神经功能康复好的优点,是治疗高位腰椎椎间盘突出症可供选择的较好方法。     

腰椎间盘突出症术后原间隙再突出的病因分析和策略

目的回顾性分析临床确诊为腰椎间盘突出症并行单纯髓核摘除手术治疗证实的患者,术后2年内出现原手术间隙髓核再突出的临床资料,为一期手术时减少腰椎间盘手术失败综合症的发生提供参考。方法分析1995~2005年我科收治的患腰椎间盘突出症并行单纯髓核摘除的患者中,术后2年内发生原间隙髓核再突出的63例患者的临床表现,以及该患者第1次手术时的临床资料及手术方式。其中男41例,女22例。初次手术在我科进行的9例,于外院进行的54例。行椎间盘镜及小开窗手术者21例,半椎板及全椎板手术者42例。单间隙手术者51例,2个间隙及以上者12例。结果17例患者再次手术时仍采用单纯髓核摘除治愈,41例患者行后路椎管减压髓核摘除椎弓根螺丝钉内固定植骨融合术(PLIF),5例患者行经椎间孔髓核摘除椎弓根螺丝钉内固定植骨融合术(TLIF)。所有病例均于二次手术后治愈。结论腰椎间盘突出症手术后再突出是一临床常见的难题,不论早期和晚期均有可能发生,合理选择手术适应症及恰当的手术方式有利于减少再突出的发生,二次手术可获得临床治愈。     

复发性腰椎间盘突出症两种手术方式对比分析

[目的]分析复发性腰椎间盘突出症的病理机制及探讨椎间融合器后路椎间融合内固定治疗的理论依据及优缺点.[方法]将24例有明显腰椎不稳表现的复发性腰椎间盘突出症患者分为内固定组(14例)和非内固定组(10例),分别采用椎间融合器后路椎间融合内固定治疗和重复的髓核摘除术治疗,对临床资料进行总结.[结果]2组病例均获6个月以上,平均18个月的随访,内固定组14例无机械不稳引起的并发症如椎体滑脱,无椎间融合器后退及下沉,无螺钉断裂及松动;根据MacNab疗效评定标准,优良率92.8%.非内固定组10例腰椎不稳仍存在或加重,3例发生腰椎滑脱;根据MacNab疗效评定标准,优良率60%.[结论]复发性腰椎间盘突出症病理机制主要是腰椎不稳,椎间融合器后路椎间融合内固定治疗符合生物力学要求,疗效确切.     

腰椎间盘突出症合并足下垂的外科治疗

目的：探讨腰椎间盘突出症合并足下垂的临床特点和外科治疗效果。方法：回顾分析我科1995年至2004年期间治疗的34例腰椎间盘突出症合并足下垂患者的临床资料，合并足下垂患者占同期同期收治腰椎间盘突出症1545例的2．2％。均行手术治疗，其中20例采用半椎板切除突出椎间盘摘除术，8例采用全椎板切除突出椎间盘摘除术，4例行间盘切除，椎弓根钉内固定，后外侧植骨融合术，另2例行内窥镜下病变节段椎间盘切除术。所有患者围手术期均辅以静脉滴注甲基强的松龙治疗。结果：术中可见受压神经根均有不同程度增粗，无并发症发生。术后随访3个月至5年，平均38个月，无复发病例。按患足背伸肌力较术前恢复程度评定，疗效优18例，良12例，可2例，无恢复2例。结论：腰椎间盘突出症合并足下垂患者选择合理的手术方式，围手术期应用甲基强的松龙，治疗效果较好。
