Long-term changes in the magnetic resonance image after chemonucleolysis

Summary After treatment of a symptomatic herniated disc with chymopapain, 14 patients were re-examined by magnetic resonance imaging (MRI) at a mean follow-up of 72 months. Well-defined MRI findings before chemonucleolysis were compared with those after the procedure by an independent observer. Five MRI parameters were assessed. No significant change was noted in the signal intensity of the affected disc, the extent of osteochondrosis and endplate reaction of the affected segment. The height of the affected disc as well as the size of the disc herniation were reduced significantly. The loss of the height is seen as a direct result of chymopapain activity, whereas the alteration of the size of the herniation seems to depend on the natural history of a disc herniation and is probably not a simple result of the treatment.     

腰椎间盘突出症三种治疗方法的回顾性研究

目的 :对后路显微内窥镜下髓核摘除术 (MED组 )、后路开窗髓核摘除术 (Love组 )及胶原酶化学溶盘术 (CCNL组 )治疗腰椎间盘突出症的方法和疗效进行回顾性研究。方法 :采用统一的病例选择和疗效评定标准 ,对 2 37例患者 (其中MED组 87例 ,Love组 6 5例 ,CCNL组 85例 )进行分析 ,比较三组术后近、中期日本骨科协会 (JOA) 2 9分法评分及优良率 ,同时比较MED组和Love组病人围手术期有关情况。结果 :(1)MED组术后近、中期JOA评分及优良率高于Love组 ,但无统计学差异 ;(2 )CCNL组近、中期JOA评分及优良率均低于MED和Love组 ,差异显著 (P <0 .0 0 1) ;(3)术后中期与近期JOA评分比较 ,MED组和Love组有所提高 (P <0 .0 0 1) ,而CCNL组则略有下降 (P >0 .0 5 ) ;(4 )MED组在手术切口长度、术中出血量、术后引流量和卧床时间等方面均优于Love组 (P <0 .0 0 1)。结论 :在治疗腰椎间盘突出症的三种方法中 ,MED手术较Love法创伤更小 ,恢复更快 ,较CCNL术疗效更好。但CCNL术也有方法简单方便 ,基本无创的优点。     

椎间盘突出症不同治疗方法回顾性分析

目的分析臭氧髓核消溶术（A组）、后路开窗髓核摘除术（B组）以及胶原酶化学髓核消溶术（C组）治疗椎间盘突出症的方法和后期效果。方法采用统一的病例选择和疗效标准,对185例患者（其中A组60例,B组63例,C组62例）进行分析,比较3组治疗后评分和优良率。结果A组治疗后评分和优良率明显高于B组和C组,有非常显著性差异（P〈0.01）,B组高于C组有显著性差异（P〈0.05）。结论椎间盘突出症不同治疗方法中,臭氧髓核消溶术和胶原酶化学髓核消溶术明显优于开窗髓核摘除术,具有基本无创的优点。而开窗髓核摘除术相对而言创伤较大,对脊柱的稳定性有一定的影响。臭氧髓核消溶术是椎间盘突出症治疗方法中最理想的方法。

Experimental studies on the effects of recombinant human matrix metalloproteinases on herniated disc tissues--how to facilitate the natural resorption process of herniated discs.

PURPOSE: Recently, MMP-7 and MMP-3 have been found to play a crucial role in the natural resorption process of herniated discs. We therefore examined the role of these recombinant human matrix metalloproteinases (rh MMPs) in the treatment of herniated discs. METHODS: (a) Surgical samples of herniated disc were cultured in the presence or absence of rh MMPs, and wet weight was measured 24h later. (b) The rh MMPs were administered into normal rabbit intervertebral discs, and after 1 week spine samples were stained with Safranin O. (c) The rh MMPs were administered into canine herniated discs in vivo. Myelography and MRI were performed prior to and 1 week after administration. Spine samples were examined histologically. Whole disc tissue was collected, total protein was extracted, and Western blot analysis was performed. RESULTS: (a) Proteoglycan degradation was found in MMP-7, MMP-3, and chymopapain-treated samples. MMP-7 and chymopapain-treated samples displayed a significant loss in wet weight (p<0.01). (b) Normal disc tissues after administration of rh MMP-7, MMP-3, and chymopapain showed an extensive loss of Safranin O staining. (c) The rh MMP-7-treated discs had a marked decrease in protruded herniation by MRI. Herniated discs after administration of MMP-7 and chymopapain showed a significant decrease in protruded mass 7 days after administration compared with saline-treated discs when evaluated by myelography (p<0.01). The rh MMP-7-treated discs displayed a clear loss of Safranin O staining in the nucleus pulposus. Proteoglycan expression was barely detectable in disc tissues after MMP-7 administration, whereas obvious expression was obtained in saline-treated or untreated disc tissues. CONCLUSIONS: Exposure to rh MMP-7 resulted in promising proteoglycan loss in human surgical samples, normal rabbit intervertebral discs, and natural canine herniated discs. Administration of rh MMP-7 may facilitate the resorption process of herniated discs.     

注射胶原酶治疗腰椎间盘突出症的临床应用

１９９４年１２月至１９９６年８月，我院主要采用盘外注射（２３０例）部分患者采用盘内注射（２０例）胶原酶治疗腰椎间盘突出症，随访２００例，优良率达９１％。介绍了注射胶原酶的操作方法及注意事项，认为：胶原酶化学溶解术疗效好、创伤小、操作简单、安全、并发症少。髓核突出大小１０ｍｍ，髓核突出伴钙化，伴侧隐窝狭窄，手术治疗复发的椎间盘突出症等，不是盘外注射胶原酶治疗的绝对禁忌证。     

髓核化学溶解术的准备与观察处理

采用髓核化学溶解术(CNL)治疗腰椎间盘突出症1300余例。取得81.9%的优良率。作者介绍了CNL的适应症、影象学检查确定注射点、CNL前的辅助用药、以及CNL后的观察与处理等。     

经皮盘内注射臭氧联合补肾壮腰汤治疗腰椎间盘突出症

目的:探讨经皮盘内注射臭氧联合补肾壮腰汤治疗腰椎间盘突出症的价值。方法:40例腰椎间盘突出症病人经皮盘内注射浓度为35～50μg/ml的臭氧20～40ml,术后予患者口服验方补肾壮腰汤,通过视觉模拟评分、汉化Oswestry功能障碍评分、改良的Macnab方法对其治疗效果进行评价。结果:术后6个月根据改良的Macnab方法评价,其中优26例(65%),良10例(25%),可4例(10%),差0例。总有效率达到100%,优良率为90%。动态观察Oswestry功能障碍评分,随着时间的延长,患者功能逐渐恢复。术前、后比较,差异有统计学意义(P0.01)。结论:臭氧是一种新的治疗腰椎间盘突出症的手段,它有着安全、创伤小、有效率高、费用低、患者恢复快等优点,联合合理的验方,可进一步提高疗效,值得推广。     

胶原酶化学髓核溶解术机制的再研究

目的:研究胶原酶盘内注射对山羊腰椎间盘突出模型的化学髓核溶解作用,重新评估化学髓核溶解术的机制。方法:胶原酶注射前10周,通过手术损伤椎间盘前外侧纤维环诱发椎间盘突出和退变,并经MRI证实。胶原酶注射后1天、1周、2周、4周、12周观察X线片上椎间盘高度指数、椎间盘的组织学等变化。结果:胶原酶对正常和退变椎间盘髓核组织具有类似的溶解作用。胶原酶盘内注射后在突出模型椎间盘中央和髓核突出部位均出现溶解空腔,终板破坏轻;而对正常椎间盘溶解部位在椎间盘髓核和内层纤维环,并严重破坏终板。结论:盘内注射胶原酶能有效溶解山羊突出模型椎间盘的中央和突出部位髓核组织。胶原酶注射后12周,退变间盘基质出现再生能力。
