中下段颈椎的应力松弛特性及前、后路手术对其的影响

目的 研究中下段颈椎的应力松弛特性，并评估椎间盘切除植骨术与椎板切开术对其影响。方法 6例新鲜尸体完整颈椎及手术后颈椎，在模拟生理状态下进行屈曲及伸展位的应力松弛实验。结果 在恒应变条件下，绘制术前及不同术式后的中下段颈椎的应力松弛函数及曲线；术后的中下段颈椎的应力和初始化应力比值G(t)比术前明显增大，前路椎间盘切除植骨术后的G(t)值比椎板切开术大，两者均有统计学意义。结论 在恒应变条件下，颈椎具有快速应力松弛敏感性，屈曲位比伸展位大。椎板成形术及颈椎前路椎间盘切除植骨术都使颈椎的应力松弛能力减弱，前路椎间盘切除植骨术的影响更大。     

经皮弧式椎间盘切除器械治疗腰5骶1椎间盘突出症初步报告

采用经皮弧式椎间盘切除器械治疗Ｌ_５～Ｓ_１椎间盘突出症２２例，２１例成功。术后优良率为８６．４％。该器械能够避开髂嵴阻挡进入Ｌ_５～Ｓ_１椎间隙，并增加椎间盘切除量，提高经皮Ｌ_５～Ｓ_１椎间盘切除成功率。定位正确是成功的关键。     

椎间盘部分切除对腰椎应力分布影响的有限元分析

腰椎间盘突出症是骨科常见病之一。椎间盘切除术被广泛应用于本症的治疗。本文采用有限元素分析法观察了椎间盘部分切除前后腰椎应力分布的改变。本研究观察到,在正常情况下,椎体上下缘的中央部位承受较大的应力;椎间盘部分切除术后,椎体上下缘的侧方承采应力大于中央部分。这些结果表明,椎间盘部分切除术后可引起腰椎应力分布紊乱,出现应力集中,引起骨质增生,从而影响手术的远期疗效。     

后路腰椎间盘镜治疗多节段腰椎间盘突出症

目的探讨多节段腰椎间盘突出症的后路腰椎间盘镜(MED)手术治疗方法。方法回顾性分析2000年至2004年经MED治疗的45例多节段椎间盘突出症的临床资料。结果对45例患者共93个椎间盘进行了手术，平均住院时间14．8d，平均手术时间92min，平均手术出血量145ml，术后随访3个月至40个月，手术优良率为91．6％。结论多节段腰椎间盘突出症是MED手术治疗的相对适应证，相对于单节段的MED手术，术前定位和术中操作更困难，严格的病例选择和全面的术前分析，辅以熟练的手术操作，仍可获得较为满意的疗效。     

Evaluation of Percutaneous Transforaminal Endoscopic Discectomy in the Treatment of Lumbar Disc Herniation: A Retrospective Study

ObjectiveThe objective of the present study was to evaluate the safety and efficacy of percutaneous transforaminal endoscopic discectomy (PTED) and open fenestration discectomy (OFD) in the treatment of lumbar disc herniation (LDH).MethodsPatients in our hospital with LDH who received PTED (n = 71) and OFD (n = 39) from 2013 to 2014 were retrospectively studied. Patient information, including age, gender, visual analogue scale (VAS) score for low back pain and leg pain, body weight, height, Oswestry disability index (ODI), Japanese Orthopedic Association (JOA), and recurrence, was collected. The patients in the two groups were followed up for an average of 63 months after surgery.ResultsA total of 136 patients completed the operation and 110 patients were followed up completely. There was no significant difference in baseline data between the two groups (P > 0.05). The postoperative low back pain, leg pain, ODI, and JOA of the two groups were better than those preoperatively (P < 0.05). One week after surgery, the recovery of PTED patients was better than that of OFD. The ODI score of the PTED group was lower than that of the OFD group (10 [8, 12] vs 14 [11, 16]; P < 0.05), the waist VAS score of the PTED group was lower than that of the OFD group (2 [2, 3] vs 3 [2, 4]; P < 0.05), the leg VAS score of the PTED group was lower than that of the OFD group (1 [0,1] vs 1 [1, 2]; P < 0.05), while the JOA score of the PTED group was higher than that of OFD group [19(16, 20) vs 12(10, 17); P < 0.05]. There were no significant differences in ODI, JOA, waist and leg VAS scores between the two groups at 1 month after surgery and at subsequent follow‐up (P > 0.05). At the end of the follow up, 89.7% (35/39) of patients in the OFD group had excellent improvement in the JOA score, and 88.7% (63/71) of patients in the PTED group had an excellent improvement. There was no significant difference between the two (P > 0.05). There was also no significant difference in the recurrence rate between the two groups [(5/71) vs (3/39); P > 0.05]. [Correction added on 05 March 2021, after first online publication: “3/29” was amended to “3/39” in the preceding sentence.]ConclusionBoth PTED and OFD can achieve good mid‐term efficacy in the treatment of LDH but PTED has certain advantages, including the small incision, a shorter hospital stay, and quicker, earlier recovery. However, prospective randomized controlled studies with a larger sample size are needed.     

侧后路椎间孔镜下髓核摘除术治疗青少年腰椎间盘突出症的早期疗效观察

目的探讨经皮侧后路椎间孔镜下髓核摘除术治疗青少年腰椎间盘突出症的临床疗效。方法 2010年2月~2011年7月,我院收治的12例青少年腰椎间盘突出症患者接受了经皮侧后路椎间孔镜下髓核摘除术治疗并获得随访。其中男8例,女4例;年龄12~20岁,平均14.6岁。比较手术前后Oswestry功能障碍指数(Oswestry Disability Index,ODI)、下肢疼痛视觉模拟评分(visual analogue scale,VAS)及术后12个月时Macnab评分对临床疗效进行分析。结果 12例患者均获得随访,随访时间17~30个月,平均21.3个月。术后1周、3个月,6个月,12个月及末次随访时ODI指数、下肢疼痛VAS评分与术前相比均明显降低,差异有统计学意义(P0.05)。按照Macnab评分标准,术后12个月时,优7例,良4例,可1例,优良率为91.7%(11/12)。结论经皮侧后路椎间孔镜下髓核摘除术治疗青少年腰椎间盘突出症短期内能取得满意的临床疗效,其长期疗效及安全性有待进一步研究。
