微创和传统开放后路腰椎椎间融合术治疗腰椎退行性疾病的远期预后

目的探讨微创后路腰椎椎间融合术(MIS-PLIF)和传统开放PLIF对腰椎退行性疾病(LDD)远期疗效及安全性的影响。方法 2011年1月-2014年12月收治LDD患者182例,其中96例采用传统开放PLIF治疗(PLIF组),86例采用MIS-PLIF治疗(MIS-PLIF组)。比较2组腰椎矢状位参数、多裂肌横截面积及萎缩率、融合率、疼痛视觉模拟量表(VAS)评分、日本骨科学会(JOA)评分、Oswestry功能障碍指数(ODI)及术后并发症发生情况,分析多裂肌萎缩率与顽固性腰背痛的相关性。结果 2组术后各随访时间点椎间隙高度恢复值和节段性前凸角恢复值差异均无统计学意义(P > 0.05)。2组术后1年腰椎前凸角恢复值差异无统计学意义(P > 0.05);但术后5年和末次随访时,MIS-PLIF组腰椎前凸角恢复值显著高于PLIF组,差异均有统计学意义(P < 0.05)。MIS-PLIF组术后各随访时间点多裂肌横截面积大于PLIF组,多裂肌萎缩率低于PLIF组,差异均有统计学意义(P < 0.05)。2组术后随访6个月融合率差异无统计学意义(P > 0.05)。2组术后各随访时间点下肢痛VAS评分差异无统计学意义(P > 0.05);MIS-PLIF组术后各随访时间点腰痛VAS评分、JOA评分及ODI均优于PLIF组,差异有统计学意义(P < 0.05)。MIS-PLIF组顽固性腰背痛发生率显著低于PLIF组,差异有统计学意义(P < 0.05)。合并顽固性腰背痛患者多裂肌萎缩率高于未合并顽固性腰背痛的患者,差异有统计学意义(P < 0.05)。结论术后多裂肌萎缩可能是导致顽固性腰背痛的重要原因,相较于传统开放PLIF,MIS-PLIF治疗LDD能够更有效地保持腰椎生理曲度,改善肢体活动功能,降低多裂肌萎缩程度,有助于避免顽固性腰背痛的发生。     

Surgical treatment of four segment lumbar spondylolysis: A case report

BACKGROUNDFour-level lumbar spondylolysis is extremely rare. So far, only 1 case has been reported in the literature. CASE SUMMARYA 19-year-old man presented with severe back pain irresponsive to conservative therapies for 2 years. Lumbar radiographs and two-dimensional computed tomography scan showed four segment lumbar spondylolysis on both sides of L2-L5. Lumbar magnetic resonance imaging showed normal signal in all lumbar discs. Because daily activities were severely limited, surgery was recommended for the case. The patient underwent four-level bilateral isthmic repair at L2-L5. During surgery, L2-L5 isthmi were curetted bilaterally, freshened, and then grafted with autologous iliac bone that was bridged and compressed with a pedicular screw connected to a sub-laminar hook by a short rod. The symptoms of back pain almost disappeared. He has been followed-up for 96 mo, and his symptoms have never recurred. Fusion was found in all repaired isthmi 14 mo after surgery according to evaluation of lumbar radiography and computed tomography scan.CONCLUSIONWe report here 1 case of four-level lumbar spondylolysis that was treated successfully with direct isthmic repair.

放松功辅助治疗腰椎间盘突出症的临床疗效观察

目的:观察放松功辅助治疗腰椎间盘突出症(LDH)的临床疗效。方法:2018年5月至11月于上海市气功研究所医疗门诊部收集63例LDH患者,将其随机分为治疗组(32例)与对照组(31例)。治疗组予以电针结合放松功治疗,对照组仅给予电针治疗,两组电针治疗频率均为每周2次,治疗组放松功习练频率为每天1次,每次约20min,两种治疗方法均连续治疗3个月。治疗前后,利用VAS评分、CODI指数、表面肌电指标进行临床疗效评定。结果:治疗组有效率为90.3%(28/31),对照组有效率为83.3%(25/30)。治疗后,治疗组VAS评分显著低于同期对照组(P<0.05),治疗组患侧与健侧多裂肌MF值均高于对照组同侧(P<0.05)。结论:放松功在改善LDH患者疼痛与腰部肌肉疲劳度方面疗效明显,值得进行临床推广应用。     

Genetics of intervertebral disc disease: A review

Intervertebral disc disease (IVDD) is a common musculoskeletal disease affecting about 5% of all individuals. It is characterized by lumbar disc herniation, which causes nerve root irritation, either mechanically or via inflammatory mediators, and results in radiating pain, known as sciatica. Numerous studies have been conducted to identify the causes and risk factors for IVDD. Lifting heavy loads, torsional stress, and motor vehicle driving are among the best-identified environmental risk factors. However, it has become evident recently from family and twin studies that genetic factors may also be important in IVDD. This hypothesis was strengthened by the identification of two collagen IX alleles associated with sciatica and lumbar disc herniation. In addition, disc degeneration has been shown to be related to an aggrecan gene polymorphism, a Vitamin D receptor and matrix metalloproteinase-3 gene alleles. This review highlights the genetic role and occupational aspects of IVDD.     

取环致宫腔化脓性感染引发腰椎间盘炎一例报道并文献复习

宫腔化脓性感染是一种严重的盆腔炎性疾病（PID），主要表现为发热、腹痛、阴道分泌物增多等症状。椎间盘炎是发生于椎间盘间隙和邻近椎体或软骨板的感染性病变，其症状及体征缺乏特异性，临床上容易诊断延迟直至出现椎体骨质破坏及下肢肌力减弱。本文报道了1例因取环手术引发宫腔化脓性感染进而引发腰椎间盘炎，出现腰痛伴行走障碍的患者，并进行了文献复习，加深了对PID的病原体、感染传播途径、诊断标准、治疗原则及其严重不良后果的认识。对于非特异性椎间隙感染，临床医生除实验室检查及影像学检查之外，还应仔细询问病史并了解病情的演变过程，及时诊断并进行手术治疗。     

Impact of age within younger populations on outcomes following cervical surgery in the ambulatory setting

ObjectiveTo determine the effect of age within the younger population seen at ambulatory surgical centers on patient-reported outcome measures (PROMs) after cervical spine surgery.MethodsPatients of age <65 years undergoing single-level anterior cervical discectomy and fusion (ACDF) or cervical disc replacement (CDR) were included. Patients were divided by mean age of initial population (46 years). PROMs included Patient-reported Outcome Measurement Information System Physical Function (PROMIS-PF), 12-Item Short-Form Physical Component Survey (SF-12 PCS), Visual Analog Scale (VAS) neck, VAS arm, Neck Disability Index (NDI) collected preoperatively and at postoperative time points up to 2 years.Results138 patients were included, with 66 patients <46 years. Both cohorts demonstrated improvement from preoperative baseline with regard to all studied PROMs at multiple time points postoperatively (p ≤ 0.042, all). Between groups, the older cohort demonstrated greater mean PROMIS-PF scores preoperatively and at 6 weeks (p ≤ 0.011, both), while VAS arm scores were lower in the older group at 1 year (p = 0.002), and NDI scores were lower in the older group at 6 weeks and 1 year (p < 0.027, both). Minimal Clinically Important Difference (MCID) achievement rates were greater in the younger group in PROMIS PF at 2 years (p = 0.002), and in the older group in VAS arm score at 1 year (p = 0.007).ConclusionBoth cohorts showed significant improvement at multiple postoperative time points for all PROMs. Between groups, the older group reported more favorable physical function, VAS arm, and NDI scores at several time points. However, MCID achievement rates only significantly differed in two PROMs at singular time points. Difference in age in patients <65 years likely does not significantly affect long-term outcomes after cervical spine surgery.     

视神经炎的临床特征分析及早期视盘和黄斑的改变

目的　研究视神经炎患者的临床特征及早期视盘和黄斑的改变。方法　回顾性分析山西省眼科医院视神经炎患者67例85眼。分析患者基本情况、眼科检查结果及OCT检查结果。结果　67例85眼中，男24例，女43例；28例（41.8%）发生于冬季；49眼（57.6%）入院时最佳矫正视力小于1.7 logMAR。视神经脊髓炎抗体阳性者出院和入院时的最佳矫正视力均较髓鞘少突胶质糖蛋白抗体阳性者差。患眼较健眼视盘周围神经纤维层增厚，杯盘面积比、杯盘垂直比、杯盘水平比、杯容积减小，盘沿面积、视盘面积增大（均为P=0.000）；与健眼相比，患眼早期上方、下方和平均黄斑区神经节细胞层厚度及黄斑区神经节细胞复合体的局部丢失体积、整体丢失体积均未发生明显改变（均为P＞0.05）。视盘水肿与患眼平均视盘周围神经纤维层厚度存在正相关（r=0.728，P=0.000）。结论　视神经炎多发生于女性，早期视力损害严重，视神经脊髓炎抗体阳性者视力预后差。早期由于视盘水肿，视盘周围神经纤维层增厚，盘沿面积、视盘面积增大；杯容积、杯盘比减小，早期病变未累及黄斑区。
