全内镜下可视化经椎弓根上切迹入路手术治疗腰椎侧隐窝狭窄症的疗效分析

目的:分析全内镜(full-endoscopic,FE)下可视化经椎弓根上切迹入路手术治疗腰椎侧隐窝狭窄症的临床疗效。方法:收集2016年6月～2017年12月在我院采用FE下可视化经椎弓根上切迹入路手术治疗的96例腰椎侧隐窝狭窄症患者的临床资料,其中男性62例,女性34例,年龄38～68岁(51.4±13.3岁);L3/4 8例,L4/562例,L5/S1 26例。术前腰、腿痛视觉模拟评分(visual analogue scale,VAS)分别为0～5(3.8±1.6)、3～7 (5.2±1.0);腰椎Oswestry功能障碍指数(ODI)为38%～65%[(53.0±9.1)%];手术节段侧隐窝角和前后径分别为17.6°±1.4°和2.3±0.2mm。术后完成至少2年随访。记录患者手术时间、术中透视次数、住院时间和围手术期并发症,在术后1周的CT/MRI横断面上测量手术节段侧隐窝角和前后径;术后1周、3个月、1年和末次随访时行下肢痛和腰痛VAS评分、ODI评定,并进行统计学分析;末次随访时参照改良MacNab标准评价临床疗效。结果:患者均顺利完成手术,手术时间55.8±14.6min,术中透视次数7.2±2.5次,住院3.7±1.9d。1例术后出现短暂性神经根麻痹,保守治疗1周内症状消失;6例术后症状残留,4例术后症状未改善。至末次随访时共有6例再次后路行翻修手术。术后侧隐窝角和前后径分别为39.5°±4.2°和6.2±0.4mm,均较术前显著性增加(P0.001)。所有患者均获得随访,随访时间24～32(26.6±5.6个月),术后1周、3个月、1年和末次随访时下肢痛和腰痛VAS评分、ODI均较术前显著性改善(P0.05)。末次随访时改良Macnab标准评定:优32例,良54例,一般6例,差4例,优良率为89.6%。结论:FE下可视化经椎弓根上切迹入路手术治疗腰椎侧隐窝狭窄症安全、有效,能够获得良好的短期临床疗效,但需要严格选择适应证,以免影响术后临床症状改善。     

椎体成形术结合后路短节段椎弓根固定治疗16例胸、腰椎转移性肿瘤

目的探讨后路短节段椎弓根钉棒系统结合瘤椎内骨水泥填充,治疗胸、腰椎转移性肿瘤的临床疗效。方法对2007年7月至2011年3月山东省济宁市第一人民医院脊柱外科收治的伴神经症状的16例胸、腰椎转移性肿瘤患者,施行后路椎管减压、瘤椎骨水泥填充、联合短节段椎弓根钉棒固定治疗。观察术后患者疼痛缓解、神经功能恢复情况及生存时间。结果围术期无死亡,切口均I期愈合,未发生感染或裂开。术后生存期均超过3个月,平均8.6个月(4.5～14.0个月)。术后患者疼痛程度、神经功能均有改善。结论椎体成形术结合后路短节段椎弓根固定治疗胸、腰椎转移性肿瘤安全、创伤小,能有效缓解患者疼痛,重建并维持脊柱稳定性,提高患者生存质量。     

自体髂骨植骨联合自体骨髓干细胞移植治疗骨折术后骨不连

BACKGROUND: Bone nonunion is a common complication in the orthopedic treatment, and its morbidity reached 5%-10%, which results in the long-term functional disturbance of the limbs, and even disability. Autogenous iliac crest graft has been commonly used to treat bone nonunion, but some limitations still exist. OBJECTIVE: To investigate the treatment outcomes of autogenous iliac crest graft combined with autologous bone marrow stem cell transplantation for bone nonunion after fracture surgery. METHODS: Clinical and follow-up data from 69 patients with bone nonunion were analyzed retrospectively. All patients were allotted to combination (n=37) and iliac (n=32) groups, followed by treated with autologous iliac crest graft combined with autologous bone marrow stem cell transplantation or  autologous crest graft, respectively. Afterwards, the hospitalization time, fracture healing time, bone mineral density and Fereadez-Esteve callus scores were detected and compared between groups. RESULTS AND CONCLUSION: The hospitalization time did not differ significantly between groups (P > 0.05). The fracture healing time in the combination group was significantly shortened compared with the iliac group (P < 0.05). The bone mineral density and Fereadez-Esteve callus scores in the combination group were significantly higher than those in the iliac group at 3 and 6 months after surgery (P < 0.05). The excellent and good rate of the affected limb function in the combination group was significantly higher than that in the iliac group (P < 0.05). These results suggest that autogenous iliac crest graft combined with autologous bone marrow stem cell transplantation for bone nonunion can accelerate fracture healing, promote porosis and improve the functional recovery of affected limbs. 中国组织工程研究杂志出版内容重点：组织构建;骨细胞;软骨细胞;细胞培养;成纤维细胞;血管内皮细胞;骨质疏松;组织工程
