简介:摘要目的介绍双带袢纽扣钢板技术重建喙锁韧带治疗完全性肩锁关节脱位的手术方法和临床疗效。方法自2010年3月~2011年10月对17例RockwoodⅢ型完全性肩锁关节脱位采用双带袢纽扣钢板技术重建喙锁韧带内固定治疗。其中男性12例,女性5例;年龄27~58岁,平均36.6岁。采用Lazzcano标准评定肩关节功能情况。结果17例均获得随访6-18个月。所有患者术后X线片检查显示肩锁关节均获得解剖复位。术后1-2个月肩关节功能活动基本恢复正常,基本无痛或轻微疼痛。17例均获得随访6-18个月。平均11.3月。按Lazzcano标准评定肩关节功能17例中,优13例,良4例,优良率100%。结论双带袢纽扣钢板技术重建喙锁韧带治疗完全性肩锁关节脱位具有手术时间短,创伤小,固定稳定牢固,更符合肩锁关节生物力学要求,可早期进行功能锻炼,无需二次手术拆除内固定等优点,疗效满意。
简介:摘要目的评价三纽扣钢板技术治疗急性完全性肩锁关节脱位的中期疗效。方法选取2010年5月-2013年4月我院收治的90例急性完全性肩锁关节脱位患者,随机分为观察组和对照组,其中观察组45例,采用三纽扣钢板技术治疗,对照组45例,采用AO锁骨钩钢板技术治疗,观察并比较两组患者手术时间、术后Constant及VAS评分。结果察组平均手术时间为(139.0±37.6)min,对照组平均手术时间为(43.4±15.1)min,两组患者平均手术时间比较差异有统计学意义,P<0.05;观察组术后3个月Constant评分明显高于对照组,相比较差异有统计学意义(P<0.05),但术后1年及术后2年两组差异无统计学意义(P>0.05),术后2年根据Constant评分情况评价两组患者疗效显示,观察组优良率95.6%(28例优,15例良,2例一般),对照组优良率84.4%(22例优,16例良,7例一般),相比较差异有统计学意义(P<0.05);观察组术后3个月VAS评分相比于对照组差异有统计学意义(P<0.05),但术后1年及术后2年相比较差异无统计学意义,P>0.05。结论三纽扣钢板技术相比于AO锁骨钩钢板技术治疗急性完全性肩锁关节脱位更有利于早期恢复患者肩关节功能及缓解疼痛,值得在临床上予以推广。

简介:AbstractAtopic dermatitis (AD) is a chronic inflammatory skin disease with xerosis, itchiness, as well as interconnection with immunoglobulin E (Ig E), mediated foods including airborne allergies. AD is not only related to the diminished stratum corneum barrier but also presents with an unusual expression of tight junctions (TJs) proteins. TJ barrier dysfunction leads to impairment in the stratum corneum (SC) barrier. The significant role of TJs in the epidermal barrier as indicated by Claudin-1 (Cldn-1) deficient mice that undergo high transepidermal water loss (TEWL) and skin dehydration. In atopic dermatitis, downregulation of Cldn-1 was observed due to inflammation. Still, a lack of distinct understanding exists in considering tight junction barrier impairment as a cause or outcome in atopic dermatitis. This review summarizes TJs main role in skin barrier function and TJ proteins (TJPs) expression observed in AD patients.
