对骨折治疗“优化选择”与“合理选择”的理解和思考

从合理化角度回顾了当前几种重要的骨折治疗理论体系的发展与演变,认为骨折治疗的最优原则是一种理想状态,现实中没有绝对最优只有相对合理。只有建立以患者为中心的思维体系,加强医疗逻辑思维能力,用多维思考的方式寻找矛盾的合理平衡点,始终坚守医学伦理道德底线,才能真正做到为每一位骨折患者进行最合理的治疗。     

司法鉴定的眼外伤眼眶爆裂性骨折的临床决策

研究分析涉及司法鉴定的眼部钝力伤致眼眶爆裂性骨折临床决策的特殊性,依据医学原理,做出有益于伤者康复及纠纷解决的决策.选取眼眶爆裂性骨折49例(49眼).其中内侧壁骨折30例,下壁骨折19例.致伤原因:斗殴25例,交通肇事17例,运动伤5例,自己意外伤2例.30例2周内接受手术治疗,眼球运动不受限,眼位满意,功能位无复视,2例特定方位复视,3个月后消失.19例拒不接受手术治疗,3个月后眼球不同程度内陷,16例功能位复视,眼球转动疼痛.眼眶骨折早期手术治疗预后佳,后患少,对受伤者及肇事者均有益.     

中西医结合治疗骨折的临床思维方法

骨科医生在骨折治疗中需要科学的方法论指导。系统论的思想应用于中西医结合治疗骨折,它能从人体的总体出发,在“动与静”、“筋与骨”、“内与外”、“人与物”四对矛盾的相互作用中,揭示损伤的性质和骨折愈合的规律,有助于获得骨折的最佳治疗原则,有助于提高认识水平和实践能力。     

成人肱骨髁间髁上骨折的手术治疗体会

观察经尺骨鹰嘴截骨入路双柱铜板治疗肱骨髁间髁上骨折临床疗效。13例肱骨髁间髁上骨折患者经尺骨鹰嘴截骨入路双柱钢板治疗,结果13例患者获9个月～14个月的随访,末次随访肱骨髁间髁上及尺骨鹰嘴骨折均获得骨性愈合;2例合并尺神经原发损伤经对症处理及神经营养治疗6个月后症状消失,1例患者出现肘关节周围骨化性肌炎,肘关节屈曲僵硬畸形Mayo肘关节功能评分优8例,良3例,可1例,差1例,优良率达84．6％。因此,在肱骨髁间髁上骨折的手术治疗中尺骨鹰嘴截骨入路对于显露骨折断端固定方便可靠,对于促进骨折愈合,肘关节的早期功能锻炼有良好的临床疗效。     

加压空心钉固定技术对比锁定钢板技术治疗桡骨远端骨折的疗效分析

对比不同手术方法对桡骨远端骨折的疗效.收集我院自2008年10月到2012年12月桡骨远端骨折患者86例,双盲随机分成试验组和对照组,试验组采用无头加压空心钉内固定,对照组采用锁定钢板内固定,比较两组的平均手术时间和平均术中出血量.术后12个月采用Jakim标准进行腕关节功能评定,同时对随访患者的腕关节功能进行临床评分.试验组平均手术时间为（30.45±5.14）min,显著低于对照组的（63.42±8.14）min（P＜0.05）,而试验组平均术中出血量为（23.67±6.14）ml,少于对照组的（83.12±10.47）ml（P＜0.05）.术后随访试验组腕关节功能优良率为87.5%;对照组则为87.1% （P＞0.05）,试验组和对照组腕关节在功能、握力活动范围等方面评分存在显著差异,在疼痛评分上两组无明显差异.采用无头加压空心钉治疗桡骨远端骨折可以显著减少手术时间及术中出血,提高腕关节功能而且在疗效上与传统锁定钢板治疗桡骨远端骨折相比无明显差异.     

Shear-driven damage of ductile metals induced by indentation load

Although indentation does not induce apparent cracking in ductile materials, degradation of elastic stiffness of ductile metals has been found in micro-/macro- indentation tests. After comparing the predicted degradation by extended damaged-plasticity models with that measured by experimental testing, it is found that the softening caused by distortion of existing voids is inadequate to cause the notable degradation of elasticity. It is suggested that an independent damage-nucleation mechanism arising from shear deformation may exist. Although attractive in practical applications for its non-destructive nature, the damage-based indentation technique for estimating the fracture properties of ductile materials needs further investigation.     

Changing caring behaviours in rehabilitation after a hip fracture – A tool for empowerment?

Different rehabilitation programs after surgery have been presented to improve the outcome for patients with a hip fracture. Empowerment has been suggested as useful, but requires a change in the caring behaviours of health professionals. The aim with this study was to evaluate if training and supervision of the nursing staff could alter caring behaviours. A case-control study of nursing staff treating hip fracture patients was performed at a hospital with two sites. Training and supervision was given to the nursing staff at the intervention site. The intervention focused on creating positive care interaction by using eight guidelines. The evaluation was performed with recordings of a constructed caring situation before training, and observations of care situations at the ward before and after intervention. The results showed no differences at baseline between the two sites in the caring behaviours. After intervention, significant effects of caring behaviours were seen in seven out of eight guidelines, the effect sizes ranged from medium to large. The findings indicate that the nursing staff can change caring behaviours and facilitate the empowerment of patients with a hip fracture.     

后路椎弓根内固定治疗胸腰段骨折不同植骨方法临床疗效比较

为了比较后路椎弓根螺钉复位内固定治疗胸腰段骨折不同植骨方法的临床疗效,2002年1月-2006年9月,经后路椎弓根螺钉复位内固定手术治疗胸腰段骨折140例。比较分析各组伤椎高度矫正丢失,脊柱后凸成角矫正丢失,脊髓神经功能恢复,内固定失效及腰背疼痛并发症情况。结果显示,伤椎前、后缘高度比值和脊柱后凸成角术前4组差异不具有显著性意义,椎弓根螺钉复位内固定结合不同植骨融合方法,可以减少单纯内固定矫正丢失和内固定失效及腰背疼痛并发症。经椎弓根椎体内植骨可增加前中柱的稳定性,临床治疗优于脊柱后方植骨融合。     

骨折移位问题的科学认识

运用科学认识的规律和模式,进行骨折移位问题科学认识的具体分析,以理解骨折移位问题的新的理论知识及应对策略,从而有效地预防骨折再移位。因此,从科学认识的角度,能理解骨科各种新理念和新技术的发展,能消除对骨科治疗方法不断变化的疑问,以解除临床实践中存在的困惑,为患者提供最合适的治疗手段。
