文题释义:
股四头肌:大腿肌肉前面有股四头肌,后面有股二头肌,内侧有缝匠肌、内收大肌等。要使大腿强壮首要是发展股四头肌,因为股四头肌是人体最大、最有力的肌肉之一。股四头肌由4个头组成即股直肌、股中肌、股外肌和股内肌组成,肌腱构成人体最大的籽骨-髌骨和髌骨韧带。股四头肌的功能是使小腿伸、大腿伸和屈,伸膝(关节)屈髋(关节),并维持人体直立姿势。
外固定器在骨科中的应用:使骨外固定器治疗骨折成为一种公认标准方法的为前苏联著名学者Ilizarov,他发明的多孔性全环式外固定器,使用直径较细钢针(1.5 mm)张应力下固定,使得骨外固定稳定性和针道感染两个最主要问题得到了较满意的的解决。目前国内使用的外固定器种类很多,用的较多的骨外固定器有李氏半环槽式和仿De Bastiani 的单边式外固定器和潍坊三维可调式外固定器。
 
摘要
背景:在兔股骨骨折类造模实验中,关于股四头肌肌腱是否会影响固定装置稳定性的相关研究较少。
目的:分析股四头肌肌腱对兔股骨骨折模型中外固定架稳定性的影响。
方法:将48只新西兰大白兔随机分为2组,使用外固定架制作兔股骨骨折模型,实验组切断股四头肌肌腱,对照组保留股四头肌肌腱,2周后行X射线检查观察在骨折造模开始到成功阶段2组外固定架失效的数量。

结果与结论:①X射线检查:造模后2周实验组1只兔外固定架螺钉游离于股骨外,对照组7只实验兔外固定架螺钉游离于股骨外,其中1只螺钉折断,螺纹部分留置于股骨内;②外固定架失效率:实验组1只兔外固定架失效,失效率4%,对照组12只兔外固定架失效,失效率50%,差异有显著性意义(P < 0.05)。结果证明切断兔股四头肌肌腱可以有效地保证术后兔外固定架的稳定性,间接的提高了实验的成功率。

Abstract:

 BACKGROUND: In rabbit femur fracture model experiment, there are a few studies on whether quadriceps tendon will affect the stability of the fixed device. 

OBJECTIVE: To analyze the effects of quadriceps tendon to the stability of external fixator in rabbit models of femur fracture.
METHODS: The 48 New Zealand white rabbits were randomly divided into two groups. External fixator was used to make fracture model. In the experiment group, quadriceps tendon was cut. In the control group, quadriceps tendon was retained. 2 weeks later, X-ray examination was utilized to observe the number of failed external fixator in both groups from modeling to success. 
RESULTS AND CONCLUSION: (1) X-ray examination: 2 weeks after model establishment, external fixation frame screw was free from femur in one rabbit of the experiment group, and seven rabbits in the control group. Of them, one screw was broken. Threaded portion retained in the femur. (2) External fixation failure rate: failed external fixator was found in one rabbit in the experiment group, resulting in a failure rate of 4%, and 12 rabbits in the control group, resulting in a failure rate of 50% (P < 0.05). These findings suggested that cutting off the rabbit quadriceps tendon can effectively ensure the stability of the external fixator, and indirectly improve success rate of the experiment.
