文题释义：
关节镜：关节镜是一种观察关节内部结构的直径5 mm左右的棒状光学器械，是用于诊治关节疾患的内窥镜。关节镜在一根细管的端部装有一个透镜，将细管插入关节内部，关节内部的结构便会在监视器上显示出来。关节镜不仅用于疾病的诊断，而且已经广泛用于关节疾病的治疗。关节镜手术是一种微创手术，开始主要应用于膝关节，后相继应用于髋关节，肩关节，踝关节，肘关节及手指等小关节等。
正中神经：正中神经在肘关节上端，在肱动脉内侧进入肘窝，在肘窝处位于肱二头肌腱膜与肱肌之间，在肘窝的内侧缘多穿旋前圆肌浅、深两头进入前臂。因正中神经在肘关节前方与关节囊的位置关系密切，在行肘关节镜手术时易损伤此神经引起严重并发症。
摘要
背景：以往对正中神经和桡神经与肘关节骨性标志的位置关系是通过宏观测量工具进行测量，但在肘关节弯曲时不能使神经保持原位，得到数据误差较大。
目的：用X射线测量分析肘关节处于不同位置时对正中神经和桡神经的影响。
方法：选取10具新鲜冷冻的上肢尸体标本。测量肘关节处于伸直、伸直半旋前、屈90°和屈90°关节囊内注射生理盐水时对正中神经和桡神经与肘关节内骨性标志距离的影响。
结果与结论：①前臂伸直位与伸直半旋前位对正中神经和桡神经的位置没有影响(P > 0.05)；②肘关节由伸直位变为屈90°位增加正中神经及桡神经与肘关节内骨性标志的距离(P < 0.05)；③屈90°位关节囊注射生理盐水与注射生理盐水前比增加正中神经及桡神经与肘关节内骨性标志的距离(P < 0.05)；④结果说明，肘关节不同位置会引起正中和桡神经的位置发生变化；屈关节和关节内注射生理盐水增加正中神经及桡神经与关节囊内骨性标志的距离。

Abstract:

BACKGROUND: The position of median and radial nerves corresponding to elbow is usually estimated by macroscopical measurements, but there are big data errors when the elbow is bent.
OBJECTIVE: To measure and analyze the impacts of elbows in different positions on median and radial nerves under X-ray.
METHODS: Ten fresh frozen upper limb specimens were selected. The distance of median and radial nerves to the osseous marks inside the elbow was measured when the elbow was in extension, extension-half pronation, bent at flexion 90 degrees and bent at 90 degrees with the injection of normal saline into the joint capsule, respectively.
RESULTS AND CONCLUSION: The positions of median and radial nerves were not influenced when the elbow was in extension or in extension-half pronation (P > 0.05). The distance of median and radial nerves to the osseous mark of the elbow was significantly lengthened when the elbow was moved from from extension to was bent at 90 degrees (P < 0.05). The intra-articular injection of normal saline when the elbow flexion 90 degrees significantly elongated the distance of median and radial nerves to the osseous mark of elbow (P < 0.05). These results suggest that the elbow in different positions can induce the displacement of median and radial nerves. In addition, the distance between median, radial nerves and the osseous marks of the elbow is obviously lengthened when the elbow is in flexion with intra-articular injection of normal saline.
