肘关节不同位置对正中神经和桡神经位移影响的X射线评价
Impacts of the elbow in different positions on the displacement of median nerve and radial nerve:an X-ray evaluation
摘要
Abstract
BACKGROUND:The position of median and radial nerves corresponding to elbow is usual y 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.关键词
