Localisation of the radial nerve (RN) in the spiral groove by previously reported methods has a wide range and is generalised. The objective of this study was to establish a method unique to a patient to accurately localise the nerve.
The distance between RN at the midpoint of the spiral groove (D) and the tip of the olecranon (O) was compared with the most distal wrist flexion crease and fingertips on 100 healthy volunteers. The RN was found by ultrasound examination.
The mean distance from O to D was 16.22 cm (12.5-20.5 ± 1.55), and mean distances from wrist crease (WC) to second, third, fourth and fifth fingertips were 17.79 (14-20 ± 1.28), 18.66 (15-21 ± 1.32), 17.71 (14.5-20.5 ± 1.32) and 15.62 (12.5-20.5 ± 1.34) cm, respectively. With regards to O-D distance, the strongest relationship was obtained for the distance between the fifth fingertip to the WC (r = 0.708, < 0.001). This relationship was stronger among females than males ( < 0.001).
The course of the RN can be easily found at the upper arm by this method, which is unique to a patient.
This study presents a new and individualised approach to accurately predict the location of the RN in the spiral groove. This method is clinically relevant and can be used to guide the surgical explorations or expedite interventional methods.
采用先前报道的方法在螺旋沟中定位桡神经（RN）的范围较广且具有普遍性。本研究的目的是建立一种针对个体患者准确神经定位的独特方法。
在100名健康志愿者中，将螺旋沟中点处的桡神经（D）与尺骨鹰嘴尖端（O）之间的距离，与最远端腕部屈曲皱褶和指尖进行比较。通过超声检查找到桡神经。
从O到D的平均距离为16.22厘米（12.5 - 20.5 ± 1.55），从腕部皱褶（WC）到第二、第三、第四和第五指尖的平均距离分别为17.79（14 - 20 ± 1.28）、18.66（15 - 21 ± 1.32）、17.71（14.5 - 20.5 ± 1.32）和15.62（12.5 - 20.5 ± 1.34）厘米。关于O - D距离，第五指尖到WC的距离相关性最强（r = 0.708，< 0.001）。这种关系在女性中比男性更强（< 0.001）。
通过这种针对个体患者的方法，可以很容易在上臂找到桡神经的走行。
本研究提出了一种新的个体化方法，可准确预测螺旋沟中桡神经的位置。该方法具有临床相关性，可用于指导手术探查或加快介入方法。
