The purpose of this study is to predict the location of radial nerve (RN) utilizing palpable anatomic landmarks. Thirty-four paired upper limbs were dissected. The RN was localized: (1) at the humeral spiral groove (SG), (2) lateral intermuscular septum (LIS), and (3) at its' division into the posterior interosseous nerve (PIN) and radial sensory nerve (RSN). The PIN was located at the anterior aspect of the radial neck (AN). Humeral and radial lengths were measured. The RN traversed the SG, on average, 48% (36%-63%) of humeral length, distal to the greater tuberosity. The RN pierced the LIS, on average, 38% (29%-56%) of humeral length, proximal to the lateral epicondyle (LE). The PIN/RSN division occurred on average 1.0 cm (-11.4 to 3.5) distal to the LE. The PIN crossed the AN, on average, 10% (5%-14%) of radial length, distal to the radial head articular surface.
本研究旨在利用可触及的解剖标志预测桡神经（RN）的位置。对 34 对上肢进行解剖。RN 的定位：（1）在肱骨螺旋沟（SG）处，（2）在外侧肌间隔（LIS）处，以及（3）在其分为后骨间神经（PIN）和桡神经感觉支（RSN）处。PIN 位于桡骨颈（AN）的前侧。测量肱骨和桡骨的长度。RN 平均在肱骨长度的 48%（36%-63%）处穿过 SG，位于大结节的远端。RN 平均在肱骨长度的 38%（29%-56%）处穿过 LIS，位于外侧髁的近端。PIN/RSN 分支平均距离 LE 远端 1.0cm（-11.4 至 3.5）。PIN 平均穿过 AN，占桡骨长度的 10%（5%-14%），位于桡骨头关节面的远端。
