Twenty-four cadaveric arms were dissected to determine the position of the radial nerve on the posterior aspect of the humerus relative to the posterior tip of the acromion, the medial and lateral epicondyles, the division between the lateral and long heads of the triceps, and the triceps aponeurosis. The radial nerve passed anterior to the long head of triceps and cross onto the posterior shaft of the humerus an average of 124 mm below the posterior tip of the acromion. It was never closer than 97 mm. The nerve usually lies on the medial head of the triceps as it courses posteriorly around the humerus and then leaves the posterior shaft of the humerus an average of 126 mm above the lateral epicondyle and 131 mm above the medial epicondyle. It was never within 100 mm of either epicondyle. The surgeon can use these landmarks as guidelines to avoid the radial nerve during operative intervention on the humerus.
解剖了24具尸体的手臂，以确定桡神经在肱骨后侧相对于肩峰后尖、内外上髁、肱三头肌外侧头和长头之间的分界以及肱三头肌腱膜的位置。桡神经在肱三头肌长头前方通过，平均在肩峰后尖下方124毫米处跨过肱骨干后侧。其距离从未小于97毫米。当神经围绕肱骨后侧走行时，通常位于肱三头肌内侧头，然后在外侧上髁上方平均126毫米、内侧上髁上方平均131毫米处离开肱骨干后侧。其距离任何一个上髁均不超过100毫米。外科医生在对肱骨进行手术干预时，可以将这些标志作为避免损伤桡神经的指导。
