We dissected 21 cadaver elbows to determine the relationship of the posterior interosseous nerve to the posterolateral approach to the elbow and head of the radius. At the distal end of the exposure the first branches at risk, those to extensor carpi ulnaris, were on average 6.0 +/- 1.0 cm (4.0 to 8.4) from the articular surface of the radial head. When using the posterolateral approach it is important that the interval between extensor carpi ulnaris and anconeus is clearly identified with the forearm fully pronated. The supinator should be released close to its ulnar border. It is safe to expose the proximal radius as far as the distal aspect of the bicipital tuberosity.
我们解剖了21具尸体的肘部，以确定骨间后神经与肘部后外侧入路及桡骨头的关系。在暴露的远端，首先有风险的分支，即尺侧腕伸肌的分支，距桡骨头关节面平均为6.0±1.0厘米（4.0至8.4厘米）。使用后外侧入路时，在前臂完全旋前的情况下，明确识别尺侧腕伸肌与肘肌之间的间隙非常重要。旋后肌应在靠近其尺侧缘处松解。暴露桡骨近端直至肱二头肌结节远端是安全的。
