Bilateral posterior interosseous nerve palsy is a rare case of radial nerve entrapment. The patient is unable to extend the fingers in the metacarpophalangeal joints. Extension of the interphalangeal joints is preserved due to the intrinsic muscles. Neither the extensor carpi radialis longus and brevis muscles are affected nor the brachioradialis muscle. However, extension of the wrist may be weak. There is no sensory loss. The neurophysiological examination underlines the clinical findings. In our case compression is caused by the arcade of Frohse and the vessels of the recurrent radial artery. A good recovery of nerve function is seen after surgical decompression.
双侧骨间后神经麻痹是一种罕见的桡神经卡压病例。患者无法伸展掌指关节处的手指。由于内在肌的作用，指间关节的伸展功能得以保留。桡侧腕长伸肌和桡侧腕短伸肌以及肱桡肌均未受影响。然而，腕关节的伸展可能会减弱。没有感觉丧失。神经生理学检查证实了临床发现。在我们的病例中，卡压是由弗罗瑟弓和桡返动脉的血管引起的。手术减压后可见神经功能良好恢复。
