Sixteen pediatric radial mononeuropathies were seen among 2077 electromyograms performed in the electromyography laboratory at The Children's Hospital, Boston, during 16.5 years, 1979-1995. Eight (50%) of these radial neuropathies, including 2 in newborns with apparent prenatal onset, were atraumatic, primarily related to compression in 6 and entrapment in 2. The other 8 (50%) were traumatic related to fractures or lacerations. Electromyography documented the radial neuropathy to be localized to the proximal main radial nerve trunk in 2 (13%), distal main radial nerve trunk in 9 (56%), and posterior interosseous nerve in 5 (31%) children. Significant improvement was noted in 13 of the 16 radial neuropathies--within 6-12 weeks for demyelinating lesions and up to 17 months for axonal injuries. Rarely, a child with a chronic progressive radial neuropathy or a postfracture radial neuropathy that does not improve in 3 months may require exploration.
1979年至1995年的16.5年间，在波士顿儿童医院的肌电图实验室进行的2077例肌电图检查中，发现了16例小儿桡神经单神经病。其中8例（50%）桡神经病变为非创伤性，主要与6例受压和2例卡压有关，包括2例产前发病的新生儿。另外8例（50%）为与骨折或撕裂伤相关的创伤性病变。肌电图显示，2例（13%）患儿的桡神经病变局限于桡神经主干近端，9例（56%）局限于桡神经主干远端，5例（31%）局限于骨间后神经。16例桡神经病变中有13例有显著改善，脱髓鞘病变在6至12周内改善，轴索性损伤最长在17个月内改善。极少数情况下，患有慢性进行性桡神经病变或骨折后桡神经病变且3个月内无改善的儿童可能需要进行探查。
