JBJS Case Connector 12(4):e22.00352, October-December 2022. | DOI: 10.2106/JBJS.CC.22.00352 Buy Metrics Abstract Case: A 21-year-old collegiate baseball pitcher presented with transient lateral arm pain and wrist extension weakness after pitching more than 1 inning. Physical examination was unremarkable at rest. Ultrasound-guided injection of the radial nerve at the level of the lateral intramuscular septum improved his symptoms. After decompression of the radial nerve, the patient noted resolution of his symptoms while pitching. Conclusion: Atraumatic radial neuropathy is a rare but documented phenomenon. As far as we know, this is the first reported case of a transient exertional radial neuropathy in an athlete at the level of the lateral intermuscular septum.
