The Froment-Rauber nerve is a rarely described anomalous nerve arising from 1 of the terminal branches of the radial nerve that provides innervation to intrinsic hand muscles. We describe a 26-year-old man who had a traumatic radial nerve injury that resulted in first dorsal interosseous muscle wasting. He presented to our clinic 2.5 years post-injury, after having had unnecessarily undergone surgical exploration of the ulnar nerve.
The patient's history, clinical examination, and multiple electrodiagnostic tests were reviewed.
All findings were consistent with a diagnosis of anomalous innervation via a Froment-Rauber nerve.
Understanding this rare phenomenon may aid in diagnosing confusing clinical cases and prevent unnecessary procedures.
Froment-Rauber 神经是一种很少被描述的异常神经，它起源于桡神经的一个终末分支，为手部内在肌肉提供神经支配。我们描述了一位 26 岁的男性，他因外伤导致桡神经损伤，导致第一背侧骨间肌萎缩。他在受伤后 2.5 年就诊于我们的诊所，此前曾因尺神经不必要的手术探查。
回顾了患者的病史、临床检查和多项电诊断测试。
所有检查结果均符合异常通过 Froment-Rauber 神经支配的诊断。
了解这种罕见现象可能有助于诊断复杂的临床病例，并防止不必要的手术。
