Rapid ultrasonographic diagnosis of radial entrapment neuropathy at the spiral groove
Journal of the Neurological Sciences(2008)
摘要
Entrapment neuropathy of the radial nerve at the spiral groove region is relatively common. However, its localization may be technically challenging.To evaluate the use of ultrasound (US), in relation to electrophysiological testing, for this purpose.We studied 32 normal controls to obtain US parameters of the radial nerve. In addition, 10 patients with suspected radial neuropathy were tested using US and electrophysiological techniques.US examination correctly identified all 6 patients with radial neuropathy. The other 4 patients with alternate diagnoses did not show US abnormalities exceeding that of normal controls. US examination required a significantly shorter time than electrophysiological testing.US is of value as a rapid diagnostic adjunct for the localization of radial nerve entrapment.
