Documenting neuropathy of the lateral femoral cutaneous nerve using the Pressure-Specified Sensory Testing device.

Abstract

Entrapment of the lateral femoral cutaneous nerve has been difficult to document. The variability of the anatomic location of this nerve makes it difficult to measure with traditional electrodiagnostic studies. At the same time, anatomic variability increases the likelihood for this nerve to become entrapped within the inguinal ligament. The current study reports the ability to document the presence of this nerve entrapment in 24 patients, compared with 10 asymptomatic control subjects, by using nonpainful and noninvasive computer-assisted neurosensory testing with the Pressure-Specified Sensory Device.
