정상 성인 여성에서 외측대퇴피신경의 초음파 소견

Abstract

Objective: To determine the lateral femoral cutaneous nerve (LFCN) ultrasonographic dimensions, nerve pathway, and regional anatomy. Method: Thirty healthy, asymptomatic adult women participated in this study. Using ultrasonography (US), we measured the cross-sectional circumference, area, diameter of the LFCN and the distance from the anterior superior iliac spine (ASIS) to LFCN. Height and weight of the subjects were obtained and body mass index (BMI) was determined. Correlation between the measured parameters and age and body mass index (BMI) was observed Result: The mean circumference, area, longitudinal and transverse diameters were 8.5±0.4 mm, 4.5± 1.0 mm2, 3.5±0.3 mm, and 1.5±0.2 mm, respectively. The mean distance between the ASIS and LFCN was 3.4±0.8 mm. There was no correlation between the US parameters and BMI or age. Conclusion: High-resolution US examination may be a useful tool in the evaluation of LFCN and diagnosis of meralgia paresthetica.
