Medición del nervio mediano mediante ultrasonido en población universitaria asintomática y su correlación con posibles factores de riesgo de síndrome de túnel carpiano.

Abstract

Introduction: The use of ultrasonography is useful in the diagnosis of carpal tunnel syndrome (CTS), it is based on the median nerve area. The range of this measure has been studied in European and Asian populations from 6,83 mm2 to 8,2 mm 2. Due to the anthropometric differences of our population this study is performed to know if there are differences in the median nerve area with other populations. Objective: To measure the median nerve area by ultrasound and to associate it with anthropometric data and possible risk factors for CTS. Methods and materials: Observational, cross-sectional study among university students aged 17-37 years. Ultrasound was performed to measure the median nerve area in both hands, at the level of the carpal tunnel. Results: A total of 176 college students were included, among whom the median nerve area of the right hand was 7.28mm2 and the left hand 7.93mm2. The median nerve area at low weight was 7.23 mm 2, average weight 7.79 mm 2 , over weight 8.01 mm2, obese 9.45 mm2, making a Pearson corelation between the median nerve area and the obesity BMI was 0.76 (p 0,01). Conclusion: The median nerve area in our study was similar to other populations. In our population the median nerve area increases according to BMI.
