Ultrasound Evaluation of the Normal Ulnar Nerve in Guyon's Tunnel: Cross-sectional Area and Anthropometric Measurements
Background: Ulnar nerve (UN) entrapment is an infrequent disorder, but is often seen in long-distance cyclists. Electrodiagnosis and imaging modalities, including ultrasound, are used for diagnosis. The goal of this study was to obtain sonographic normative data of the UN in Guyon's tunnel, to...

There was a significant difference between female and male volunteers in the measurements of wrist width, wrist depth, wrist circumference, palm length, hand width, and UN CSA (p < 0.001). The UN CSA was correlated with wrist width, wrist depth, wrist circumference, palm length and hand width (p < 0.01).

Therefore, the contralateral side is more useful as a reference standard than the gender mean.http://www.sciencedirect.com/science/article/pii/S0929644115000764anthropometryreference valuesulnar nerveultrasonography |
