Carpal Tunnel Symptoms With Normal Nerve Conduction Study Findings in Patients With Bifid Median Nerve Treated With Ultrasound-Guided 5% Dextrose Hydrodissection: A Case Series.

The most common entrapment neuropathy is carpal tunnel syndrome (CTS), which is caused by compression of the median nerve as it travels through the carpal tunnel in the wrist. Nerve conduction studies (NCS) and ultrasound were used to diagnose CTS but neither method is 100% accurate. The benefit of perineural dextrose injection has been supported in the literature. This article presents three cases with bifid median nerve (BMN) in whom median nerve entrapments were not detected with NCS, and symptom relief was provided with hydrodissection with 2 ml 5% dextrose.
