Abstract
Introduction: Carpal tunnel syndrome is the entrapment neuropathy of median nerve at wrist. Bifid median nerve is a variation in the normal anatomy and can be associated with carpal tunnel syndrome. We aim to study the prevalence of bifid median nerve in patients with moderate to severe carpal tunnel syndrome.
Methods: An observational study was done in 74 patients with moderate to severe carpal tunnel syndrome for anatomic variations in the median nerve. The ultrasound evaluation of the wrist was performed in all patients. The datas were statistically analysed.
Results: The bifid median nerve was present in 12.2% and persistent median artery in 4.1% of the patients.
Conclusion: The bifid median is relatively common in patients with CTS. The ultrasound evaluation of the carpal tunnel is recommended in all patients with CTS.
Keywords: Carpal tunnel syndrome, bifid median nerve, persistent median artery.
