Entrapment of the palmar cutaneous branch of the median nerve: A neuropathy difficult to notice

Abstract

Palmar cutaneous branch of the median nerve (PCBMN) arises at average 7 cm proximal to and at the radial side of the distal wrist crease. Isolated entrapment of PCBMN is rare and difficult to detect. The literature review only yielded case reports. In this study, we wanted to present two cases of rare palmar cutaneous nerve entrapment, wherein one patient was treated conservatively and the other one with surgery. In conclusion, pain and discomfort in the thenar region may be a manifestation of palmar cutaneous nerve entrapment. Careful evaluation and treatment planning are essential in these patients.
