Potential palmar danger zones for nerve injury in percutaneous needle fasciotomy

Percutaneous needle fasciotomy (PNF) is a low morbidity option to release Dupuytren's contractures. 1 Lancerotto L. Davidson D.M.

Direct nerve injury is often attributed to spiral cords, which displace or entrap proper digital nerves (PDNs), increasing their vulnerability. However, common digital nerves (CDNs) are also vulnerable in the proximal palm, where they emerge from the carpal tunnel and fan out over the flexor tendons, lying directly beneath the pre-tendinous fascial bands in an area where needle cordotomy sites might be positioned. 2 Eaton C.
