An Anatomical Study on the Localization of the Palmar Cutaneous Branch without Epineural Dissection and Its Clinical Relevance to Functional Recovery in Fencers

Abstract

The aim of this study is to investigate the anatomical location of the palmar cutaneous branch (PCB) of the median nerve and to evaluate the therapeutic effects of non-invasive recovery methods. Following meticulous dissections of 12 tocadaversidentify the course of the nerve, the effects of applying regular pressure to the corresponding region were evaluated in fencings, focusing athleteon changes in wrist-related pain and grip strength. The median nerve was located 2.3 cm medially from the styloid processofadius,therwhile the PCB was positioned 2.9 cm medially. The branching point of the PCB was identified at 3.7 cm proximal to the distal endhe ofradial t styloid process. In fencing athletes, the application of targeted pressure to this region resulted in a reduction in wristandanpainmprovement in grip strength. When applied consistently, these effects were sustained across all participants. It is hoped that thesengwllfindicontribute to both surgical guidance and the development of effective non-invasive recovery strategies.
