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

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 cadavers to identify the course of the nerve, the effects of applying regular pressure to the corresponding region were evaluated in fencing athletes, focusing on changes in wrist-related pain and grip strength.The median nerve was located 2.3 cm medially from the styloid process of the radius, while the PCB was positioned 2.9 cm medially.The branching point of the PCB was identified at 3.7 cm proximal to the distal end of the radial styloid process.In fencing athletes, the application of targeted pressure to this region resulted in a reduction in wrist pain and an improvement in grip strength.When applied consistently, these effects were sustained across all participants.It is hoped that these findings will contribute to both surgical guidance and the development of effective non-invasive recovery strategies.
