Objective : There are controversial opinions on the location of PC8 (Nogung). The one is to localize the point between the 2nd and 3rd metacarpal bone, the other is to localize the point between the 3rd and 4th metacarpal bone. The study was performed to provide an experimental evidence to standardize the location of PC8 point. Methods : We employed 30 healthy adults evenly in sex. To identify the location of PC8 in the hand, we took X-ray photograph in both hands of participants. Thin layer of leads were pasted on to PC7 and tip of middle finger prior to take X-ray photograph. The line connecting two points corresponding to the leads in X-ray film was read by a radiologist to decide that the line passes which side between the 2nd metacarpal space and the 3rd one. Results and Conclusions: The line passed the 3rd metacarpal space in 49 cases out of 60 hands (82 %). Data suggest that PC8 could be localized at the point between the 3rd and 4th metacarpal bone.
