When initial treatment and rehabilitation are inappropriate, it may leave severe dysfunction in hand infection. We experienced rehabilitation with postoperative hand based splint therapy and obtained good results. Case 1: A 59-yearold male stuck chopsticks in the right-hand metacarpus, the middle of the left volar hand was painful. The postoperative rehabilitation conducted blocking exercise and adductor stretching. There are not the pain and excursion restrictions. Case 2: A 64-year old male was operated for purulent flexor tendon tenosynovitis. The postoperative rehabilitation was done in the same method and there are not the pain and excursion as Case 1. Enforcement of careful exercise therapy depending on an episode of care is important.
