Outcomes and Therapy Contents after Tamai Zone I-IV Replantation

Abstract

  We investigated %TAM, grip strength, perception, and DASH (JSSH Version) in patients who underwent replantation following complete finger amputation, categorized according to the Tamai Zone classification. In Zone I and II, the postoperative outcomes were generally favorable; however, instances of poor sensory recovery were observed, suggesting that detailed therapy, including sensory re-education, may be required. In Zone III, the range of motion of the DIP joint may decrease. Therefore, it is important to focus on obtaining satisfactory range of motion in the PIP joint. In Zone IV, early postoperative emphasis should be on achieving finger extension range of motion, so that only flexor tendon tenolysis is necessary as a second-stage procedure. Recently, patients have diverse life backgrounds; thus, it is important to set individual goals, such as specific acquisition angles for each finger, and appropriate treatment strategies.
