title: A Novel Surgical Technique for Chronic Mallet Finger Injury: A Case Report.
abstract: A 39-year-old man injured his left little finger and was diagnosed with chronic tendon mallet with -50° of extension and 80° of flexion at the DIP joint. We performed an anatomical reconstruction of the terminal tendon and both lateral bands with divided palmaris longus tendon grafting. Postoperative range of motion at the DIP joint improved to -5° of extension with no flexion loss. We demonstrated a novel surgical technique for chronic tendon mallet injury that might represent a useful choice for the treatment of chronic mallet finger injury.
