Mallet fracture (a). The mini-hook plate captured the dorsal avulsed fragment, and the joint was reduced (b). Plain radiography 5 years post-operation revealing that osseous union, no metal failure, and no subluxation of the joint. However, an irregular articular surface is visible (c). The total range of DIP joint motion was 69%, and the pinching strength was 43% compared to the values of the same contralateral joint (d, e)
