Volar plate avulsion fracture (a, b). The fragment was reduced, and a hook plate was placed over the fracture fragment, with the proximal hook end capturing the soft volar plate after opening the A3, C2, and C3 pulleys and then retracting the deep and superficial flexors (c, d). Plain radiography 55 months post-operation revealing that the osseous fragment was well united. The total range of MP joint motion was 100%, and the pinching strength was 90% compared to the values of the same contralateral joint (e, f)
