About

Mallet finger is an avulsion fracture of the distal phalanx or rupture of the extensor terminal band caused by distal interphalangeal (DIP) joint hyperflexion or axial loading. In the treatment of mallet finger fractures, surgical repair is recommended in cases where the fracture involves more than one-third of the distal phalanx joint surface or the distal phalanx becomes volar subluxated

The blocking k.wire and micro plate technique are some of the methods used in the treatment of mallet finger fractures In recent years, the blocking k.wire technique has gained popularity owing to its minimally invasive nature and its ability to achieve satisfactory postoperative results

The main advantages of Micro Plate technique include provision of anatomical reduction and stable fixation, avoiding the risk of fragmentation of the small dorsal fragment, allowing early movement and increasing patient comfort and compliance
