Abstract:
The concept of Pilon fractures was firstly introduced by Destot of France in 1911. Although the medial, lateral, and posterior malleoli may be involved, the definitive feature of Pilon fracture is involvement of the supra-articular metaphysis of distal tibia, which typically exhibits various degrees of impaction and comminution, combined with articular cartilage damage and joint surface incongruity. The most widely used and accepted classification methods for Pilon fractures are R?edi-Allgwer’s classification (1969) and AO/OTA comprehensive classification system (1996). In the former system, Pilon fractures are subdivided into types Ⅰ,Ⅱ, and Ⅲaccording to the increasing severity of joint surface comminution and displacement, while in the AO system, there are 2 types(43-B and 43-C), 4 groups (43-B3, 43-C1, 43-C2, 43-C3), and 12 subgroups. Burwell-Charnley’s(1965)radiographic criteria of reduction and Tornetta's (1993)criteria for clinical results have been devised for evaluation of the treatment of Pilon fractures. Mazur’s ankle evaluation grading system (1979) and Baird-Jackson’s ankle scoring system(1987)are also used.
