Spectrum of injuries: 1) Low energy rotational fx’s Ankle type fractures / Skiing, simple falls . Fractures were classified by six evaluators (three foot and ankle surgeons and three orthopaedic surgery residents) using CT scans according to the morphological grading of the new pilon fracture classification system developed by Leonetti et al. The CT shows the five common fragments (anterior, posterior, medial, anterolateral and die-punch). Source. 1/3 of patients have associated injuries . The new system divides pilon fractures according to 4 labeling factors: 1) if the articular surface is involved, 2) the number of articular fragments, 3) the direction of major fracture line, and 4) areas of comminution. Reference: Ruedi, T. P. and M. Allgower (1979). In 2017, Leonetti and Tigani published a new classification system of pilon fractures based on CT. Created Apr 04, 2012 02:40.

In the AO/OTA classification for long bone fractures, pilon fractures are classified as extra-articular (43A), partial articular (43B), and intra-articular (43C), and further subclassified based on the degree of comminution. The pilon fracture was first described by Destot (1) in 1911. KEY FACTS • The tibial pilon fracture is a rare, yet devastating injury.
