It is important in this kind of fractures to have a good mobility after treatment (Mills & Nork SE, 2002). Instead of the standard treatment with one or two plates and screws, one should try to use the reduction of the fracture's fragment with Kirschner wires under Rx control and fix the fragments with K wires, screws and external fixation (Marsh et al., 1995; Morandi & Pearse, 1996). Open reduction and internal fixation has a significant complication rate and this has encouraged interest in percutaneous techniques, most of which associate arthroscopy and fluoroscopy. Arthroscopy is useful to provide a good view of the articular surface and allows assessment of associated intra-articular lesions.

The objectives of this treatment are to obtain a good articular congruity, axial alignment, joint stability and functional motion.
