title: [Additional supra-malleolar osteotomy].
abstract: This old operation is rarely practiced and it appeared interesting to precise its technique and indications from a short series. In the majority of our cases, a valgus type osteotomy by medial graft addition was performed. One or more prismatic triangular graft are taken from the full thickness of the iliac crest. The respect of the fibula protects the periostal hinge on the other side of the surgical approach; so the graft under pressure will have rapid and constant consolidation. Tibial osteosynthesis is facultative. We can distinguish major indications of that type of osteotomies: supramalleolar malunion, while the fracture of the fibula associated to the tibia is a contra-indication for that operation. The other indications are the distortion of the pilon articular surface and old ligamentous lesions leading to osteoarthritis. In some cases, it is appropriate to realise valgisation of the articular surface, with an overcorrection to harmonise the pressure on articular surfaces; on that condition, an osteotomy of the fibula has to be discussed. The rapid and constant good results obtained with those iliac crest grafts interposed between the two fragments of the tibia contrast with those hazardous results of inlay or onlay grafts, free from all mecanical sollicitations.
