Summary.

Relative shortening of the fibula may occur after any type of ankle fracture when the lateral malleolus is involved. Patients complain of pain and restriction of their daily and sporting activities. Clinically, there is valgus of the hind foot due to abduction and lateral rotation of the talus. The goal of treatment is to restore the initial length of the fibula by a horizontal or Z-osteotomy, which will also correct the malposition of the talus. This study shows that the operative reconstruction of a widened mortise is a relatively safe procedure, independent of the type of osteotomy used. Lengthening of the fibula is an important step in the treatment of the painful ankle when the fibula is short after trauma, even when degenerative changes of the joint are already present.

Resumé.

Nous avons analysé six cas de raccourcissement posttraumatique du péroné. Differents types de fracture et de traitement ont menés à cette situation, qui, cliniquement se caracterise par des douleurs au niveau de la cheville et une déviation en valgus et rotation externe du pied. Tous les péronés ont été corrigés par des osteotomies d’allongement (ORP), soit horizontalement ou en forme de ”z”. Nos résultats montrent que la réconstruction opératoire d’une mortaise élargie constitute une intervention relativement simple qui donne de bon résultats et qui peu ralentir ou même arrêter la progression d’une arthrose posttraumatique. En conséquence l’ORP devrait constituer le traitement de choix dans les cas de raccourcissement posttraumatique même si des signes de dégénerescence arthrosique sont présents.
