[Lateral peritalar luxation: prognostic evaluation and therapeutic approach. Review of the literature based on a clinical case].

The incidence of the peritalar dislocations has been estimated to be approximately 1% of all dislocations. If they are missed, the consequences are serious and lead to an important surgery of the hindfoot. Lateral dislocation is most rare than medial dislocation. The diagnosis of this lesion often requires X-rays of the foot. The CT-scan allows to confirm the diagnosis and to appreciate the associated intra-articular fracture. The reduction must be realized in urgency under anaesthesia. If the orthopaedic reduction is impossible, the surgery allows to obtain an anatomical reduction with the removal of obstacles and the fixation of the associated intra-articular fractures. The prognosis of this lesion is better if there is an appropriate and rapid treatment.
