Detailed Description:

The lateral ankle sprain is the most frequent purpose of consultation in emergency traumatology of the locomotive system.

If the ankle sprain is neglected or badly cared, it can induce a recurrence or several complications particularly functional ones. So a gravity diagnosis is necessary in order to choose the most accurate treatment.

Considering the difficulty of the clinical estimation, additional examinations aim to support the positive diagnosis, to clarify the gravity and to dismiss differential diagnosis.

Thus we suggest to evaluate three strategies in order to get a gravity diagnosis, make a better choice of treatment and so decrease the long-term functional complications : instability and recurrence.

The patients are randomly separated into three groups of 130 people. All the patients have a radiography and then, according to their group, they have either an ultrasonography or an ultrasonography and a stress radiography or only a stress radiography. The patients are followed up during two years by sending two questionnaires (CAIT and LEFS) at one and two years. The functional scores of these questionnaires assess and compare the functional complications for each group. Thus the radiologic examinations can be assessed in term of prognosis.
