Outcomes

Primary Outcomes

Diagnostic performance rate of anatomical lesions of the ankle of ultrasound

Sensitivity of ankle ultrasound compared to MRI, considered as a gold standard, in the diagnosis of traumatic ankle injuries

Time frame: Baseline (inclusion)

Secondary Outcomes

Diagnostic performance rate of anatomical lesions

Specificity, predictive values (positive and negative) and likelihood ratios (positive and negative) of ultrasound versus MRI

Time frame: Baseline (inclusion) and at visit 2 (within 7 days after the baseline)

The use of Ottawa decision rule

the place of Ottawa criteria and ultrasound in the decision algorithm to limit standard radiographs (and thus irradiation). The Ottawa Ankle Rule was derived to aid in the efficient use of radiography in acute ankle and midfoot injuries.

Time frame: baseline (inclusion)

orthopedic rehabilitation quality at 3 weeks according to the Oxford score.

The Oxford Ankle Foot Questionnaire for Children (OxAFQ-C) is used to measure subjective well-being for child patients (aged 5-16) affected by foot and ankle conditions using issues that are considered important to children. The OxAFQ-C has 15 items, 14 of which are used to calculate domain scores: Physical (6 items); School and Play (4 items) Emotional (4 items)

Time frame: at 3 weeks (control visit)
