Interest of Ultrasound in the Diagnosis of Severity of Lateral Ankle Sprain

Interest of Ultrasound in the Diagnosis of Severity of Lateral Ankle Sprain

Ankle sprain is a frequent and widely trivialized trauma. Misdiagnosed or poorly treated, it can recur and thus develop into chronic ankle instability. It can be associated with complications which, if not detected early, can lead to long-term sequelae.

The hypothesis of this study is that ultrasound can better characterize the severity stages of the sprain and can diagnose complications that may have gone unnoticed on physical examination.

Patients were assessed clinically: demographics, history, clinical examination, functional scores. An ultrasound and an MRI were done during the first month to check for complications. The main objective is to assess the value of ultrasound in the diagnosis of the severity of the lateral ankle sprain. The secondary objective is to compare an ultrasound assessment of severity with a clinical assessment and Magnetic Resonance Imaging (MRI).

Inclusion Criteria:

• First ankle sprain with sport or work disability

Exclusion Criteria:

• Patient with fractures, dislocation or hyperlaxity
• Previous ankle sprain
