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

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
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).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Severity score by ultrasound (US) assesment | Collected in medical record. This system utilises a classification that is based on injury severity related to the amount of tissue damage and associated functional loss. It categorises muscle injuries into three grades, ranging from grade 1 with no appreciable tissue tear, grade 2 with tissue damage and reduced strength of the musculotendinous unit and grade 3 with complete tear of musculotendinous unit and complete loss of function | Day: 14 after Ankle Sprain. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Severity score by Magnetic Resonance Imaging (MRI) assesment | Collected in medical record. This system utilises a classification that is based on injury severity related to the amount of tissue damage and associated functional loss. It categorises muscle injuries into three grades, ranging from grade 1 with no appreciable tissue tear, grade 2 with tissue damage and reduced strength of the musculotendinous unit and grade 3 with complete tear of musculotendinous unit and complete loss of function | Day: 14 after Ankle Sprain. | 
| Severity score by radiologist assesment | Collected in medical record. Empirical score : low, mild, severe | Day: 30, 90, 180, 365 after Ankle Sprain. |
