Brief Summary
Hamstring muscle injuries are a common pathology in sports mainly present in sprint and acceleration sports, accounting for about 12% of all football injuries. Because of their frequency, risk of reinjury and financial cost, they can be considered as a public health problem. Improving knowledge of the pathophysiology of hamstring muscle injury appears to be a relevant research focus for prevention purposes.

Outcome Measures
Primary Outcomes (2)
location of the lesion of injury
Correlation between location of the lesion and mechanism of onset of injury. Location of the lesion will be measured by Magnetic Resonance Imaging (MRI) or ultrasound results. For location of the lesion, it is a combination of the injured muscle, damaged tissue and the area in the posterior compartment of the thigh.
at inclusion
mechanism of onset of injury
Correlation between location of the lesion and mechanism of onset of injury. Location of the lesion will be measured by Magnetic Resonance Imaging (MRI) or ultrasound results. Mechanism of onset of injury will be check by self-questionnaire.

Secondary Outcomes (2)
mapping of hamstring lesions

volumetric analysis of the hamstrings

Study Arms (1)
hamstring muscle lesions
Patients with hamstring muscle lesions in sport will be included. As usual practice they will have Magnetic Resonance Imaging (MRI) or ultrasound, and will answer to self-questionnaire
Interventions
Magnetic Resonance Imaging (MRI) or ultrasound will be performed to determinate location of the lesion
Magnetic Resonance Imaging (MRI) or ultrasound will be performed to determinate location of the lesion
Self-questionnaire will be completed by patient. In this questionnaire patients will describe the circumstances of the injury and their personal characteristics and level of sporting practice.
Eligibility Criteria
Athletics with thigh injury will be included.
You may qualify if:
- To be recreational sportsmen, competitions, amateurs, high-level or professional
- Aged 18 to 50 years
- Perform an Magnetic Resonance Imaging (MRI) or an ultrasound of the thigh in the context of the suspicion of an acute hamstring muscle injury
- Injury during sport since less 21 days old.
You may not qualify if:
- a history of surgery of the anterior cruciate ligament with removal of the transplant in the posterior compartment of the thigh
- an antecedent of surgery of the thigh.
- inability to understand the French language for completing the self-questionnaire
