Imaging Location of Hamstring Muscle Lesions in Sport and Relationships With Injury Mechanism.

Terminated

• Conditions: Sport Injury; Hamstring Muscle Lesions
• Interventions: Other: Magnetic Resonance Imaging (MRI); Other: ultrasound; Other: Self-questionnaire

• Registration Number: NCT03373084
• Lead Sponsor: Centre Hospitalier Universitaire de Saint Etienne

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.

Detailed Description

This study is a cohort of athletes in the context of suspicion of hamstring muscle injuries.

Arm && Interventions

Group	Intervention	Description
hamstring muscle lesions	Magnetic Resonance Imaging (MRI)	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
hamstring muscle lesions	ultrasound	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
hamstring muscle lesions	Self-questionnaire	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

Primary Outcome Measures

Name	Time	Method
location of the lesion of injury	at inclusion	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.
mechanism of onset of injury	at inclusion	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 Outcome Measures

Name	Time	Method
volumetric analysis of the hamstrings	at inclusion	A standardization of the images to allow a better comparison between individuals
mapping of hamstring lesions	at inclusion	Analyzed of mapping of hamstring lesions with Magnetic Resonance Imaging (MRI) / ultrasound.; Compare the MRI and ultrasound maps and the performance of the two means to determine the location of the lesion.
