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

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.

Cohorts and Interventions

Group / Cohort

Intervention / Treatment

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

Other: Magnetic Resonance Imaging (MRI); Magnetic Resonance Imaging (MRI) or ultrasound will be performed to determinate location of the lesion; Other: ultrasound; Magnetic Resonance Imaging (MRI) or ultrasound will be performed to determinate location of the lesion; Other: Self-questionnaire; 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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.	at inclusion

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
mapping of hamstring lesions	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.	at inclusion
volumetric analysis of the hamstrings	A standardization of the images to allow a better comparison between individuals	at inclusion
