Description of intervention(s) / exposure
Healthy volunteers who have no hip pain will undergo one magnetic resonance imaging (MRI), to see the prevalence of asymptomatic hip acetabular labral tears. Each MRI scan will take approximately 20 minutes.

Outcomes
Primary outcome [1] 287187 0
Identifying incidence of hip acetabular labral tears using magnetic resonance imaging
Timepoint [1] 287187 0
Within one year of selecting volunteers. (volunteers will get their magnetic resonance imaging at various times throughout the year)
Secondary outcome [1] 297578 0
Incidence of hip pain in those volunteers where acetabular labral tear was identified. This will be done using a modified Harris Hip Score that is to be incooporated into a standardized questionnaire.
Timepoint [1] 297578 0
Participants with labral tears will be contacted yearly. We anticipate we will produce a summary of the obtained results in a follow up study at 5 and 10 years after the magnetic resonance imaging was performed
Secondary outcome [2] 297589 0
This is in regards to those participants who have labral tears, and develops symptoms from it. We will study if there are any associations between developing a symptomatic labral tear and any of the demographic details (obtained prior to the MRI scanning). The demographic details are weight, ethnicity, smoking habit, amount and duration of regular sports/recreational activities
Timepoint [2] 297589 0
This subset of participants will be followed up yearly as explained in 'secondary outcome 1'. When all data are available, we will be performing statistical calculations for our follow up studies to see if there are any significant associations. This will occur at 5 and 10 years after the MRI scan.
