What should i expect when i have a mra done to confirm 2 labral tears, superior & posterior, on my l hip as on a mri?

Step by step: Conservative treatments such as rehab, medications, supplements first...When symptoms progress to limiting pain - particularly night pain that interrupts sleep - and stiffness that cannot be controlled with anti-inflammatory medications, as well as difficulty engaging in everyday activities, a total hip replacement (or, in some cases, a hip resurfacing procedure) should be considered...

See below: I believe you are referrring to MRI with direct athrography of the hip. This is typically done with injection of an MRI dye (gadolinium) into the hip joint prior to the mri. This is a minor invasive procedure, using a needle. The doctor typically gives you a local anesthetic for this. A small amount of ct contrast is also injected for the needle placement. The doctor would explain risks & benefits.
