Hey, I'm 19 240 lbs and 5' 8". I broke my hip when I was 12, july 3rd will be 7 years I have been dealing with the constant pain. I've had 3 surgerys 1 on july 3rd 2004 they place a screw into my femoral head, jan. 2005 removed screw due to catching of labral, and sept 9th 2010 where they did a microfracture to try to get some cartilage to grow, I had a labral tear, and bone pieces the size of marbles. I have osteonecrosis(avascular necrosis) and arthritis. Sunday 5-8-11 my hip popped completly out of place, I managed to get it back in and went and seen my surgeon on 5-10-11 he wanted xrays, which is nothing since I have had mutiple ones, but when we reviewed them I noticed blotches that were white in the abdominal region. What could this be?
