Thanks all for the leads. My daughter is 18. Was diagnosed with Acute Lymphoblastic Leukemia at 16. She is nearing the end of her treatment, thankfully. But she has had multiple serious complications as a result of treatment which is, sadly, too often the case.
About a year ago was diagnosed with AVN (Avascular necrosis) bilateral hips, knees, and ankles as a result of the high-dose steroids as part of the ALL protocol.
She had a core decompression done on her right side last December (hip, knee, ankle) which - at least with regards to the hip - was not successful. Both hips are now in the process of collapse so we are looking at likely having both hips replaced within the relatively near-term future.
