My daughter has osteoporosius and after badly fracturing her back she had first 1 spinal fusion, then another 4 years ago. She had limited options because the break was so complex and she could have ended up in a wheelchair. The pedicle screws started coming out almost immmediately and she is in terrible pain. You can actually see 2 of the screws protruding from her back and she is getting wound care for it every 2 days. She had a bad experience with her orthopedic surgeon but no other doctors want to get involved. She has other health issues and it would be dangerous to have the hardware removed. Apparently scres coming loose is not uncommon, expecially with someone who has osteoporosus. As others have said, it is an individual choice but explore all options. Good luck.
