Has anyone had fusion hardware removed? Hubby has a screw out of place and a rod unattached. We are not sure if this is causing his increasing pain and inability to stand for a few minutes or to walk (like from the house to the mailbox). His fusion was in 2007--L4-L5. He has had a failed spinal stimulator (broken leads and migrating generator) and has tried many things for pain--prolotherapy, laser, shock wave. Nothing helps. Is currently trying acupuncture. We are curious about removal of hardware with subsequernt improvement in pain.
