8 months ago I had spinal surgery to fuse L2 - L5. Yesterday I visited the orthopaedic surgeon who advised me that the bone graft has not taken. I take meds to enhance bone growth and started looking for another reason as to how this could be. Note - I am battling to walk an d have constant pain as the screws are loose due to the bone not having grafted. I found on the internet that the drug ivaroxaban can inhibit bone growth. This ingredient is found in blood thinners which I take permanently. Has anyone heard of this before or have you perhaps had a similar experience? I am really depressed about this as my life's quality has been very adversely affected. We are keen caravanners and obviously this has also been negatively impacted.
