Cervical spine fusion hardware failure
Hello my mother had multi level spinal fusion. About eight months after her rods cracked then broke. The surgeon used a local bone autograft with allograft chips. From what he said the graft did not take and that is what caused the rods to break. She had to have another surgery to remove the hardware and this time they used a bone from her hip for the bone graft. I guess what i am trying to figure out is if it is normal for the rods to break in under ten months if the graft does not take , or how long does a normal fusion take to work. Any help would be great.
