Hello. I have undergone 2spinal fusions. Last being Jan 14 this year. Have had severe co plications w/ last one. I developed an unidentifiabl infecton that was treated over 2 months of.7 different anti biotics.It was my primary md that eventually stepped in & it healed.My concerns are I am still using a walker & am in pain I have an upcoming hip surgery. I have 2 insurances, Medicaid & United Health, but cannot afford the payments much longer. I would lke to have all hardware removed & replacedainw/ cadaver bone. With 2 cages & my md witnessing my vertebrae literally crack & see it move down to tailbone like dominoes...yes she was shocked & charted it. Other times, it feels my back is under water & is swaying side to side!!! Ruled out. Lazer I

Hi, Thanks for writing in. Your situation needs a more professional approach than taking out all the hardware inserted during surgery and replacing it with cadaver bone. The bone we have within us is a living tissue though it is hard and stronger than other tissues. This is because of calcium deposition and there is regular exchange of minerals between the bone and other tissues. The bone also gets its blood supply and remains alive. Therefore, please do not consider cadaver bone replacement for yourself. The problem with two cages and its displacement at operated site requires proper management. Back fusion surgeries might not provide a good level of pain relief in some patients. Though the pressure on nerve roots at strategic locations seems to be relieved by doing surgical procedure, the patient might often complain severe lower back pain even after surgery. This happens in about 20 to 40 percent of patients and the reason is that the affected nerve roots are still under pressure in areas other than where surgical manipulation has been done. If laser is not an option for you then please discuss new methods like radiofrequency ablation and how effective it will work for you. The problem for your extended suffering was the infection that unfortunately developed in the operated site. Now that it is cured, healing should occur fast. Wishing you the best for hip surgery.
