A fusion surgery is in the near future for my wife on her L5/L4. She has had 2 previous surgeries for the same disc and it herniated within 10 days after her last discectomy this past June confirmed via MRI. She had mild pain up until 3 weeks ago and now the pain level has increased dramatically and numbness too.
The neurosurgeon we consulted back in August mentioned doing an MIS TLIF when and if it is needed. He advised waiting and trying more PT as well as letting pain level dictate. He has about 20 years experience, Chief NS at the hospital, and has also recently done research for DDD using flexible fusions (not applicable). He also works on the brain, developed a technique called the Gamma Knife for brain surgery earlier in his career, so he is very well rounded. My online research of his work has shown people are very happy with his work, be it brain surgery or back surgery and even the pain medical doctor (in the practice) said she would go to him if needing the fusion.
During that consult a few months back in regards to the MIS TLIF, he mentioned only placing one rod and one set of screws. I asked and he said that one was all that is needed, but he would put two in if we wanted. My wife does have a good amount of scar tissue so maybe that was the determining factor? In researching the procedure, I haven't come across only a single rod being used. Is this something new, has anyone on here heard of this before?
