Do you have a neurosurgeon or othosurgeon? What does she say about the safety of the procedure from her perspective?

There are several approaches to hip replacement: posterior, anterior and Superpath (and its variants). I wonder whether one is safer than another for your spine but I, as a layperson, have no idea. If you have a spine surgeon (I have one on call for my spinal and lumbar stenosis) ask her which approach she thinks is safest from the spine perspective. Ask her first as I would NOT recommend asking a surgeon who normally does one of these approaches to do a different one for you. Extensive experience doing the exact procedure is my #1 criteria for a hip or knee replacement surgeon.

You will also have an anesthesia choice. I am terrified of general anesthesia and my surgeon normally has his patients done with a regional (local) anesthesia choice. That is what I wanted and had. But it does involve a shot in your back so you might want to ask your back surgeon if she thinks it is safe.

For whatever it is worth, my surgeon is the primary inventor of the Superpath method and that is what he used for me five years ago. I had zero post surgical pain. The only bad side effect was the common one of not being able to reach down and pull up my socks. A couple of visits to a quality PT took care of that.

Your surgeon may be right but do your research on him. Is he almost always successful (even the best surgeon can run into unexpected problems and unexpected side effects)? Does he use the best system for your situation? If you can tolerate a local, and want one, does he regularly work under a local?

Of all the joint replacements, hip surgery is probably the safest and easiest. Just coordinate with your spine surgeon and you should be fine.
