Hi Mary
Welcome to Hip Talk.
Most people that have resurfacing have cysts. Only a surgeon can decide if the size or placement will prevent resurfacing. That is one good reason to consult with an experienced hip resurfacing surgeon to find out how bad your hip is. The x-rays will tell the surgoen what he/she needs to know. It is possible to wait too long and the hip will become too deteriorated to have a resurfacing.
You did not say how old you are. We are all very pro resurfacing here. I was 61 when I had my resurfacing and felt I was still way to young to have a THR and have my femur bone cut off to pound the long stem of a THR device into it. Resurfacing is bone conserving and gives you a more natural gait than a THR. You can see the hundreds of stories how active people are after resurfacing on my website.
If you are in the decision making process, please take time to do some reading on my website before letting a local orthopedic sell you on a THR. If you look above to the heading, you can see a list of informative articles to get you started.
Surgeons that don't do resurfacing will not recommend it, so most orthopedic surgeons will not be recommending Resurfacing for you. You will have to do some research to find an expeirnced surgeon near you to get a consultation. The top surgeons will often give free email consultations if you write to them and attach your x-rays in a digital format as a .jpg file. You can see my list of surgeons for the really experienced surgeons. Check out the doctors that have done more than 500 resurfacings and better yet - more than 1000 resurfacings.
Good Luck.
