Hi
Welcome to Hip Talk.
It is not possible for someone to tell you when a doctor will tell you it's time to have a resurfacing. We are not medically trained. There are many issues a surgeon will consider including the information he sees from your x-ray, your bone density, your pain and your activity level. There are so many things that an untrained person could not tell you.
You really need an experienced surgeon to look at your x-rays and tell you if you are a candidate. I don't know any experinced hip resurfacing surgeon that would do either a resurfacing or THR if they felt it was not time to do the surgery. They are all VERY busy and are not looking for business. The top surgeons have people waiting for months for surgeries. You can also wait too long and miss the window of opportunity for resurfacing if your hip deteriorates too long. Your pain level is not the only indicator of your hip deterioration. Some people have a great deal of pain and not much deterioration, while others have a higher tolerance to pain and have very deteriorated hips. Only an x-ray can tell a surgoen what shape your hip is in.
Some people have had shots of steroids into the hip capsules that can help for a month to many months. Doctors will usually only give those a couple times because the steroids destroy cartileage. Pt can help build muscle, but can never regrow cartilage. So sometimes PT can help, but it will not stop hip deterioration. There is nothing available yet short of replacing a deteriorated hip. Surgeons will generally try all non-surgical methods first inculding meds and shots into the hip capsule. After that, there are not any other options available if you want to be out of pain and active.
Again, there is no diffeence between a THR or resurfacing if you are in pain and inactive. Both will resolve the probelm. Both are very major surgery. Resurfacing, however, allows you to keep a large part of your femur bone and generally gives you a more natural gait. That is why the people here have choosen resurfacings.
51 is not that young to require a resurfacing or THR. Your hip condition determines that you need a hip replacement - not your age. I have stories posted of teenagers and people in their twenties that have had hip resurfacing. Hip problems occure reguardless of your age.
So the answer is once again, choose a really expeirnced hip resurfacing surgeon from my list and get input from a professional.
http://www.surfacehippy.info/listofdoctors.php Only an experinced surgeon can tell you what shape your hip is actually in. If you choose less expeirnced surgeons and those that don't do resurfacing - they will suggest THRs. If your case is diffiuclt, the less experinced surgeons will also often opt for a THR. Choose a surgeon that has done 500 or better a thousand or more resurfacings. Normally they are not in your home town, you have to travel. You only have 2 hips and need the best surgeon available to make sure they work right after surgery.
Good Luck.
