Thanks Ned & Simon for the info.
It's pretty impressive what the docs can do with an MRI + key hole surgery these days. I'm having a bit of re- shaping to the ball joint, along with a repair to a laberal tear, socket parts have cracked which will be removed and drilling to encourage the bone marrow to fight a bit of arthritis.
Due to the Christchurch Earth quakes over the past 9 months, my operation dates have been moved three times, which is understandable.... although very frustrating. After the shakes to the hospital this past week, it sounds like I'll be postponed a 4th time due to lack of running water at the hospital, along with the power source being via generator, no sewage and the entrances are a little bumpy to say the least. Might be time to take a rain check and scamper to a warm climate
