Hi Rob,
I could have made that clearer, I guess, but the second op. was going to be another BHR so the incision was lateral again. People on the SurfaceHippy website/forum who run have had both anterior and posterior incisions, I think posterior is easier for the surgeon but takes a bit more recovery as big muscles get cut. Some of the anterior people are discharged same day, the operation becomes outpatient with the top surgeons.
X-ray cannot show wear, merely placement and possibly movement of the implant.
Metal bearings get a chromium/cobalt blood test avery 3 years which can indicate excess wear if metal ions exceed a certain level – both are toxic in excess. My next test is due…
