The doctor that did the first surgery has finally admitted something is wrong, there is a gap between the insert and the bone. This should have been fully packed with cement. When I asked what caused this his response was well sometimes these things happen. From what I have found on several medical sites is that it was not done properly, now I need a complete hip revision to take out the insert and replace it. Several hour surgery with potential complications. Plus, I will be out of work for 4 to 6 months. I have an appointment with a top revision surgeon in another city in October. I am also looking for an attorney, this failed surgery will cost me tens of thousands in medical and loss of wages, plus 2 years of severe pain and inability to do the outdoor recreation that I enjoy.
