It is an uncemented stem, with hydroxyapatite coating which encourages rapid bone growth into the prosthesis. It is anchored in the femoral neck (as opposed to the femoral shaft as in conventional hip replacement) so will feel more natural for the patient than a conventional prosthesis. Also the anchoring in the femoral neck means that recreation of the patient’s specific anatomy is much more accurate, meaning stability and range of motion are optimised and personal to the patient. Further benefits of the component being anchored in the femoral neck are that it requires less bone removal to implant it. It is also more sparing of the important soft tissues around the hip joint meaning earlier return to function and again more natural feeling of the implant. Anatomically it will behave more like a resurfacing arthroplasty without the significant risks of having a ‘metal on metal’ implant.
Further benefits of leaving more bone during the primary operation means that in the unlikely event that the prosthesis needs removing or changing many years down the line the revision less destructive and the reconstruction can therefore be more like a primary hip replacement than a revision.
".... I came around after Mr Edmondsons surgery having felt nor heard a thing that had transpired during the operation, I was then given a cup of tea and wheeled back to my room. 2h later I was gingerly using my crutches to transfer from my bed to the washroom. 4h later I heard footsteps coming into the room and the familiar sound of a crash helmet being placed on the floor it was Mr Edmondson who had come to check on me before he went home. Conversation soon got round to a mutual passion for motorcycling, something that I had been experiencing difficulty with due to the pain and restricted movement in my hip. I stayed the next day in Hospital and was discharged the following morning, I managed to convey myself on crutches into the car and home, time to reflect upon the dilemma of which was to be the more painful, the hip or the prospect of being driven by members of my family.
I had suffered for quite sometime with pain and restricted movement. Had I known the reality of hip replacement surgery then I would have done it a lot sooner. Now a year on I am enjoying playing cricket and my motorcycle and that as they say is "priceless".
As for Mr Edmondson he is down home, approachable and from my experience a brilliant surgeon who has earned my eternal gratitude."
