Ask the Doctors
A few centres have reported a phenomenon, which has been named ‘pseudotumors’ by a renowned orthopaedic hospital in Oxford. The term pseudotumor refers to a problem
One of my patients from India who has had a resurfacing, briefed me on the current discussion in the surfachippy forum regarding Dr. Klappers opinion of losing acetabular bone in an attempt to preserve femoral head bone in resurfacing.
When I stand with feet together then bend my legs with knees together the distance that my right knee cap extends is about 2 inches longer (more protruded) than my left.
Dr Carome has not responded to or acknowledged my e-mail dated 16th April 2012 (see below) despite further e-mail communication being sent to both himself and his secretary.
Here is a video of a patient that celebrated 20 years with his first metal on metal hip resurfacing.
In short, his concerns only underline the fact that bad results of resurfacing are due to badly done resurfacings. The head neck ratio is an important determinant of range of movement and prevention of impingement. In a patient with normal anatomy, if one is careful to restore anatomy the range will be like pre-0p range of movement before the onset of arthritis. This is a simple concept.
Can you please give me your opinion on the new Direct Anterior approach, not the anterolateral approach but the DIRECT anterior approach. A couple of doctors have started using this and I want to get some feedback from the top doctors on it.
In a patient who does not have limb length discrepancy, one resects to the thickness of the component (femoral head) that we are going to use. For example if the thickness is x mms then we resect x mms of bone from the top of the head.
The ganz trochanteric flip is an excellent approach for doing open FAI surgery, for fixing fracture on the femoral head ( pipkin #) and for doing osteotomy of the femoral neck in post SUFE situations. In these non - arthritic situations a surgical dislocation of the hip is warranted without damaging the blood supply and I employ it routinely for these indications.
If a patient has a revision due to high metal ion levels, how long before the metal levels start to return to normal after a patient gets their hip resurfacing revised? And if they don't return to normal, what should a patient do?
