Head Neck Ratio in Hip Resurfacing by Dr. Vijay Bose
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.

Leg Lengthening by Dr. Vijay Bose
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.
