sentences:  The potential advantages of hip resurfacing compared to THR include less bone removal (bone preservation), a reduced chance of hip dislocation due to a relatively larger femoral head size (given that the patient has an anatomically correct femoral head size), and easier revision surgery for any subsequent revision to a THR device because a surgeon will have more original bone stock available.Hip resurfacing has the potential of being a solution for life, allows a normal ROM (range of movement) and minimizes the amount of "stress shielding", compared with THR.Since the femoral neck is retained and the femoral cavity with its marrow not opened up two other advantages exist, namely no risk of blood clots by fatty marrow that can enter the blood stream with the THR procedure and no risk of introducing bacteria in the opened femoral canal resulting in a deep infection as can happen with the THR procedure.
