摘要: Abstract The wear behaviour of a new dual mobility total hip design was compared with that modular using the 12-station anatomic joint simulator HUT-4. In addition, two positions acetabular shells were compared, at 45° and 60° abduction. insert material conventional ultra-high molecular weight polyethylene (UHMWPE) in both designs, femoral head stainless steel. differences mean rates between designs either position, not statistically significant. order 20 mg per one million cycles.
