The hip stem is categorized into PBG Cementless Hip Stem andCemented hip Stems. The head of the hip stem is designed with a Morsetaper, with an additional microwave pattern surface design for a morestable fit, and a flat neck design for increased hip mobility.The PBG Cementless Hip Stem is made of Ti6Al4V. The body of the hipstem is implanted into the medullary cavity and is available in differentshank shapes to meet different medullary cavity morphologies and tosupport and fill the medullary cavity.The cemented hip stem is made of Co-Cr-Mo Alloy. The stem has adouble-taper design to prevent the prosthesis from sinking, and thesurface is highly polished with a relatively rough surface design, whichreduces the risk of accelerated wear and loosening due to loosening ofparticles on the surface of the femoral stem.
