Method and apparatus for segmental bone replacement

A hip attachment assembly for attaching within a cavity formed in a femur, said hip attachment assembly comprising:

• a main body having a convex articular portion and a substantially concave interface surface operable to engage a surface of a proximal femoral head that has been shaped to a generally convex configuration, said main body further having a sleeve extending from said interface surface, said main body being formed from a single member;
• an anchor operable to be fully retained within the cavity formed in the femur to anchor said hip attachment assembly to the femur, said anchor including a mating member operable to be slidably engaged with said sleeve and an attachment mechanism located within the cavity and operable to fixedly attach said anchor within the cavity formed within the femur;
• and
• a compliant portion operable to be expanded and contracted, said compliant portion disposed and contained within said sleeve and operatively associated with said main body and said anchor, wherein upon slidably engaging said sleeve with said mating member, said sleeve substantially inhibits non-axial deflection of said compliant portion.
