Abstract:
1. A cap shaped, spherical implant for implantation onto a prepared stump of a femoral head, the cap shaped, spherical implant comprising: a planar base surface; an outer spherical surface region having a polar axis, said planar base surface perpendicular to said polar axis; and a hollow inner surface, said hollow inner surface being rotationally symmetric about a hollow space axis and positionable over the prepared stump, said hollow inner surface intersecting said planar base surface, and said hollow space axis intersecting said polar axis and forming a non-zero angle (α) with said polar axis, said hollow inner surface comprising a cross-section in a plane containing said hollow space axis, said cross-section of said hollow inner surface comprising a base and a pair of arms, said pair of arms extending outward from said base, one of said pair of arms intersecting said planar base surface, one other of said pair of arms intersecting said outer spherical surface region such that said pair of arms and said base define a hollow inner space therein for receiving the prepared stump of the femoral head.
