SUMMARY OF THE INVENTION [0006] The present invention seeks to provide improved joint implants and methods relating to joint implantation. [0007] The present invention seeks to provide improved joint implants and methods relating to joint implantation. [0008] There is thus provided in accordance with a preferred embodiment of the present invention an implantable artificial socket for a joint formed by molding of polyurethane. [0009] There is also provided in accordance with a preferred embodiment of the present invention a unitary implantable artificial socket for a joint formed of a resilient material. [0010] There is further provided in accordance with a preferred embodiment of the present invention an implantable artificial socket for a joint and including a one-piece resilient element which is snap-fit engageable with a bone and which defines a wear resistant articulation surface. [0011] There is also provided in accordance with another preferred embodiment of the present invention a manufacturing method for an implantable artificial socket for a joint including forming the socket by molding of polyurethane. [0012] Further in accordance with a preferred embodiment of the present invention the implantable artificial socket for a joint is generally of uniform thickness. [0013] Typically, the implantable artificial socket is symmetric about an axis of rotation. [0014] Preferably, the implantable artificial socket includes a hemispherical concave inner articulation surface. [0015] Preferably, the hemispherical concave inner articulation surface has a beveled edge. [0016] Still further in accordance with a preferred embodiment of the present invention the implantable socket for a joint includes a generally hemispherical outer bone engagement surface. [0017] Additionally in accordance with a preferred embodiment of the present invention the generally hemispherical outer bone engagement surface has formed thereon, at a location between an apex and a rim thereof, a generally annular outwardly extending protrusion. [0018] Further in accordance with a preferred embodiment of the present invention the generally annular outwardly extending protrusion defines a generally annular undercut. [0019] Typically, the generally annular outwardly extending protrusion is a generally peripheral protrusion. [0020] Further in accordance with a preferred embodiment of the present invention the generally annular outwardly extending protrusion is arranged for snap-fit engagement with a corresponding groove formed by reaming of a bone.
