| 摘要 |
A total hip joint prosthesis including an acetabular cup implant of a construction permitting an initial adjustable disposition for optimum articulation with a prosthetic femoral ball mounted on a femoral prosthesis within a usual cup implant, the implant is of a trapezoidal or truncated cone shape, and external fins and a porous surface are provided to facilitate an initial and long-term positional fixation in the user, and to compensate for physiological bone changes over an extended period of time. The porous surface is preferred but an option is to use a plain surface implant used as a "press-fitted" device.
