ABSTRACT:
An apparatus for testing an implant having first and second components coupled together by an articulating ball and socket joint includes a support structure in contact with the first component of the implant for supporting said implant, an adapter coupled to the second component of the implant, and a load assembly in contact with the adapter for applying a load onto a semispherical surface of the adapter. The apparatus includes a drive assembly coupled with the adapter having a first drive shaft having a first end connected with a center of a rotatable wheel and a second drive shaft having a first end connected with an outer region of the wheel and a second end connected to the adapter. The second drive shaft has a longitudinal axis that is at an angle relative to the longitudinal axis of the first drive shaft. In operation, rotation of the first drive shaft about the longitudinal axis thereof causes articulating movement of the adapter, which in turn causes articulating movement of the first and second components of the implant under load.
