摘要：
An acetabular trialing system has a trial cup including a body comprising an outer surface, a part-spherical inner surface and a rim extending between the inner and outer surface with a plurality of spaced inwardly resiliently deflectable rim members each connected at a first end to the body outer surface. The part-spherical inner surface has a plurality of spaced resilient deflectable bearing members each forming part of the body part-spherical inner surface. The bearing members have a first end deflectable towards the body outer surface. Upon inward deflection, one of the plurality of deflectable rim members is capable of contacting the first end of a corresponding one of the plurality of deflectable bearing members and moving the bearing member towards the body outer surface and into contact an electrical signaling device mounted on the body intermediate the outer surface thereof and the deflectable bearing member.
