A trial implant kit includes a plurality of intermediate components and a plurality of inner components. Each of the plurality of intermediate components has a uniform inner surface, although at least two of the plurality of intermediate components having distinct outer surfaces. Each of the distinct outer surfaces is configured to engage one of a plurality of acetabular shell component geometries. Each of the plurality of inner components has a uniform outer surface portion and a bearing surface, the uniform outer surface portion configured to be received by the uniform inner surface of any of plurality of intermediate components. The bearing surface is configured to engage a femoral head. At least two of plurality of inner components having distinct bearing surface configurations.

A surgical instrument support system has a support frame supported by three arms. Each arm has a plurality of ball and socket members strung in series along a cable. The arms are also connected to bases mountable to the patient's limb on the proximal and distal sides of the joint. Actuators are provided for each arm to change the tension in the cables to change the stiffness of each arm. The support system can be part of a surgical instrument system that includes a plurality of resection guides mountable to the support frame.
