Abstract
A femoral head offset and neck length required in a femoral component to be engaged with an acetabular component are determined for establishing appropriate hip mechanics in a prosthetic hip joint. Alternate selected sleeves of different lengths are interposed between a trial femoral head component and a trial femoral stem component movable relative to one another to admit each selected sleeve, interoperatively, for serial trialing to determine an appropriate trial distance, the appropriate trial distance corresponding to the required femoral head offset and neck length in the prosthetic hip joint.
