1. A method of completing a hip arthroplasty trial on a femur comprising:
obtaining a medical device for use in said hip arthroplasty trial, the medical device comprising:
a head member, the head member having a head member first end, a head member second end, and a head member first lengthwise axis extending through the head member first end and the head member second end;
a shaft; and
a locking member;
implanting a femoral stem into said femur;
positioning the head member on the femoral stem;
moving the shaft in situ in a first direction such that the head member moves away from the femoral stem until a desired offset between the head member and the femoral stem has been achieved;
moving the shaft in situ in a second direction such that the head member moves toward the femoral stem;
obtaining a femoral head implant that corresponds to the desired offset between the head member and the femoral stem;
removing the head member from the femoral stem; and
positioning the femoral head implant on the femoral stem,
wherein the head member further comprises a first recess, a second recess, and a third recess, and wherein the method further comprises positioning the locking member within a head member third recess such that the shaft is releasably attached to the head member.
