A set of provisional prosthesis instrumentation including an outer shell component, a first inner component, and a second inner component different from the first inner component. The first inner component comprises a substantially hemispherical interior surface therein, while the second inner component comprises a nonhemispherical, truncated cone or a nonhemispherical, substantially cylindrical surface therein. Either the first inner component style or the second inner component style may be selectively inserted into the shell component. The first and second inner components (inserts) are releasably connectable with the shell. The first style inner component may typically be used as a provisional for a bipolar prosthesis for a hemiarthroplasty procedure, while the second style of inner component may typically be used as a unipolar endoprosthesis provisional for a hemiarthroplasty procedure. The same style of shell component is utilized for both styles of inner components. A plurality of sizes for the shell component and for the first inner component and for the second inner component may be provided for selective utilization. The shell component may also be used in conjunction with a handle as a sizer instrument.
