Design outcomes

Measure	Time frame

Secondary

Measure	Time frame
With the Fitmore stem, so-called "overstuffing" occurs more often, in which the original shaft does not sink into the bone as deep as the shaft rasp. Intraoperative measurement of the leg length with the shaft rasp and with the original shaft.	—
