Method and apparatus for implanting a modular femoral hip

摘要

A method of implanting a prosthetic component is disclosed that includes attaching a guide rod to the prosthetic component, removably coupling the guide rod to a shaft extending from a handle, and positioning the prosthetic component in an anatomical feature. The method also includes impacting an impaction portion of the handle and uncoupling the guide rod from the shaft, leaving the guide rod attached to the prosthetic component. The method further includes positioning a reamer over the guide rod to create a reamed opening in the anatomical feature.

主权项

1. An insertion system for implanting a prosthetic component, comprising:
a handle including an impaction portion; a shaft extending from and fixed to the handle; a guide rod removably couplable to the shaft, wherein the guide rod is adapted to be rotationally fixed relative to the impaction portion and removably attached to the prosthetic component; and a coupling mechanism adapted to removably couple the guide rod to the shaft; wherein the coupling mechanism includes a sleeve that includes an inner tapered surface that engages at least one ball bearing with the guide rod when the guide rod is axially abutted against the shaft and progressively disengages the at least one ball bearing from the guide rod when the sleeve is axially retracted toward the handle.
