Abstract
A system for preparing a proximal femur can include a broach that includes a broach body having an anterior side, a posterior side, a lateral side and a medial side. The medial side can have a roughened cutting surface. The lateral side can have a smooth, non-cutting surface. The system can further comprise a cutting scribe assembly and a cutting guide assembly.
Claims22
A system for preparing a proximal femur, the system comprising:
- a broach including a broach body having an anterior side, a posterior side, a lateral side and a medial side, the medial side having a roughened cutting surface, the lateral side having a smooth, non-cutting surface.
A system for preparing a proximal femur, the system comprising:
- a broach body having an anterior side, a posterior side, a lateral side and a medial side;
- and
- a cutting scribe assembly comprising:
- an arm having a first end that includes a locating boss and a second end that includes a connecting link, the locating boss selectively locating into the locating bore of the broach body;
- and
- a cutting tool movably coupled to the connecting link, the cutting tool extending along a cutting axis that is substantially parallel to a longitudinal axis defined by the arm;
- wherein the cutting scribe assembly selectively rotates about an axis defined by the locating boss such that the cutting tool is operable to score the proximal femur to identify a desired cutting area.
A system for preparing a proximal femur, the system comprising:
- a broach body having an anterior side, a posterior side, a lateral side and a medial side;
- and
- a cutting guide assembly comprising:
- an arm having a first end that includes a locating boss and a second end that includes a connecting link, the locating boss selectively locating into the locating bore of the broach body;
- a cutting block movably coupled to the connecting link, the cutting block having cutting slots formed therein;
- and
- wherein the cutting slots include at least one cutting slot that extends in a direction substantially parallel to the longitudinal axis of the broach and another cutting slots that extends in a direction substantially transverse to the longitudinal axis of the broach.
A method for preparing a proximal femur, the method comprising:
- advancing a broach along an opening in the proximal femur, the broach having a roughened cutting surface on a medial side and a smooth non-cutting surface on a lateral side;
- removing host bone with the roughened cutting surface during the advancing;
- connecting a cutting assembly to the broach;
- marking a surface of the proximal femur with a cutting tool of the cutting assembly;
- removing the broach and cutting assembly;
- and
- cutting the proximal femur at the marked surface.
