Modular femoral provisional

A modular provisional system comprising:

• a frame component configured to be secured to a distal end of a resected femur to provide a support surface, including a first substantially planar condylar base and a second substantially planar condylar base connected by an anterior bridge portion connecting anterior proximal portions of the first and second condylar bases and configured to abut an anterior femoral resection of the resected femur, and a posterior bridge portion connecting posterior proximal portions of the first and second condylar bases;
• wherein the anterior bridge portion including a plurality of engagement structures, the frame component including bone contacting surfaces configured to contact the distal end of the resected femur on three separate planes formed by resected surfaces including a distal resection, the anterior femoral resection and posterior femoral resection;
• and
• a plurality of shell components, each of said plurality of shell components configured to be releaseably secured to said support surface of said frame component by the plurality of engagement structures, said frame component and each of said plurality of shell components cooperable to form different provisional implants each of which replicate the characteristics of at least one nonprovisional component of a prosthesis system, different ones of said plurality of shell components releasably securable to the resected femur via the support surface of the frame component when the frame component is secured to the distal end of the resected femur.
