Methods and tools for femoral resection in primary knee surgery

摘要

Femoral resection tools of the present invention include a posterior condyle alignment guide, an IM rod with an adjustable valgus bushing assembly, left and right external rotation plates, an anterior sizing boom having a stylus and a pair of medial/lateral drill guide assemblies (in one embodiment of the invention the drill guide assemblies are the combination of medial/lateral extension arms and attached (detachable) proximal positioning fixtures; in another embodiment, the proximal positioning fixtures are not part of the drill guide assembly per se), a plurality of self-tapping screws, proximal positioning fixtures (apart from any positioning fixtures that may be integrated into a drill guide assembly), and different size cutting guide blocks, each adapted to fit over the proximal positioning fixtures. Methods for utilizing the aforementioned tools so that five resections can be performed are also described.
