Abstract:
1. An orthopedic guide assembly, comprising: a primary guide body having a bone contacting surface and a primary guide body opposing surface opposite said bone contacting surface, said primary guide body defining a first primary guide surface extending between said bone contacting surface and said primary guide body opposing surface, said first primary guide surface sized and shaped to guide a primary osteotome to prepare a first primary osteotomy of a bone, said first primary guide surface having a first primary guide surface extent over which the primary osteotome can be guided to prepare a full extent of the primary osteotomy of the bone, said primary guide body having a distal femoral cut guide, the distal femoral cut guide defining a posterior guide surface sized and shaped to guide one of the primary osteotome and a secondary osteotome to prepare a posterior facet of a femur to receive a posterior bone contacting surface of a femoral prosthesis thereon, the distal femoral cut guide further defining a posterior chamfer guide surface sized and shaped to guide one of the primary osteotome and the secondary osteotome to prepare a posterior chamfer facet of the femur to receive a posterior chamfer bone contacting surface of the femoral prosthesis thereon, the distal femoral cut guide further defining an anterior chamfer guide surface sized and shaped to guide one of the primary osteotome and the secondary osteotome to prepare an anterior chamfer facet of the femur to receive an anterior chamfer bone contacting surface of the femoral prosthesis thereon said s posterior guide surface defining a posterior guide surface plane, said posterior chamfer guide surface defining a posterior chamfer guide surface plane, said anterior chamfer guide surface defining an anterior chamfer guide surface plane, said posterior guide surface plane intersecting said posterior chamfer guide surface plane and said anterior chamfer guide surface plane, said posterior chamfer guide surface plane intersecting said anterior chamfer guide surface plane; and a secondary guide body having a bone-side surface and a secondary guide body opposing surface opposite said bone-side surface, said secondary guide body defining a secondary guide surface extending between said bone-side surface and said secondary guide body opposing surface, said secondary guide surface sized and shaped to guide a selected one of the primary osteotome and the secondary osteotome to prepare a secondary osteotomy of the bone, said secondary guide body rotatably connected to said primary guide body, said secondary guide body rotatable from an operative position in which said secondary guide is operably positioned to guide preparation of the secondary osteotomy to a non-operative position in which said secondary guide is not capable of guiding preparation of the secondary osteotomy, in said operative position said secondary guide body presents a barrier to movement of the primary osteotome guided by said first primary guide surface so that movement of the primary osteotome is restricted to less than movement over a full extent of the first primary guide surface extent when said secondary guide body maintains said operative position, in said non-operative position said secondary guide body does not present the barrier to movement of the primary osteotome guided by said first primary guide surface to less than movement over the full extent of the first primary guide surface extent, said first primary guide surface extent fully accessible by the primary osteotome to prepare the full extent of the primary osteotomy of the bone when said secondary guide body maintains said non-operative position and said first primary guide surface extent is not fully accessible by the primary osteotome to prepare the full extent of the primary osteotomy of the bone when said secondary guide body maintains said operative position.
