INTRAMEDULLARY BASED AND OMNI-POSITIONABLE CUTTING GUIDE INSTRUMENTATION FOR FEMORAL EPIPHYSIS RESECTION FOR KNEE PROSTHESIS PLACEMENT AND A METHOD OF OPERATION THEREOF
An intramedullary based &； omni-positionable cutting guide instrumentation for femoral epiphysis resection for knee prosthesis placement comprising: an intramedullary placement guide (1,27) in a medullary cavity of a femoral epiphysis having an anterior/posterior adjustment mechanism (33)； posterior rotational referencing sizing jig (8) for fastening to the anterior/posterior adjustment mechanism (33) and configured for referencing anterior (10) and posterior (11, 18) surfaces of the femoral epiphysis to adjust the anterior/posterior offset of the anterior/posterior adjustment mechanism (33)； and a punch card (20) for subsequent fastening to the anterior/posterior adjustment mechanism (33) and comprising a plurality of position referencing apertures (21a-21d) for receipt of at least one locking pin (23) of a cutting block guide (5) to allow the anterior/posterior positioning of the cutting block guide (5) at a first position (e.g. FIG. 10) for making a first resection (e.g. 24) and at a second position (e.g. FIG. 11) for the purposes of making a second resection (e.g. 37).
