(54) Title: FEMORAL BASE PLATE THA 
(57) Abstract: A method of creating a mass-customized 
femoral bone base plate comprising: (i) establishing anatom
ical landmarks across a plurality of bone models of a statist
ical atlas; (ii) establishing instrument landmarks across the 
plurality of bone models of the statistical atlas; (iii) establish
240 ing definitions for a reference plane calculation across the 
plurality of bone models of the statistical atlas, where the ref
erence plane represents a boundary of a prosthetic implant; 
252 (iv) establishing an attachment site for a mass-customized 
250 femoral bone base plate using the anatomical landmarks, the 
instrument landmarks, and the reference plane; and, (v) fab
ricating the mass-customized femoral bone base plate con
234 figured to be attached to a femur, where the attachment sites 
of the mass-customized femoral bone base plate are predeter
230 mined to avoid impingement with the prosthetic implant 
when implanted.
