Orthopaedic surgery planning

A computer-implemented method of planning orthopaedic surgery, comprising:

• providing a library of templates representing orthopaedic implants;
• displaying first and second patient images showing anatomical features that are relevant for the orthopaedic surgery being planned;
• scaling the first and second patient images according to user input;
• displaying over the first patient image a first view of a geometrical construct, the geometrical construct comprising a plurality of interrelated shapes and lines being defined by a plurality of geometric parameters interrelated in three dimensions, the geometric parameters corresponding to parameters describing the orthopaedic prostheses represented by the templates in the library;
• displaying over the second patient image a second view of the geometrical construct;
• allowing a user to reconfigure the geometrical construct according to the anatomical features of the underlying patient images so as to specify a mapping of the bone structure shown in the first and second patient images, by adjusting geometric parameters adjustable in the first and second views;
• and
• automatically selecting at least one template from the library in accordance with the geometric parameters adjusted by the user.
