Anatomical landmarks position estimation in incomplete 3D humerus models

Manuela Calderone, Andrea Cereatti, Emilio Merella, and Ugo Della Croce

June 2012

Abstract

A general method for estimating the anatomical landmarks location on incomplete 3D bone model was proposed in order to use standardized anatomical frame conventions. An estimate of the location of missing anatomical landmarks was obtained by matching the incomplete bone model under analysis to a template of a complete bone model on which anatomical landmarks have been previously identified. The methodology was tested on three humeri. Results have shown that while the method provided reliable results when the models of the bone portion and of the complete bone belonged to the same subject, errors highly increased (up to 19 deg) when bone meshes, relative to different subjects, were used.
