Problem: The painful shoulder is a very frequent clinical problem which has a significant socio-economic impact. A better understanding of the biomechanics of this articulation is essential on a diagnostic level and in terms of quantifying the effects of an intervention. A variety of medical imaging techniques are now available which allow the bony structures of the shoulder to be visualized. Magnetic Resonance Imagery enables a 3D scanning of the shoulder bone complex and a recovery of exact data concerning the shape and relative position of the anatomical structures of interest.
Approach: The research project proposed aims to develop new 3D techniques of morphological analysis applied to the study of the shoulder bone complex. The results of this analysis will enable a statistical investigation of the normal and pathological morphological variability of this anatomical structure. This investigation will involve the extraction of the geometrical characteristics of the shoulder. The models which are generated will be used in the classification phase. The goal of the classification is to find a robust method of discriminating between asymptomatic and pathological shoulders. The proposed project opens a new research avenue, integrating morphological analysis for the statistical modeling of complex anatomical structures. The research will address both the modeling of individual components of the shoulder articulation as well as study their geometry and relative position.

The database associated with the project consists of a sequence of MRI images acquired in vivo on human shoulders.
