Abstract

The precise restoration of a joint?s mobility after fractures can only be successful, if the original anatomical relationships are reproduced as closely as possible. Precise estimates about the morphology of the bony components are therefore of paramount importance both for reconstructive surgery by ostheosynthesis as well as for partial or total joint replacement by arthroplasty. In case of the shoulder joint, only the proper reassembly of the fragments provides sufficient information about the original anatomical relationships of a fractured humerus, due to high individual variability and lateral asymmetry. To support the precise planning of the interventions, this paper presents an enhanced environment facilitating both underlying processing steps: fragment segmentation and bone reassembly. This includes an intuitive interface for correcting preprocessed volumetric CT data as well as a visuo-haptic, virtual environment for physically-based simulation of interactive reassembly. The planning system has been successfully tested in a pilot study on four clinical cases.
