Fracture mapping Assessment of fracture characteristics from AP to 3D

The use of digital imaging techniques enables more advanced assessment (i.e., qualitative and quantitative analysis) of fracture characteristics and therefore improve our understanding of fracture morphology. In addition to accurate characterization of fractures, classification systems must include reliable fracture characteristics in order to be useful. This thesis contributes to improvement of assessment of fracture characteristics, included in classification systems or not, its reliability and use in clinical practice. We showed that fracture mapping techniques help increase knowledge of fracture line patterns and distribution, and zones of comminution. Qualitative assessment of fracture characteristics using fracture maps has proved a useful method for validating current (or new) fracture classification systems.
In addition, quantitative assessment using 3DCT techniques enable to determine specific fracture characteristics (e.g., fragment size, shape, and articular involvement) and can be used to predict fragment fixation. Furthermore, in an effort to improve interobserver reliability for characterization of fractures, we studied the effect of adding 3DCT reconstructions to 2DCT-based evaluation, simplifying classifications systems, and training on agreement between orthopedic surgeons.
