Characterizing scaphoid nonunion deformity using 2-D and 3-D imaging techniques

Scaphoid fractures in the carpal wrist are notorious for their relatively high rate (5‒10%) of failure of fracture healing, resulting in a so-called nonunion. Nonunions are associated with a typical humpback deformity resulting in a malalignment of the scaphoid fragments. Anatomical reconstruction of such a nonunion is challenging in the absence of a reliable way to quantify the deformity. This thesis contributes to the development of advanced 3-D CT-based imaging techniques, to improve the quantification of scaphoid nonunion deformity and the associated level of carpal osteoarthritis. These techniques may improve surgical management of scaphoid nonunions.
