| contents | While computational modeling may help to develop new treatment options for hand and wrist injuries, at present, few models exist. The time and expertise required to develop and use these models is considerable. Moreover, most do not allow for variation of material properties, instead relying on literature reported averages. We have developed a novel automated workflow combining non-linear morphing techniques with various algorithmic techniques to create participant-specific finite element models. Using this workflow, three participant-specific models were created from our existing four-dimensional computed tomography (4DCT) data. These were then used to perform two analyses to demonstrate the usefulness of the models to investigate clinical questions, namely optimization of ligament properties to participant-specific kinematics, and Monte Carlo (MC) analysis of the impacts of ligament injury on joint contact pressure, as an analogue for joint injury that may lead to osteoarthritis. Participant-specific models can be created in 2 hours and individual simulations performed in 45 seconds. This work lays the groundwork for future patient-specific modeling of the hand and wrist. |
