The supplied materials are part of a research project which aims is to develop a patient-specific hard- and soft-tissue model for simulating forearm motion with respect to functional disability and instability. Besides improving the preoperative diagnosis of soft tissue associated injuries, such as for distal radius instability, the ultimate goal is to predict the surgical outcome preoperatively by analyzing the forearm motion before and after simulated surgery. This would enable the surgeon to select the optimal treatment specific to the pathology and biomechanics of the patient.
