An Ethnographic Analysis of Teaching Responses to Error in Surgical Simulation
Background: To embed surgical simulation into residency training, faculty surgeons are often recruited as instructors due to their expertise on the subject matter, rather than their training as educators. Faculty surgeons experience with teaching procedural skills comes from one-on-one teaching in …

Spatially-localized correlation of MRI and mechanical stiffness to assess cartilage integrity in the human tibial plateau
… and collagen. In current orthopaedic surgical practice, the gold standard for evaluating articular cartilage integrity is the use of a hand probe during arthroscopy. Mechanical probing, however, is invasive and requires anesthesia. Tightly confined areas of the articular surface can be …

Development and evaluation summaries of a percutaneous nephrolithotomy (PCNL) surgical simulator
Traditional surgical training methods, such as the use of cadavers, and porcine models (pigs) fall short of providing the realistic, real-time feedback necessary for mastering complex procedures. Virtual reality (VR) simulators with haptics offer a significant improvement, delivering immersive and …
