Stress Distribution Visualization on Pre- and Post-Operative Virtual Hip Joint

In this paper, we present a case study using a spreadsheet-like interface for exploring biomedical datasets generated by a biomechanical model of the hip. The case we analyze here is an osteotomy corrective surgery that reorients the femoral body in relation to the femoral neck, somewhat like the intertrochanteric osteotomy described by Imhäuser (2). That is a procedure recommended by most authors as a surgical treatment of severe slipped capital femoral epiphysis. Then we compare estimated contact area of the pre- and post-operative hips from a threshold of the computed stress.
