Hip contact stress sensor placement within a cadaver hip joint. (a) An oblique view of the femur showing the sensor positioned on the femoral head. The outer perimeter of the sensor active region rests approximately at the equator of the head. (b) An anterior view, showing the femoral head within the acetabulum. The periphery of the active region is still visible at the edge of the labrum. (c) A mediolateral view of the acetabulum only; arrows indicate where the sensor has been sutured to the labrum.
