From: Compression or tension? The stress distribution in the proximal femur
One-legged stance. The distribution of principal stresses in a model of one-legged stance with spring elements at a prestrain of 5%, a vertical force of body weight applied to the femur and an abductor force of three times body weight. The lengths and directions of the arrows show the relative magnitudes and directions of compression, in blue, and tension, in red.
