Geometric hip measurements. A = femoral neck width; B = femoral head diameter; C = femoral neck axis length; D = medial cortical width (inferior trochanter); E = lateral cortical width (inferior trochanter); F = distance between femoral head's rotation center and pelvic center; G = neck shaft angle; H = hip axis length; I = femoral offset; J = thickness of femoral shaft at inferior trochanter; K = medullary width 20 mm above lesser trochanter.
