Stress is applied to the top of the femur
... and is transmitted through the
trabeculae of the cancellous bone
The stress is then transmitted
through the cortical bone
Healthy bone
Stress is applied to the top of the femur
... and the higher modulus of the
implant material means stresses
are transmitted down the stem of
the implant
As a result, less stress is carried by the
bone in this region, so resorption is
likely to occur
