Patients with osteoporosis have larger stress shielding at greater trochanter and calcar and larger stress concentration at stem tip zone .

骨质疏松者，股骨大转子与股骨矩区域的应力遮挡较大，而在杆端区域的应力集中明显。

Collared device for reducing stress shielding of calcar should be recommended for osteoporosis patients.

因此，骨质正常者应该选用非骨水泥假体，以减少大转子与股骨矩区域的应力遮挡；而骨质疏松者最好选用有肩托的假体，以减少股骨矩处的应力遮挡作用。

Non-cemented prosthesis should be better for normal bone quality patients because they could reduce stress shielding at greater trochanter and calcar.

骨质疏松者，股骨大转子与股骨矩区域的应力遮挡较大，而在杆端区域的应力集中明显。

1.It exists more higher stress in the cohere of handle and neck after various kinds prosthesis implantation,show this place is a key position;In the same time it shape a more higher stress dodge in the calcar femorale.

1各种假体植入后均在柄颈结合处有较高应力，提示该处是设计时的一个关键部位；同时股骨距处形成较高的应力遮挡。
