Summary

The purpose of this study is to determine if there is a difference in stress shielding and bone resorption of the proximal femur in two anatomical stem total hip designs.

Detailed description

Stress shielding related bone resorption in the proximal femur after total hip arthroplasty continues to be a problem. The purpose of this prospective, randomized study was to evaluate which of the two anatomical stem designs achieved a more physiological load transfer by assessing bone mineral changes in the proximal femur after stem implantation.

Conditions

• Osteoarthritis of Hip

Interventions

Type	Name	Description
DEVICE	Stemless femoral component	Total hip femoral component anatomically designed for a proximal fit without a stem
DEVICE	IPS, Depuy cementless femoral stem	Anatomical proximal fitted cementless stemmed femoral component
