Hip Arthroplasty

A prosthetic hip joint should imitate normal hip joint activities as closely as possible. This means that the artificial hip should allow us to

§         stand without muscle effort

§         walk with least energy expenditure

§         sit normally

To be able to do them, we need a hip that can :

• Extend slightly
• Flex upto 30 ⁰
• Abduct on weight bearing
• Rotate in full extension
