Joint Prostheses

Elbow Hip Finger Knee Ankle

Hip joint prostheses

Hip joint prostheses are mainly comprised of a shell cup, shell liner, femoral head and stem.
Hip joints are reconstructed by sliding the articular surfaces of the femoral head and shell liner.

There are two ways of anchoring joint prosthesis, with bone cement or without bone cement.
Teijin Nakashima Medical’s products that are attached without bone cement are processed with a titanium mesh on the bone contact surface of the stem and shell cup.
With this process, to the components adhere by the natural growth of bone tissue into the porous surface, making for a longer lasting prosthesis.
