More Everyday Security and Comfort

For your customer, a rotation adapter improves security while driving, enabling him/her to swing the prosthesis out of the way. This minimizes the risk of the prosthetic foot impeding braking or accelerating and doesn’t limit the sound limb.

In addition, a rotation adapter eases daily activities like putting on shoes or changing socks because it brings the prosthetic foot within reach. The adapter also facilitates sitting with your legs crossed in a variety of positions.

The rotation adapter is easy to use: a press of a button starts the process, and the adapter locks again automatically. The low rotation resistance makes it more user-friendly.

Threaded Connector Saves Space

You can get the function of the rotation adapter in two versions: the 4R57 has a proximal pyramid adapter, and the 4R57=ST is threaded to reduce clearance. To attach, use the lamination anchor 4R111=N and the lamination anchor 4R43. The 4R57=ST should be used with the laminating aid 4X46=ST, which can be ordered separately.
