Transtibial System Components

willowwood-one-components-charts-2The WillowWood One® System incorporates advances in prosthetic technology and seal design to improve fit, function, and comfort of transtibial prosthetic sockets. The system prevents the prosthesis from loosening or detaching from the residual limb as well as preventing the limb from rotating within the socket.

This superior suspension results from each element of the system working together.

For coding recommendations, sizing charts, and patient criteria, please review system specifications.
