Smooth, loose-fitting stem
Design rationale
Design rationale
Toggle of the stem within the radius is designed to allow the radial head to articulate congruently with the capitellum³
Movement of the implant is designed to be guided by the annular ligament rather than by the position of the radial neck³
Loose fit designed to allow the forearm to rotate around the stem rather than at the articular surface of the capitellum
