Surgical cage for spinal support has spacer disc with rotatable foot at set spacing

摘要

The surgical spinal support cage has a spacer disc (1) with opposed faces 92,3) and a sidewall (13). A foot (13) is mounted for rotation on the spacer around an axis (6) which is parallel to the plane of the faces. The gap between at least one end (7,8) of the foot and the axis of rotation is greater than that between at least one of the faces of the base and the axis of rotation.
