Abstract
A variable angle locking system having a humeral component with an underside at least partially defined by a cavity. A humeral stem is couplable to the humeral component and the system has a first washer defining a first through-hole and including a threaded portion. The system has an adaptor defining a second through-hole and having a shelf portion and an elongated second washer, the shelf portion being adapted to be received by the cavity of the humeral component. A spring washer is positioned between the first washer and the elongated second washer and defining a third through-hole. A screw is configured to lock the humeral component to the humeral stem at more than one angle relative to a common axis defined by the first, second and third through-holes. The screw includes a head portion having helical threads and an elongated shaft portion extending from the head portion.
