Abstract
Novel bone screw and plate assemblies including locking confirmation mechanisms are provided. In certain cases, a locking confirmation mechanism is operably attached to the plate, and comprises a toggling arm having an upper portion, a mid-portion and a lower portion. When a bone screw is positioned in a plate in an unlocked configuration, the locking confirmation mechanism assumes a first position. When the bone screw is positioned in the plate in a locked configuration, this causes the locking confirmation mechanism to pivot and assume a second position. The locking confirmation mechanism thus provides a convenient visual and/or tactile means to assess when the screw is in a locked configuration.
