Abstract
A lock indicator gauge is provided to provide an indication as to whether a bone screw construct is in a locked or an unlocked condition when the lock indicator gauge is operatively engaged with the bone screw construct. A plunger longitudinally disposed within a housing of the lock indicator gauge translates within the housing by a distance that corresponds to the relative positions of inner and outer housings of the bone screw construct, wherein the relative positions of the inner and outer housings is dependent on whether the bone screw construct is in a locked or an unlocked condition.
