Abstract
The bone screw with internal extendable is a bone screw with an internal, extendable tang. The tang—part of a tang system—is concealed within the body of the screw until after placement. After the screw is threaded into the bone, the internal tang system is pushed out of the bone screw body, forcing one or more tangs to extend out of the body and into the bone. A driver allows the user to control the different steps of insertion, including converting rotational motion of a knob into linear motion of a rod, the rod moving through the screw body to force the tang to exit the bone screw body. The one or more tangs preferably exit the bone screw body at a tang exit portal formed by one or more tang exit guide surfaces.
