Abstract
A method is provided for stabilizing a bone. A plate is positioned over a bone. The bone plate has a polyaxial screw hole with a spherically curved seat. A bone hole is formed beneath the screw hole. A screw having a head with a spherical outer surface, and a threaded shaft with an internal cannula and a plurality of fenestrations is provided. The screw is driven through the first screw hole and into the bone hole until the outer surface of the head is supported by the spherically curved screw seat. A syringe provided with a needle is inserted into the internal cannula of the shaft of the screw. The syringe includes a bone injectable material that is injected through the needle, into the internal cannula, and out of at least one fenestration into the bone. After injection, the needle is removed from the screw shaft.
