An apparatus () for attachment to bone () comprises a plate () having a lower surface () for abutting against the bone () and an upper surface () opposite the lower surface (). The plate () further includes a plurality of through-holes () extending between the lower and upper surfaces (and). Each through-hole () has an associated countersink (). Each through-hole () defines a substantially square opening in the lower surface () of the plate () and each associated countersink () defines a circular opening in the upper surface () of the plate ().

Implantable device for covering and opening in a cranium

An implantable apparatus () for attaching bone fragments in a bone fracture reduction procedure comprises a bone affixation plate () and a polymeric applicator () having a deflectable portion () that is deflectable to engage a portion () of the plate to attach the applicator to the plate. The applicator () is thereafter deflectable to disengage from the portion () of the plate () to remove the applicator from the plate. The applicator (), when attached to the plate (), enables the plate to be handled and manipulated during the bone fracture reduction procedure. The applicator () may includes information () for identifying the plate ().

Implantable bone fracture reduction apparatus having a polymeric applicator

An apparatus ( ) for attaching to bone comprises a one-piece, homogeneous screw ( ) engageable by a driver for driving the screw into bone. The screw ( ) has a shaft portion ( ) and a head portion ( ) extending from the shaft portion. The shaft portion ( ) has an outer surface ( ) with a thread convolution ( ). The head portion ( ) includes oppositely disposed first and second axial ends ( and ) and a peripheral surface ( ) extending between the ends. The first axial end ( ) adjoins the shaft portion ( ). The second axial end ( ) includes an end surface ( ). The head portion ( ) has a plurality of slots ( ) extending axially from the end surface ( ) to the first axial end ( ). The slots ( ) further extend through the peripheral surface ( ) of the head portion ( ) and radially inward from the peripheral surface of the head portion. In accordance with another feature, the apparatus ( ) further comprises a screwdriver ( ) for driving the screw ( ) into bone ( ).
