Abstract
A fixation device for use in securing a cranial bone flap with a cranial bone mass at the location of a burr hole. In one implementation the fixation device includes a closure plate having a substrate with an outer surface and an inner surface and with at least a portion of the inner surface adapted to be applied against the outer face of the outer edges of the cranial bone mass and the cranial bone flap at the location of the burr hole. The closure plate is also adapted with a burr hole fitting coupled to and spaced a distance below the inner surface of the substrate and adapted for being inserted entirely into the burr hole. The fitting may include one or more peripheral portions adapted for being pressed against the inner wall of the burr hole when the fitting is inserted therein. The peripheral portions are endowed with a freedom of movement that enables the fitting to be inserted into the burr hole.
