A surgical saw blade, comprising: an elongated blade bar, the blade bar having opposed proximal and distal sections, the proximal section having a feature for releasably holding the blade bar to a powered surgical sagittal saw, the distal section being formed with a void space and a primary opening into the void space; a blade head, the blade head having: a base disposed in the blade bar distal section opening that is pivotally mounted in the blade bar distal section opening; and a crown integral with the base that extends through and outside of the blade bar distal section primary opening, the crown being formed with teeth; and at least one drive rod that has a distal end moveably attached to the blade head base and a proximal end adjacent blade bar proximal section, the proximal end adapted to be attached to a drive member integral with the surgical sagittal saw; characterized in that, the blade bar is formed with at least one secondary opening, in the distal section separate from the primary opening, the secondary opening opening into the void space so that debris can flow from out of the void space through the secondary opening.
