Abstract:
1. A surgical blade for use with a saw for performing a one pass wedge osteotomy, comprising: a. a blade body having proximal and distal ends, wherein the distal end has a horizontal width narrower than a horizontal width of the proximal end; b. a cutting edge on the distal end of the blade body for making initial contact with a bone, the cutting edge having a first plurality of distally extending cutting teeth, positioned along a radius; c. a shaft having a slope descending from the proximal end to the cutting edge; d. a plurality of offset planes positioned along the slope, each offset plane having an upper surface; e. a plurality of rows of teeth positioned along an axis of the slope and positioned between the offset planes, each row of teeth having a horizontal width wherein a most proximal row of teeth has a widest horizontal width and the cutting edge has a narrowest horizontal width, and wherein along the slope a more proximal row of teeth is wider than a more distal row of teeth; f. each row of teeth comprising multiple teeth with distally extending cutting tips, said teeth positioned along a radius, and wherein said rows of teeth enable multiple cuts in bone with one linear pass of the surgical blade for defining and resecting a predetermined, predictable wedge shape of bone and for avoiding planar inconsistencies or inaccuracies associated with resecting a wedge of bone with more than one pass of a blade; g. a saw attachment base on the proximal end of the blade body for enabling attachment to an oscillating saw; and h. wherein the shaft does not have teeth on four surfaces and accommodates the slope on a fifth surface, and the cutting edge on a sixth surface.
