Radial saw blade and hub for osteotomy

An assembly, comprising:

• a hub member including a hub portion and a curved coupling portion, the curved coupling portion being radially offset from the hub portion with respect to a longitudinal axis of the hub portion about which the hub member is configured to rotate, the curved coupling portion including a slot defined in a distal surface of the curved coupling portion, the hub member further including at least one opening defined in a proximal surface of the hub member, the at least one opening being in fluid communication with the slot of the curved coupling portion;
• and
• a saw blade received in the slot of the curved coupling portion, the saw blade comprising:
• a main body including a first surface, a second surface on an opposite side of the main body from the first surface, a proximal edge portion, a distal edge portion comprising a plurality of cutting teeth, and first and second side portions extending between the proximal and distal edge portions, the saw blade having a thickness of from 0.005 inch to 0.018 inch;
• wherein the proximal edge portion comprises a U-shaped recess extending distally from the proximal edge portion, the proximal edge portion being coupled to the hub member such that the saw blade is held in a curved shape with the first surface defining an outer radius;
• wherein the saw blade includes at least one opening on a proximal end portion of the saw blade, and the hub member is injection molded or additively manufactured around the saw blade such that material of the hub member extends through the at least one opening in the saw blade to mechanically interlock the saw blade to the hub member.
