A resorbable screw fastener comprising: a body portion defining a longitudinal axis and having a proximal end and a distal end, the body portion having a helical thread formed thereon, the helical thread having a first radial distance and the body portion having a second radial distance and a head portion disposed at the proximal end of the body portion, the head portion having a driver receiving structure defining a slot formed in an outer radial side surface of the head portion for transmitting rotational motion to the body portion, the head portion having an outer diameter substantially equal to the first radial distance of the helical thread, the head portion including a substantially flattened surface defined in an outermost diameter thereof, wherein the substantially flattened surface of the head portion is in radial registration with a substantially flattened surface formed in an outermost diameter of the helical thread, wherein the substantially flattened surfaces of the head portion and the helical thread are disposed between the second radial distance of the body portion and the first radial distance of the helical thread without projecting into the body portion, and wherein absorption of the resorbable screw fastener is nearly complete at approximately 12 months post implantation.
