Patent ID: 8821557

Claim:
A resorbable screw fastener, comprising: a body portion defining a longitudinal axis and having a proximal end and a distal end, the distal end having a distal surface extending non-perpendicularly relative to the longitudinal axis, the body portion having a helical thread formed thereon, the helical thread defining a substantially flattened surface formed in an outermost diameter of the helical thread; and an unthreaded head portion disposed at the proximal end of the body portion and defining a longitudinal axis, the head portion having a proximal end and a distal end, the distal end of the head portion having a distal surface extending non-perpendicularly relative to the longitudinal axis, the unthreaded head portion including a substantially flattened surface formed in an outermost diameter thereof, wherein the substantially flattened surface of the unthreaded head portion is in radial registration with the substantially flattened surface formed in an outermost diameter of the helical thread, wherein the substantially flattened surface formed in the outermost diameter of the helical thread projects partially radially inward from the outermost diameter of the helical thread.
