Abstract

The disclosure relates to medical devices and methods of manufacturing medical devices. An orthopedic screw includes an inner core member having a head having a first outer diameter, a tip having a second outer diameter, and a body extending between the head and the tip and having a third outer diameter that is less than the first outer diameter and the second outer diameter. An outer body member is disposed circumferentially around the body of the inner core member and defines an outer body member external thread. The tip of the inner core member can define an inner core member external thread that forms an interrupted thread with the outer body member external thread.
