ABSTRACT:
An orthopedic interference screw has a hard, self-threading front section and a bioabsorbable rear section. The two sections are conjoined and threaded such that the hard front section cuts threads into the bone and the softer rear section follows the threads into the bone. Preferably, the screw has an axial bore for matingly receiving a turning tool such as a hex wrench.
