Abstract
An orthopedic interference screw for compression anchoring a bone graft in a bore formed in a bone mass. The interference screw includes a biocompatible body with a root. A screw thread is formed over substantially all of the root. The screw thread includes buttress structure on only one side of the screw thread so that forces applied to the screw thread from a side remote from the buttress structure will be buttressed by the buttress structure.
