An arbor press staple and washer of the invention is for use in a practice of a surgical procedure for securing a ligament, that is either natural or prosthetic, onto a bone cortex surface and includes a staple having spaced equal parallel legs with a flat web arranged between the top ends of the staple legs. The staple is for driving into a bone cortex surface and includes barb ridges around three of its four sides for resisting staple withdrawal. The staple flat web includes at least one hole, that is preferably tapped, formed therethrough that is for receiving a threaded section of a threaded pin turned therethrough, and includes a pair of guide posts that extend, at right angles, from the web undersurface. An arbor plate type washer, that is a flat plate that has concave notches formed in opposite ends, is for arrangement between the staple legs, the concave notches sliding along the staple legs prohibiting washer rotation. The flat plate includes a pair of guide post holes that receive the guide pins that extend from the staple web undersurface, and includes a center smooth hole wherethrough a pin end of the threaded pin travels to where the threaded section lower face and engages the flat plate top surface, the continued turning of the threaded pin to urge the washer away from the staple web, causing spikes that extend from the washer flat plate undersurface to travel through a ligament that the staple legs straddle and into a bone cortex surface.
An arbor press staple and washer comprising, a staple having a pair of spaced apart legs and including a web section extending between top ends of said staple legs that includes at least one hole formed therethrough;
A method for mounting a section of a ligament onto a bone cortex utilizing a combination of a staple with a washer disposed between legs of the staple that is moved against a ligament surface comprising the steps of, selecting a location on a bone cortex surface to attach a ligament section to and driving pointed ends of legs of a staple therein such that said staple legs straddle said ligament section positioned thereon and urge a washer disposed between said staple legs to slide against said ligament section;
An arbor press staple comprising, a staple having a pair of spaced apart legs and including a web section extending between top ends of said staple legs, and said web section includes at least one hole formed therethrough;
An arbor press staple and washer for securing soft tissue adjacent to bone comprising, a staple having a pair of spaced apart legs adapted for insertion into bone and including a web section extending between top ends of said staple legs;
