Abstract:
1. A crosspin comprising: a distal portion for engaging bone forming a far wall of a bone tunnel; a proximal portion for engaging bone forming a near wall of the bone tunnel; and an intermediate portion; said distal portion comprising a smooth-walled cylindrically shaped portion having a point at a first end thereof and a first notch at a second end thereof formed therein for encouraging bone ingrowth and preventing crosspin migration, the first notch having a rectangular cross-section to define two circumferential substantially right angle edges extending completely around a circumference of the crosspin; said proximal portion comprising a smooth-walled cylindrical portion having a second notch formed therein, the second notch having a rectangular cross-section to define two circumferential substantially right angle edges extending completely around the circumference of the crosspin, the proximal portion extending from the second notch to and including a proximal end of the crosspin; and said intermediate portion extends from the first notch to the second notch, is of cylindrical configuration in cross-section, and is smooth-walled throughout the extent thereof, so as to provide a full cross-section for maximum load-bearing strength, said distal portion, and said proximal portion, and said intermediate portion are of equal outer diameters, and said crosspin is of an absorbable material and is configured to crosspin a graft ligament in a bone tunnel.
