Ligament screw attachment device

Abstract

A bone block assembly including a bone block having a proximal end, a distal end, a central axis defined therethrough, and a hole formed therethrough, and a threaded screw having a proximal end, a distal end, and a first eyelet formed on the proximal end of the threaded screw, the threaded screw configured to be received within the hole of the bone block. The first eyelet of the threaded screw is, at least partially, exposed on the proximal end of the bone block when the threaded screw is fully engaged with the bone block. The first eyelet of the threaded screw is configured to receive a suture.

What is claimed is: 
     
         1 - 10 . (canceled) 
     
     
         11 . A ligament screw comprising:
 a screw body having a proximal end, a tapered distal end and a longitudinal axis extending therebetween, a surface of the screw body comprising a plurality of turns of a screw thread;   a first eyelet formed on the proximal end of the screw body configured to receive a suture; and   a second eyelet formed on the distal end of the screw body configured to receive a suture;   wherein a tip of the screw thread is not pointed so as to capture a cortical layer at a bony-ligament junction of a graft.   
     
     
         12 . The ligament screw of  claim 11 , wherein the screw thread is a self-tapping screw thread configured to form corresponding threads within a hole in a bone block. 
     
     
         13 . The ligament screw of  claim 11 , wherein the screw body comprises a cannulation extending along the longitudinal axis for receiving a surgical tool. 
     
     
         14 . The ligament screw of  claim 13 , wherein the cannulation extends through an entire length of the screw body. 
     
     
         15 . The ligament screw of  claim 13 , wherein the cannulation extends through a partial length of the screw body. 
     
     
         16 . The ligament screw of  claim 11 , wherein the screw body is configured to engage with a driving tool. 
     
     
         17 . The ligament screw of  claim 11 , wherein the screw body is formed from a rigid, biocompatible material. 
     
     
         18 . The ligament screw of  claim 11 , wherein the screw body is formed from stainless steel. 
     
     
         19 . The ligament screw of  claim 11 , wherein the proximal end of the screw body is tapered.
