Abstract
A suture anchor comprises a distal anchor body which can be placed into bone and has a suture leading therefrom to adjacent soft tissue and a proximal anchor body. After placement of the distal anchor body the suture is tensioned and the proximal anchor body is then driven into the bone behind the distal anchor body to lock the suture in a knotless technique.
Claims16
A suture anchor system comprising:
- a distal anchor body having a suture attachment and a guide wire trailing proximally from the distal anchor body;
- and
- a proximal anchor body having a central bore passing therethrough sized to accommodate the guide wire, and one or more purchase enhancements extending from the proximal anchor body.
A suture anchor system comprising:
- a distal anchor body having a suture attachment and a distal awl tip, the distal anchor body being mounted on an awl driver whereby it can be driven into a bone to create a bone hole;
- and
- a proximal anchor body sized to fit into a bone hole created by the distal anchor body and having one or more purchase enhancements extending from the proximal anchor body.
A method for attaching a soft tissue to a bone, the method comprising the steps of:
- implanting into the bone a distal suture anchor body, leaving a guide wire extending proximally out of the bone from the distal suture anchor body;
- threading a suture from the soft tissue through a suture attachment on the distal suture anchor body, the suture extending from the soft tissue to the distal suture anchor body and out of the bone when the distal suture anchor body is implanted into the bone;
- and
- implanting over the guide wire and into the bone a proximal suture anchor body such that at least a portion of the suture is trapped between the proximal suture anchor body and the bone.
A method for attaching a soft tissue to a bone, the method comprising the steps of:
- piercing a bone and creating a bone hole with a distal suture anchor body which has a distal awl tip and a suture attachment with a length of suture passing therethrough, the distal suture anchor body being mounted on an awl driver;
- removing the awl driver and leaving the distal anchor body implanted into the bone hole with a first portion of the suture extending out of the bone hole;
- threading a second portion of the suture through the soft tissue;
- tensioning the suture by drawing on the first portion;
- and
- implanting into the bone hole proximal of the distal anchor body a proximal suture anchor body such that at least a portion of the suture is trapped between the proximal suture anchor body and the bone.
