Abstract
A method of connecting a suture to a bone including the steps of inserting at least one suture anchor into the bone, and disposing a suture loop about a crossbar of the suture anchor in such a way that when a proximally directed force is applied to the suture loop, a free end of the crossbar engages a transverse edge of the body of the suture anchor to limit proximal motion of the crossbar and capture the suture loop.
Claims6
A method of connecting a suture to a bone, comprising:
- inserting at least one suture anchor into the bone, the suture anchor comprising:
- a body having a proximal end, a distal end, an axial recess extending from the proximal end toward the distal end, and a transverse edge;
- and
- a crossbar extending from the body and across the axial recess such that the crossbar has a free end and a fixed end and the free end of the crossbar is normally disposed distally of the transverse edge of the body,
- wherein the crossbar is flexible such that when a distally directed force is applied to the crossbar, the free end of the crossbar is deflected relative to the fixed end and positioned in the axial recess and when a proximally directed force is applied to the crossbar, the free end of the crossbar engages the transverse edge to limit proximal motion of the crossbar;
- and
- disposing a suture loop about the crossbar by distally deflecting the free end of the crossbar relative to the fixed end and moving the suture loop past the free end of the crossbar in such a way that when a proximally directed force is applied to the suture loop, the free end of the crossbar engages the transverse edge of the body to limit proximal motion of the crossbar and capture the suture loop.

A method of connecting a suture to a bone, comprising:
- inserting at least two suture anchors into the bone, each of the suture anchors comprising:
- a body having a proximal end, a distal end, an axial recess extending from the proximal end toward the distal end, and a transverse edge;
- and
- a crossbar extending from the body and across the axial recess such that the crossbar has a free end and a fixed end and the free end of the crossbar is normally disposed distally of the transverse edge of the body,
- wherein the crossbar is flexible such that when a distally directed force is applied to the crossbar, the free end of the crossbar is deflected relative to the fixed end and positioned in the axial recess and when a proximally directed force is applied to the crossbar, the free end of the crossbar engages the transverse edge to limit proximal motion of the crossbar;
- disposing a first suture loop of the suture about the crossbar of one of the suture anchors by distally deflecting the free end of the crossbar relative to the fixed end and moving the first suture loop past the free end of the crossbar in such a way that when a proximally directed force is applied to the first suture loop, the free end of the crossbar engages the transverse edge of the body to limit proximal motion of the crossbar and capture the first suture loop;
- and
- disposing a second suture loop of the suture about the crossbar of the other suture anchor by distally deflecting the free end of the crossbar relative to the fixed end and moving the second suture loop past the free end of the crossbar in such a way that when a proximally directed force is applied to the second suture loop, the free end of the crossbar engages the transverse edge of the body to limit proximal motion of the crossbar and capture the second suture loop.
