Suture distal locking
A system for locking an intramedullary nail to a bone includes a first plate sized and shaped to be inserted through a channel of an intramedullary nail and dimensioned to prevent its passing through a locking hole of the intramedullary nail and a second plate sized and shaped to be positioned along a portion of an exterior of a hole drilled in the bone and dimensioned to prevent its passing through the hole drilled in the bone along with a connector couplable to the first and second plates and slidable through the channel of the intramedullary nail to extend through the locking hole from an interior of the channel to an exterior of a bone in which the intramedullary nail has been inserted.
1. A method for fixing an intramedullary nail within a bone, comprising:
inserting an intramedullary nail through a medullary canal of a bone, the intramedullary nail including a channel extending longitudinally therethrough and a locking hole extending laterally therethrough from an interior of the channel to an exterior thereof;
passing a connector through an eyelet at a proximal end of a flexible drill and through first and second openings of a first plate to form a closed loop, wherein the connector is thread-like;
inserting the drill distally through the channel of the intramedullary nail and laterally out of the locking hole to drill a corresponding hole in the bone;
drawing the drill through the locking hole and the corresponding hole until the first plate is positioned along a portion of an interior of the channel surrounding the locking hole;
cutting the connector to form first and second ends thereof and removing the drill;
inserting the first end into a first opening of a second plate and the second end into a second opening of the second plate; and
tying the first and second ends such that a tension is applied to the connector and the second plate is positioned against a portion of an exterior of the bone surrounding the corresponding hole so that the first and second plates are attached to one another via the connector, fixing the intramedullary nail to the bone.
2. The method of claim 1 , further comprising inserting a drill guide distally through the channel and positioning the drill guide such that a slot thereof is aligned with the locking hole of the intramedullary nail, the drill guide including a lumen extending longitudinally therethrough and the slot extending laterally therethrough in communication with the lumen.
3. The method of claim 2 , wherein the drill is inserted into the channel via the lumen of the drill guide, the drill guide including a ramped surface opposing the slot such that when the drill is inserted distally therethrough a distal end of the drill comes into contact with the ramped surface and is guided through the slot of the drill guide and the locking hole of the intramedullary nail.
4. The method of claim 2 , further comprising removing the drill guide upon drawing of the drill through the corresponding hole of the bone.
