LAGWIRE SYSTEM AND METHOD FOR THE FIXATION OF BONE FRACTURES
A lagwire system and method for facilitating the fixation of bone fractures is disclosed. The lagwire system includes an anchor component, a wire, a sleeve and a cap. The sleeve and cap are operable to slide along the length of the wire and also operable to be used to fixate a fracture individually by using a canal prepared by the anchor and wire.
1 . A method for treating a bone fracture comprising:
inserting a lagwire system into said bone, wherein said lagwire system comprises an anchor and wire;
navigating said lagwire system to a desired position within said bone causing said lagwire system to ream a canal through a center portion of said bone and across said bone fracture;
removing said lagwire device; and
inserting a polymer wire into said canal such that said polymer wire bridges said bone fracture.
2 . The method according to claim 1 , wherein said polymer wire is a peek material.
3 . The method according to claim 1 , wherein said polymer wire is threaded.
4 . The method according to claim 1 , further comprising applying tension on said lagwire system to decrease a gap at said bone fracture;
5 . The method according to claim 1 , further comprising threading a cap into said canal after said polymer wire is inserted.
6 . The method according to claim 5 , further comprising retaining said polymer wire in position relative to said bone with said cap.
7 . The method according to claim 6 , wherein said cap is configured to thread onto a proximal portion of said polymer wire.
8 . The method according to claim 1 , wherein said polymer wire is cannulated such that said polymer wire is a sleeve that is configured to slide over another wire.
9 . The method according to claim 8 , wherein a treatment is delivered through a center of said polymer wire.
10 . The method according to claim 9 , wherein said treatment comprises at least one of a medication, an adhesive, an ultrasonic vibration, and a bonding material.
11 . An implant device configured to be inserted into a canal prepared by a flexible reaming device, said implant device comprising a flexible sleeve comprised of a PEEK material having sufficient rigidity to be inserted into said canal.
12 . The device of claim 11 , wherein said sleeve is configured to receive a wire and is configured to slide longitudinally along a length of said wire.
13 . The device of claim 12 , wherein said sleeve comprises external threads along at least a portion of an exterior surface.
14 . The device of claim 11 , wherein said sleeve is configured to provide fixation of said first bone portion relative to said second bone portion at a specified length along said sleeve.
15 . The device of claim 11 , wherein said flexible wire includes a medicated coating.
16 . The device of claim 15 , wherein said medicated coating is an antibiotic.
17 . The device of claim 13 , further comprising a cap having internal threads which mate with said external threads of said sleeve, wherein said cap further comprises a threaded external distal portion which mates with said first bone portion as a screw interface, and wherein said cap is configured to receive said sleeve such that said cap is configured to slide distally along a length of said sleeve, wherein said cap is configured to engage said sleeve such that said sleeve is at least partially restricted from moving distally relative to said cap.
18 . The implant device of claim 11 , further comprising an anchor and flexible wire, wherein said anchor has a tip.
19 . The implant device of claim 11 , wherein said sleeve comprises a proximal end configured to receive a driver.
20 . The implant device of claim 17 , wherein said sleeve and said cap are configured to provide reduction between said first bone portion and said second bone portion.
