Abstract

An improved guide system and method permits a user to insert a fixation device, such as a pin, screw, wire and/or the like, into a bone portion. A guide system may comprise a handle portion and a body portion, wherein the body portion comprises one or more channels configured to facilitate placement and insertion of a fixation device.

Claims

1. A guide system comprising:

a handle portion and a body portion, the body portion having a channel extending the full length of the body portion, the channel sized to accept a fixation device;

a sleeve configured for insertion in the channel of the body portion, wherein the sleeve provides support to a fixation device in the space between the guide system and an insertion point.

2. A guide system of claim 1, wherein guide system further comprises a locking means.

3. A guide system of claim 2, wherein said sleeve comprises a gripping means.

4. A guide system of claim 3, the locking means comprising a knob, at least one flange located within said channel, wherein said flange is configured to slide into said gripping means of said sleeve upon activation of the locking means.

5. A guide system of claim 1, wherein the sleeve has an enlarged proximal head.

6. A guide system of claim 4, wherein the distal end of the sleeve comprises a plurality of jagged edges.

7. A guide system of claim 1, wherein the body portion comprises a beveled distal end.

8. A guide system of claim 7, wherein the beveled end is angled at about 35-45°

relative to the horizontal plane.

9. A guide system of claim 1, wherein the body portion comprises a plurality of laterally spaced-apart, parallel channels.

10. A guide system of claim 1, wherein the guide system is one of self-tapping and self-drilling.

11. A guide system of claim 1, wherein the fixation device is selected from a group consisting of a pin, bone screw, screw system, nail, lag screw, lag wire, guide wire, lag wire system, lagpin, wire, guide rod and drilling device.

12. A guide system of claim 1, further comprising a depth gauge, the depth gauge having a hollow tube and a set of measurement gradations, wherein the depth gauge is configured to determine a suitable length of a fixation device without removing the sleeve of the guide system.

13. A guide system of claim 1, wherein the fixation device is a lagwire system which comprises:

a head component configured to attach to the bone portion;

a wire having a first end and a second end, wherein the first end of the wire is configured to mate with the head component; and

a cap configured to mate with the second end of a wire.

14. A guide system of claim 1, wherein the guide system is operable to facilitate secure placement of a bone plate.

15. A guide system of claim 14, wherein the bone plate comprises a frame having a track, the track comprising an insertion niche configured to receive on to the track at least one of a fastening plate having an opening and a tension member.

16. A guide system of claim 15, wherein said guide system is operable to facilitate insertion of the fixation device in the opening of the fastening plate.

17. A depth gauge comprising:

a channel portion;

a set of measurement gradations; and

a head portion, wherein a guide wire may be inserted into the said head portion along said channel portion to measure of the length of a guide wire without removing the a sleeve of a guide system.

18. A depth gauge of claim 17, the tube comprising one of stainless steel, plastic, and titanium.

19. A method for using a guide system to insert a fixation device into a bone portion, the method comprising:

inserting a sleeve containing a fixation device into a channel of a guide system, wherein the guide system includes the channel sized to accept the fixation device;

aligning the channel at the desired insertion point;

abutting the angled end of the guide system to one of skin and bone; and

tapping the proximal end of the sleeve to insert the fixation device.
