Abstract

A device for treating a bone includes (a) an elongate body sized and shaped for insertion into a bone and extending longitudinally from a proximal end to a distal end, the elongate body including a channel extending therethrough and a coating along an outer surface thereof, the coating adapted to absorb a selected frequency of light such that, when the selected frequency of light is applied thereto, portions of the coating melt to form a mass; and (b) a first anchor member slidably mountable over the elongate body and movable therealong from a first position at the proximal end of the elongate body to a second position adjacent a bone into which the elongate body has been inserted to cooperate with the mass to fix the elongate body to the bone.

Claims (30)

1. A method for treating a fractured bone, comprising:

inserting an elongate body of a bone fixation device through a bone such that a distal end of the elongate body extends distally past a far cortex of the bone, the elongate body extending longitudinally from a proximal end to the distal end, the elongate body including a channel extending therethrough and a coating adapted to absorb a selected frequency of light, the coating extending along an outer surface of the elongate body;

inserting a light fiber through the channel of the elongate body until a distal tip of the light fiber is radially within the distal end of the elongate body;

activating the light fiber such that the coating along the distal end of the elongate body melts to form a mass; and

moving a first anchor member along the elongate body from a first position at the proximal end of the elongate body to a second position adjacent a near cortex of the bone to fix the elongate body to the bone.

2. The method of claim 1 , further comprising reducing fractured portions of the bone and drilling a hole therethrough.

3. The method of claim 1 , further comprising severing a proximal portion of the elongate body from a first implanted portion of the elongate body, the first implanted portion extending from the distal end to the first anchor member, the bone fixation device including a second anchor member, wherein a length of the proximal portion of the elongate body is sufficient to form a second implanted portion of the elongate body.

4. The method of claim 3 , further comprising:

inserting the proximal portion of the elongate member into another portion of bone;

inserting the light fiber through the channel of the proximal portion until a distal tip of the light fiber is radially within a distal end of the proximal portion;

activating the light fiber such that the coating along the distal end of the proximal portion melts to form a mass; and

moving a second anchor member from the proximal end of the proximal portion to a position adjacent the another portion of bone to fix the proximal portion to the associated bone.

5. The method of claim 4 , wherein the bone fixation device includes a third anchor member, wherein a length of the proximal portion is sufficient to form a third implanted portion.

6. The method of claim 1 , further comprising tightening the first anchor member such that elongate body is moved proximally therethrough to compress fractured portions of the bone.

7. The method of claim 1 , further comprising positioning a bone plate along the bone such that the elongate body is inserted through an opening of the bone plate.

8. The method of claim 1 , further comprising welding the first anchor member to the elongate body in the second position by activating the laser device such that the coating along a portion of the elongate body radially within the first anchor member is melted.

9. The method of claim 1 , further comprising crushing the first anchor member to positionally fix a position of the first anchor member with respect to the elongate body.

10. A method for treating a fractured bone, comprising:

inserting an elongate body of a bone fixation device through a bone such that a distal end of the elongate body extends distally past a far cortex of the bone, the elongate body extending longitudinally from a proximal end of the elongate body to the distal end, the elongate body including a first material adapted to absorb a selected frequency of light and a second material adapted to transmit the selected frequency of light, the first material being disposed at the distal end of the elongate body;

applying a laser to the elongate body;

activating the laser such that the first material of the elongate body melts to form a mass, and such that the second material does not melt; and

moving a first anchor member along the elongate body from a first position at the proximal end of the elongate body to a second position adjacent a near cortex of the bone to fix the elongate body to the bone.

11. The method of claim 10 , further comprising applying the laser directly to the second material of the elongate body at the proximal end.

12. The method of claim 11 , wherein the first material comprises a colored pigment and the second material comprises a polymer.

13. The method of claim 10 , further comprising crushing the first anchor member to positionally fix a position of the first anchor member with respect to the elongate body.

14. The method of claim 10 , further comprising reducing fractured portions of the bone and drilling a hole therethrough.

15. The method of claim 10 , further comprising severing a proximal portion of the elongate body from a first implanted portion extending from the distal end to the first anchor member, the bone fixation device including a second anchor member, wherein a length of the proximal portion of the elongate body is sufficient to form a second implanted portion.

16. The method of claim 10 , further comprising tightening the first anchor member such that elongate body is moved proximally therethrough to compress fractured portions of the bone.

17. The method of claim 10 , further comprising positioning a bone plate along the bone such that the elongate body is inserted through an opening of the bone plate.

18. The method of claim 10 , further comprising crushing the first anchor member to positionally fix a position of the first anchor member with respect to the elongate body.
