Graft collection and containment system for bone defects

1. A device for containing bone graft material, comprising:

an inner sleeve extending longitudinally from a proximal end to a distal end; and

an outer sleeve surrounding the inner sleeve and extending longitudinally from a proximal end to a distal end such that a bone graft collecting space is formed therebetween, the proximal end of the of the inner sleeve extending proximally past the proximal end of the outer sleeve and the distal end of the inner sleeve extending distally past the distal end of the outer sleeve, the proximal and distal ends of the inner sleeve being sized and shaped for insertion into a medullary canal of a bone within which the device is to be employed.

2. The device of claim 1 , wherein at least one of the inner and outer sleeves includes a plurality of openings extending therethrough sized to permit fluids to pass therethrough while preventing the passage of bone graft material therethrough.

3. The device of claim 1 , wherein one of the inner and outer sleeves includes a plurality of slits extending through a portion of a circumference thereof to permit the device to flex along a longitudinal axis thereof.

4. The device of claim 1 , wherein a contour of the inner sleeve is selected to substantially match a contour of a medullary canal of a bone within which the device is to be employed.

5. The device of claim 1 , wherein a contour of the outer sleeve is selected to substantially match a contour of an exterior surface of a bone within which the device is to be employed.

6. The device of claim 1 , wherein one of the proximal and distal ends of the inner sleeve includes a longitudinal slit extending therethrough to separate the one of the proximal and distal ends into opposed jaws biased toward a spaced configuration in which the jaws extend across a space larger than a medullary canal within which they are to be received, the jaws being flexibly movable toward one another to an insertion configuration in which the one of the proximal and distal ends is sized for insertion into a medullary canal so that, upon release within a medullary canal the jaws create a friction fit therewith.

7. The device of claim 1 , wherein a proximal tip of the proximal end is rounded to facilitate insertion into a medullary canal.

8. The device of claim 1 , wherein the outer sleeve includes a reinforced section extending longitudinally along a portion of a length thereof, the reinforced section having a wall thickness greater than that of a remaining portion of the outer sleeve.

9. The device of claim 8 , wherein the outer sleeve includes a slot extending through the reinforced section sized to receive a fixation element therethrough.

10. The device of claim 1 , wherein the inner and outer sleeves are integrally formed and connected to one another via a plurality of ribs extending longitudinally therebetween.

11. The device of claim 1 , wherein the inner and outer sleeves are removably connected to one another.

12. The device of claim 1 , wherein a lumen of the inner sleeve is sized and shaped to accommodate an intramedullary rod therein.
