Abstract

A joint arthrodesis system adapted for use in joint surgeries. Among other things, the joint implant has an anterior cutting edge and a rotatable cutter supported by a rotatable shaft.

Claims (40)

1. A joint arthrodesis system comprising:

a) a framework comprising:

i) a central axis measured in a longest dimension of said framework; said framework including a length greater than a width;

ii) openings outward from said central axis;

iii) an anterior side comprising a cutting edge integral with said anterior side;

iv) a surgeon facing side at an end opposite said anterior side; said anterior side having a lesser cross-sectional area than a cross-sectional area of said surgeon facing side, wherein said cross-sectional areas are determined perpendicular to said central axis;

v) a plate seated within said cross-sectional area of said surgeon facing side and affixed to said framework, wherein said plate is perpendicular to said longitudinal axis and comprises one or more apertures capable of reciprocating with one or more instruments;

vi) a shaft, coaxial with said central axis, extending between an inner side of said plate and said cutting edge; and

vii) arms connected with said shaft; said arms supporting cutters comprising one or more blades, wherein on rotation of said shaft, said one or more blades rotate about said central axis in a clockwise or counterclockwise direction; and

b) a tool capable of rotating said shaft.

2. The joint arthrodesis system of claim 1 , wherein said framework comprises four lateral sides.

3. The joint arthrodesis system of claim 2 , wherein one or more surfaces of said framework comprises barbs and/or micropores.

4. The joint arthrodesis system of claim 3 , wherein said framework comprises recesses adapted to receive said cutters, said recesses positioned diagonally from each other relative to two opposed lateral sides said framework.

5. The joint arthrodesis system of claim 4 , wherein outermost ends of said one or more blades extend to outward edges of said recesses.

6. A joint implant comprising a framework; said framework comprising:

a) a central axis measured in a longest dimension of said framework, wherein said framework's length is greater than said framework's width;

b) openings outward from said central axis;

c) an anterior side comprising a cutting edge;

d) a surgeon facing side at an end opposite said anterior side, wherein said surgeon facing side is perpendicular to said central axis and comprises one or more apertures capable of reciprocating with one or more instruments;

e) a shaft, coaxial with said central axis, extending between an inner side of said surgeon facing side and said cutting edge; and

f) one or more arms connected with said shaft; said one or more arms supporting one or more cutters comprising one or more blades, wherein on rotation of said shaft, said one or more blades rotate about said central axis in a clockwise or counterclockwise direction.

7. The joint implant of claim 6 , said framework comprising four lateral sides.

8. The joint implant of claim 7 , said shaft comprising a receptacle for interacting with a tool capable of rotating said shaft.

9. The joint implant of claim 8 , wherein said one or more arms comprise one or more sharp edges adapted to morselize bone.

10. The joint implant of claim 8 , wherein one or more surfaces of said framework comprises barbs and/or micropores.

11. The joint implant of claim 8 , said framework comprising recesses adapted to receive said cutters, said recesses positioned diagonally from each other relative to two opposed lateral sides said framework.

12. The joint implant of claim 11 , wherein said anterior side has a lesser cross-sectional area than a cross-sectional area of said surgeon facing side; said cross-sectional areas determined perpendicular to said central axis.

13. A joint implant comprising a framework; said framework comprising:

a) a central axis measured in a direction of a longest dimension of said framework;

b) openings outward from said central axis;

c) an anterior side comprising a cutting edge; d) a surgeon facing side at an end opposite said anterior side; said surgeon facing side comprising one or more apertures;

e) a rotatable shaft, coaxial with said central axis, extending between said cutting edge and said surgeon facing side; and

f) a first arm connected with said shaft; said first arm supporting a first cutter comprising one or more blades, wherein on rotation of said shaft, said blades rotate about said central axis in a clockwise or counterclockwise direction.

14. The joint implant of claim 13 , said framework comprising four lateral sides and a length greater than a width.

15. The joint implant of claim 14 , said shaft comprising a receptacle for interacting with a tool capable of rotating said shaft.

16. The joint implant of claim 14 , wherein one or more surfaces of said framework comprises barbs and/or micropores.

17. The joint implant of claim 15 , wherein said first arm comprises one or more sharp edges adapted to morselize bone.

18. The joint implant of claim 15 , said framework further comprising a second arm connected with said shaft; said second arm supporting a second cutter comprising one or more blades, wherein on rotation of said shaft, said blades rotate in a clockwise or counterclockwise direction.

19. The joint implant of claim 18 , said framework's anterior side having a lesser cross-sectional area than a cross-sectional area of said surgeon facing side.

20. The joint implant of claim 19 , said framework comprising recesses adapted to receive said first and second cutters.
