CLAIMS

1. A bone plate (100) for fixing distal radius (405) fracture comprising:

a volar-shaped head (99) to be positioned at the distal radius (405);

a shaft (98) inclinedly extending from the head (99);

a plurality of K-wire openings (111) distributed over the head (99) for receiving K-wires (118) to temporarily secure the plate (100); and

a plurality of fastening means openings (101, 102, 103, 108) distributed over the head (99) and the shaft (98) for receiving fastening means (104, 105, 106, 107) to fix the plate (100) to the distal radius (405);

characterized by an insertion cavity (109) formed at the junction of the head (99) and the shaft (98) in such a manner as to provide an accessible space for efficient insertion of bone graft material.

2. A bone plate (100) according to claim 1, wherein the head (99) has a thickness of 1.5 mm to 2.5 mm and is tapered from the junction of the head (99) and the shaft (98), towards the distal end of the plate (100).

3. A bone plate (100) according to claim 1, wherein the shaft (98) has a thickness of 2.0 mm to 3.0 mm.

4. A bone plate (100) according to claim 1, wherein the shaft (98) has at least one waisted region (117) for uniform distribution of stresses.

5. A bone plate according to claim 1, wherein the angle of inclination between the head (99) and the shaft (98) lies within the range of 20° to 30°.

6. A bone plate (100) according to claim 1, wherein the fastening means (104, 105, 106, 107) are locking screws (104), cortical screws (105), locking smooth pegs (106), locking threaded pegs (107) or a combination of any two or more thereof.

7. A bone plate (100) according to claim 1, wherein the plurality of fastening means openings (103) at the distal end of the head (99) are aligned in an arc (400) to allow the fastening means (104, 106, 107) to engage subchondral regions of the distal radius (405).

8. A bone plate (100) according to claim 7, wherein others of the fastening means openings (102) are aligned on the head (99) in such a manner as to allow the fastening means (104, 106, 107) to engage volar and medial subchondral regions of the distal radius (405).

9. A bone plate (100) according to claim 8, wherein still further fastening means openings (101, 108) are aligned along the longitudinal axis of the shaft (98).

10. A bone plate (100) according to claim 1, wherein the plurality of fastening means openings (101, 102, 103, 108) are round or oblong in shape.

11. A bone plate (100) according to claim 1, wherein the insertion cavity (109) is gourd-shaped, pear-shaped or kidney-shaped.

12. A bone plate (100) according to claim 1, wherein a chamfer (200) is outwardly formed around the insertion cavity (109) toward its bottom surface (95) to allow maximum reach of a bone grafting device at any angle through the cavity (109).

13. A bone plate (100) according to claim 1 made of titanium, titanium alloy or stainless steel.

14. A kit (300) for fixing distal radius (405) fracture comprising:

a bone plate having a volar-shaped head (99) to be positioned at the distal radius (405); a shaft (98) inclinedly extending from the head (99); a plurality of K-wire openings (111) distributed over the head (99) for receiving K-wires (118) to temporarily secure the plate (100); and a plurality of fastening means openings (101, 102, 103, 108) distributed over the head (99) and the shaft (98) for receiving fastening means (104, 105, 106, 107) to fix the plate (100) to the distal radius (405); characterized by an insertion cavity (109) formed at the junction of the head (9.9) and the shaft (98) in such a manner as to provide an accessible space for efficient insertion of bone graft material;

a plurality of K-wires (118); and

a plurality of fastening means (104, 105, 106, 107).
