System for treating bone fractures
According to one example embodiment, a radius fixation plate includes a body portion configured to conform to a radius bone between a first extensor compartment and a second extensor compartment and dimensioned such that the body portion does not violate the first extensor compartment or the second extensor compartment. A first fixation device is configured to traverse through a first opening of the body portion and engage at least part of a radial styloid of the radius bone.
1. A radius fixation plate comprising:
a body portion configured to conform to a radius bone between a first extensor compartment and a second extensor compartment and dimensioned such that an entirety of the radius fixation plate, as defined by the body portion, does not violate the first extensor compartment and does not violate the second extensor compartment;
a first opening through the body portion, the first opening configured to receive a first fixation device, the first fixation device configured to traverse through the first opening and engage at least part of a radial styloid of the radius bone;
a second opening through the body portion, the second opening configured to receive a second fixation device, the second fixation device configured to traverse through the second opening and engage at least part of a subchondral region of the radius bone; and
a third opening through the body portion, the third opening configured to receive a third fixation device, the third fixation device configured to traverse through the third opening and engage at least part of a subchondral region of the radius bone.
2. A radius fixation plate comprising:
a body portion configured to conform to a radius bone between a first extensor compartment and a second extensor compartment and dimensioned such that the body portion does not violate the first extensor compartment and does not violate the second extensor compartment;
a first opening through the body portion, the first opening configured to receive a first fixation device, the first fixation device configured to traverse through the first opening ad engage at least part of a radial styloid of the radius bone;
a second opening though the body portion, the second opening configured to receive a second fixation device, the second fixation device configured to traverse through the second opening and engage at least part of a subchondral region of the radius bone; and
a third opening through the body portion, the third opening configured to receive a third fixation device, the third fixation device configured to traverse through the third opening and engage at least part of a subchondral region of the radius bone, the first opening distal to the second opening and the third opening, the second opening spacing the first opening from the third opening, the first fixation device when installed extending past the second opening, the third opening and an end of the body portion.
3. The radius fixation plate of claim 1 ,
wherein,
the first opening is oriented relative to the second opening and the third opening such that the first fixation device when installed passes between the second fixation device and the third fixation device when installed.
4. The radius fixation plate of claim 1 , further comprising:
a Kirschner wire hole through the body portion.
5. The radius fixation plate of claim 1 ,
wherein,
the body portion includes an apex region configured to conform to the radius bone proximate to an intersection of tendons in the first extensor compartment and tendons in the second extensor compartment.
6. The radius fixation plate of claim 1 ,
wherein,
the first opening is a threaded opening.
7. The radius fixation plate of claim 1 , wherein the body portion is defined by a curved distal end portion and to a tapered portion extending from the curved distal end portion.
8. The radius fixation plate of claim 7 , wherein the tapered portion includes a continuous taper, on each side of the body portion, extending between at least the first opening and the third opening.
9. The radius fixation plate of claim 7 ,
wherein,
the tapered portion is defined by converging sides of the body portion forming a V-shape,
the converging sides prevent the body portion from extending over the first extensor compartment and the second extensor compartment.
10. The radius fixation plate of claim 7 , wherein the curved distal end portion adjoins the tapered portion at points on each side of the first opening, with an imaginary straight line connecting the points and extending across the first opening.
11. The radius fixation plate of claim 1 ,
wherein,
the first opening and the third opening are on opposite ends of the body portion,
the first opening is at a distal end of the body portion, and
the third opening is at a proximal end of the body portion.
12. The radius fixation plate of claim 2 , wherein the first opening is oriented relative to the second opening and the third opening such that the first fixation device when installed passes between the second fixation device and the third fixation device when installed.
13. The radius fixation plate of claim 2 , wherein the body portion forms an entirety of the radius fixation plate.
14. The radius fixation plate of claim 2 , wherein an entirety of the body portion has a substantially uniform thickness formed in a crescent shape.
15. The radius fixation plate of claim 2 , wherein the body portion includes a widest portion adjacent to the first opening and a narrowest portion adjacent to the third opening on an opposite side of the body portion relative to the first opening.
16. The radius fixation plate of claim 2 ,
wherein,
the body portion is partially defined by a tapered portion,
the tapered portion includes converging sides of the body portion, and
the converging sides prevent the radius fixation plate from extending over the first extensor compartment and the second extensor compartment.
