Abstract

Devices, systems, and methods for bone stabilization, especially volar distal radius stabilization. The stabilization system may include a bone plate having an elongated portion, an enlarged head portion, and a transition region connecting the elongated portion to the enlarged head portion, and the plate including a plurality of through holes. A plurality of fasteners may be configured to extend through one or more of the plurality of through holes in the bone plate and into the bone. The plate may be used to stabilize a fracture in a long bone, such as a radius.

First claim

What is claimed is:

1. A stabilization system for stabilizing a bone, the system comprising:
a bone plate, the bone plate comprising an elongated portion extending along a longitudinal axis, an enlarged head portion extending along an axis from a first end to a second end, the first end being laterally offset and extending a first distance from the longitudinal axis in a first lateral direction, and the second end being laterally offset and extending a second distance from the longitudinal axis in a second lateral direction opposite to the first lateral direction, the axis of the enlarged head portion being angled relative to the longitudinal axis of the elongated portion, and a transition region connecting the elongated portion to the enlarged head portion, wherein the transition region is curved and connected to the first end, and the second end of the enlarged head portion is a free end, the bone plate comprising a plurality of through holes extending through the enlarged head portion, the transition region, and the elongated portion; and
a plurality of fasteners configured to extend through one or more of the plurality of through holes in the bone plate and configured to secure the bone plate to the bone.

2. The stabilization system of claim 1 , wherein the plurality of through holes includes a first plurality of fixed angle holes positioned in general alignment along the elongated portion, and the plurality of fasteners include a plurality of fixed angle fasteners configured to be received in the fixed angle holes, the plurality of fixed angle fasteners capable of being received along a single predetermined trajectory in the fixed angle holes.

3. The stabilization system of claim 1 , wherein the plurality of through holes includes a polyaxial hole positioned proximate to the first end of the enlarged head portion connected to the transition region, and the plurality of fasteners include a polyaxial fastener configured to be received in the polyaxial hole, the polyaxial fastener capable of being received along a plurality of trajectories in the polyaxial hole.

4. The stabilization system of claim 1 , wherein the plurality of through holes includes an elongated slot on the elongated portion, and the plurality of fasteners include a fastener configured to be received in the elongated slot, wherein the elongated slot allows for proximal-distal and medial-lateral adjustment of the plate.

5. The stabilization system of claim 1 , wherein the transition region extends at an angle relative to the longitudinal axis.

6. The stabilization system of claim 1 , wherein the enlarged head portion extends at an angle relative to the transition region.

7. The stabilization system of claim 1 , wherein the plurality of fasteners include fasteners having self-forming threads on a head portion of the fasteners, which are configured to lock to at least one of the plurality of through holes on the plate.

8. The stabilization system of claim 1 , wherein the plate further comprises a second plurality of openings configured ask-wire holes to receive one or more k-wires.

9. The stabilization system of claim 1 , wherein the plate includes a plurality of recesses located along the elongated portion between the through holes, and the plurality of recesses are configured to facilitate bending of the plate.

10. A stabilization system configured to stabilize a radius, the system comprising:
a bone plate, the bone plate comprising an elongated portion extending along a longitudinal axis, an enlarged head portion extending along an axis from a first end to a second end, the first end being a first outermost lateral portion in a first direction transverse to the longitudinal axis and the second end being a second outermost lateral portion in a second direction transverse to the longitudinal axis and opposite to the first direction, the axis of the enlarged head portion being angled relative to the longitudinal axis of the elongated portion, and a transition region connecting the elongated portion to the enlarged head portion, wherein the transition region is curved and connected to the first end, and the second end of the enlarged head portion is a free end, the bone plate comprising a plurality of fixed angle holes positioned in general alignment along the elongated portion, a polyaxial hole positioned proximate to the first end of the enlarged head portion connected to the transition region, and an elongated slot on the elongated portion;
a plurality of fixed angle fasteners configured to be received in the fixed angle holes, the plurality of fixed angle fasteners capable of being received along a single predetermined trajectory in the fixed angle hole;
a polyaxial fastener configured to be received in the polyaxial hole, the polyaxial fastener capable of being received along a plurality of trajectories in the polyaxial hole; and
a fastener configured to be received in the elongated slot, wherein the elongated slot allows for proximal-distal and medial-lateral adjustment of the plate.

11. The stabilization system of claim 10 , wherein the transition region extends at an angle relative to the longitudinal axis.

12. The stabilization system of claim 10 , wherein the enlarged head portion extends at an angle relative to the transition region.

13. The stabilization system of claim 10 , wherein the plurality of fasteners include fasteners having self-forming threads on a head portion of the fasteners, which are configured to lock to at least one of the plurality of through holes on the plate.

14. The stabilization system of claim 10 , wherein the plate further comprises a second plurality of openings configured as k-wire holes to receive one or more k-wires.

15. The stabilization system of claim 10 , wherein the plate includes a plurality recesses located along the elongated portion between the through holes, and the plurality of recesses are configured to facilitate bending of the plate.

16. A stabilization system for stabilizing a bone, the system comprising:
a bone plate having an upper surface and a lower surface configured to contact the bone, wherein the lower surface comprises one or more recesses configured to reduce contact between the plate and a surface of the bone, the bone plate comprising an elongated portion extending along a longitudinal axis and having a first lateral side and a second lateral side opposite to the first lateral side, an enlarged head portion extending along an axis from a first end to a second end, the first end extending laterally outward relative to the first lateral side of the elongate portion, and the second end extending laterally outward relative to the second lateral side of the elongate portion, the axis of the enlarged head portion being angled relative to the longitudinal axis of the elongated portion, and a transition region connecting the elongated portion to the enlarged head portion, wherein the transition region is connected to the first end of the enlarged head portion, and the second end of the enlarged head portion is a free end, the bone plate comprising a plurality of through holes extending through the enlarged head portion, the transition region, and the elongated portion; and
a plurality of fasteners configured to extend through one or more of the plurality of through holes in the bone plate and configured to secure the bone plate to the bone.

17. The stabilization system of claim 16 , wherein the transition region extends at an angle relative to the longitudinal axis.

18. The stabilization system of claim 16 , wherein the enlarged head portion e
