Abstract

System, including methods, apparatus, and kits, for bone fixation using a fixation device including a mounting portion and a fastener that attaches to the mounting portion. In some embodiments, the fixation device may include first and second mounting portions configured to be disposed across a bone from each other and secured with a fastener that extends from one of the mounting portions, through the bone, and to the other mounting portion. The system also may include a tool to facilitate installation of the fixation device.

Claims

1. A system for bone fixation, comprising:

a clip member including a first mounting portion and a second mounting portion facing each other and interconnected by a collapsible portion, the clip member being configured to be placed onto a bone such that the bone extends through the clip member;

wherein the clip member is configured to deform plastically at the collapsible portion when the mounting portions are urged toward each other,

wherein the collapsible portion includes a connecting member that extends from the first mounting portion to the second mounting portion,

wherein the connecting member has an inner surface region to face the bone and an outer surface region opposite the inner surface region,

wherein the connecting member also has a pair of lateral wall regions opposite one another and each extending from the inner surface region to the outer surface region, and

wherein the connecting member has a greater average width across the connecting member between the inner and outer surface regions than between the pair of lateral walls regions; and

wherein the clip member is a first clip member, further comprising a fixation device including the first clip member, a spanning portion, and a second clip member, and wherein the spanning portion is configured to extend along the bone from the first clip member to the second clip member after each clip member is secured to the bone.

2. The system of claim 1, wherein the connecting member is configured to fold when the mounting portions are urged toward each other.

3. The system of claim 1, wherein the connecting member is configured to deform at one or more predefined sites when the mounting portions are urged toward each other.

4. The system of claim 1, wherein the collapsible portion includes a pair of connecting members each separately interconnecting the first and second mounting portions.

5. The system of claim 1, wherein the first mounting portion and the second mounting portion respectively define a first aperture and a second aperture, and wherein the first aperture and the second aperture are configured to receive regions of a same linear fastener.

6. The system of claim 1, wherein the first mounting portion, the second mounting portion, and the collapsible portion are each formed integrally with one another.

7. The system of claim 1, wherein the connecting member extends along a three-dimensional path between the first mounting portion and the second mounting portion.

8. The system of claim 1, wherein a through-axis of the clip member is located intermediate the first mounting portion and the second mounting portion and is spaced from the collapsible portion, wherein the clip member is configured to be placed onto a bone such that the bone extends through the clip member along the through-axis, and wherein a distance between the connecting member and a plane orthogonal to the through-axis varies as the connecting member extends from the first mounting portion to the second mounting portion.

9. A system for bone fixation, comprising;

a clip member including a first mounting portion and a second mounting portion facing each other and interconnected by a collapsible portion;

wherein a through-axis of the clip member is located intermediate the first mounting portion and the second mounting portion and spaced from the collapsible portion,

wherein the clip member is configured to be placed onto a bone such that the bone extends through the clip member along the through-axis,

wherein, with the through-axis horizontal and the collapsible portion above the first and second mounting portions, an orthogonal projection of the collapsible portion onto a horizontal plane has a nonlinear region that defines an angle, and

wherein the collapsible portion is configured to deform plastically as the mounting portions are urged toward each other such that the angle defined by the nonlinear region decreases in the orthogonal projection; and

wherein the fixation device includes the clip member and a spanning portion, wherein the spanning portion is configured to extend along the bone from the first mounting portion after the first mounting portion is secured to the bone.

10. The system of claim 9, wherein the collapsible portion is configured to deform at one or more predefined sites when the mounting portions are urged toward each other.

11. The system of claim 9, wherein the collapsible portion includes a pair of elongate members each separately interconnecting the first and second mounting portions.

12. The system of claim 9, wherein the first mounting portion and the second mounting portion respectively define a first aperture and a second aperture, and wherein the first aperture and the second aperture are configured to receive regions of a same linear fastener.

13. The system of claim 9, wherein the first mounting portion, the second mounting portion, and the collapsible portion are formed integrally with one another.

14. A system for bone fixation, comprising:

a clip member including a first mounting portion and a second mounting portion facing each other and interconnected by a connecting member;

wherein a through-axis of the clip member is located intermediate the first mounting portion and the second mounting portion and spaced from the connecting member,

wherein the clip member is configured to be placed onto a bone such that the bone extends through the clip member along the through-axis,

wherein a central plane of the clip member is orthogonal to the through-axis, and

wherein the clip member is configured to deform plastically at the connecting member when the mounting portions are urged toward each other, to change a distance between at least one region of the connecting member and the central plane; and

wherein the fixation device includes the clip member and a spanning portion, wherein the spanning portion is configured to extend along the bone from the first mounting portion after the first mounting portion is secured to the bone.

15. The system of claim 14, wherein the connecting member has an inner surface region to face the bone and an outer surface region opposite the inner surface region, wherein the connecting member also has a pair of lateral wall regions opposite one another and each extending from the inner surface region to the outer surface region, and wherein the connecting member has a greater average width across the connecting member between the inner and outer surface regions than between the pair of lateral walls regions.

16. A system for bone fixation, comprising:

a clip member including a first mounting portion and a second mounting portion facing each other and interconnected by a connecting member;

wherein a through-axis of the clip member is located intermediate the first mounting portion and the second mounting portion and spaced from the connecting member,

wherein the clip member is configured to be placed onto a bone such that the bone extends through the clip member along the through-axis,

wherein a distance between the connecting member and a plane orthogonal to the through-axis varies as the connecting member extends from the first mounting portion to the second mounting portion, and

wherein the clip member is configured to deform plastically at the connecting member when the mounting portions are urged toward each other; and

wherein the fixation device includes the clip member and a spanning portion, wherein the spanning portion is configured to extend along the bone from the first mounting portion after the first mounting portion is secured to the bone.

17. The system of claim 16, wherein the connecting member extends along a three-dimensional path between the first mounting portion and the second mounting portion.
