## 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

### Claim 1

A system for bone fixation, comprising:
a fixation device including a first mounting portion and a second mounting portion facing each other and interconnected by a collapsible portion configured to collapse when the mounting portions are urged toward each other.

### Claim 2 (depends on 1)

The system of claim 1, wherein the collapsible portion includes an elongate member configured to fold when the mounting portions are urged toward each other.

### Claim 3 (depends on 2)

The system of claim 2, wherein the elongate member is configured to fold at one or more predefined sites when the mounting portions are urged toward each other.

### Claim 4 (depends on 2)

The system of claim 2, wherein the collapsible portion includes a pair of elongate members each separately interconnecting the first and second mounting portions.

### Claim 5 (depends on 1)

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.

### Claim 6 (depends on 1)

The system of claim 1, wherein the fixation device includes a spanning portion, and 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.

### Claim 7 (depends on 1)

The system of claim 1, wherein the fixation device includes a clip member, and wherein the first mounting portion, the second mounting portion, and the collapsible portion are each formed integrally as part of the clip member.

### Claim 8 (depends on 1)

The system of claim 1, wherein at least one of the first and second mounting portions includes a slot defining a long axis and having a first side wall region and a second side wall region arranged on opposite sides of the long axis from each other, the first side wall region defining a pair of ridges that extend along the slot and form a pair of crests, wherein a groove is defined by the first side wall region between the pair of crests,
the system further comprising a fastener having a thread and being advanceable into the slot to interchangeably attach the fastener to the slot in a first configuration having a portion of the thread disposed in the groove and in a second configuration having the thread opposingly flanking the pair of ridges and not disposed in the groove.

### Claim 9 (depends on 1)

The system of claim 1, further comprising an installation tool having a proximal jaw and a distal jaw and being connectable to the fixation device such that the tool is operable to urge the first and second mounting portions toward each other with the jaws, to clamp the first and second mounting portions to the bone.

### Claim 10 (depends on 9)

The system of claim 9, wherein the first mounting portion defines a first aperture and the second mounting portion defines a second aperture, and wherein the first aperture and the second aperture are arranged on a same fastener-receiving axis.

### Claim 11 (depends on 10)

The system of claim 10, wherein the installation tool is configured to urge the first and second mounting portions toward each other while maintaining the first aperture and the second aperture on the fastener-receiving axis.

### Claim 12 (depends on 11)

The system of claim 11, wherein the second mounting portion is permitted to pivot with respect to the distal jaw as the collapsible region collapses.

### Claim 13 (depends on 10)

The system of claim 10, wherein the first jaw and the second jaw are configured to apply compression parallel to a compression axis, wherein a separation distance between the mounting portions is decreased as the mounting portions are urged toward each other, and wherein the fastener-receiving axis remains parallel to the compression axis as the separation distance decreases.

### Claim 14 (depends on 9)

The system of claim 9, wherein the installation tool is configured to apply compressive force parallel to a compression axis with the jaws, and wherein the tool is configured to be connected to the mounting portions such that each mounting portion is disposed at a predefined position along an axis orthogonal to the compression axis.

### Claim 15 (depends on 9)

The system of claim 9, wherein the installation tool is configured to guide placement of a same fastener into an aperture of the first mounting portion and an aperture of the second mounting portion while the first and second mounting portions remain clamped to the bone by the installation tool.

### Claim 16 (depends on 9)

The system of claim 9, wherein the installation tool includes a gauge configured to indicate a fastener of appropriate length for spanning the mounting portions after the collapsible portion collapses.

### Claim 17 (depends on 9)

The system of claim 9, wherein the installation tool includes a fastener that attaches the proximal jaw to the first mounting portion, wherein the second mounting portion defines an opening, and wherein the distal jaw defines a projection configured to be disposed at least partially in the opening.

### Claim 18

A system for bone fixation, comprising:
a fixation device including a clip member having a first mounting portion facing a second mounting portion, the first mounting portion including a slot defining a long axis and having a first side wall region and a second side wall region arranged on opposite sides of the long axis from each other, the first side wall region defining a pair of ridges that extend along the slot and form a pair of crests, wherein a groove being defined by the first side wall region between the pair of crests; and
a fastener having a thread and being advanceable into the slot to interchangeably attach the fastener to the slot in a first configuration having a portion of the thread disposed in the groove and in a second configuration having the thread opposingly flanking the pair of ridges and not disposed in the groove.

### Claim 19 (depends on 18)

The system of claim 18, wherein the second mounting portion defines an aperture, and wherein the fastener is configured to extend from the aperture to the slot.

### Claim 20 (depends on 19)

The system of claim 19, wherein the aperture has an internal thread for threaded engagement with the fastener.
