## Abstract

A modular, customizable system that provides components for assembling an implantable device is provided. The system allows the user to assemble an implantable spine stabilization device that is flexible and allows dynamic stabilization. The same system also provides components for assembling a rigid or non-flexible fusion-enabling spine stabilization device. The components of the system are easily interchangeable, allowing the user the ability to customize the assembled device for a true fit with the patient, as well as allow an easy conversion of the dynamic device into a fusion-enabling device. Associated insertion instruments and methods of use are also disclosed.

## Claims

### Claim 1

An implantable spine stabilization device comprising:
a main body having a superior plate, inferior plate, and a flexible sidewall connecting the superior and inferior plates, the superior plate having an opening extending therethrough; and
a domed cap comprising a domed top and a stem extending from the domed top, the stem being configured for snap-fit engagement with the opening on the superior plate;
wherein the main body is compressible and distractable.

### Claim 2 (depends on 1)

The device of claim 1, wherein at least one of the main body and the domed cap comprises surface features for anchorage to bone tissue.

### Claim 3 (depends on 2)

The device of claim 2, wherein the surface features comprise teeth, ridges, spikes, or roughened surfaces.

### Claim 4 (depends on 1)

The device of claim 1, wherein the superior plate has a panel extending from an underside thereof, the panel including at least one tool-engaging opening.

### Claim 5 (depends on 1)

The device of claim 1, wherein the domed cap may be eccentric or centric, and is attachable to the superior plate in different orientations.

### Claim 6 (depends on 1)

The device of claim 1, further including a cap attached to the inferior plate.

### Claim 7 (depends on 1)

The device of claim 1, wherein the domed cap comprises a bioactive coating for promoting fusion to anchor to bone tissue.

### Claim 8 (depends on 1)

The device of claim 1, wherein the stem comprises movable fingers.

### Claim 9

An implantable spine stabilization device comprising:
a compressible and distractable main body having a superior plate, inferior plate, and a flexible sidewall connecting the superior and inferior plates, the superior plate having an opening extending therethrough, and a domed cap comprising a domed top and a stem extending from the domed top and configured for snap-fit engagement with the opening on the superior plate, the domed top including a through-hole; and
a compression-blocking insert configured for placement in between the superior and inferior plates, the insert being sized to fit entirely within the main body.

### Claim 10 (depends on 9)

The device of claim 9, wherein the opening of the superior plate and through-hole of the domed cap align to create a receiving channel when the domed cap is attached to the superior plate.

### Claim 11 (depends on 10)

The device of claim 10, further including bone graft material, bone cement, bone void filler, bone substitute material, bone hardening material, bone chips, or demineralized bone matrix for insertion into the receiving channel.

### Claim 12 (depends on 9)

The device of claim 9, wherein at least one of the main body and domed cap includes surface features for anchorage to bone tissue.

### Claim 13 (depends on 12)

The device of claim 12, wherein the surface features comprise teeth, ridges, spikes, or roughened surfaces.

### Claim 14 (depends on 9)

The device of claim 9, wherein the superior plate has a panel extending from an underside thereof, the panel including at least one tool-engaging opening.

### Claim 15 (depends on 14)

The device of claim 14, wherein the panel further includes a cutaway slot for allowing passage of the compression-blocking insert into the main body.

### Claim 16 (depends on 9)

The device of claim 9, wherein the domed cap may be eccentric or centric, and is attachable to the superior plate in different orientations.

### Claim 17 (depends on 9)

The device of claim 9, further including a cap attached to the inferior plate.

### Claim 18 (depends on 9)

The device of claim 9, wherein the domed cap comprises a bioactive coating for promoting fusion to anchor to bone tissue.

### Claim 19 (depends on 9)

The device of claim 9, wherein the insert comprises an attachment plate for securing the device to vertebral bodies.

### Claim 20 (depends on 9)

The device of claim 9, further comprising screw holes for receiving fixation screws.

### Claim 21 (depends on 9)

The device of claim 9, wherein the stem comprises movable fingers.
