Abstract

An intervertebral process brace is disclosed and can include a frame that can support a first vertebral process and a second vertebral process. The intervertebral process brace can also include a first vertebral process support strap that can span a first portion of the frame. The first vertebral process support strap can engage the first vertebral process and bind the first vertebral process between the first vertebral process support strap and the first portion of the frame.

Claims

1. An intervertebral process brace, comprising:

a frame configured to support an upper vertebral process and a lower vertebral process, wherein the frame has;

an inwardly facing upper concave surface configured to extend around a superior surface of the upper vertebral process;

an opposing inwardly facing lower concave surface configured to extend around an inferior surface of the lower vertebral process;

an outwardly facing upper convex surface corresponding to the upper concave surface;

an outwardly facing lower convex surface corresponding to the lower concave surface;

the upper concave surface and the upper convex surface each having respective maximum points;

the lower concave surface and the lower convex surface each having respective minimum points;

the inwardly facing upper and lower concave surfaces and the outwardly facing upper and lower convex surfaces being integrally formed portions of the frame;

a first flexible vertebral process support strap spanning a first portion of the frame, wherein the first vertebral process support strap is configured to engage an inferior surface of the upper vertebral process and bind the upper vertebral process between the first vertebral process support strap and the first portion of the frame;

a locking collar attached on the first vertebral process support strap;

the locking collar being simultaneously movable relative to the frame and slidable along the first vertebral process support strap;

the locking collar operative to secure the first vertebral process support strap to the frame;

wherein when the intervertebral process brace is disposed such that the frame supports the upper and lower vertebral processes and the first strap engages an inferior surface of the upper vertebral process, the inwardly facing upper and lower concave surfaces and the outwardly facing upper and lower convex surfaces extend through a sagittal plane defined by the upper and lower vertebral processes such that the respective maximum points and the respective minimum points are disposed along the sagittal plane.

2. The intervertebral process brace of claim 1, further comprising:

a second vertebral process support strap spanning a second portion of the frame, wherein the second vertebral process support strap is configured to engage a superior surface of the lower vertebral process and bind the lower vertebral process between the second vertebral process support strap and the second portion of the frame.

3. The intervertebral process brace of claim 2, wherein the first vertebral process support strap and the second vertebral process support strap can be tightened relative to the frame to increase a distance between the upper vertebral process and the lower vertebral process.

4. The intervertebral process brace of claim 3, wherein the frame is generally ellipse-shaped, generally C-shaped, or a combination thereof.

5. The intervertebral process brace of claim 4, further comprising:

a first vertebral process engagement structure extending from the first portion of the frame toward a center of the frame.

6. The intervertebral process brace of claim 5, further comprising:

a second vertebral process engagement structure substantially opposite the first vertebral process engagement structure and extending from the second portion of the frame toward a center of the frame.

7. The intervertebral process brace of claim 1, wherein the upper vertebral process and the lower vertebral process are spinous processes of adjacent vertebrae.

8. An interspinous process brace, comprising:

a frame configured to be installed around a first spinous process and a second spinous process, the frame comprising;

an inwardly facing upper concave surface and an opposing inwardly facing lower concave surface;

an outwardly facing upper convex surface corresponding to the upper concave surface and an opposing outwardly facing lower convex surface corresponding to the lower concave surface, the inwardly facing upper and lower concave surfaces and the outwardly facing upper and lower convex surfaces being integrally formed portions of the frame;

the upper concave surface and the upper convex surface each having respective maximum points;

the lower concave surface and the lower convex surface each having respective minimum points;

a first spinous process support strap spanning a first portion of the frame and associated with the upper concave surface;

a second spinous process support strap spanning a second portion of the frame and associated with the lower concave surface;

a locking collar attached on the first spinous process support strap;

the locking collar being simultaneously movable relative to the frame and slidable along the first spinous process support strap;

the locking collar operative to secure the first spinous process support strap to the frame;

wherein the first spinous process support strap and the second spinous support strap can be moved relative to the frame to increase a distance between the first spinous process and the second spinous process;

wherein when the frame is installed around the first and second spinous processes, the inwardly facing upper and lower concave surfaces and the outwardly facing upper and lower convex surfaces extend through a sagittal plane defined by the first and second spinal processes such that the respective maximum points and the respective minimum points are disposed along the sagittal plane.
