An osteotomy implant includes a first surface extending generally in a first plane and a second surface extending generally in a second plane, oblique to the first plane. The first surface has a perimeter having a first linear edge, a first curve edge connected to the first linear edge, a second linear edge connected to the first curved edge, and a second curved edge connected to the second liner edge.

An expandable interspinous process fixation system capable of restoring spinal stability and facilitating fusion. In one embodiment, the expandable interspinous process fixation system includes a central ramp, a first endplate, and a second endplate, the central ramp capable of being moved in a first direction to move the first and second endplates outwardly and into an expanded configuration. Each endplate supporting fixed and/or adjustable spinous process engaging plates.

The present invention relates to an expandable implant for engagement between vertebrae generally comprising an inner member, outer member, and gear member positioned coaxial with respect to each other such that the inner and outer members are moveable relative to each other along an axis. The gear member is axially fixed to the outer member and freely rotatable with respect to the outer member and the gear member threadedly engages a threaded portion of the inner member to translate inner member along the axis. The implant is configured to engage the vertebrae in a predetermined alignment and the gear member includes gear teeth exposed to the exterior and configured to be accessible by a tool member at a plurality of angular positions around the perimeter of the implant device.

Embodiments herein are generally directed to expandable spinal implants, systems, apparatuses, and components thereof that can be used in spinal fusion and/or stabilization procedures, as well as methods of installation. The expandable spinal implants may be configured for lateral insertion.

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a body portion, a first endplate, and a second endplate, the first and second endplates capable of being moved in a direction away from the body portion into an expanded configuration or capable of being moved towards the body portion into an unexpanded configuration. The fusion device is capable of being deployed and installed in both configurations.

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a central ramp, a first endplate, and a second endplate, the central ramp capable of being moved in a first direction to move the first and second endplates outwardly and into an expanded configuration. The fusion device is capable of being deployed down an endoscopic tube.

A spinal implant system is provided for bridging an intervertebral space between vertebral bodies bordering the intervertebral space. The spinal implant system includes at least one adjustable end cap and a spinal implant. The end cap can be used with additional end caps and/or the spinal implant. Multiple end caps can be stacked on top of one another, and one end cap can be attached to a first end of the spinal implant, and another end cap can be attached to a second end of the spinal implant. Thus, one or more of the end caps can be attached to either end of the spinal implant.

A stand-alone expandable interbody spinal fusion device, including a superior component, an inferior component, and an expansion mechanism operatively arranged to displace the superior component relative to the inferior component, the expansion mechanism including a threaded rod including a first end engaged with the superior component and a second end engaged with the inferior component, wherein when the threaded rod is rotated in a first circumferential direction, the superior component is displaced in a first direction relative to the inferior component.

This disclosure includes an expansion driver for adjusting expandable implants, the expansion drivers includes: a first driver having a first gear disposed at a first end thereof; and a second driver having a second gear disposed at a first end of the second driver; and a handle operably connected to the first driver and the second driver, the handle having at least one bevel gear rotatably attached thereto, the at least one bevel gear engaging each of the first gear and the second gear; wherein upon a rotation of the handle a torque is applied to at least one of the first driver or the second driver.

A dilation introducer for orthopedic surgery is provided for minimally invasive access for insertion of an intervertebral implant. The dilation introducer may be used to provide an access position through Kambin's triangle from a posterolateral approach. A first dilator tube with a first longitudinal axis is provided. A second dilator tube may be introduced over the first, advanced along a second longitudinal axis parallel to but offset from the first. A third dilator tube may be introduced over the second, advanced along a third longitudinal axis parallel to but offset from both the first and the second. An access cannula may be introduced over the third dilator tube. With the first, second, and third dilator tubes removed, surgical instruments may pass through the access cannula to operate on an intervertebral disc and/or insert an intervertebral implant.
