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 method for fixating a dysfunctional sacroiliac joint including implanting a joint implant at the sacroiliac joint. The joint implant may include: a length extending between a proximal end and a distal end; an exterior surface extending the length; an interior surface opposite the exterior surface and extending the length, the interior surface defining an internal volume therein; a wall thickness defined between the external surface and the interior surface; a proximal opening extending into the internal volume; a first wall section comprising a first plurality of struts arranged along the length and defining a first plurality of openings extending through the wall thickness; and a second wall section including a second plurality of struts arranged along the length and defining a second plurality of opening extending through the wall thickness. Each opening of the first and second plurality of openings may be generally polygonal in shape.

A method for fixating a dysfunctional sacroiliac joint for SI joint fusion including implanting a joint implant at the sacroiliac joint. The joint implant may include a body extending a length between a proximal end and a distal end, an exterior surface, an interior surface opposite the exterior surface and defining an internal volume therein, a wall thickness extending between the exterior surface and the interior surface, a proximal opening extending into the internal volume, and a first plurality of voids along the length and extending through the wall thickness from the exterior surface to the interior surface. The first plurality of voids may be arranged along the length in a repeating pattern of a group of voids, wherein each void of the first plurality of voids is generally polygonal in shape.

An expandable implant for engagement between vertebrae includes an inner member, an outer member, and a 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 inner member includes a longitudinal groove configured to engage a pin extending through the outer member such that the pin prevents the inner member from translating completely through the outer member and aids in alignment and limits rotation of the second endplate. Portions of the implant may be provided with a series of markings such that when the markings are aligned, the implant is aligned in a specific configuration and for a specific implantation approach.

A sacroiliac joint fusion system that provides a method of fixation and fusion of the sacroiliac joint and sacroiliac fixation fusion implant which upon placement facilitates stability and fusion of the sacroiliac joint.

A method for preparing a sacroiliac joint for stabilization which may include approaching a posterior aspect of the sacroiliac joint inferior to a PSIS with a defect-creating tool assembly, creating a defect in the sacrum and the ilium defined by at least one noncircular cross-sectional shape, delivering an implant having a body with a length extending between proximal and distal ends, the body including at least one cylindrical body with a longitudinal axis and an opening at the proximal end aligned with the longitudinal axis of the cylindrical body, a pattern of openings spaced along the cylindrical body and a planar member coupled with and extending along the cylindrical body. The implant may be implanted with the length generally following a plane of the sacroiliac joint such that it is advanced from a generally posterior to anterior approach while the body of the implant bridges the joint.

A method of fusing a sacroiliac joint including a sacrum, an ilium, and a sacroiliac joint space defined therebetween. The method may include: approaching a posterior aspect of the sacroiliac joint space with a joint implant including a body extending a length between a distal end and a proximal end; and delivering the joint implant into the sacroiliac joint space such that the joint implant passes through an access region defined between the posterior superior iliac spine and the posterior inferior iliac spine. The joint implant may be oriented in the sacroiliac joint space such that a portion of the body of the joint implant is positioned within a joint plane of the sacroiliac joint space, and such that the distal end of the joint implant is positioned posteriorly of an anterior boundary of the sacroiliac joint space.

A spinal distractor and stabilizer has resilient, conformable bone contacting sections which are separated by an expandable chamber that extends from one of the sections, and which forms a ratchet with the section, ensuring that once expanded by being filled with a substance, cannot contract absent intervention by a medical practitioner. The stabilizer may be filled with a material which solidifies, after which some or all of the device may biodegrade. The device may also be provided in separable portions to facilitate implantation. The conformable sections distribute the distraction and stabilizing force evenly over the bone surface, reducing the incidence of disruption to the integrity of the bone.

An expandable fusion device is capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. The fusion device may include 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.

A modular implant for performing an intervertebral fusion on adjacent vertebral bodies in a patient including a first spacer portion, a second spacer and a container having a first end and a second end, the first end of the container constructed to operably engage a first spacer and the second end of the container constructed to operably engage the second spacer.
