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 treating a sacroiliac joint at a sacroiliac joint region having a sacrum, an ilium and a sacroiliac joint space therebetween, the method comprising: a) delivering a joint implant into the sacroiliac joint region, the joint implant comprising a body including a length extending between a proximal end and a distal end, an external surface extending the length, and a fixation member receiving channel extending the length and disposed in the external surface; and b) delivering a fixation member into the fixation member receiving channel thereby forming a joint implant assembly, the fixation member slidingly and matingly engaging the fixation member receiving channel in a grooved arrangement, wherein, when the fixation member is received into the fixation member receiving channel, the fixation member extends outward from the external surface of the joint implant and extends a portion of the length.

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.

A spinal joint distraction system for treating a facet joint including articular surfaces having a contour is disclosed and may include a delivery device including a generally tubular structure adapted to engage a facet joint, an implant adapted to be delivered through the delivery device and into the facet joint, the implant comprising two members arranged in opposed position, and an implant distractor comprising a generally elongate member adapted to advance between the two members of the implant causing separation of the members and distraction of the facet joint, wherein the implant is adapted to conform to the shape of the implant distractor and/or the articular surfaces of the facet upon being delivered to the facet joint. Several embodiments of a system, several embodiments of an implant, and several methods are disclosed including a method for interbody fusion.

A method of surgically treating a patient suffering from severe pain and disability of the low back and buttock by stabilizing the patient's spinal column to their pelvis with an implant system including surgical tools and an implant designed to prevent movement between the sacrum and the ilium while being able to attach to a spinal fusion rod which connect to pedicle screws implanted in the bones of the spine of the patient in order to offer lasting relief of the patient's symptoms. The system is designed to address complications in adult spinal deformity by optimizing spinopelvic fixation vis-?-vis the unique biomechanics of the SI joint. The sacropelvic system is a surgical solution which provides an additively manufactured implant at the base of the spine employing an S2AI trajectory while utilizing assisting technologies including surgical navigation and intraoperative neurophysiological monitoring.

A device for insertion into a gap between adjacent, spaced apart bony elements includes an adjustable length interconnecting member having a distal and a proximal retention plate secured to opposite ends of the interconnecting member. The distal retention plate has a non-rotated position and a plurality of rotated positions. The non-rotated position aligns the distal retention plate with the gap prior to and during insertion of the distal retention plate into the gap. The distal retention plate is rotated after it has exited the gap on a distal side of the gap to prevent its return into the gap. The proximal retention plate is misaligned with the gap so that it cannot enter into the gap. The rotated distal retention plate cooperates with the proximal retention plate to hold bony elements such as adjacent vertebral bodies in a stable relationship to one another when the interconnecting member is shortened.

An expandable fusion device may include a first endplate and a second endplate. The expandable fusion device may also include first and second ramps configured to mate with both the first and second endplates. The first ramp may include a mating feature having a first angle relative to a vertical axis, and the second ramp may include a mating feature having a second angle relative to the vertical axis such that the first angle is different from the second angle. In particular, the first and second ramps may be configured to provide for symmetrical expansion of the first and second endplates.

A spinal distraction system, according to one aspect, includes an adjustable spinal distraction rod comprising first and second members, the adjustable spinal distraction rod configured for non-invasive elongation of the first and second members. The system includes an anchor rod configured for mounting to a bone of a subject, the anchor rod having one or more spring-biased tabs disposed at one end thereof, and a connector having first end and a second end, the first end having a receiving cup configured for detachable mounting on the anchor rod, wherein the one or more spring-biased tabs are configured to engage with an inner surface of the receiving cup, the connector having a second end operatively coupled to an end of a first member and wherein the second member is configured for mounting to a second bone of a subject.

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 body, a first endplate, and a second endplate, a middle ramp piece, a stem, and two ramp pins. The middle ramped piece is operable to move to generate lordotic expansion of the first and second endplates followed by parallel expansion. The fusion device is operable to be deployed down an endoscopic tube.

An example expandable interbody device can include a structural body having an upper endplate and a lower endplate, where the endplates are shaped to nest tightly in a closed position. The device can include at least one wedge block and at least one linkage block arranged between the upper and lower endplates of the structural body. The device can include a drive screw threaded through the at least one wedge block and the at least one linkage block. The drive screw can be configured to rotate and drive the at least one wedge block to expand the upper and lower endplates of the structural body from the closed position to an intermediate position. Additionally, the drive screw can be further configured to rotate and drive the at least one linkage block to expand the upper and lower endplates of the structural body from the intermediate position to an open position.
