Systems and methods for distracting an intervertebral disc space are provided. The systems use an expandable trial with telescopic stabilizers. The systems and methods of distracting an intervertebral space are provided in a manner that addresses the problem of subsidence. The method includes inserting the trial into the intervertebral space in a collapsed state and, once inserted, the trial is then used for distracting the intervertebral space using an expansion that includes a first stage and a second stage. The first stage includes expanding the trial laterally toward the peripheral zones of the top vertebral plate and the bottom vertebral plate, and the second stage includes expanding the trial vertically to distract the intervertebral space.

One implementation of the present disclosure may include a method of sacroiliac joint fusion involving a joint implant and a delivery tool. The joint implant includes at least one integral anchor configured to move relative to a body of the implant when being brought into anchoring engagement with bone defining a sacroiliac joint space in which the body of the implant is located. In certain embodiments, the anchor extends distally and laterally relative to a body of the implant or the anchor rotates relative to the body of the implant via a center axle when being brought into anchoring engagement with the bone. The delivery tool may be configured to support the implant and to cause the displacement of the at least one anchor relative to the implant body so as to cause the at least one anchor to be brought into anchoring engagement with the bone.

A delivery device includes a guide tool and an impact tool. The guide tool includes an elongate body formed with a longitudinal guide channel, whose inner perimeter is made to complement an outer contour of an implant. The elongate body is formed with a longitudinal impact-tool channel, whose inner perimeter is made to complement an outer contour of the impact tool.

A spinal facet fusion implant comprising: an elongated body having a distal end, a proximal end and a longitudinal axis extending between the distal end and the proximal end, the elongated body being characterized by a superior body surface and an inferior body surface; a superior stabilizer extending outwardly from the superior body surface, the superior stabilizer being characterized by a superior stabilizer surface; and an inferior stabilizer extending outwardly from the inferior body surface, the inferior stabilizer being characterized by an inferior stabilizer surface; wherein (i) the superior body surface and the inferior body surface are tapered relative to one another, and/or (ii) the superior stabilizer surface and the inferior stabilizer surface are tapered relative to one another.

Assemblies of one or more implant structures make possible the achievement of diverse interventions involving the fusion and/or stabilization of the SI-joint and/or lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. The representative lumbar spine interventions, which can be performed on adults or children, include, but are not limited to, SI-joint fusion or fixation; lumbar interbody fusion; translaminar lumbar fusion; lumbar facet fusion; trans-iliac lumbar fusion; and the stabilization of a spondylolisthesis.

A system for performing a minimally invasive interventional fusion procedure on a sacroiliac joint of a patient. The system may include a disposable sterile packed implant and kit including access, bone cutting, accessory and extraction instruments.

Intervertebral spacer implants with dynamic load spreading features responsive to external loads and having attachment mechanisms. The dynamic load spreading features having a native state and a loaded state, which complements vertebral end plate geometry and disperses load to the epiphyseal rim.

A method of fusing a sacroiliac joint including: a) approaching a posterior aspect of a sacroiliac joint space with a joint implant including a body extending a length between a distal end and a proximal end; and b) delivering the joint implant into the sacroiliac joint space such that the joint implant passes through an access region defined between a posterior superior iliac spine and a posterior inferior iliac spine, the joint implant being 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.

An implant for interbody fusion of vertebrae comprising a unibody cage structure having an enveloping cage volume and a minimized material volume. The cage structure comprises a first and a second generally planar ring member, each ring member formed from an opposing pair of lengthwise joists and an opposing pair of cross joists, the joists together forming a large opening through the ring member. The ring members are fixedly sandwiched on a plurality of support members, the support members holding the ring members in a spaced apart relationship to thereby provide a large void volume relative to the enveloping cage volume, to thereby allow for receipt of a large volume of bone graft within the cage structure.

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.
