Systems for and methods of fusing a sacroiliac joint are provided which include an implant assembly adapted to be inserted into the joint space defined by the bones of a sacrum and an ilium, a delivery tool and means for inserting the implant assembly into the joint. The implant assembly includes a body disposed intermediate distal and proximate end portions thereof and having oppositely disposed side members adapted to expandably engage the sacroiliac joint following insertion of the assembly into the joint space. A tool is provided and provides a means for placing the implant assembly adjacent the sacroiliac joint, inserting it into the joint space and expanding means are thereafter applied to expand the oppositely disposed side members into operative engagement with the joint.

Systems for and methods of fusing a sacroiliac joint

An orthopedic anchoring system for attaching a spinal stabilization system and concomitantly fusing a sacroiliac joint is disclosed that includes a delivery tool and an implant assembly for insertion into a joint space of a sacroiliac joint. The implant assembly may be secured using anchors inserted through bores within the implant body and into the underlying sacrum and/or ilium. The implant body may also include an attachment fitting reversibly attached to a guide to provide attachment fittings for elements of the spinal stabilization system. The implant assembly may be releasably coupled to an implant arm of the delivery tool such that the implant arm is substantially aligned with the insertion element of the implant assembly. An anchor arm used to insert the anchor may be coupled to the implant arm in a fixed and nonadjustable arrangement such that the anchor is generally aligned with a bore within the implant assembly.

Systems and methods for fusing a sacroiliac joint and anchoring an orthopedic appliance

Implants for the fusion or fixation of two bone segments are described. For example, the implants can be used for the fusion or fixation of the sacroiliac joint. The implants can include fenestrations, have a rectilinear overall cross-sectional area, and have a curvature. Some implants can also be used to rescue failed implants.

Implants for bone fixation or fusion

Systems for and methods of fusing a sacroiliac joint are provided which may include an implant adapted to be inserted into the joint space defined by the bones of a sacrum and an ilium and a delivery tool for inserting the implant into the sacroiliac joint. The method may include delivering the implant into the SI joint in a first position and transitioning the implant from the first position to a second position in situ. The implant may be configured such that in the second position the implant generally mimics a shape of the joint space of the sacroiliac joint. The implant may further include an actuation mechanism configured to cause the implant to transition from the first position to the second position. The actuation mechanism may include a hydraulic, pneumatic, geared or screwed mechanical arrangement.

Methods of fusing a sacroiliac joint

A surgical preparation tool for preparing a sacroiliac joint for a surgical procedure comprising a trial tool assembly and a cutting tool configured to releasably and slidably couple with the trial tool assembly, wherein the trial tool assembly is configured to guide the cutting tool during distal-proximal translation such that as the cutting tool distally advances relative to an implant trial of the trial tool assembly, at least a portion of a cutting element of the cutting tool extends generally over and perpendicularly outward from a first top surface of a body of the implant trial.

Systems for and methods of preparing a sacroiliac joint for fusion

An improved method of fusing the sacroiliac joint and tools for accomplishing the same is disclosed. In one embodiment, the present invention is a method that uses an intra-articular joint fusion device for connecting the sacrum and ilium that includes creating a first incision in the patient's skin proximal to the patient's sacroiliac joint, inserting a surgical channel tool into the incision from the patient's posterior, creating a void in the sacroiliac joint, inserting a fusion implant into the void, the fusion implant having at least one fixation element for engagement with bone tissue in the articular surfaces of the sacrum and the ilium, and driving the fusion implant into the void such that the at least one fixation element engages with bone tissue in an articular surface of at least one of the sacrum and ilium, and the fusion implant fixes relative positions of the sacrum and ilium.
