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.

A sacroiliac joint implant system includes a primary implant configured to be received in a sacroiliac joint of a patient and a secondary implant configured to couple with the primary implant. The primary implant includes a body extending from a proximal end to a distal end and a plurality of threads extending from the body. The secondary implant includes a first anchor configured to anchor within a sacrum of the patient and a second anchor configured to anchor within an ilium of the patient.

The present invention relates generally to implants and tools for the fixation or fusion of joints or bone segments. These tools include tissue dilators and protectors. Other tools include broaches used to shape bores in bone. The tools can also include a system for removing an implant from bone. Implants can include assemblies of one or more implant structures that make possible the achievement of diverse interventions involving the fusion and/or stabilization of lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. Implants for fusing both sacroiliac joints of a patient include a long implant that extends across both sacroiliac joints.

Threaded sacro-iliac joint stabilization (e.g., fusion, fixation) implants and methods of implantation and manufacture. Some implants include a threaded distal region, an optionally threaded central region, and an optionally threaded proximal region. The distal, central, and proximal regions have lengths such that when the implant is laterally implanted across a SI joint, the distal region can be positioned in a sacrum, the central region can be positioned across an SI-joint, and the proximal region can be positioned in an ilium.

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.

A system for fixating a dysfunctional sacroiliac joint for SI joint fusion, the system including a sacroiliac joint implant, a sacroiliac joint screw or rod and a delivery tool configured for approaching a sacroiliac joint. The system may include an implant having a porous 3D matrix structure and may be manufactured by laser or electron beam additive manufacturing. The delivery tool may include a radiolucent material. The SI fusion system may further include custom sacroiliac joint implants, anchors, alignment tools or targeting arms manufactured for a particular patient. Pre-surgical imaging studies, including 3D rendering, and their interpretation may assist in planning desired trajectories, anchor dimensions and implant dimensions and may provide details specific to the manufacture of particular sacroiliac joint tools or implants and their implantation into the sacroiliac joint. The system may be configured for use with surgical robots and may include an integrated nerve monitoring and stimulation system.

A bone fusion system including a collection vessel, an abrading and harvesting device, tubing and a probe. The abrading and harvesting device includes a needle portion and a sharpened tip. The needle portion has a central bore extending therethrough. The needle portion has a distal end. The sharpened tip is attached to the distal end of the needle portion. The tubing is operably connecting the collection vessel and the abrading and harvesting device. The probe has a threaded portion and a tip portion at a distal end of the threaded portion. The threaded portion has a thread on an outer surface thereof. The tip portion is unsharpened and does not have a thread on an outer surface thereof. The probe is extendible through the central bore.

A surgical fastener combination for use in posterior surgeries requiring require fusion between the occiput and pelvis. Among other things, the surgical fastener combination includes first and second cutters.

Bone implants, including methods of use and assembly. The bone implants, which are optionally composite implants, generally include a distal anchoring region and a growth region that is proximal to the distal anchoring region. The distal anchoring region can have one or more distal surface features that adapt the distal anchoring region for anchoring into iliac bone. The growth region can have one or more growth features that adapt the growth region to facilitate at least one of bony on-growth, in-growth, or through-growth. The implants may be positioned along a posterior sacral alar-iliac (“SAI”) trajectory. The implants may be coupled to one or more bone stabilizing constructs, such as rod elements thereof.

Aspects of the present disclosure involve a method of diagnosing and treating a sacroiliac joint of a patient comprising: a) delivering a first member into the ilium via a first posterior approach; b) delivering a second member into the sacrum via a second posterior approach; and c) diagnosing an ailment of the sacroiliac joint by: manipulating the first member relative to the second member; or identifying joint movement via a sensor positioned in or near the sacroiliac joint.
