A bone screw implant comprising a bone screw and a sleeve. The bone screw includes a first end, a second end opposite the first end, a cannula extending from the first end to the second end, an externally treaded portion provided between the first end and the second end, and at least one cutting flute. The at least one cutting flute extending from the first end toward the second end, where the cutting flute comprises at least one window extending through the cutting flute and in communication with the cannula. The sleeve comprising a cylindrical body portion extending about the second end of the bone screw, and a plurality of projections extending from the cylindrical body portion configured to engage bone as the bone screw is threadingly advanced.

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.

A fixation implant includes a head, a shank and a distal tip, and one or more of the head, shank and distal tip may be cannulated. The shank includes a threaded ingrowth portion extending from the head to the tapered distal tip that includes external threads, and at least one open network body extending along the length of the ingrowth portion. The open network body selected from one or a combination of a helix, an arrangement of trusses, a scaffold of open and interconnected pores, a porous framework of random open and interconnected pores, and combinations of these.

An implantable device for sacroiliac (“SI”) joint fusion and an associated method employ an SI joint fusion portion and an anchor portion of smaller diameter than the SI joint fusion portion and that extends distally from a distal end of the SI joint fusion portion. The SI joint fusion portion is externally threaded and is configured to, when surgically implanted, extend across the SI joint. The anchor portion in turn extends distally from the SI joint fusion portion and is configured for implanting entirely within the patient’s ilium adjacent the SI joint. In certain configurations, the joint fusion portion is configured to enable fixation of spinal equipment at a proximal end of the joint fusion portion.

Various embodiments of a coupler and an intradiscal implant for alignment and fusion of the sacroiliac joint are described herein.

Sacro-iliac joint stabilizing implants adapted for implanting across a SI joint from a dorsal approach. Methods of, and delivery tools adapted for implanting sacro-iliac joint stabilizing implants across a SI joint from a dorsal approach.

An instrument set for installing a fusion implant into the sacroiliac joint. The apparatus comprises a working channel having an alignment means, an implant inserter having an inserter keying means for mating with the alignment means when the implant inserter is inserted into the working channel. The implant inserter has an insertion end with a pair of tines for releasably receiving a joint fusion implant.

A decorticating device for preparing a sacroiliac joint (“SI Joint”) to receive a graft implant. The decorticating device comprises an abrading head having abrading surfaces on a first pair of opposing sides, the abrading surfaces configured for decorticating the cortical bone of the SI Joint. The abrading head further comprises a second pair of opposing sides, each side of the second pair of opposing sides comprising a curved distal portion having a curved cutting edge.

A method of treating a sacroiliac joint and/or a region proximate the sacroiliac joint includes distracting and/or stabilizing a recess between a sacral wall of a sacrum and an ilial wall of an ilium, cutting a surface of the ilial wall using a cutting device, and positioning an implant having a first planar wall and a second planar wall opposite the first planar wall into the recess, such that the first planar wall of the implant is in contact with an uncut surface of the sacral wall, and the second planar wall is in contact with the cut surface of the ilial wall. The implant can be formed as a wedge-shape, a double-wedge shape, or a cuboid shape.

A method for treatment of a sacral insufficiency fracture comprises a plurality of steps. A step is performed for placing an access device within a patient. Such placing of the access device includes causing a distal end portion of the access device to traverse through a sacroiliac joint of the patient and to traverse into the patient's sacrum until the distal end portion of the access device is within a region of the sacrum where a sacral insufficiency fracture is located. Thereafter, a step is performed for delivering bonding material though a portion of the access device into the sacrum at the region thereof where the sacral insufficiency fracture is located.
