Methods of stabilizing the sacroiliac joint by placing an expandable device in the joint to generate laterally opposing forces against the iliac and sacral surfaces of the SI joint to securely seat the device in a plane generally parallel to the SI joint. The expandable device is coated with or otherwise contains a bone material to promote fusion of the joint. The expandable device used in methods of the present invention can be, for example, an expandable cage, a balloon, a balloon-expandable stent or a self-expanding stent.

A sacro-iliac implant delivery instrument includes a first arm connected to a first cannula. The first cannula is rotatable relative to the first arm and is configured for support of a fastening element. A second arm is connected to the first arm. The second arm is rotatable relative to the first arm and is configured for detachable connection to a sacro-iliac implant. The second arm and the first cannula are configured for rotation relative to the first arm to a preset orientation such that the second arm is disposed along a first predetermined trajectory for delivering the sacro-iliac implant and the first cannula is disposed along a second predetermined trajectory for delivering the fastening element in alignment with the sacro-iliac implant for transarticular fixation. Methods of use are disclosed.

A sacro-iliac implant includes at least one wedge-shaped body. The body defines an outer surface configured to engage at least one articular surface of a sacro-iliac joint. Systems and methods employing the sacro-iliac implant are disclosed.

A system for preparing the sacroiliac (SI) joint for an SI joint fusion, and optionally delivering an implant to the SI joint, is described herein. The implant is inserted via an inferior inlet approach. A sliding joint finder is inserted into the joint, followed by insertion of a working cannula. The working cannula is operatively coupled to the sliding joint finder, in that it is configured to fit over the sliding joint finder, allowing subsequent removal of the sliding joint finder, and providing a hollow cavity for joint fusion preparation, decortication and insertion of an implant. This system and method provides a less invasive and safer approach for fixing an SI joint or delivering an implant to the SI joint than currently available methods.

Embodiments of the present invention relate generally to implant placement into bone. More specifically, embodiments of the invention relate to implant placement across the sacro-iliac joint. Placement can be facilitated using various CT imaging views that allow the implants to be placed in bone associated with articular cartilage.

Methods of implanting SI joint stabilization implants across a SI joint from a dorsal approach. The methods may include advancing an elongate implant positioning guide in a dorsal trajectory into an ilium of a subject, directly engaging a guide interface member of a SI joint stabilization implant with the positioning guide to restrict movement of the implant with respect to the positioning guide in at least one direction, and advancing the implant across the SI joint while guiding the implant with the positioning guide.

A sacroiliac joint implant is formed from a web structure having a space truss with two or more planar truss units having a plurality of struts joined at nodes. The web structure is configured for fusion of a sacroiliac joint.

Methods are described for conducting minimally invasive medical interventions utilizing instruments and assemblies thereof to stabilize and/or fixate a dysfunctional sacroiliac (SI) joint. In one embodiment, a defect creation assembly is advanced from a posterior approach into the SI joint and configured to create pilot SI joint opening; portions of which being disposed in the sacrum and ilium bone structures. After the pilot SI joint opening is created, a prosthesis is press-fit into the pilot SI joint opening, wherein the pilot SI joint opening transitions to a larger post-prosthesis insertion SI joint opening and the prosthesis is securely engaged to the sacrum and ilium bone structures.

Systems are described for conducting minimally invasive medical interventions utilizing instruments and assemblies thereof to stabilize and/or fixate a dysfunctional sacroiliac (SI) joint. The systems include a drill guide adapted to create a pilot SI joint opening in the dysfunctional SI joint through an incision comprising a length no greater than 3.0 cm; portions of the pilot SI joint opening being disposed in the sacrum and ilium bone structures. The drill guide includes a tri-mode fixation system adapted to position and stabilize the drill guide during creation of the pilot SI joint opening in the dysfunctional SI joint and delivery of the SI joint prosthesis therein. The systems also include a SI joint prosthesis configured to be inserted into the pilot SI joint opening of the dysfunctional SI joint, and a prosthesis deployment assembly configured to engage the SI joint prosthesis and advance the SI joint prosthesis into the dysfunctional SI joint.

A Diastasis Recti Splinting Garment is described which includes a plurality of attached torso straps and pelvic straps which the user wraps around their body and connects to the garment so as to approximate the 2 sides of the abdominal wall, providing support to the linea alba and fascial sheathes to allow for tissue healing. Furthermore, the adjustable angled straps encircle the torso and pelvis of the user to restore the integrity of the core, providing stability to the ribcage, spine and pelvis. Restoring the integrity of the core lends itself to optimal activation of the deep core stabilizers, including the abdominal muscles as well as the musculature of the pelvic floor, back, and diaphragm. This in turn aids in dynamic stability of the spine, ribcage and pelvis. This allows maximum support of the diastasis recti, consequently facilitating tissue healing through balancing intra-abdominal pressure, while still supplying support to the vulnerable pelvic floor and stability to the spine, ribcage and sacroiliac joints.

Methods are described for conducting minimally invasive medical interventions utilizing instruments and assemblies thereof to stabilize and/or fixate a dysfunctional sacroiliac (SI) joint. The methods include the initial steps of providing a drill guide assembly adapted to create a pilot opening in the dysfunctional SI joint, a prosthesis configured to be inserted into the pilot opening created by the drill guide assembly and a prosthesis deployment assembly adapted to engage and advance the prosthesis into the pilot opening in the dysfunctional SI joint. The drill guide assembly includes a drill guide having a prosthesis access opening therethrough; the opening having a configuration that corresponds to the shape of the prosthesis. In some aspects of the invention, the methods thus include the step of advancing the prosthesis through the drill guide and then into the pilot opening in the dysfunctional SI joint with the prosthesis deployment assembly; the initial advancement of the prosthesis through the drill guide providing consistent, optimal placement of the prosthesis in the dysfunctional SI joint.
