Systems for performing a minimally invasive sacroiliac joint fusion. The system may be in the form of a disposable kit, with the components streamlined so that the procedure can be performed in a few minutes. The screw components are self-drilling and self-tapping. The system may deploy blades through the walls of the primary screw which cut away material as the primary screw is set, for denuding the sacroiliac joint. The primary screws are designed to bore through and internalize bone tissue in an autografting process. The implant system may include components for packing bone grafting material into the screw to supplement autograft bone tissue internalized in the primary screw during placement. At least one side screw is passed through a head of the primary screw to anchor the head and inhibit rotation (backing out) after implantation. The primary screw may include features that facilitate rotational alignment.

An intervertebral stabilization screw includes a main body with a distal bone-fixation thread. The distal thread is located at a distal end of the main body. A receiving area for a percutaneous drive tool is at a proximal end. The screw also has externally and separated from the distal thread a proximal bone fixation thread located at its proximal end.

The invention concerns an implantation assembly comprising a bone-anchoring element comprising a threaded rod provided at one of its ends with a head and an instrument for driving the bone-anchoring element, said instrument comprising a drive spindle removably premounted on the bone-anchoring element.

The present invention relates to an implant, to an instrument for implantation of the latter and to a method for manufacturing this implant which includes an elongated body (10) between a free end and a head (18) along a longitudinal axis on the one hand and turns (12) of at least one threading on at least one portion of said body (10) in proximity to the free end, along the longitudinal axis on the other hand, characterized in that the body (10) includes a longitudinal internal conduit (11) in at least one portion to along the longitudinal axis, obtained by at least one first central machining operation parallel to the longitudinal axis and at least one second machining operation in a so-called transverse plane, not parallel to the longitudinal axis and crossing the wall of the body (10) as far as the longitudinal internal conduit (11) by making windows (15) communicating between said longitudinal internal conduit (11) and the outside of the body (10).

A surgical system includes a sleeve defining a passageway. An adapter is removably coupled to the sleeve. The adapter defines a channel. A delivery device includes a distal end positioned in a channel of the adapter. A bone fastener includes a head and a shank defining a cannula. A distal portion of the adapter is positioned in the shank such that the channel is in communication with a cannula of the shank. A plunger is movably disposed in a lumen of the delivery device. The plunger is configured to move a material through the lumen and the channel and into the cannula. Methods and kits are disclosed.

An expandable support device for tissue repair is disclosed. The device can be used to repair hard or soft tissue, such as bone. The expandable support device can have interconnected struts. A method of repairing tissue is also disclosed. The expandable support device can be inserted into a damaged bone and radial expanded. The radial expansion of the expandable support device struts can cause the struts to cut mechanically support and/or the bone.

Attachment devices and methods of using the same are disclosed. The attachment devices can be fenestrated. The fenestrations can control the flow of fluid out of and/or into the device.

The risk of bone cement extravasation can be reduced by delivering a calcium-dependent polymerizing sealant into a bone structure prior to delivery of bone cement into that structure. The polymerization of the sealant in response to the calcium within the bone structure can fill cracks and any other potential cement leakage paths, thereby minimizing the potential for subsequent extravasation. The benefits of the use of a calcium-dependent polymerizing sealant can be provided in any procedure involving the use of bone cement, such as spinal fixation, vertebroplasty, and kyphoplasty, among others.

A bone graft delivery system includes a rasp having an elongate body extending between a proximal end and a distal end, a lumen extending through the elongate body and configured to receive bone graft material, a rasping surface removably couplable to the distal end of the elongate body and configured to decorticate bone material of a patient, and one or more openings configured to deliver bone graft material from the lumen.

Various bone cement guides are disclosed that may connect directly to a fenestrated bone screw or connect to a spinal construct that is coupled to a fenestrated bone screw. In various embodiments, cement guides may include a three-part assembly including a hollow outer sleeve and a hollow inner sleeve with a removable inner rod. In various embodiments, the hollow inner sleeve may be movable between a retracted position and an extended position and in the extended position a distal end of the inner sleeve may splay outward and capture the head portion of a fenestrated bone screw. In other embodiments, a distal end of the outer sleeve may surround and capture tabs of an extended tulip head connector while the inner sleeve couples to an inside surface of the extended tulip head connector.
