Devices, systems, and methods for bone stabilization, especially ulna head stabilization. The stabilization system may include a bone plate having an elongated portion extending along a longitudinal axis between a proximal end and a distal end. The bone plate defines a plurality of through holes extending through the elongated portion. A plurality of fasteners are configured to extend through one or more of the plurality of through holes in the bone plate and configured to secure the bone plate to the bone. The proximal end of the elongate portion has an arcuate configuration.

A microfracture impactor tool including a housing defining a central axis, the housing can include a proximal portion and an opposite distal portion. A handle can be connected to the distal portion of the housing and can extend outward therefrom. The impactor tool can include a grip that is pivotably connected to the proximal portion of the body near the handle. The impactor tool can include an impactor wire configured to impact bone, and a guide tube connected to the distal portion of the housing that is configured to retain the impactor wire.

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 an open tip having a cutting edge configured to cut bone tissue in the SI Joint.

An instrument set for installing a fusion implant into the sacroiliac joint (“SI Joint”). The apparatus comprises a working channel having an alignment means, a joint locator having a first keying means, an abrading device having a second keying means, and an implant inserter having a third keying means. The first, second, and third, keying means mate with the alignment means when the joint locator, abrading device, and implant inserter, respectively, are inserted into the working channel.

A method for forming and abrading an implant void in a sacroiliac joint (“SI Joint”) without the use of a rotary cutting instrument. The method incorporates a multimodal abrading device having abrading surfaces on opposing sides and an open tip comprising a cutting edge. The method includes the step of using the abrading head to cut bone tissue from the SI Joint at an insertion point while simultaneously using the abrading surfaces to decorticate the cortical bone at the insertion point.

A self-drilling bone fusion screw apparatus is disclosed which includes at least first and second sliding boxes. A first screw member having a tapered end and a threaded body is disposed within the first sliding box, and a second screw member having a tapered end and a threaded body disposed within the second sliding box. An adjuster adjusts the height of the sliding boxes. The screw members are screwed into vertebral bodies in order to fuse the vertebral bodies together. A plurality of the self-drilling bone fusion screw apparatuses may be attached together and/or integrated via a plate or cage. Also disclosed is a cervical facet staple that includes a curved staple base and at least two prongs attached to the bottom surface of the curved staple base.

A microfracture device for creating small holes in a bone. The microfracture device includes a handle having a body extending along a central longitudinal axis with a proximal end and a distal end; a shaft connected to the distal end of the body, the shaft having a distal tip; wherein the distal tip extends at first angle relative to the central longitudinal axis; a sliding mechanism slidably engaged with a surface of the body and moveable between a first configuration and a second configuration; and wherein the sliding mechanism further comprises a striking surface extending therefrom, wherein the striking surface is positioned at a second angle to the central longitudinal axis that is at least substantially similar to the first angle.

A fixing device for a tibia alignment system for knee operations includes a transverse bar, the front end of which can be connected to a main rod of the tibia alignment system. The main rod is configured for an alignment along the tibia. A rear end of the transverse bar has an anchor system with at least one anchor pin that extends obliquely to the transverse bar and can be driven into a knee joint-side end of the tibia. The anchor system has a drive-in anvil into which the anchor pin is integrated and which is designed to transmit impact forces acting on the drive-in anvil from the outside to the anchor pin in order to drive the anchor pin into the tibia. The anchor pin and drive-in anvil are guided in the transverse bar in a longitudinally movable manner.

A microfracture device for creating small holes in a bone. The microfracture device includes a handle having a body extending along a central longitudinal axis with a proximal end and a distal end; a shaft connected to the distal end of the body, the shaft having a distal tip; wherein the distal tip extends at first angle relative to the central longitudinal axis; a sliding mechanism slidably engaged with a surface of the body and moveable between a first configuration and a second configuration; and wherein the sliding mechanism further comprises a striking surface extending therefrom, wherein the striking surface is positioned at a second angle to the central longitudinal axis that is at least substantially similar to the first angle.

A drill-less method of stabilizing a sacroiliac joint using a multimodal abrading device to create a rich environment for bony fusion. The unique decortication instrument includes an integral slap hammer assembly joined with a rasp-box osteotome tooling head to simultaneously remove cartilage from the joint while preparing the sacrum and ilium down to bleeding bone. Subsequent to joint preparation, an implant with a large bone graft window may be implanted into the prepared SI joint through a specially designed access cannula.
