Abstract: An intervertebral scaffolding system is provided having a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state, the laterovertically-expanding frame having a stabilizer, one or more tensioners, or a combination of the stabilizer with one or more tensioners. The stabilizer slidably engages with the distal region of the laterovertically-expanding frame and both the stabilizer and the one or more tensioners are configured for retaining the laterovertically-expanding frame from a lateral movement that exceeds the expanded state. The expanded state, for example, can be configured to have an open graft distribution window that at least substantially closes upon the reversible collapse.

Abstract: A surgical fixation assembly and related method of fusing a sacroiliac joint are described herein. The surgical fixation assembly includes a compression member, a stabilizer, and a locking element. The compression member is rotatably implantable into two bone segments separated by a joint. The stabilizer is configured for coupling with the compression member in situ after implantation of the compression member and prevents rotation of the compression member after implantation. The locking element is provided on the stabilizer and is moveable from a first position that allows coupling of the stabilizer and compression member to a second position that prevents uncoupling of the stabilizer from the compression member.

Abstract: 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.

Abstract: A surgical guidance device is cannulated for passage of a guidewire or pin and includes a hand grip and differential control assembly for driving the guidewire or pin and differentially driving a screw, such as but not limited to a pedicle screw, into bone. The differential control assembly resides in a housing and includes a differential control assembly for gripping and locking or releasing the guidewire or pin and effecting directional movement (relative to the user holding the surgical guidance device) either distally into the bone or proximally away from bone to thereby drive or retract the guidewire. The differential control assembly also allows distal or proximal drive of a screw, such that one or both the guidewire and screw can be passed proximally or distally alone or together.

Abstract: A bipolar dissector includes a handle actuatable by squeezing, a housing extending from and coupled to a distal end of the handle, and a shaft coupled to a proximal end of the handle and extending past the distal end of the handle and through the housing to a distal end of the housing. The shaft includes first and second electrical lines extending from a proximal end to a distal end of the shaft and an insulating material electrically insulating the electrical lines from each other and from the handle and the housing. The bipolar dissector also includes a pair of forceps including a first tine and a second tine. The tines extend from the electrical lines at the distal end of the shaft at the distal end of the housing. Squeezing the handle actuates the forceps in the same direction as the squeezing.

Abstract: An adapter mounts a tracking target to an end fitting of an existing r instrument. The adapter includes A shaft having an engagement fitting at one end thereof that is configured the same as the end fitting of the existing instrument so that a handle can be mounted on the adapter instead of on the end fitting of the tool/instrument. The adapter shaft includes a collet that cooperates with a locking nut to clamp the collet onto the instrument shaft when the end fitting of the instrument is disposed within the collet. A tracking element is provided that is detectable by a tracking system to determine the position and orientation of the instrument. The tracking element includes a mounting feature that is configured to snap onto the adapter shaft at a known axial position thereon while permitting rotation of the tracking element about the longitudinal axis of the adapter shaft.

Abstract: A coaxial dual component locking screw includes a screw component and a housing component. The screw component includes a thread extending at least a portion of the length from the tip to the head and the housing component includes each having a plurality of wherein the slits of the housing component are adapted to correspond to a pitch of the thread of the screw component. When the screw component and the housing component are engaged, the thread of the screw component protrudes through the slits and provides resistance to migration and pull out of the coaxial dual component locking screw when implemented in a bone.

Abstract: An intervertebral scaffolding system is provided having an expandable frame operable for a reversible collapse from an expanded state into a collapsed state, the expandable frame having a stabilizer, one or more tensioners, or a combination of the stabilizer with one or more tensioners. The stabilizer slidably engages with the distal region of the expandable frame and both the stabilizer and the one or more tensioners are configured for retaining the expandable frame from a lateral movement that exceeds the expanded state, and the stabilizer can include a locking element that engages with the expansion member to lock the expansion member to the stabilizer when the expansion member is fully inserted into the frame. The expanded state, for example, can be configured to have an open graft distribution window that at least substantially closes upon the reversible collapse.
