Implants for the fusion or fixation of two bone segments are described. For example, the implants can be used for the fusion or fixation of the sacroiliac joint. The implants can have a matrix structure, have a rectilinear cross-sectional area, and have a curvature.

This disclosure relates to a graft preparation station and methods for repairing bone defects. The station described herein may be utilized for dimensioning a graft prior to positioning the shaped graft at a surgical site.

An apparatus and methods are provided for a trephine bone graft harvester for extracting morselized bone from patients. The trephine bone graft harvester includes a bone cutter affixed to an outer hub. The bone cutter comprises a hollow tube having cylindrical wall and a distal cutting edge. A bone graft collector is sheathed within the bone cutter. The bone graft collector includes a distal scoop adjacent to the distal cutting edge of the bone cutter. The distal scoop is configured to move morselized bone away from the distal cutting edge. An inner hub is affixed to the bone graft collector and coupled with the outer hub. The inner hub includes a proximal shank configured to be engaged with a rotary tool suitable for applying torque to the inner hub.

Devices, systems, and methods for performing a transcorporeal microdecompression are described. The transcorporeal microdecompression may include a bone void plug allograft and specialized instruments for performing the procedure. This procedure may be performed under navigation and/or with robotic assistance.

Arthrodesis surgical methods and apparatus. After a guide pin is inserted into the joint to be fused, a core saw creates a cored-out cavity in the joint to be fixated. An autograft bone core is harvested with a core saw and is inserted into the cored-out cavity. The joint is then immobilized for the healing process.

The present application is generally directed to implantable systems, devices and related methods pertaining to spinal surgery. In particular, the present application discloses a frame and spacer system for inserting into a disc space. The frame and spacer system is of low profile. The frame can receive different fixation devices, including threaded and non-threaded fixation devices.

Techniques are described for bone-graft harvesting in orthopedic surgery. Processing circuitry may obtain a virtual model of a bone graft to be harvested from a donor bone, wherein the virtual model of the bone graft specifies a volume of the donor bone to be harvested as the bone graft; and output for display, via a visualization device, a graphical representation of the specified volume to be harvested relative to a portion of the donor bone viewable via the visualization device.

A cylindrical plug to close a femoral opening drilled in a femur to receive an intramedullary cutting guide, to prevent bleeding from the opening after removal of the intramedullary cutting guide from the opening.

A device(100) and method(4100) for autologous bone graft harvesting simultaneously cuts a cross-section of a bone(900) longitudinally with a longitudinal drill assembly(102), and transversely with a saw assembly(126) during a bone(900) drilling to obtain a bone block for repairing and rebuilding diseased bones. The longitudinal drill assembly(102) and the saw assembly(126) simultaneously cut a cross-section of a bone(900). The device(100) is hand-controllable, drill motor powered, and spring-tensioned to selectively cut internally to the captured bone for internal bone harvesting. The longitudinal drill assembly(102) includes a drill shaft(114) extending perpendicular from a drill plate(112), having a flat surface(204) with a depth gauge(116). A module assembly(118) includes a module plate(120) disposed above the drill plate(112). Pins(302a,302b) extend from the upper face(308a) of the module plate(120) to engage ends of slots(400a,400b) to restrict over-rotation of saw plate(128). The saws (136a,136b) move between an open position(700a) for stowage, and a closed position(700b) while sawing the bone(900).
