Abstract: An intervertebral implant includes a body adapted to be implanted into an intervertebral space of a patient, the body defining a fusion aperture, and at least one cartridge with each cartridge disposed in the body and at least partially extending into the fusion aperture. Each cartridge includes an impedance sensor configured to measure electrical resistance, a radio frequency (RF) transmit antenna configured to transmit a RF signal, and circuitry for recording data from the impedance sensor and transmit the recorded data to an external clinician computing device through the RF transmit antenna. Such collection and use of data can be used to provide improved orthopedic outcomes.

Abstract: A rebounding device for sports balls including a frame defining a frame opening, a net disposed within the frame opening, a cable extending around a perimeter of the net and a cable tensioning system configured to tension the cable around the perimeter of the net and thereby pull the net taut within the frame opening.

Abstract: A surgical wire is part of a system that includes a retractor blade defining one or more paths for the surgical wire to follow. The paths can be one or more openings, cannulations, paths, tubes, other structures, or combinations thereof. The surgical wire can be routed through the front, back, and/or middle of the retractor blade and into a vertebral body. The surgical wire can be routed through a shim in communication with the retractor blade and into a vertebral body Systems and methods are used to insert surgical wires into bone. Systems and methods are used for removing surgical wires from bone. Systems include those for gripping and pulling or pushing surgical wires. Systems include those that interact with a retractor (e.g., an arm, body, or blade thereof) to facilitate removal of the surgical wire.

Abstract: An example retraction system includes a first retraction assembly, the first retraction assembly including a first arm coupled to a rack, a second arm coupled to the rack, a first retractor blade coupled to the first arm and a second retractor blade coupled to the second arm. The retraction system also includes a second retraction assembly, the second retraction assembly including a carriage configured to engage a blade post having a blade coupled to a distal end and a handle coupled to a proximal end, the blade post adjustable relative to the carriage. The retraction system also includes a third retractor blade coupled to the blade post.
