    Abstract: A low-profile offset-type spinal fusion device includes a first screw, a connection base, a nut and a compression part. The first screw has an external thread and a flange. The connection base includes a penetration part and a connection part disposed no higher than the penetration part, and can sleeve the first screw through a first hole of the penetration part to contact the flange with opposite ends of the first screw protruding out of the first hole. The nut, used to engage the first screw, has a bottom surface to contact against the penetration part. When the first screw is installed by penetrating the first hole, the nut and the flange are located to opposite ends of the first hole. The compression part is to screw into a cavity of the connection part for depressing a connecting bar tightly in the cavity.

  • Patent number: 11559680
    Abstract: This invention relates to devices and methods for the electrochemical removal of unwanted deposits in humans and animals, or for prevention of bone loss following implantation of metal and other surgical materials in the body. A selected voltage is applied using direct current and an electrode to discourage growth or remove deposits, including bone spurs, and may be applied using microneedles in skin contact with a human or animal.

  • Patent number: 11504165
    Abstract: An ultrasonically assisted clamping system and method for extending a spinal support rod system to additional vertebrae of the spine. A clamp assembly and a receptacle assembly securely couple an additional extension rod to an existing spinal support rod. Various embodiments further include an ultrasonic assist for cutting through tissue that may be present in the vicinity of the existing spinal support rods. In some embodiments, the clamp assembly is configured to augment the ultrasonic aspect of the system. The system cuts through and locally removes tissue from and proximate to the spinal support rods where the clamp assembly is to be mounted, without the need for a separate surgical procedure for removing the tissue prior to implantation, thereby providing a secure clamping of the newly implanted extension rod to the existing base spinal support rod.

  • Patent number: 11504170
    Abstract: A bone fixation assembly may include an elongate fixation member and a flexible tensioning element. The elongate fixation member may include a central longitudinal axis, a distal portion couplable to a first bone fragment of a bone, and a proximal portion couplable to a second bone fragment of the bone to provide fixation of the second bone fragment relative to the first bone fragment. The flexible tensioning element may be couplable to the proximal and distal portions of the elongate fixation member to secure the elongate fixation member to the bone. The flexible tensioning element may be configured to span a bone fracture intermediate the first bone fragment and the second bone fragment to preload the bone fracture in compression to resist tensile force imparted across the bone fracture, thereby maintaining fixation of the first bone fragment relative to the second bone fragment.

  • Patent number: 11484348
    Abstract: A bone fixation assembly includes a plurality of bone fixation elements that each include a bone anchor configured to be implanted into underlying bone, such as a vertebra. Each bone anchor is received in an anchor seat, and the anchor seats are joined by a fixation rod so as to operatively couple and fix the position and orientation of the vertebrae relative to each other. The bone anchor is free to rotate relative to the anchor seat, and is also free to pivot in a desired direction relative to the anchor seat.

  • Patent number: 11389207
    Abstract: A spinal screw assembly includes a bone screw having a head with a rounded outer surface and an anchor portion for fixation to the bone. The assembly also includes a body member defining an internal cavity communicating with a bottom surface of the body member through a lower opening, with an interior surface adjacent the lower opening configured to engage the rounded outer surface of the head of the screw, and an upper portion defining a channel for receiving a fixation rod. The screw head is configured for uploading into the cavity of the body member through the bottom opening until the rounded outer surface enters into pivotal engagement with the interior surface of the internal cavity, with the screw extending downwardly through the lower opening, so as to allow for variable angular movement of the bone screw relative to the body member prior to locking the spinal screw assembly with a closure.
