  • Publication number: 20140243908
    Abstract: Bone screws and bone plates are provided that offer the surgeon the ability to either assemble the screws to the plate, or the plate to the screws, depending on the surgeon's preference and the patient's circumstances. The bone screws and bone plates of the present invention include a combination of geometric configurations that allow the screws and plates to fit together from different assembly directions. Additionally, the bone screws and bone plates can include material resilience features to allow expansion/contraction during assembly to allow bidirectional attachment to one another.

  • Patent number: 8790348
    Abstract: A spinal fixation element fixation reduction system is provided herein. In general, the system can include a cap element with a bore having a central axis extending therethrough wherein the cap element is configured to releasably engage any type of surgical device (e.g., an access sleeve, a vertebral body rotator, etc.). Further, the system can include a driver configured to be slidably and removably positioned through the cap element. The system can also include an actuator configured to apply a force to the driver substantially along the central axis of the cap element thereby moving the driver in a distal direction so as to effect reduction of a spinal fixation element into a bone anchor. Additionally, a method of reducing a spinal fixation element into a bone anchor is also provided wherein the method can be performed as a minimally invasive surgical procedure or as an open procedure.

  • Patent number: 8715352
    Abstract: An artificial disc replacement implant is provided that includes an implantable body having a superior surface adapted to be positioned adjacent to an endplate of a superior vertebra, and an opposite inferior surface adapted to be positioned adjacent to an endplate of an adjacent inferior vertebrae. The implantable body includes at least one wall formed therein and extending between the superior and inferior surfaces. The wall(s) can be adapted such that, when the implantable body is disposed between the endplates of adjacent superior and inferior vertebrae, the wall(s) will buckle by moving laterally and shorting in height under a load applied thereto by movement of the adjacent vertebrae. The implantable body can also include at least one opening formed adjacent to the wall(s) and extending between the superior and inferior surfaces of the implantable body.

  • Patent number: 8702762
    Abstract: Methods and devices are provided for passively locking a bone screw within a bone plate. In particular, the methods and devices allow a bone screw to be locked within a thru-hole in a bone plate without requiring any additional locking steps. In an exemplary embodiment, an annular feature is provided in a thru-hole of a bone plate, or in a bushing that is disposed within a thru-hole of a bone plate, for engaging a bone screw. The annular feature can be configured such that it allows the bone screw to be inserted through the thru-hole at various insertion angles while still being effective to prevent back-out of the bone screw, thereby locking the screw to the plate.

  • Patent number: 8636742
    Abstract: Methods and devices are provided for reducing a spinal fixation element into a spinal implant element. In one exemplary embodiment, a spinal rod reduction device is provided for reducing a spinal fixation element into a spinal implant element. The spinal rod reduction device can include a fastener engaging member for engaging at least a portion a spinal implant element, a reduction member for engaging at least a portion of a spinal fixation element, and a handle assembly mated to the reduction member. The handle assembly can be designed in such a way that actuation of the handle assembly causes movement of the reduction member relative to the fastener engaging member and the movement of the reduction member reduces the spinal fixation element into the spinal implant element. Two different styles of spinal rod reduction devices are discussed in detail. Various techniques are also provided for reducing a spinal fixation element into a spinal implant element.

  • Patent number: 8617246
    Abstract: Bone implantable devices and methodologies permit careful application of biologically active substances and management of bone growth processes. The device includes a body defining a carrier receiving area for locating adjacent bone. Carrier material is located in the carrier receiving area. Substance is delivered onto carrier material through a port. A pathway delivers substance from the carrier receiving area to the bone surface. The body may be in the form of a spinal fusion cage, facet fusion screw, artificial joint, bone fixation plate, interbody graft, IM nail, hip stem, or other bone-to-bone appliances or bone-to-device appliances. In use, carrier is installed in the carrier receiving area of the device. The device is then implanted adjacent a bone. The substance is applied to the carrier for subsequent delivery to the bone. By doping carrier material after device implantation, inadvertent contact of the substance with non-target bone is more easily eliminated.

  • Patent number: 8556905
    Abstract: A dilator retractor and the dilators that are used for minimally invasive spinal surgery or other surgery are configured to accommodate the anatomical structure of the patient as by configuring the cross sectional area in an elliptical shape, or by forming a funnel configuration with the wider end at the proximate end. In some embodiments the distal end is contoured to also accommodate the anatomical structure of the patient so that a cylindrically shaped, funnel shaped, ovoid shaped dilator retractor can be sloped or tunneled to accommodate the bone structure of the patient or provide access for implants. The dilator retractor is made with different lengths to accommodate the depth of the cavity formed by the dilators.
