  • Patent number: 10543102
    Abstract: The present invention is directed to a low profile intervertebral implant for implantation in an intervertebral disc space in-between adjacent vertebral bodies. The intervertebral implant includes a plate preferably coupled to a spacer. The plate is preferably formed from a first material and the spacer is preferably formed from a second material, the first material being different from the second material. The plate is preferably sized and configured so that the plate does not extend beyond the perimeter of the spacer. In this manner, the plate preferably does not increase the height profile of the spacer and the plate may be implanted within the intervertebral disc space in conjunction with the spacer.

  • Patent number: 10500067
    Abstract: A method is used for aligning an acetabular cup insertion instrument by taking a single lateral view pre-operative digital x-ray of a standing patient's pelvis. The natural pelvic tilt angle is determined by locating an anterior pelvic plane (APP) which is defined by first, second and third points on the anterior of the pelvis and determining the angle between the APP and a coronal plane perpendicular to the surface on which the patient is standing. The patient is then placed on a surface of an operating room table in a supine position. A position tracking device is placed on the patient's pelvis to track movement. Thereafter an operating room navigation or orientation system is used to relocate the APP defined by the first, second and third points. A cup insertion instrument having a position tracking device thereon is oriented using the navigation or orientation system.

  • Patent number: 10426565
    Abstract: Knee arthroplasty instrument systems directly reference and align with the anterior distal with the anterior distal femoral cortex, the mechanical axis of the leg, and Whiteside's line. The anterior femoral resection is aligned in the same plane as the anterior distal femoral cortex. The center of the femoral head, the medial/lateral center of the distal femur, the medial/lateral center of the proximal tibia, and the second toe, medial/lateral center of the ankle, or anterior tibial spine are all aligned to the mechanical axis of the leg while the leg is in full extension and the knee joint is distracted. Whiteside's line is referenced while the distal femur is intact, before any distal femoral resection, and the anterior and posterior femoral resections and chamfer cuts are aligned to this reference using a jig. Methods of using the instrument systems are disclosed.

  • Patent number: 10398477
    Abstract: A Static Compression Device (SC device) for active, measurable compression of a spinal fusion graft is disclosed. The device attaches to adjacent vertebral bodies or other bone pieces works with a compression tool to apply compressive force to adjacent vertebral bodies or pieces of bone to assist fusion. Once compressed, the SC device locks to maintain the compression applied at surgery, while preventing further compression after surgery. In one embodiment, the compression device applies a desired, quantified, amount of force to allow the surgeon more control over the force applied to a cervical, thoracic or lumbar implant than previously available. The SC device may be used to compresses multiple adjacent vertebrae across adjacent bone graft(s) to facilitate fusion of these vertebrae to treat pain from damaged disks between vertebrae that impinge on the spinal cord and nerve roots. SC device may also apply compression across fractures to facilitate union.

  • Patent number: 10363143
    Abstract: A cage or spacer device for harvesting bone graft material for use in bone fusion surgery, e.g., spinal fusion. The device is inserted between facing surfaces of the bones to be fused, and a chamber is formed in the device for containing a slurry of morselized bone and blood to be effused from the bones. In one embodiment, a bone cutter assembly including a cannula having a bend at a distal end is inserted in the chamber for operation. A wire having a cutting tip is passed inside the cannula so that the tip projects a determined distance from the distal end of the cannula. Accordingly, the cutting tip strikes and cuts grooves in the facing surfaces of the bones when the cannula is rotationally driven about its axis. The mentioned slurry effuses from the grooved surfaces and remains in the chamber to promote a solid and healthy fusion.
