  • Patent number: 9872712
    Abstract: A sacro-iliac implant includes a body extending from a first portion having an outer surface configured for fixation with a sacrum to a second portion having an outer surface being spaced apart and non-continuous with the outer surface of the first portion. A sleeve is disposed about the body and configured for implantation within at least an ilium. The sleeve extends from a first portion to a second portion having an inner surface and a flange disposed to engage an outer non-articular surface of the ilium. The inner surface of the second portion of the sleeve is engageable with the outer surface of the second portion of the body to cause axial translation of the body relative to the sleeve such that naturally separated articular surfaces of the sacrum and ilium are drawn into fixation to immobilize the SI joint. Methods of use are disclosed.

  • Patent number: 9101400
    Abstract: A flexible connection unit for use in a spinal fixation device is provided. The flexible connection unit includes an elongated member, such as a vertebral rod, having a first end portion and a second end portion opposite each other with a transition portion extending therebetween. The first end portion of the vertebral rod comprises an oval shape and the second end portion contains an oval or non-oval shape. The major diameter of the oval shaped first end is parallel to the sagittal plane of a patient's body and provides the higher stiffness for fusion to resist flexion in the sagittal plane. The second end portion of the vertebral rod is perpendicular to the sagittal end of a patient's body and provides the lower stiffness for fusion.

  • Patent number: 9072546
    Abstract: A spinal construct for implantation in a patient to provide stabilization to spinal structure with improved load sharing includes a flexible spinal rod having a first end and a second end, the spinal rod being configured to provide stabilization to spinal structure. It also includes a first bone fastener configured to securely attach to the flexible spinal rod and a second bone fastener configured to securely attach to the flexible spinal rod. The second bone fastener is a dynamic fastener arranged to provide motion in one direction more than another direction. The flexible spinal rod and the second bone fastener are oriented to cooperate in a manner that achieves load sharing by dynamically flexing under applied loads in a manner that distributes stresses and strains between the flexible spinal rod and the second bone fastener.
