International Classification:

A61F 2/44

US Classification:

623017110, 606061000

Abstract:

The invention discloses devices, methods and systems for implanting articulating devices on the human spine. In some embodiments, three or more vertebrae are movable interconnected with artificial joints. Some embodiments are particularly well suited for implanting in the lumbosacral area of the spine. Some embodiments employ hybrid systems combining translaminar fixation with pedicular fixation of the device components. Some embodiments combine facet joint replacement with disc replacement.

Abstract:

An adaptable spinal facet joint prosthesis, including a pedicle fixation element; a laminar fixation element; and a facet joint bearing surface having a location adaptable with respect at least one of the pedicle fixation element and the laminar fixation element. The invention also includes a method of implanting an adaptable spinal facet joint prosthesis including the steps of determining a desired position for a facet joint bearing surface; and attaching a prosthesis comprising a facet joint bearing surface to a pedicle portion of a vertebra and a lamina portion of a vertebra to place the facet joint bearing surface in the desired position. The invention also provides a facet joint prosthesis implant tool including a tool guide adapted to guide a vertebra cutting tool; and first and second fixation hole alignment elements extending from the saw guide. The invention also provides systems for treating spinal pathologies that include intervertebral discs in combination with spinal and facet joint prostheses.

A61F 5/00

US Classification:

606102, 606 87

Abstract:

The present invention provides tools and methods designed to aid in the placement of artificial facet joints at virtually all spinal levels. One aspect of the present invention is a measurement tool for installing an artificial cephalad facet joint, the tool including a trial marker having a portion configured to be placed in a hole; and a trial body comprising a bore therethrough for slidaby receiving a portion of the trial marker. In some embodiments, the trial body further comprises an arm extending generally radially outward from the bore and configured to contact an opposing spinal prosthesis component. The trial body may further comprise a lower portion configured to be placed in the hole. The trial marker and the trial body are configured to cooperate to indicate a relative positioning between them. This measurement tool assists in the selection and/or configuration of an artificial cephalad facet joint for implantation in a patient. Another aspect is a method of using a spinal prosthesis component selection tool comprising accessing a target anatomy, creating a hole within a portion of the target anatomy, inserting a marker rod of a component selection tool in the hole, slidably adjusting a trial stem body along the marker rod until the trial body contacts an opposing spinal prosthesis component, determining the relative position between the trial body and marker rod, and selecting a component for implantation into the target anatomy based on the determined relative position.

Abstract:

The disclosure discloses methods, devices, systems and kits for repairing, replacing and/or augmenting natural facet joint surfaces and/or facet capsules. An implantable facet joint device of one embodiment comprises a cephalad facet joint element and a caudal facet joint element. The cephalad facet joint element includes a member adapted to engage a first vertebra, and an artificial cephalad bearing member. The caudal facet joint element includes a connector adapted for fixation to a second vertebra at a fixation point and an artificial caudal bearing member adapted to engage the cephalad bearing member. The artificial caudal bearing member is adapted for a location lateral to the fixation point. In another embodiment, an implantable facet joint device comprises a cephalad crossbar adapted to extend mediolaterally relative to a spine of a patient, the crossbar having opposite first and second ends, a connector element adapted to connect the crossbar to a first vertebra, a first artificial cephalad bearing member adapted for connection to the first end of the crossbar and adapted to engage a first caudal facet joint element connected to a second vertebra, and a second artificial cephalad bearing member adapted for connection to the second end of the crossbar and adapted to engage a second caudal facet joint element connected to the second vertebra.
