The invention 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. In yet another embodiment, an implantable facet joint device comprises a caudal cross-member adapted to extend mediolaterally relative to a spine of a patient and adapted to connect to a first vertebra, a first artificial caudal bearing member adapted for connection to the caudal cross-member, and adapted to engage a first cephalad facet joint element connected to a second vertebra, and a second artificial caudal bearing member adapted for connection to the caudal cross-member at a predetermined spacing from the first bearing member, the second bearing member being adapted to engage a second caudal facet joint element connected to the second vertebra.

A method for implanting an articulating intervertebral disc prosthesis into an intervertebral disc space comprises surgically accessing the intervertebral disc space through an opening on a first lateral side of the intervertebral disc space and inserting a first half of the articulating intervertebral disc prosthesis through the opening and into the intervertebral disc space. The method further comprises inserting a second half of the articulating intervertebral disc prosthesis through the opening on the first lateral side of the intervertebral disc space and positioning the first half of the articulating intervertebral disc prosthesis on a second lateral side of the intervertebral disc space. The method also comprises positioning the second half of the articulating intervertebral disc prosthesis on the first lateral side of the intervertebral disc space.

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.

The invention discloses methods and devices for repairing, replacing and/or augmenting natural facet joint surfaces and/or facet capsules. A facet joint restoration device of the invention for use in a restoring a facet joint surface comprises: a cephalad facet joint element comprising a flexible member adapted to engage a first vertebrae and an artificial cephalad joint; and a caudad facet joint element comprising a connector adapted for fixation to a second vertebrae and an artificial caudad joint adapted to engage the cephalad facet joint. In another embodiment, the invention discloses a facet joint replacement device for use in replacing all or a portion of a natural facet joint between a first vertebrae and a second vertebrae comprising: a first cephalad facet joint element having a fixation member adapted to engage a lamina or spinous process of the first vertebrae and a first caudad facet joint element, the first caudad facet joint element comprising a first caudad connector adapted to fixate to the second vertebral body and an artificial caudad facet surface adapted to engage with the cephalad facet joint element.

The present invention relates to a locking mechanism and method of locking the relative positions of a fixation device like a bone screw and of a stabilization device like a rod. The locking mechanism includes a seat, a washer and a cap. The seat includes a bottom portion configured to receive the fixation device such that a socket of the bottom portion engages part of the fixation device and prevents the fixation device from passing entirely therethrough. The seat further includes a side portion configured to receive the stabilization device, a washer and a cap. When the washer and cap are fully engaged with the seat, the fixation device may be locked independent of the stabilization device. The locking mechanism may also include a locking element for locking the stabilization device.

The invention relates to a technique for precisely locating a line containing a predetermined point within the surgical site using a series of levels and plumb lines and internal anatomical features of the surgical site, using this location to precisely position and temporarily affix a site preparation scaffold relative to the patient's anatomy so that site preparation instruments can be introduced into the site at precise locations governed by the scaffold geometry and patient anatomy. This precise positioning of the scaffold also provides a way for the surgeon to use patient anatomical features to reliably and precisely prepare the surgical site. Scaffolds having angling features further increase the precise preparation of the surgical site. This increased precision in site preparation increases the probability of a successful procedure, and decreases the likelihood that additional surgery may be needed.
