An apparatus for surgical fusion of a cranio-cervical junction includes a plate member, where the plate member includes a bottom portion configured to be secured to a cranium; a top portion including a plurality of perforations extending therethrough configured to promote bone growth, wherein the top portion and the bottom portion define a graft accommodation space; and first and second side portions coupled to the top and bottom portions on first and second sides of the graft accommodation space. The first side portion is configured to receive a first support rod and the second side portion is configured to receive a second support rod.

The present invention is a method and device for the correction and reduction of bone deformities, such as metatarsus primus adductus, using a plate body with winged buttresses and dorsal loop. The method and device can be affixed to a bone without any drilling or violating of the bone and can use a tethering technique which does not require drilling into the second metatarsal, nor does it require the placement of a prominent suture knot/button device medially along the first metatarsal.

A bone plate includes first and second longitudinal sides, a plurality of through holes longitudinally displaced in the bone plate between the first and second longitudinal sides, and a plurality of tubular guide elements coupled relative to the plurality of through holes. Plate bending tools are provided. Each includes a handle having a first end, a second end, and a longitudinal axis, and an end effector coupled to the first end of the handle. The end effector includes a retaining arm that is provided with a bore having a bore axis extending transverse relative to the longitudinal axis and a fulcrum. The bore is sized to received a portion of a tubular guide element coupled to the bone plate such that the retaining arm can stably engage the tubular guide element. The fulcrum is adapted to bear against one of longitudinal sides of the bone plate.

A prosthesis replaces all or a portion of a natural facet joint on a vertebral body. The prosthesis has a prosthesis body accommodating fixation to the vertebral body at or near a pedicle and without support by a lamina. The prosthesis body has a fastening element installed within the vertebral body at or near a pedicle. The prosthesis further has an artificial facet joint structure carried by the prosthesis body at a location spaced from the fastening element. The artificial facet joint structure is adapted and configured to replace all or a portion of a natural facet joint.

The present disclosure is directed to a system for guided growth where the implanted physeal tether device can be unlocked using a non-invasive, transcutaneous technique. In one embodiment, a guided growth implant device, consisting of at least two locked pieces at time of surgical implant, can be non-surgically unlocked in-situ, thus halting the guided growth process on demand without requiring additional surgery. In another embodiment, a guided growth implant device can be unlocked using a magnetic or electromagnetic coupling technique. In another embodiment, a guided growth system consists of a device that is implanted to constrain/tether physeal growth and an external actuator tool that is used to non-invasively, non-surgically unlock the implanted device thus halting the guided growth process.
