20130345755 | LOW PROFILE BONE STABILIZATION SYSTEMS - A low profile spinal stabilization system according to one embodiment includes an elongated fixation element having a socket. The system also includes an anchor element having a spherical end for insertion into the socket of the elongated fixation element, the spherical end having a plurality of petals separated by a plurality of radially arranged slots. The system further includes a locking element for insertion into the spherical end of the anchor element to lock the spherical end of the anchor element inside the socket of the elongated fixation element. | 12-26-2013 |

20140100612 | APPARATUS AND METHOD FOR ALIGNING A SPINE - The present invention broadly comprises an assembly for performing a gradual lateral spinal alignment of a spine. The assembly includes a toggle bolt that includes a shaft and a toggle wing, a rigid stabilizing rod with an orifice, a cable attached to the toggle bolt and a tube enclosing the cable and extending out of the patient's back. The toggle bolt extends through the stabilizing rod and is positioned against the misaligned spine. The toggle bolt is placed in a bore through the body of a vertebra and deployed, The attached cable is pulled using the stabilizing rod as a brace to pull the spine into alignment. The device allows the spine to be gradually placed into alignment helping to avoid trauma on the spine and surrounding tissue. | 04-10-2014 |
20140142633 | SPLAY CONTROL CLOSURE FOR OPEN BONE ANCHOR - Open implant closure structures include a helically wound guide and advancement flange form having splay control surfaces. Multi-start closures and closures with inner set screws have splay control contours for interlocking with cooperating flange forms of bone anchor receivers. Flange form heights, thicknesses and other geometry, such as splay control ramp angle may be varied. | 05-22-2014 |
20150119942 | SPLAY CONTROL CLOSURE FOR OPEN BONE ANCHOR - Open implant closure structures include a helically wound guide and advancement flange form having splay control surfaces. Multi-start closures and closures with inner set screws have splay control contours for interlocking with cooperating flange forms of bone anchor receivers. Flange form heights, thicknesses and other geometry, such as splay control ramp angle may be varied. | 04-30-2015 |
20160000487 | EXPANDING SPINAL ANCHOR - An anchor for a pedicle screw having an anchor body comprising a proximal end, a proximal portion, a distal portion, and a distal end, and a through-hole through the anchor body from the proximal end to the distal end. The through-hole defines a long axis of the anchor, and is provided with undersized female threads in the proximal portion and a reduced inner diameter in the distal portion. The reduced inner diameter causes expansion of at least the distal portion of the anchor body when a screw is inserted into the through-hole. The anchor is further provided with a plurality of ridges on an exterior surface of the anchor body, the ridges configured to reduce the likelihood of pullout when the anchor is inserted into a vertebra and a screw is inserted into the through-hole. | 01-07-2016 |
20160022320 | BONE ANCHOR CLOSURE PIVOT-SPLAY CONTROL FLANGE FORM GUIDE AND ADVANCEMENT STRUCTURE - Open implant closure structures include a helically wound guide and advancement flange form having pivot-splay accommodating and splay control surfaces with opposing load flanks in initial non-parallel relation. | 01-28-2016 |
