Принадлежит: II Richard A. Kube

A spinal interbody fusion implant has an impact rod fitting that is configured and adapted to be connected to an impact rod during implantation of the implant. The implant also comprises one or more openings that are encircled by portions of the implant and that extend into the top of the implant and continue through to and out of the bottom of the implant. The top and bottom of the implant each have a load bearing footprint. Each of the load bearing footprints has a centroid that is closer to the leading end of the implant than to the trailing end of the implant. A method of implanting a spinal interbody fusion implant between two vertebrae of a spine comprises inserting the implant into a patient through a posterior incision and guiding the implant into a position between the two vertebrae using a pair of shims.

An intervertebral fusion cage having a plate pivotally attached thereto. The plate and cage are pivotally coupled but move independently of each other. The plate is made up of two smaller plate halves: a superior plate half and an inferior plate half Both plate halves form the larger plate. The plates are joined using a cross pin that provides a pivot point about which the plate halves rotate. The same pin also joins the plate halves to the cage, thus allowing the plate halves to pivot about the cage. It is believed that the device of the present invention will reduce the difficulties in placing a lateral plate down a port and manipulating it into position. Mating the plate to the cage will reduce the chances of micromotion and improve fusion rate, resulting in improved patient outcomes.

Selectively Expanding Spine Cage With Enhanced Bone Graft Infusion

Номер: US20130190875A1
Принадлежит: Coalign Innovations Inc

A selectively expanding spine cage has a minimized cross section in its unexpanded state that is smaller than the diameter of the neuroforamen through which it passes in the distracted spine. The cage conformably engages between the endplates of the adjacent vertebrae to effectively distract the anterior disc space, stabilize the motion segments and eliminate pathologic spine motion. Expanding selectively (anteriorly, along the vertical axis of the spine) rather than uniformly, the cage height increases and holds the vertebrae with fixation forces greater than adjacent bone and soft tissue failure forces in natural lordosis. Stability is thus achieved immediately, enabling patient function by eliminating painful motion. The cage shape intends to rest proximate to the anterior column cortices securing the desired spread and fixation, allowing for bone graft in, around, and through the implant for arthrodesis whereas for arthroplasty it fixes to endpoints but cushions the spine naturally.
