Abstract: A pedicle screw portion and a spine rod portion together form a hybrid fixation assembly of low profile form, especially in a dorsal direction. The pedicle screw portion includes a head with a threaded shaft extending therefrom. The spine rod portion includes a junction through which it is attached to the head and able to swivel about a swivel post relative to the head. In various embodiments, additional degrees of freedom, including rotation and pivoting, can be accommodated between the spine rod portion of the pedicle screw portion. A turndown screw with associated tulip head is configured to attach to a threaded bore in the head of the assembly to allow for extension dorsally and joining of the assembly with other spine rods. Various spinal stabilization and fusion procedures can be performed utilizing the assembly and future expansion is accommodated with addition of further stabilization hardware.

Abstract: An interbody fusion implant fits between adjacent vertebrae for fixation during fusion thereof. Upper bores extend into a cephalid surface of the implant and preferably include threads therein. A guide tool is removably attachable to the implant which supports guide bores along centerlines aligned with the upper bores in the implant. A drill can pass along these guide bores to form holes in a vertebra adjacent the cephalid surface of the implant which is precisely aligned with the upper bores. A hybrid screw then passes through these holes in the vertebra adjacent the cephalid surface and threads into the upper bores to secure the implant to the adjacent cephalid vertebra. Bone screws can also be used to secure the implant to caudal vertebra by passing through bores passing through the implant, such that the implant is securely mechanically fastened to both cephalid and caudal vertebrae adjacent the implant.
