    摘要: A method for installing spine-stabilization components comprises directing a long plastic flexible tool through a sublaminar space of a human spine vertebrae inside the spinal canal. Such tool enters the sublaminar space of a particular one of the human spine vertebrae posteriorly from the intervertebral gap with an adjacent vertebrae. It exits the sublaminar space of the particular one of the human spine vertebrae posteriorly from the intervertebral gap with another opposite-side adjacent vertebrae. A suture is threaded through an eye of the tool. The suture is pulled back through the sublaminar space by withdrawing the long plastic flexible tool. The suture is detached from the long plastic flexible tool. A pulled-through part of the suture is attached to a spinal-fixation wire or cable. The suture is then usable as a pilot-line to draw the spinal-fixation wire or cable through the sublaminar space. The spinal-fixation wire or cable is used to anchor a spinal-fixation system.

    摘要: A percutaneous surgical tool comprises a cannula with an open slot at the distal end and a closed tip. A variety of articulated and solid tamps with different tip geometries are used to push bone aside to open up a void for filling. Bone pellets are rammed down the hollow interior, lumen, of the cannula by a tamper. A ramp inside the closed end causes the bone pellets to eject out to the side into a void to-be-filled. Variations in the shapes of the pellets and the ends of the tampers vary the orientations of the pellets as they are ejected through the end slot out from the cannula. One tamper with a sharp flat diagonal cut end can be twisted to push the rear end of the pellet harder sideways and out parallel to the cannula. Curved cannulas allow better access to all parts of the void to-be-filled.

    摘要: A prosthetic nucleus replacement comprises a solid flattened oval disk. The top surface of the disc is domed and has a crest that is about three times higher than the crest on the domed bottom surface. Both top and bottom surfaces are therefore convex. A peg extends down from the middle of the bottom domed surface and is used to pin the disc to the lower of two vertebrae it fits between. Metal markers are inserted into the peg and an outside edge of the disc so that radiographs can be used to determine the disc's in situ position. The prosthetic nucleus replacement is surgically implanted into the hollowed out intervertebral space through a flap cut in the natural annulus fibrosis. The lower vertebrae is prepared to receive the peg by clearing the material covering the top of the bone matrix. Bone cement is used around the peg to ensure a tight fit and immobile attachment of the disc to the lower vertebrae.
