Abstract
A method of percutaneous implantation of a pedicle screw system comprising the steps of implanting a first pedicle screw assembly in a first vertebra, the first pedicle screw assembly including a first coupling element connected with a first extension defining a first space and implanting a second pedicle screw assembly in a second vertebra, the second pedicle screw assembly including a second coupling element connected with a second extension and intersecting at least one a portion of the second extension with the first space.
Claims24
A system for percutaneous implantation into bone, the system comprising:
- a first pedicle screw assembly including a first coupling element connected with a first extension defining a first space having a first width therebetween;
- and
- a second pedicle screw assembly including a second coupling element connected with a second extension defining a second width between exterior surfaces thereof;
- wherein the first width is greater than the second width so that the second extension can fit within the first space.
A method of percutaneous implantation of a pedicle screw system comprising the steps of:
- implanting a first pedicle screw assembly in a first vertebra, the first pedicle screw assembly including a first coupling element connected with a first extension defining a first space;
- and
- implanting a second pedicle screw assembly in a second vertebra, the second pedicle screw assembly including a second coupling element connected with a second extension;
- and
- intersecting at least one a portion of the second extension with the first space.
