Abstract
Intravertebral reduction systems are provided to restore a deformed or damaged vertebral body to a desired configuration. The reduction systems can include a plurality of reduction elements sequentially positionable in the intravertebral space for reduction of the same. The reduction systems can also include reduction elements that include a linear insertion configuration and are deformable transversely to the linear insertion configuration in the intravertebral space.
Claims37
An intravertebral reduction system, comprising:
- a plurality of reduction elements positionable in an intravertebral space adjacent one another in contact with bony tissue, wherein said plurality of reduction elements act one upon the other upon sequential positioning thereof in the intravertebral space to compress cancellous bony tissue and apply an outwardly directed corrective force in the vertebral body, wherein said plurality of reduction elements are selected in number to occupy a reduction element volume within the intravertebral space that obtains a desired vertebral reduction;
- voids between respective ones of said plurality of reduction elements;
- and
- means for fixing said plurality of reduction elements at said reduction element volume in engagement with one another in the intravertebral space in a manner maintaining the obtained vertebral reduction despite variations in spinal loading, said means including material filling said voids and locking said plurality of reduction elements relative to one another.

An intravertebral reduction system, comprising:
- a plurality of reduction elements positionable in an intravertebral space adjacent one another in contact with bony tissue, wherein said plurality of reduction elements act randomly and radially one upon the other upon sequential positioning thereof in the intravertebral space compressing cancellous bony tissue and applying an outwardly directed corrective force in the vertebral body, wherein said plurality of reduction elements are selected in number to occupy a reduction element volume within the intravertebral space that obtains a desired vertebral reduction;
- voids between respective ones of said plurality of reduction elements;
- and
- material filling said voids and fixing said plurality of reduction elements at said reduction element volume in engagement with one another in the intravertebral space in a manner maintaining the obtained vertebral reduction despite variations in spinal loading, said material locking said plurality of reduction elements relative to one another.

An intravertebral reduction system, comprising:
- a plurality of reduction elements positionable in an intravertebral space adjacent one another in contact with bony tissue, wherein said plurality of reduction elements include exterior surface means for facilitating engagement between adjacent reduction elements and for facilitating said reduction elements acting randomly and radially one upon the other upon sequential positioning thereof in the intravertebral space to compress cancellous bony tissue and apply an outwardly directed corrective force in the vertebral body, wherein said plurality of reduction elements are selected in number to occupy a reduction element volume within the intravertebral space that obtains a desired vertebral reduction;
- voids between respective ones of said reduction elements;
- and
- material filling said voids and fixing said plurality of reduction elements at said reduction element volume in engagement with one another in the intravertebral space for in a manner maintaining the obtained vertebral reduction despite variations in spinal loading, said material locking said plurality of reduction elements relative to one another.
