Abstract
Described here are deformable, monolithic, stabilization implants suitable for use within bone and between bones to fuse vertebral bodies, to repair herniated discs, or to repair spinal compression fractures. The implants are introduced into a chosen site at a first, smaller height and then plastically deformed to achieve a second, but unique, pre-selected, larger height. Variations of the device provide one or more specific larger heights. The devices are suitable as intervertebral spinal fusion implants for the immobilization of adjacent vertebral bodies. Methods of and instruments for deployment of the implants are also described. Also described are variations of the device suitable as sizing instruments.
Claims7
An orthopedic stabilizing device for placement in an interosseous space defined by adjacent bony surfaces, comprising a plastically deformable monolithic body that:
- a.) is expandable along a height axis between a first smaller height to a second larger expanded height by plastic deformation of the monolithic body, and
- b.) has first and second matchable, partial columns that are not in contact with each other at the first height and are operative to engage each other only at the second height to form a supporting structure along the height axis.
An orthopedic stabilizing device for placement in an interosseous space defined by adjacent bony surfaces, comprising a plastically deformable monolithic body expandable only along a height axis and expandable between a first smaller height to a second larger expanded height by plastic deformation of the monolithic body.
