Abstract
Devices and related methods for the dynamic correction of spinal deformities are disclosed. The devices and methods are particularly useful for correcting an abnormal curvature of the spine. In one exemplary embodiment, a method for correcting deformity via a spinal implant that can include a polymer between or attached to a top and bottom plate, which can exist in a wedge-shaped configuration in order to apply asymmetric forces to the spinal column, is provided. The implant may be inserted between adjacent vertebrae comprising part of the abnormal curvature, thereby restoring the normal curvature of a spine.
Claims18
A spinal intervertebral disc implant device for alignment and/or realignment of a spinal column in more than one plane or axis comprising an elastic polymer component, wherein the elastic polymer component is capable of:
- (a) absorbing shock;
- (b) applying asymmetric force(s) to a vertebrae or vertebral element and adjacent vertebrae or vertebral element from within an intervertebral disc space by extension and/or contraction of one or more portions of the elastic polymer component;
- (c) aligning and/or realigning a spinal column;
- and
- (d) responding to loading and/or movement of the spinal column, and
- wherein a spring constant of the elastic polymer component remains steady after being implanted in or on the spinal column.
A method of treating spinal deformity comprising implanting an elastic device configured to be inserted between two spinal vertebrae, wherein a spring constant of the elastic device remains steady after being inserted between the two spinal vertebrae, wherein the elastic device is further capable of applying asymmetric forces to adjacent vertebrae to realign a vertebrae, vertebral element, and/or spinal column, wherein the asymmetric forces propagate through all or part of a spinal column in which the elastic device is implanted, and wherein the elastic device is capable of treating the vertebrae, vertebral element, and/or spinal column in both the sagittal and coronal planes within the cervical, thoracic, or lumbar vertebrae.
