Articulating interbody cage and methods thereof

摘要

Disclosed herein are devices (100), systems and methods of use relating to articulating interbody cages. In one aspect, disclosed is an intervertebral device (100) for use in a human spine including an anterior end (104); a posterior end (102); and at least four peripheral walls (22,24,26). The peripheral walls (26) define an interior volume surrounding a midline of the device and include a superior wall (22), an inferior wall (24) and a pair of opposing, generally trapezoidal-shaped sidewalls. Each of the trapezoidal-shaped sidewalls (26) includes an internal hinge element (60) that is rotatable from a first configuration to at least a second configuration such that the device is expandable in first dimension. Each of the internal hinge elements includes an axis that is coplanar with the midline of the device.

主权项

1. A device comprising:
caudal and cephalad plates that are configured to be positioned adjacent to vertebral endplates within an intervertebral disc space; at least two lateral walls attached to the caudal and cephalad plates via an articulating mechanism, wherein at least one of the lateral walls includes a hinge element, wherein the device is configured to be inserted into the intervertebral disc space in a reduced dimension configuration and subsequently expanded to an enlarged dimension configuration, and wherein the hinge element is restricted to an under-center rotation position when the device is fully expanded to the enlarged dimension configuration.
