Abstract
An expandable cage for a spine includes an upper structural body, a lower structural body, a main frame having control mechanism insertion holes defined through one side and the other side in the longitudinal direction thereof, respectively, a sagittal balance control unit coupled to one side of each of the upper structural body and the lower structural body to control a sagittal balance of a spine by adjusting a spacing distance between the upper structural body and the lower structural body, and a coronal balance control unit coupled to the other side of each of the upper structural body and the lower structural body to control a coronal balance of a spine by controlling a gradient of the upper structural body and the lower structural body by lifting or lowering the other side of each of the upper structural body and the lower structural body.
