Abstract

The present invention discloses a prosthetic device for correcting deformity of the spine including a prosthetic device main body being inserted into an intervertebral disk, and having a variable height to correct deformity of the spine, and a control strip inserted into the prosthetic device main body, for controlling a height of the prosthetic device main body. A control strip insertion hole where the control strip is inserted and fixed is formed at the center portion of a height variable surface of the prosthetic device main body, an insertion hole is formed at the rear side portion of the prosthetic device main body which faces the variable surface, and an elastic cutting groove having a variable width is extended in a lateral direction from the control strip insertion hole to the rear surface, for dividing the variable surface into the upper and lower portions. The control strip is rotatably aligned in the control strip insertion hole of the prosthetic device main body, for enabling the variable surface to have an initial insertion position and a maximum height position by the rotation. Two prosthetic devices are inserted into the intervertebral disk of the spine, and fixed at a predetermined angle. As a result, the prosthetic device is easily safely inserted and fixed into a suitable position in a spine operation.
