摘要：
The present invention relates to a vertebral body posterior approaching artificial disc for causing lordosis and capable of being inserted between adjacent vertebrae. The vertebral body posterior approaching artificial disc comprises: a body having a rectangular shape without a side, and inserted between adjacent vertebrae to support upper and lower vertebrae and provide the upper and lower vertebrae with elasticity and a support means including an upper plate support unit for supporting an upper plate of the body by being closely placed on the lower surface of the upper plate of the body, a lower plate support unit for supporting a lower plate of the body by being closely placed on the upper surface of the lower plate of the body, and a connection frame for connecting the upper plate support unit with one end of the lower plate support unit. According to the present invention, a vertebral body can be forwardly, backwardly, and laterally moved while lordosis is maintained. Moreover, a minimal invasive surgery (MIS) can be performed in a posterior of a vertebral body, so a patient can be rapidly recovered. Furthermore, an artificial disc inserted in a vertebral body is opened by using a distractor, and an artificial disc support means is fitted therebetween, so an operation can be simply performed and lordosis can be effectively maintained. In addition, the artificial disc is inserted while being overlapped, so a lateral width is relatively narrower than a forward and backward length and only a small part of a disc and annulus fibrosus thereof may be removed.COPYRIGHT KIPO 2016본 발명은 척추전만을 만들기 위한 척추체 후방접근 인공디스크에 관한 것으로, 인접한 추골 간에 삽입 가능한 인공디스크에 있어서, 인접한 추골 간에 삽입되어 상, 하부 추골을 지지하며 상, 하부 추골에 탄성력을 제공하는 ㄷ자 형상의 몸체 및 상기 몸체의 상판 저면에 밀착되어 상판을 지지하는 상판지지부와 몸체의 하판 상면에 밀착되어 하판을 지지하는 하판지지부 및 상판지지부와 하판지지부의 일단을 연결하는 연결프레임으로 구성되는 지지수단을 포함하는 것을 특징으로 하는 척추전만을 만들기 위한 척추체 후방접근 인공디스크를 제공한다.본 발명에 따르면, 척추전만(Lordosis)을 유지하면서 척추체의 전후, 좌우 움직임이 가능하다. 또한, 척추체의 후방(Posterior)에서 최소 침습 수술(Minimal Invas
