Abstract: Provided is an interspinous fusion implant that is capable of fixing a vertebral body having a lesion by using hooking between spinous processes through a minimal incision without using a pedicle screw. The interspinous fusion implant includes an upper hooking member installed to be hooked with one spinous process and a lower hooking member installed to be engaged with another adjacent spinous process. The upper hooking member and the lower hooking member are coupled to each other and then fixed to each other through a fixing bolt after a distance between vertebral bodies having a lesion is reduced by using a separate mechanism.

Abstract: An artificial disc replacement to be inserted between adjacent vertebrae includes a U shaped disc body to support an upper and a lower vertebrae and to provide elasticity when inserted between adjacent vertebrae; a disc holder located inside of the disc body having protrusions engaging with upper and lower vertebrae through openings at the top and bottom of disc body and to prevent dislocation of the disc from adjacent vertebrae, wherein the protrusions engage with an upper and a lower vertebrae through openings at the top and bottom of artificial disc body; and two bumps each having a coupling blaze facing the upper or lower vertebrae, wherein the disc holder is insertable inside of the disc body and wherein each coupling blaze is engaged by rotating the disc holder.
