In vivo derotation growth-friendly spine implant system

Abstract

An in vivo derotation growth-friendly spine implant system includes: a rod; first fixing units arranged at both ends of the rod, respectively; and a twisting assembly comprising a second fixing unit and a rotating assembly. The rotating assembly wraps an outer side of the rod; the second fixing unit is arranged in a middle part of the rotating assembly, and the two are detachably connected; both ends of the rotating assembly are connected to the rod; the rotating assembly comprises a connecting ring, a connecting block, a first twisting unit, and a second twisting unit. The rotating assembly is connected to a spine through the second fixing unit, a twisting force is applied to the rotating assembly, and a strong anti-rotating force is applied to a vertebral body through the second fixing unit, such that the rotation of the vertebral body is corrected, and thus scoliosis is corrected.
