Disclosed is a universal elastic fixing rod, comprising a U-shaped deformation structure, torsion connecting plates (3), and cylinders (4). The U-shaped deformation structure comprises at least one vertical U shape (1) and a horizontal U shape (2). When both sides of the U-shaped deformation structure are fixedly connected to the torsion connecting plates (3), the other ends of the torsion connecting plates (3) are fixedly connected to the cylinders (4). When one side of the U-shaped deformation structure is fixedly connected to the torsion connecting plate (3), the other side of the U-shaped deformation structure is directly connected to the cylinder (4). The universal elastic fixing rod can realize the flexible movement of an operation segment in a sagittal view, such as forward bending, backward stretching, leftward and rightward bending and rotating moreover, the flexible movement is sufficient, and the postoperative elasticity attenuation resistance is high. The universal elastic fixing rod can be used for one or more segments of the spine, and can also be applied to the dynamic fixation of broken bones and dislocated joints. The universal elastic fixing rod solves the problem that the various dynamic fixations currently used within the spine cannot keep the sufficient flexible movement of the spine in various directions and have low elasticity attenuation resistances.Linvention concerne une tige de fixation élastique universelle, comprenant une structure de déformation en forme de U, des plaques de connexion de torsion (3) et des cylindres (4).
