    • The invention relates to a process and device for securing, elongating and compressing a spinal column, of simple design, which is easy and precise in use, leaving no projecting part. The process of the invention for straightening and supporting a spinal column consists in securing screwed implants (10) or hooks on either side of the curvature of the spin and interlinking them by at least two rods (20,21) designed to act as struts; said rods (20,21) are introduced longitudinally into grooves (113) perpendicular to the screw (120) fitted in the body (110) of the implants (10) or hooks and then fixed in the base of the grooves (113) by crimping resulting from the deformation of the sides of the groove (113) by the closing of its sides; said deformation is obtained via a conically-threaded nut (30) and a cylindrical male thread cut around the body (110) of the implants (10). Application: straightening and supporting the spinal column in the event of scoliosis or fracture, for example.
    • 本发明涉及一种简单设计的用于固定,伸长和压缩脊柱的方法和装置,其在使用中容易且精确,不留下突出部分。 用于校正和支撑脊柱的本发明的方法包括将旋转的植入物(10)或钩固定在旋转曲率的任一侧上并通过设计成用作支柱的至少两个杆(20,21)将它们相互连接; 所述杆(20,21)纵向引入垂直于嵌入在植入物(10)的主体(110)或钩中的螺钉(120)的凹槽(113)中,然后通过以下方式固定在凹槽(113)的基部中: 通过其侧面的闭合使槽(113)的侧面变形引起的卷曲; 所述变形通过锥形螺母(30)和围绕植入体(10)的主体(110)切割的圆柱形外螺纹获得。 应用:例如在脊柱侧弯或骨折发生时矫正和支撑脊柱。
