    摘要: This disclosure is directed to a method capable of maintaining the fatigue performance of a bone-engaging implant after surface texturing through the imparting of a residual compressive stress. A residual compressive stress is imparted via peening or another process. The peened surface is then roughened to improve mechanical adhesion for bone fixation via grit blasting or another process. The depth of penetration of the roughened texture is less than the depth of the residual compressive stress.

    摘要: A spinal stabilization system includes a first stabilization member and a second stabilization member engaged to one another in end-to-end fashion. A coupling system adjustably secures the stabilization members in axial position relative to one another while allowing the relative axial positioning to be adjusted to accommodate growth or other condition or arrangement.
