    摘要: A polyaxial bone anchor including a housing and a bone screw. A bottom surface of the housing includes an aperture that defines an angulation limit of the bone screw for each azimuthal angle around a longitudinal axis of the housing. The aperture is V-shaped, with the V-shape having converging side walls that define a low-angulation direction near their intersection and a high-angulation direction opposite the low-angulation direction. In some cases, the angulation limit of the bone screw is generally constant over a range of azimuthal angles centered around the high-angulation direction. The housing may be modular, including tabs on one component that are plastically deformed to engage a lip on another component. During assembly, a mandrel advances longitudinally along a bore in the housing, and forces the tabs radially outward toward the lip to a radially outward plastically deformed state.

    摘要: The present invention relates to flexible members for stabilizing a spinal column and methods for making the flexible members. In one embodiment, a flexible member comprises an inner elastomeric member and an outer fabric layer situated securely around the inner elastomeric member. The inner elastomeric member has a first elasticity to provide the flexible member with a desired flexibility. In another embodiment, the flexible member includes an outer covering that defines an outer elastomeric member. The outer elastomeric member may be situated securely around the outer fabric layer with the inner elastomeric member, the outer fabric layer, and the outer elastomeric member having the common lengthwise axis and defining the body including the opposing first and second ends. The outer elastomeric member may have a second elasticity that is less than the first elasticity.
