摘要： An elongated member forming a spinal support rod is implantable adjacent the spine of a patient and includes an axial span or spans for spanning respective spinal levels to promote efficacious spinal support/stabilization. The axial span manifests a double helical geometry. The axial span has a rod-like profile of a diameter similar to conventional spinal support rods used for lumbar spinal fusion, and provides for use across multiple spinal levels and with multiple adjustable attachment points for associated spine attachment devices, such as pedicle screws, to accommodate different patient anatomies.

摘要： Spinal stabilization devices, systems and methods are provided that include at least one pedicle screw (216,218) and at least one mechanism that supports three degrees of rotational freedom relative to the pedicle screw. The mechanism may include a universal joint mechanism or a ball (236,238) and socket (232,234) mechanism. The dynamic junction is advantageously incorporated into a spinal stabilization system that includes additional pedicle screw (s ), spherical element (s) and socket member (s) . Pedicle screws are disclosed that includes an upwardly extending collet (260) . The collet may include downwardly extending slots (270) that define deflectable segments (264) therebetween. The pedicle screw may include a preloaded set screw (274) that is maintained in position by an interference is advantageously formed on the set screw to prevent dislodgement of the set screw, e.g., during shipment and/or clinical placement of the pedicle screw. When a spherical element or other structure, e.g., a non-dynamic stabilizing element, is positioned around the collet, introduction of a set screw causes outward deflection of the upstanding segments into engagement with the spherical element. A snap ring (273) may be interposed between the collet and the spherical element to facilitate positioning therebetween.

摘要： An elongated member forming a spinal support rod is implantable adjacent the spine of a patient and includes an axial span or spans for spanning respective spinal levels to promote efficacious spinal support/stabilization. The axial span has an axially articulable geometry, and manifests an angulation mechanism along one or more transverse directions of at least seven degrees across a given spinal level. The angulation mechanism may be associated with joints between structural elements assembled in serial along the axial span, or via a common connection between such structural elements and a restraining element. Rotation between such structural elements can be global. The axial span may have a rod-like profile of a diameter similar to conventional spinal support rods used for lumbar spinal fusion, and provides for use across multiple spinal levels and with multiple adjustable attachment points for associated spine attachment devices to accommodate different patient anatomies.
摘要翻译：形成脊柱支撑杆的细长构件可植入患者脊柱附近并包括用于跨越相应脊柱水平以促进有效脊柱支撑/稳定的轴向跨度。轴向跨度具有轴向可关节的几何形状，并且沿着给定脊柱水平面上的至少七度的一个或多个横向方向显示成角机构。成角机构可以与沿着轴向跨度串联组装的结构元件之间的接头相关联，或者可以通过这些结构元件与限制元件之间的公共连接来联接。这种结构元素之间的旋转可以是全局的。轴向跨度可以具有类似于用于腰椎融合的常规脊柱支撑杆的直径的杆状轮廓，并且提供用于跨多个脊柱水平并且具有用于相关联的脊柱附接装置的多个可调节附接点以适应不同的患者解剖结构。

摘要： An elongated member forming a spinal support rod is implantable adjacent the spine of a patient, and includes an axial span or spans for spanning respective spinal levels to promote efficacious spinal support/stabilization. As with conventional spinal support rods used in connection with lumbar fusion and other related procedures, the elongated member extends in an axial direction, and is substantially dimensionally stable, both radially and axially. The elongated member is further capable of bending, flexing, and/or deflecting laterally (e.g., along any and/or substantially all transverse directions) to an extent that preserves at least some spinal motion. Such elongated members can include axial spans that manifest a radially segmented geometry relative to the axial direction, include a sleeve and a series of structural members or a coil spring enclosed within the sleeve, and/or include a coil spring and a restraining element passing at least partially through the coil spring.
