    • A bone fixation system with variable z-axis translation is provided. The system includes an outer tulip coupled to a bone fastener via a screw retainer. An inner tulip is coupled to the outer tulip such that the inner tulip is longitudinally movably relative to the outer tulip. The inner tulip includes a lock that provides a seat for a connecting rod. The inner tulip together with a seated rod is permitted to translate along the z-axis inside the outer tulip when in an unlocked position. Also in the unlocked position, the bone fastener is free to angulate relative to the outer tulip. The z-axis position of the inner tulip and rod relative to the outer tulip is fixed in a locked position. Also, in the locked position, the bone fastener is locked with respect to the outer tulip. The system may be adjusted between the locked and unlocked positions by way of a set screw.
    • 提供了具有可变z轴平移的骨固定系统。 该系统包括通过螺钉保持器联接到骨紧固件的外部郁金香。 内部的郁金香联接到外部的郁金香,使得内部的郁金香相对于外部的郁金香纵向移动。 内部的郁金香包括提供用于连杆的座的锁。 当处于未锁定位置时,内部郁金香与座位杆一起被允许沿着外部郁金香的z轴平移。 同样在解锁位置,骨紧固件相对于外部的郁金香自由地成角度。 内部郁金香和杆相对于外部的郁金香的z轴位置固定在锁定位置。 此外,在锁定位置,骨紧固件相对于外部的郁金香被锁定。 系统可以通过固定螺丝在锁定位置和解锁位置之间进行调节。

    • A spinal facet bone screw and minimally invasive surgical method of implanting a facet screw to stabilize the spine are provided. The facet screw includes an elongated body portion having a head, a threaded portion and a distal threadless portion. A pair of flutes formed in the elongated body extends from the distal end across the threadless portion and into the distal end of the threaded portion. The flute creates a self-tapping cutting surface that includes a heel edge that is curved with respect to the outer surface. The method of implantation comprises making a minimally invasive incision on the side of the midline contralateral to the target facet joint and delivering the screw across the interspinous process using the adjacent spinous processes as guideposts. The facet screw system fixes juxtaposed facet articular processes to enhance spinal fusion and stability and the method provides for accurate, repeatable and easy implantation.
    • 提供了一种植入小平面螺钉以稳定脊柱的脊柱小骨骨螺钉和微创手术方法。 小平面螺钉包括具有头部,螺纹部分和远端无螺纹部分的细长主体部分。 形成在细长体中的一对凹槽从远端穿过无螺纹部分延伸到螺纹部分的远端。 笛子产生一个自攻切割表面,其包括相对于外表面弯曲的跟部边缘。 植入方法包括在目标小关节对侧的中线侧进行微创切口,并使用相邻的棘突作为方向将螺钉递送穿过棘突间过程。 小平面螺钉系统固定并列小关节关节突,以增强脊柱融合和稳定性,该方法提供准确,可重复和容易的植入。
