    摘要： A method and an assembly for reducing a displaced vertebra and connecting the displaced vertebra to a spinal implant rod. The assembly has a reduction bolt with machine threads on one end and coarse threads on the other. A connection unit attaches the spinal rod to the reduction bolt, and until it is tightened, the connection unit allows the reduction bolt to slide within the connection unit. The connection unit includes a washer that rides against the side of the reduction bolt, and a nut is threaded onto the machine threads of the reduction bolt over a collar. The collar open is open at both ends and is of a size to readily slide over the reduction bolt. The posterior face of the collar has a notch to accept that portion of the lateral side of the washer as it presses against the reduction bolt. The notch is part of the open end of the collar into which is slide over the reduction bolt and down onto the connection unit. Arranged in this fashion, the nut can be tightened against the collar to move the displaced vertebra toward the longitudinal member. The third clamp can be tightened to secure the reduction bolt to the longitudinal member, and then the nut and the collar can be removed from the patient without the vertebra moving away from the longitudinal member.

    摘要翻译： 一种用于减少移位的椎骨并将移位的椎骨连接到脊柱植入物杆的方法和组件。 该组件具有一端的机螺纹和另一端的粗螺纹的减压螺栓。 连接单元将脊柱杆附接到减压螺栓，并且直到其被紧固为止，连接单元允许还原螺栓在连接单元内滑动。 连接单元包括一个靠在减压螺栓侧面上的垫圈，并且一个螺母被拧到减速螺栓的机械螺纹上。 套环打开在两端是开放的，并且具有容易在减压螺栓上滑动的尺寸。 轴环的后表面具有凹口，以在垫圈压靠减速螺栓时接纳垫圈侧面的那部分。 凹口是套环的开口端的一部分，在其中滑过减压螺栓并向下滑动到连接单元上。 以这种方式布置，螺母可以紧紧地靠在套环上，以使移位的椎骨向纵向构件移动。 可以拧紧第三夹具以将还原螺栓固定到纵向构件上，然后可以从患者身上取下螺母和套环，而不会使椎骨从纵向构件移开。

    摘要： A bone fixation apparatus having an elongated plate member with at least two pairs of circular openings and a series of openings positioned along the longitudinal plane of the plate member with the circular openings and the series of openings each having a central vertical axis. The circular openings and series of openings each form a cavity with walls extending between the upper and lower plate member surfaces with at least a plurality of the cavities having smaller diameter portions at the plate member upper and lower surfaces and a larger diameter portion therebetween. The cavities are configured in the shape of two inverted cones with matching base circles for allowing transverse and longitudinal angulation of an implanted bone screw. A plurality of bone screws each have a threaded first end portion adapted for implantation into a patient's bone mass and a generally ellipsoid shaped enlarged second end portion. A locking member connects to the second end portion of each bone screw for expanding the second end portion so as to grip the cavity wall of the plate member and for locking each bone screw into a selected position within the circular openings and series of openings of the plate member.

    摘要翻译： 一种骨固定装置，具有具有至少两对圆形开口的细长板构件和沿着板构件的纵向平面定位的一系列开口，其中圆形开口和一系列开口各自具有中心垂直轴线。 圆形开口和一系列开口各自形成具有在上板和下板构件表面之间延伸的壁的空腔，其中至少多个空腔在板构件上表面和下表面处具有较小的直径部分，并且其间具有较大的直径部分。 空腔被构造成具有匹配基圆的两个倒锥体的形状，用于允许植入骨螺钉的横向和纵向成角度。 多个骨螺钉各自具有适于植入患者骨块的螺纹第一端部部分和大致椭圆形的扩大的第二端部部分。 锁定构件连接到每个骨螺钉的第二端部，用于扩展第二端部部分，以便夹持板构件的空腔壁，并且用于将每个骨螺钉锁定在所述圆形开口和一系列开口内的选定位置 板材。

    摘要： The present invention relates generally to flexible guide wires, and, more particularly, to a flexible guide wire that can be attached to a surgical site and pulled taut to provide a guide for the introduction of instruments and implants to the surgical site, but cannot be pushed towards the surgical site without the wire bending so that there is no advancement of the tip of the flexible guide wire further into the surgical site or bony structure.

    摘要： Prostheses and methods for repair of a cervical fact joint. The articulating surfaces of the natural facets of the facet joint are removed only a sufficient amount to allow the insertion of flat or slightly curvilinear portions of protheses therebetween in an overlapping relationship. The portions are so inserted and the prostheses mounted by attachment to adjacent vertebrae. Also, a single natural facet may be similarly repaired with a single prosthesis.

    摘要： Methods and instrumentation for surgical procedures relating to preparation of vertebral bodies and a disc space for insertion of spinal implants is disclosed. One instrument is a shim having a blade and a shaft having a first end connected with the blade. The blade is inserted into a distracted disc space to maintain distraction during subsequent procedures. Another instrument is a driver for driving the blade of the shim into the distracted disc space. Various methods contemplate the use of these instruments to maintain disc space distraction during disc space preparation for receiving an implant.
