    摘要： A system for stabilizing the vertebral column without requiring the excision of bone from the superior or inferior vertebrae or the resection of the adjacent anterior or posterior longitudinal ligaments. The system includes a stabilizing device and a deployment system composed of first and second coacting tools. The stabilizing device is made up of an expandable threaded insert and an expansion screw. The threaded insert is a hollow cylindrical member having a central cylindrical threaded bore, and a self tapping helical thread extending about the outer periphery of the member. The member is split at its proximal end in communication with the bore to form a pair of slots extending parallel to its longitudinal axis. The expandable insert is arranged to be screwed by the first tool into the intervertebral space between the superior and inferior vertebrae to a desired depth and with the slots oriented in a plane generally perpendicular to the longitudinal axis of the vertebral column. The first tool includes a pair of extending fingers which fit into the slots to achieve that end. When screwed in, the self-tapping threads cut into the cortical bone of the superior and inferior vertebrae contiguous to the intervertebral space, but not substantially into the cancellous bone. The expansion screw is tapered and arranged to be screwed into the internally threaded bore in the expandable insert by the second tool. The second tool fits into the first tool. When the expansion insert is screwed into the expandable insert it causes the slots of the expandable insert to open and thereby spread the superior and inferior vertebrae apart, thereby stabilizing the being's vertebral column.

    摘要翻译： 用于稳定脊柱的系统，而不需要从上或下椎骨切除骨或切除相邻的前后纵韧带。 该系统包括稳定装置和由第一和第二共同作用工具组成的展开系统。 稳定装置由可膨胀螺纹插入件和膨胀螺钉组成。 螺纹插入件是具有中心圆柱形螺纹孔的中空圆柱形构件，以及围绕构件的外周延伸的自攻螺旋形螺纹。 构件在其近端处与孔连通以形成平行于其纵向轴线延伸的一对狭槽。 可扩张插入物被布置成被第一工具螺纹连接到上，下椎骨之间的椎间空间到期望的深度，并且所述狭槽在大致垂直于椎骨柱的纵向轴线的平面中定向。 第一工具包括一对延伸的指状物，其配合到槽中以实现该目的。 螺纹拧入时，自攻螺纹切入与椎间空间相邻的上，下椎骨的皮质骨，但基本上不进入松质骨。 膨胀螺钉是锥形的并且被布置成通过第二工具拧入可扩张插入件中的内螺纹孔中。 第二个工具适合第一个工具。 当膨胀插入件拧入可膨胀插入物时，其使可扩张插入物的槽开口，从而使上下椎骨分开，从而稳定椎体的柱。

    摘要： A humeral prosthesis features improved anatomic attachment areas for tendon or bone. In the preferred embodiment, in contrast to existing devices, at least one set of tendon/bone attachment points are provided along a line, at least a portion of which is divergent with respect to the axis of the stem. One or more sets of attachment points may be further be provided along a line which is substantially parallel to the axis of the stem, resulting in a “T” “L” or “U” shape. Alternatively, attachment points having a changing degree of diversion with respect to the axis of the stem may be provided along a common, curved line. The attachment points may simply be apertures formed through the body of the implant though, in the preferred embodiment, the apertures are provided on raised tabs. An area of bone-ingrowth material may be provided adjacent the attachment points, and may include a separate fastening mechanism such as a threaded hole to receive a screw. A groove may also be provided in any embodiment to receive the biceps tendon. Particularly with respect to fractures, including multi- and ‘four-part’ fractures, means specifically intended for the rigid reattachment of the greater or lesser tuberosities may be provided separately or in conjunction with other sets of reattachment configurations.

    摘要： A tamp assembly for use in configuring bone cavity filler material within a bone cavity, in preparation for receiving an implant, includes a distal tamp portion which has a substantially constant cross-section over at least part of its length. A proximal tamp portion has a through bore extending through it with a size which is such that the proximal tamp portion is a sliding fit over the distal tamp portion. The proximal tamp portion has an exterior tamping surface extending from the through bore which faces generally towards the distal tamp portion. The assembly includes a hammer for transmitting impact to the bone cavity filler material which is contacted by the tamping surface of the proximal tamp portion.
