    • A bone fracture fixation plate juxta-articular stabilisation means comprises a plate with integral pin and tail parts, a plate specific jig, a plate and jig specific drill sleeve, a slotted head top loading screw, a plate positioner and a pin bender. This system can be used for fixation of most types of fractures involving the juxta-articular radius. The plate has a most juxta-articular row of screw holes in individually bendable and detachable extensions especially designed for very juxta-articular or the volar lip fractures. The plate also has bendable and detachable pin part and tail parts on either ends that allows the plate to be used with a chuck as a wire or drill bit and also have longer purchase into the bone with minimal soft tissue exposure. The plate and targeting assembly have plate positioning slots for wires in its juxta-articular part to allow adjustment in position of plate in longitudinal, transverse and oblique directions after initial fixation with wires without committing to a screw hole. This allows a very precise placement of the plate in the most ideal position. The targeting assembly can be mounted onto the plate prior to surgery thus reducing surgical step and time. The specific orientation of the screw holes in the shaft part of the plate orientates the screws such that when tendons apply forces across the fracture, the plate is wedged between screw and the bone rather than pushed away from the bone. Therefore, more aggressive physical therapy can be commenced earlier or plates with fewer screws in the proximal part can be used without compromising the strength of the fixation.
    • 骨折固定板关节稳定装置包括具有整体销和尾部的板,板专用夹具,板和夹具专用钻套,开槽头顶装载螺钉,板定位器和销弯曲器。 该系统可用于固定涉及关节半径的大多数类型的骨折。 该板具有单个可弯曲和可拆卸的延伸部分中最为关键的一排螺钉孔,特别设计用于非常关节或手腕唇裂。 该板还在两端都具有可弯曲和可拆卸的销部分和尾部部件,允许板材与卡盘一起用作线或钻头,并且在较少的软组织暴露下也可以更长时间地购入骨骼。 板和瞄准组件在其关节部分中具有用于线的板定位槽,以允许在初始用线固定之后在纵向,横向和倾斜方向上调整板的位置而不致螺丝孔。 这样可以非常精确地将板放置在最理想的位置。 靶向组件可以在手术之前安装在板上,从而减少手术步骤和时间。 板的轴部分中的螺孔的具体取向使得螺钉的方向使得当筋在穿过骨折时施加力时,板被楔入螺钉和骨之间,而不是被推离骨头。 因此,可以更早地开始更积极的物理治疗,或者可以使用近端部分中具有较少螺钉的板,而不会影响固定的强度。
