    • The device comprises an intramedullar nail adapted to be driven into a hollow bone. The proximal terminal nail segment comprises an internal thread and a transversely penetrating longitudinal slot adapted to receive a screw to penetrate through the nail and to be screw-connected with the bone. The distal terminal nail segment comprises two transversely throughgoing holes each adapted to receive a screw to be screw-connected with the bone. An adjusting means comprises a bolt as adjusting member provided with an external thread screwed directly into the internal thread of the nail, or screwed into the internal thread of an insert in turn screwed into the internal thread of the nail, the bolt being adapted to be brought into direct or indirect engagement with the screw transversely penetrating through the longitudinal slot. By turning the bolt the screw may be pressed toward the distal end of the nail and displaced toward the same. The adjusting means or member may be inserted into the nail in rapid and simple manner after the nail has been driven into the hollow bone, and may be brought into a position, in which it engages the screw that transversely penetrates through the longitudinal slot. The entire adjusting means is adapted to remain inside the nail, until such time as the nail is removed from the hollow bone.
    • 该装置包括适于被驱入中空骨的髓内钉。 近端终端钉部分包括内螺纹和横向穿透的纵向狭槽,其适于接收穿过钉子并与骨螺纹连接的螺钉。 远端终端钉段包括两个横向通孔,每个孔适于接收与骨螺旋连接的螺钉。 调节装置包括作为调节构件的螺栓,该调节构件设置有直接拧入到钉的内螺纹中的外螺纹,或螺纹连接到插入件的内螺纹中,螺钉连接到钉的内螺纹中,螺栓适于 与横向穿过纵向狭槽的螺钉直接或间接接合。 通过转动螺栓,可以将螺钉压向钉子的远端并朝向同一位置移动。 在钉子已经被驱动到中空骨中之后,调节装置或构件可以以快速且简单的方式插入到钉子中,并且可以进入与横向穿过纵向槽的螺钉接合的位置。 整个调节装置适于保持在指甲内,直到指甲从中空骨骼移除为止。
