摘要： A fracture alignment and retention device includes a plurality of spanning bars which are spaced about the extremity of the patient having a fractured long bone. Preferably, the spanning bars are located circumferentially about the extremity. At least three spanning bars are held in approximately 90 degree offset positions with respect to each other by two straps encircling the extremity. The straps are secured in place by a VELCRO-type fastener or other securing devices. Each spanning bar includes at least two pressure pads which are placed on the extremity on opposite sides of the fracture. Each pressure pad includes a threaded shaft which is threadably mounted at a central portion in a fixed bushing engaged in a slot defined in an uppermost surface of the spanning bar. One end of the shaft includes a knob and the opposite end is mounted on the pressure pad for causing movement of the pressure pad toward or away from the extremity in an axial direction along the shaft without rotation of the pressure pad. Rotation of knobs located at the end of the shaft controls the amount of pressure exerted against the extremity by the pressure pads and includes an indicator for noting relative positioning of a knob prior to and after turning of the knob.
摘要翻译：断裂对准和保持装置包括多个跨越条带的跨越条，所述跨越条围绕具有断裂的长骨的患者的末端间隔开。优选地，跨越条围绕末端围绕定位。至少三个跨越杆通过围绕末端的两个带相对于彼此保持在大约90度的偏移位置。带子通过VELCRO型紧固件或其他固定装置固定在适当的位置。每个跨越棒包括至少两个压力垫，其被放置在骨折的相对侧上的末端上。每个压力垫包括螺纹轴，该螺纹轴螺纹地安装在固定衬套中的中心部分，该固定衬套接合在跨越杆的最上表面中的狭槽中。轴的一端包括旋钮，并且相对端安装在压力垫上，用于使压力垫沿着轴的轴向方向朝向或远离末端移动，而不转动压力垫。位于轴端部的旋钮的旋转控制通过压力垫施加在末端上的压力的量，并且包括用于在旋钮旋转之前和之后注意到旋钮的相对定位的指示器。

摘要： An intramedullary rod system includes a guide rod and a tubular hollow intramedullary rod having an interior surface shaped, at least in a portion, complementary to that of the guide rod. The guide rod is first inserted through the medullary canal and then removed after sliding the tubular intramedullary rod over the guide rod. The guide rod is then aligned outside of the leg parallel to the hollow intramedullary rod for engagement at a distal end by bifurcated prongs with a drill bolt with which bifurcated prongs of the hollow intramedullary rod is simultaneously engaged. Screw holes are thereby aligned between the guide rod and the intramedullary rod at the distal end of the bone without the use of targeting. The hollow intramedullary rod is aligned with the guide rod by a lateral guide for accurate insertion through the guide rod of screws at the distal end of the hollow intramedullary rod.
摘要翻译：髓内杆系统包括导杆和管状空心髓内杆，其具有至少部分地与导杆的内表面互补的内表面。引导杆首先穿过髓管插入，然后将管状髓内杆滑动到导杆上之后取出。引导杆然后对准腿部平行于中空髓内杆的外侧，用于通过具有钻螺栓的分叉叉头在远端处接合，中空髓内杆的分叉叉与其同时接合。因此，螺钉孔在骨骼的远端处在引导杆和髓内杆之间对准，而不使用靶向。中空髓内杆通过侧向引导件与导杆对齐，以通过中空髓内杆的远端处的螺钉导杆精确插入。
