Easily implantable and stable nail-fastener for skeletal fixation and method
Abstract:
An intramedullary nail (20) defining a bore (34) is inserted into a medullary canal (26) of a bone (24). A threaded fastener (22) has a compression portion (48) presenting a compression portion diameter (DCP) and a threaded portion (50) presenting a threaded portion diameter (DTP). The fastener (22) extends through a near cortex hole (40) and/or a far cortex hole (42), and the threaded portion (22) threadedly engages the bore (34). A compression transmission device (54) is disposed between a head (44) of the fastener (22) and the intramedullary nail (20) for transmitting the compressional load of the threaded fastener (22) to the intramedullary nail (20). An interior space of the compression transmission device (54) is greater than the compression portion diameter (DCP) providing space about the threaded fastener (22) for allowing the fastener axis (A) to be variously disposed relative to the interior space.
Abstract(Chinese):

限定孔（34）的髓内钉（20）插入到骨（24）的髓管（26）中。 螺纹紧固件（22）具有呈现压缩部分直径（DCP）的压缩部分（48）和呈现螺纹部分直径（DTP）的螺纹部分（50）。 紧固件（22）延伸穿过近皮质孔（40）和/或远皮质孔（42），并且螺纹部分（22）螺纹地接合孔（34）。 压缩传动装置（54）设置在紧固件（22）的头部（44）和髓内钉（20）之间，用于将螺纹紧固件（22）的压缩载荷传递到髓内钉（20）。 压缩传动装置（54）的内部空间大于围绕螺纹紧固件（22）提供空间的压缩部分直径（DCP），用于允许紧固件轴线（A）相对于内部空间被各种布置。
