Abstract
【解決手段】長手方向軸線に沿って延びかつステムおよびヘッドを備えた細長爪を有している、大腿を修復するファスナに使用する骨髄内ロッド。ヘッドには、ファスナを受入れるための、前記長手方向軸線に対して傾斜して一軸線に沿って延びている孔が設けられている。ヘッドには、前記孔の軸線を、ヘッドに対する第1傾斜位置からヘッドに対する第2傾斜位置までピボット回転させる機構が支持されている。前記ロッドおよびファスナを使用する方法も提供される。
【選択図】図1
Description
現在入手できる爪には、大腿爪を横断して大腿骨頭内に充分な固定強度を達成する静止傾斜ねじが設けられている。また、爪には、オーバースリーブを用いて(または用いることなく)、転子下領域およびこの下の骨折部位の制御された(または制御されない)動的圧縮を可能にするスロットが設けられている。しばしば、大腿骨頸骨折、転子間骨折および転子下骨折の治療器具は爪の種々の静止角を有し、このため、これらの静止角に適合するための多数の在庫を必要とする。
添付図面は例示のみを目的とするものであって、いかなる意味においても本発明の開示範囲を制限するものではない。
セグメント形部分102bは、内側弧状面105から形成できる。凹部102の他の側すなわちセグメント形部分102bとは反対側には、第1棚部107、第2棚部108および第3棚部109を形成できる。各棚部は、セグメント形部分102bの内側弧状面105よりも半径方向内方に位置し、長手方向軸線66に対して徐々に小さい半径を有する(図11−図13参照)。図4、図9および図10に示すように、任意であるが、第1棚部107の近位側部分には雌ねじ111を設けることができる。第1棚部107から第2棚部108へと半径方向内方に延びる肩部112を形成できる(図13参照)。図11に示すように、第3棚部は横方向横断開口93に当接できる。ヘッド67の近位端の近位側開口103には横断方向に整合したスロット110が設けられている。これらのスロット110は、目標骨内に爪62を配置するときまたは爪を操作するときに、爪62と、挿入ジグ標的器具または他の適当な器具とを整合させるためのものである。
上記説明から理解されようが、骨髄内爪の固定特性とスライド圧縮ねじの利益とを結合した、大腿骨折を治療する装置が提供される。本発明の装置は、これまで2つ以上の器具を必要とした種々の大腿骨折を治療する単一器具を提供する。この器具は、種々の大腿骨折および大腿骨切り部の治療に使用でき、かつ病院および製造業者が整形外科器具の種々の在庫を低減することを可能にし、したがってコストを低減させることを可能にする。本発明の器具は、医者が、移植後に骨折または骨切り部をより好ましい位置に移動させることを可能にし、例えば、大腿骨頸または転子間骨折部のスライド圧縮することを可能にする。本発明の装置は、医者が、大腿骨頭内に延びる近位側固定ねじの角度を変えることを可能にし、これは、大腿骨髄内管内への大腿ロッドの挿入の前または後に行うことができる。
