PROBLEM TO BE SOLVED: To provide a spinal screw assembly adapted to be secured to a vertebra for providing securement across at least two vertebrae.SOLUTION: An assembly includes a pedicle screw 102 having a substantially spherical head portion, a threaded shaft portion, and an engagement surface in the head portion for driving the screw into a vertebra, and a body member comprising a tower portion 106 having an open top, a break-away section for manipulation of the screw upon implantation into the vertebra, a base body 108 at a proximal region of the body member and a break zone 110 which acts as a transition between the base body and the tower portion. A resealably securable setscrew 302 within the body member secures and fully contains a rod 202 within the assembly. The break-away section remains completely outside a wound and is removed or broken off once the screw has been fully assembled inside the vertebra.COPYRIGHT: (C)2013,JPO&INPIT【課題】少なくとも2つの椎骨全体に固着を提供するために、椎骨に固着されるように適合される脊椎ネジアセンブリを提供する。【解決手段】アセンブリは、実質的に球状の頭部と、ネジ付シャフト部と、前述のネジを椎骨に螺入するための頭部内の係合表面とを有する椎弓根ネジ102と、開口上部を有する塔状部106と、椎骨への移植時のネジの操作のための離脱部分と、本体部材の近位領域における基体108と、基体と塔状部との間の移行部として作用する離脱ゾーン110とを備える本体部材と、を含む。本体部材内の再密閉できるように固着可能な止めネジ302は、前述のアセンブリ内のロッド202を固着し、完全に含む。ネジが椎骨内に完全に組み入れられると、離脱部分は、完全に創傷の外側に残り、除去または切り離される。【選択図】図3
