    • The present invention comprises the provision and use of a novel retainer which is slidably advanced to a desired fixation position within a bone tunnel, fixed in position within the bone tunnel (preferably by wedging and/or pinning) while applying a lateral force against the graft ligament so as to compressively hold the graft ligament against the sidewall of the bone tunnel, and which then, optionally, has the graft ligament secured thereto with a cap, whereby to secure the graft ligament to the retainer and hence additionally to the host bone. The present invention also comprises the provision and use of a novel retainer which is slidably advanced to a desired fixation position within a bone tunnel so as to apply a lateral force against the graft ligament so as to compressively hold the graft ligament against the sidewall of the bone tunnel, and which is then locked to the host bone as the graft ligament is simultaneously secured to the retainer, whereby to secure the graft ligament to the retainer and hence additionally to the host bone.
    • 本发明包括提供和使用新颖的保持器,该保持器可滑动地前进到骨隧道内的期望的固定位置,在骨隧道内固定就位(优选通过楔入和/或钉扎),同时对移植物施加侧向力 以便将移植韧带压缩地保持在骨隧道的侧壁上,然后可选地使移植韧带具有用盖固定到其上的移植韧带,由此将移植韧带固定到保持器并且因此另外固定到宿主骨。 本发明还包括提供和使用新颖的保持器,其可滑动地前进到骨隧道内的期望的固定位置,以便对移植韧带施加侧向力以将移植韧带压缩地保持在 骨隧道,并且随后将移植韧带同时固定到保持器上,然后将其锁定到宿主骨上,从而将移植韧带固定到保持器并因此另外固定到宿主骨。

    • An orthopedic swivel screw comprises a threaded shaft and a tissue retainer, which elements are held together by a swivel joint. By virtue of its design, the swivel screw can be installed into a bore in a bone by turning and either pushing or pulling the treaded shaft with a tool. Use of the swivel screw for repair of the ACL, in particular ligament replacement, eliminates or at least minimizes the twisting that typically occurs during conventional ACL repair surgery. In addition, tension of the ligament graft can be precisely adjusted by using the swivel screw in combination with a tension-adjusting device such as a split-nut fastener or a tension bolt. The split-nut is used in combination with any implantable bolt used in orthopedic devices. The split-nut, has two halves, slides down a threaded rod until a rig surrounding the two halves forces them together. The split-nut is then readily threaded tightly onto the threaded rod.
    • 矫形旋转螺钉包括螺纹轴和组织保持器,这些元件通过旋转接头保持在一起。 通过其设计,旋转螺钉可以通过转动并用工具推动或拉动踏板轴而安装到骨骼中的孔中。 使用旋转螺钉修复ACL,特别是韧带更换,消除或至少最小化通常在常规ACL修复手术期间发生的扭转。 此外,可以通过使用旋转螺钉与诸如剖分螺母紧固件或张紧螺栓的张力调节装置组合来精确地调节韧带移植物的张力。 拆分螺母与用于矫形装置的任何可植入螺栓组合使用。 分裂螺母有两个半部,沿着螺纹杆滑下,直到围绕两半的钻机迫使它们在一起。 然后将分离螺母容易地拧紧到螺纹杆上。
