    Abstract: A system and method facilitate insertion of a fusion implant into the intervertebral space of a spine. The fusion implant may have a first bone engaging surface and a second bone engaging surface. An attachment interface on an insertion tool allows the implant to be releasably secured to the insertion tool, so that the insertion tool may be detached from the implant without requiring a threaded coupling. The implant may be positioned in two different orientations with respect to the insertion tool to permit usage of two different techniques to insert the implant into the intervertebral space. A recessed support member in the implant creates gaps between bone facing surfaces and the vertebral bodies such that bone graft material may occupy the gaps. The implant includes embedded radiographic markers which facilitate radiographic detection of the orientation of the implant through the surrounding tissue.

    Abstract: A posterior vertebral stabilizer has a resilient member such as a linear spring, which operates in tension and compression. The resilient member may be kept straight by a stabilization rod extending through the spring, or by a telescoping assembly that encases the resilient member. The ends of the stabilizer are attachable to pedicles of adjacent vertebrae so that the stabilizer adds stiffness to control flexion and extension of the vertebrae. Two such stabilizers may be used, and may be connected together by a crosslink designed to limit relative rotation of the stabilizers. Thus, the stabilizers may restrict axial rotation and lateral bending between the vertebrae, while permitting stiffened flexion and extension. Such stabilizers help provide the stiffness of a healthy intervertebral disc. In the event that fusion of the joint becomes necessary, a set screw or other component may be used to further restrict flexion and extension.

    Abstract translation: 后椎骨稳定器具有弹性构件,例如线性弹簧,其在张力和压缩下操作。 弹性构件可以通过延伸穿过弹簧的稳定杆或通过包围弹性构件的伸缩组件保持直线。 稳定器的端部可附接到相邻椎骨的椎弓根,使得稳定器增加刚度以控制椎骨的屈曲和伸展。 可以使用两种这样的稳定​​剂,并且可以通过被设计成限制稳定剂的相对旋转的交联而连接在一起。 因此,稳定器可以限制椎骨之间的轴向旋转和侧向弯曲,同时允许加强的屈曲和伸展。 这种稳定器有助于提供健康的椎间盘的刚度。 在需要接头融合的情况下,可以使用固定螺钉或其它部件来进一步限制屈曲和伸展。

    Abstract: A guide assembly for forming a tunnel through a proximal end of a tibia includes a brace having a first end and an opposing second end. A template is mounted on the first end of the brace. The template is adapted to rest on a lateral or medial facet at a proximal end of the tibia. A tubular guide sleeve has a proximal end and an opposing distal end. The tubular guide sleeve is adjustably mounted on the second end of the brace such that when the template is disposed on the lateral or medial facet of the tibia, the distal end of the tubular guide sleeve can be selectively biased against a lateral, medial, or anterior side of a proximal end of the tibia.
