    摘要： The present application is directed to tethering systems that provide a corrective force to one or more vertebral members. The tethering systems may include an elongated member with first and second sections. The sections are displaceable relative to each other to increase a length of the elongated member. The first section may be attached to a first vertebral member, and a second section may be attached to a second vertebral member. At least one tether may be attached to the elongated member. The tether may include a length to be attached to the first and second sections, and to a third vertebral member that is positioned between and laterally offset from the first and second vertebral members. The length of the elongated member may increase thus causing the tether to apply a corrective force to the third vertebral member.

    摘要翻译： 本申请涉及向一个或多个椎骨构件提供矫正力的束缚系统。 束缚系统可以包括具有第一和第二部分的细长构件。 这些部分可相对于彼此移位以增加细长构件的长度。 第一部分可以附接到第一椎骨构件，并且第二部分可以附接到第二椎骨构件。 至少一个系绳可以附接到细长构件。 系绳可以包括要附接到第一和第二部分的长度，以及定位在第一和第二椎骨构件之间并横向偏离第一和第二椎骨构件的第三椎骨构件。 细长构件的长度可以增加，从而使系绳向第三椎体构件施加矫正力。

    摘要： A spinal disc replacement surgical instrument includes a first contacting member positionable along an endplate of a first vertebra and a second contacting member positionable along an endplate of second vertebra. The second contacting member is moveable relative to the first contacting member. A handle assembly is coupled to the first contacting member and the second contacting member. At least one actuating member is positioned between the first contacting member and the second contacting member. The at least one actuating member is moveable by the hand assembly from a first position, wherein the first and second contacting members include an unexpanded configuration relative to one another for insertion in the spinal cavity, to a second position providing expanded configuration relative to one another. The actuating member is configured to displace at least one of the first contacting member and the second contacting member away from each other to move the first contacting member and the second contacting member between the first position and the second position. The first contacting member has a first distal end and the second contacting member has a second distal end. The first end has a first end shape configured to conform to a shape of the first vertebra and the second end has a second end shape configured to conform to a shape of the second vertebra. The first end shape and the second end shape are different shapes.
