1. An insertion instrument for inserting a modular intervertebral fusion device or components thereof into an intervertebral space, the insertion instrument comprising:
a superior arm mounted on a superior support such that the superior arm extends from the superior support; and
an inferior arm mounted on an inferior support such that the inferior arm extends from the inferior support, wherein
the superior and inferior supports are mechanically coupled to each other whereby: the superior and inferior arms extend in generally a same direction such that, in use, the distal end of each of the superior and inferior arms engages at a respective location on a modular intervertebral fusion device or component thereof; and the superior and inferior supports rotate relative to each other to provide relative rotation of the superior and inferior arms, whereby there is movement together and apart of the superior and inferior arms at their distal ends, and
one of the superior and inferior arms is an unarticulated arm which is unarticulated between its distal end and the respective one of the superior and inferior supports, and wherein the other one of the superior and inferior arms is an articulated arm which is articulated between its distal end and the respective one of the superior and inferior supports,
the articulated arm comprises a proximal portion, a distal portion and a hinge, the proximal portion extending from the respective one of the superior and inferior supports, the hinge rotatably coupling the proximal and distal portions to each other, and the distal portion extending from the hinge to the distal end of the articulated arm whereby the distal end of the articulated arm rotates towards or away from the distal end of the unarticulated arm,
the unarticulated arm is immovably mounted on the respective one of the superior and inferior supports, and
the proximal portion of the articulated arm is immovably mounted on the respective one of the superior and inferior supports.
