Claim 14:
15. A surgical apparatus configured to treat a functional spinal unit of a living being, the functional spinal unit comprising a superior vertebral bone, an inferior vertebral bone and the intervertebral disc space positioned there between, the surgical apparatus comprising:
a non-implantable housing comprising a front side, an opposing back side, a first side, an opposing second side, and an internal cavity;
a non-implantable first arm at least rotatably coupled to the housing, the first arm extending from a proximal first portion to a distal second portion, the proximal first portion at least partially extending into the housing through an opening of the first side, the proximal first portion configured to rotate about a first axis of rotation relative to the housing;
a non-implantable second arm rotatably coupled to the housing, the second arm extending from a proximal first portion to a distal second portion, the proximal first portion of the second arm at least partially extending into the housing through an opening of the second side, the proximal first portion configured to rotate about a second axis of rotation relative to the housing, the first and second axes of rotation being offset from one another;
a non-implantable third arm configured to at least partially retract into the internal cavity of the housing, the third arm extending from a proximal first portion to a distal second portion thereof;
a first non-implantable tissue interface extension coupled with the distal second portion of the first arm;
a second non-implantable tissue interface extension coupled with the distal second portion of the second arm;
a third non-implantable tissue interface extension coupled with the distal second portion of the third arm;
a non-implantable adjustment mechanism at least partially contained within the housing, the adjustment mechanism configured to produce, upon actuation, a retraction of the third arm into the internal cavity, the proximal end surface of the third arm being retained within the internal cavity when the adjustment mechanism is any position; and
an implantable member comprising at least a first top surface, an opposing first bottom surface, and a side connecting the first top and the first bottom surfaces, the implantable member sized to be at least partially received within the intervertebral disc space; and
wherein:
i) the first, second and third non-implantable tissue interface extensions are configured to cooperatively form a perimeter of a channel, the channel sized to permit passage of at least a portion of the implantable member therethrough; and
ii) the adjustment mechanism comprising at least a first actuator that is positioned a greater distance from front side of the housing than at least one of the first rotational axis first arm or the second rotational axis of the second arm.
