1. An anterior cervical fixation plate for fixating portions of a cervical spine to facilitate bone fusion; said anterior cervical fixation plate comprising:
a first portion having a first surface, a second surface opposite and spaced apart from said first surface of said first portion, a first side, a second side opposite and spaced apart from said first side of said first portion, a third side, a fourth side opposite and spaced apart from said third side of said first portion, and a first axis extending from said third side of said first portion to said fourth side of said first portion; said first surface of said first portion includes a first fastener opening and a second fastener opening; each of said first fastener opening and said second fastener opening is aligned along said first axis; each of said first fastener opening and said second fastener opening extends from said first surface of said first portion to said second surface of said first portion;
a second portion having a first surface, a second surface opposite and spaced apart from said first surface of said second portion, a first side, a second side opposite and spaced apart from said first side of said second portion, a third side, a fourth side opposite and spaced apart from said third side of said second portion, and a second axis extending from said third side of said second portion to said fourth side of said second portion; said first surface of said second portion includes a third fastener opening and a fourth fastener opening; each of said third fastener opening and said fourth fastener opening is aligned along said second axis; each of said third fastener opening and said fourth fastener opening extends from said first surface of said second portion to said second surface of said second portion; and
a bridge having a first surface, a second surface opposite and spaced apart from said first surface of said bridge, a first side, and a second side opposite and spaced apart from said first side of said bridge; said bridge is located between said first portion and said second portion; said first side and said second side of said bridge each extends from said second side of said first portion to said first side of said second portion; said second side of said first portion, said first side of said second portion, and said first side of said bridge define a first window; said second side of said first portion, said first side of said second portion, and said second side of said bridge define a second window; a distance between said first and second windows is less than a distance between said first side of said first portion and said second side of said second portion; said first side of bridge forms a base of said first window; said base of said first window defining a narrowest portion of said first window and a width of said first window increases as a distance increases outwardly from said base of said first window; said second side of bridge forms a base of said second window; said base of said second window defining a narrowest portion of said second window and a width of said second window increases as a distance increases outwardly from said base of said second window.
