| 1. A spinal correction system comprising:
a bridge member having an upper surface, an opposed lower surface, a front side, an opposed back side, a left end, and an
opposed right end, said bridge member defining a central longitudinal axis extending between said left end and said right
end;
a left fastener retaining portion extending from said bridge member left end and being laterally offset relative to said longitudinal
axis, said left fastener retaining portion having an upper surface, a lower surface, a front side, and a back side;
a right fastener retaining portion extending from said bridge member right end and being laterally offset relative to said
longitudinal axis, said right fastener retaining portion having an upper surface, a lower surface, a front side, and a back
side;
a left leg extending downwardly from said bridge member lower surface proximate said left end of said bridge member and inwardly
from said left fastener retaining portion, said left leg including a tapered distal free end defining a blade edge for insertion
into bone;
a right leg extending downwardly from said bridge member lower surface proximate said right end of said bridge member and
inwardly from said right fastener retaining portion, said right leg including a tapered distal free end defining a blade edge
for insertion into bone, said distal free ends of said right leg and said left leg being positioned in longitudinally spaced
relation; and
wherein each of said fastener retaining portions are proportioned so that when one of said left and right ends of a first
spinal correction system is positioned adjacent one of said right and left ends of a second spinal correction system, with
the longitudinal axis of the first spinal correction system being substantially aligned with the longitudinal axis of the
second spinal correction system, thereby defining a pair of adjacent ends, each of said fastener retaining portions extending
from said adjacent ends is positioned asymmetrical to said longitudinal axis with one of said sides facing one of said sides
of the other said fastener retaining portion extending from the other said adjacent end.
