1. A method of fusing vertebrae and stabilizing sacro-iliac joints of a subject, comprising:
implanting at least a portion of a fusion cage between an S1 vertebra and an L5 vertebra;
implanting a first SI joint stabilizing member such that,
a cage end region of the first SI joint stabilizing member interfaces with a first lateral portion of the fusion cage,
the first SI joint stabilizing member extends through an S1 endplate,
an ilium end of the first SI joint stabilizing member is implanted in a first ilium and is posterior, lateral and caudal relative to the fusion cage, and
an intermediate region of the first SI joint stabilizing member that is between the ilium end and the cage end region is implanted across a first SI joint; and
implanting a second SI joint stabilizing member such that,
a cage end region of the second SI joint stabilizing member interfaces with a second lateral portion of the fusion cage,
the second SI joint stabilizing member extends through the S1 endplate,
an ilium end of the second SI joint stabilizing member is implanted in a second ilium and is posterior, lateral and caudal relative to the fusion cage, and
an intermediate region of the second SI joint stabilizing member that is between the ilium end and the cage end region of the second SI joint stabilizing member is implanted across a second SI joint.
