1. A sacro-iliac joint stabilizing implant for implanting across a SI joint from a dorsal approach, comprising:
an implant body having a wafer configuration with a width dimension greater than a height dimension, the implant body including:
a central joint portion for placement across the SI joint;
an ilium portion on a first side of the central joint portion, the ilium portion sized and configured for implanting into an ilium when the implant is implanted across the SI joint from a dorsal approach;
a sacrum portion on a second side of the central joint portion, the sacrum portion sized and configured for implanting into a sacrum when the implant is implanted across the SI joint from the dorsal approach,
the ilium portion comprising an elongate ilium lumen extending from a distal opening to a proximal opening and having an ilium lumen longitudinal axis, the ilium lumen sized and configured to receive therein an ilium positioning guide, the sacrum portion comprising an elongate sacrum lumen extending from a distal opening to a proximal opening and having a sacrum lumen longitudinal axis, the sacrum lumen sized and configured to receive therein a sacrum positioning guide,
wherein with reference to a reference axis that is orthogonal to the ilium lumen longitudinal axis and the sacrum lumen longitudinal axis, the sacrum portion extends further proximally than the ilium portion, and the ilium portion extends further distally than the sacrum portion, and
with reference to the reference axis, the distal opening of the ilium lumen extends further distally than the distal opening of the sacrum lumen and the sacrum lumen extends further proximally than the ilium lumen; and
a distal portion that includes a sharpened distal end, the sharpened distal end having a tapered configuration with a first surface that tapers downward and distally from a top portion of the implant body and a second surface that tapers upward and distally from a bottom portion of the implant body.
