1. A method for trans-iliac lumbar fusion, the method comprising:
- creating an insertion path from an anterolateral region of a lumbar vertebra L5, in a caudal direction through the intervertebral disc into and through an opposite anterolateral interior region of a sacral vertebra S1, through the sacro-iliac joint, and terminating in the ilium;
providing a bone fixation implant comprising an elongated implant structure; and
inserting the bone fixation implant through the insertion path from the anterolateral region of a lumbar vertebra L5, in a caudal direction through the intervertebral disc into and through the opposite anterolateral interior region of a sacral vertebra S1, through the sacro-iliac joint, and terminating in the ilium.

Abstract
Assemblies of one or more implant structures make possible the achievement of diverse interventions involving the fusion and/or stabilization of lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. The representative lumbar spine interventions, which can be performed on adults or children, include, but are not limited to, lumbar interbody fusion; translaminar lumbar fusion; lumbar facet fusion; trans-iliac lumbar fusion; and the stabilization of a spondylolisthesis.

6. A method for trans-iliac lumbar fusion, the method comprising:
-
creating a first insertion path entering from a left posterior region of the iliac spine of the ilium, angling in a cranial direction through the SI-Joint into and through the sacral vertebra S1, and terminating in a right anterolateral region of a lumbar vertebra L5; creating a second insertion path entering from a right posterior region of the iliac spine of the ilium, angling in a cranial direction through the SI-Joint into and through the sacral vertebra S1, and terminating in a left anterolateral region of a lumbar vertebra L5; inserting the first implant structure through the first insertion path from the left posterior region of the iliac spine of the ilium, angling in a cranial direction through the SI-Joint into and through the sacral vertebra S1, and terminating in the right anterolateral region of the lumbar vertebra L5; inserting the second implant structure through the second insertion path from the right posterior region of the iliac spine of the ilium, angling in a cranial direction through the SI-Joint into and through the sacral vertebra S1, and terminating in the left anterolateral region of the lumbar vertebra L5, the first and second implant structures crossing each other in transit through the intervertebral disc.
