Introduction And Hypothesis:
Optimal choice of the lower instrumented vertebra in the management of adult spinal deformity that include lumbosacral junction is still unclear. It is therefore possible to stop fixation in S1 but also lower (S2AI or iliac screws) in order to reduce the risk of implants pullout. In such situations, mechanical solicitations can lead to secondary degradation of sacro-iliac joints.
Technique And Results:
Based on triangular pelvic fixation described for pelvic trauma, a posterior only fixation that combine S1 screws, iliac screws and sacro-iliac implants can be performed.
Discussion:
We are describing here the operative technique of this « bedrock » fixation under fluoroscopic guidance and its preliminary results about 15 patients.
Level Of Evidence:
IV.
