Sacroiliac Joint Pain after Lumbo-Sacral Fusion: Incidence and Management Modalities.

Abstract
Background Data:
Incidence of sacroiliac dysfunction in a population suffering from low back pain (LBP) after
lumbosacral (LS) fusion is unknown. The underlying pathophysiology of SIJ pain may be increased by
mechanical load, iliac crest bone grafting, or a misdiagnosis of SIJ syndrome.
Purpose:
To evaluate the incidence of SIJ pain and the accuracy of diagnostic tools with utility of different
therapeutic modalities after lumbosacral fusion.
Study design:
A prospective case series study.
