Dear Editor, We read with interest the article entitled “Biomechanical Stability of the
Sacroiliac Joint With Differing Implant Configurations in a Synthetic Model” by Andrew L …

METHODS An experimentally validated finite element model of the lumbar spine and pelvis
was used to simulate a fusion of the SI joint using various placement configurations of …

Purpose This study's objective was to assess biomechanical parameters across fused and
contralateral sacroiliac joints (SIJs) and implants during all spinal motions for both sexes …

Purpose The fusion of the sacroiliac joint (SIJ) is the last treatment option for chronic pain
resulting from sacroiliitis. With the various implant systems available, there are different …

We read the recent article by Sayed et al.[1] with interest. The authors report the results from
a cadaveric biomechanics study that evaluated sacroiliac (SI) joint motion after placement of …

Background: The sacroiliac joint (SIJ) is responsible for 15%–30% of chronic low back pain
and fusion is increasingly used to alleviate chronic SIJ pain in adults. However, questions …

Purpose The purpose of this study was to assess the stabilizing effect of a posterior joint
fixation technique using a novel cortical allograft implant in unilateral and bilateral fixation …

BACKGROUND CONTEXT: Sacroiliac joint (SIJ) fusion is an innovative surgery, yet
concerns exist that unilateral SIJ fusion may increase contralateral SI joint degeneration due …

OBJECTIVE S2-alar-iliac (S2AI) screw fixation effectively ensures stability and enhances
fusion in long-segment constructs. Nevertheless, pelvic fixation is associated with a high rate …

Background Sacroiliac joint (SIJ) is a known chronic pain-generator. The last resort of
treatment is the arthrodesis. Different implants allow fixation of the joint, but to date there is …
