Evaluation of the IFuse Bedrock Technique in Association with Posterior Lumbosacral Fusion with Iliac Fixation.
The purpose of this study is to describe the impact of the iFuse Bedrock technique to decrease post-operative pains in patients who underwent multilevel posterior lumbosacral fusion.
• Subject scheduled for open posterior lumbosacral arthrodesis (including at least the following three vertebrae: L4, L5 and S1) associated with a sacroiliac fusion procedure and iliac fixation (thoracolumbar fusion procedures extended to sacrum are eligible in the study);
• Insertion of at least 1 iFuse-3D implant according to the iFuse Bedrock technique (uni- and bilateral insertion are eligible);
• Subject who preoperatively responded positively to pain provocation tests for SIJ dysfunction with or without a positive SIJ infiltration test;
• Patient with a degenerative sacroiliac joint disease requested a fusion procedure;
