Management
In a biomechanical cadaver study [PMID:25705956], posterior implant placement in sacroiliac joint fusion demonstrated significantly greater reduction in flexion-extension, lateral bending, and axial rotation compared to transarticular placement techniques.
The study suggests that the trajectory of SI joint fusion implants, specifically posterior placement, may play a crucial role in achieving better biomechanical stability [PMID:25705956], potentially leading to improved clinical outcomes.
Complications
While not explicitly detailed in the study [PMID:25705956], variations in implant placement techniques could influence biomechanical stresses, potentially affecting complication rates such as implant loosening or joint stiffness post-surgery.
