A sacroiliac (SI) joint implant assembly addresses SI joint dysfunction and degenerative sacroiliitis. The assembly includes a first implant body, a second implant body, and a piezoelectric layer positioned between them. The piezoelectric layer generates electrical charges when subjected to mechanical stress, stimulating bone growth and enhancing stability of the SI joint after surgery. The implant bodies may feature non-planar surfaces to distribute compressive and shear forces unevenly across the piezoelectric layer. The assembly can be secured using fasteners such as screws, pins, or brackets, and may include porous or fenestrated bodies made from materials like titanium or polymers. Some implant assemblies are designed for minimally invasive surgical procedures, with configurations that allow for precise placement using guide wires and imaging techniques. The assembly aims to stabilize the SI joint and promote bone fusion, leveraging the piezoelectric effect to improve the overall efficacy of the fusion procedure.
