In a spinal fusion procedure, hardware is typically used to stabilize the spine while the bone graft fuses the vertebrae together. Patients with fusion surgery were considered to get better stability than those without fusion; hence, screws in fused spine might share lower strain and have higher torque. The presence of wear debris [23] was reported to induce osteolysis leading to screw loosening. Pseudarthrosis means false joint and refers to movement that occurs at the fused site. Dr. Jovita Anyanwu answered.
