Posterolateral Mis Fusion for Degenerative Instability

This presentation explores lumbar spinal stenosis and the evolution of minimally invasive treatments, focusing on fusion techniques for patients with instability. The speaker reviews the stages of spinal stenosis, common symptoms like neurogenic claudication, and current interventions including MILD, Vertiflex, and interspinous fixation devices. While mild and Vertiflex address decompression, they lack stability for advanced cases. The discussion emphasizes posterolateral minimally invasive fusion with devices such as Minuteman, which restore alignment, lift disc height, and achieve standalone fixation with reduced tissue damage and lower infection risk. Clinical cases and biomechanical data demonstrate improved fusion rates, pain reduction, and functional outcomes.
