When a patient arrives with low back pain, the goal is clear: identify the pain generators and assemble a treatment plan that reduces pain, improves function, and preserves the health of the structures involved. In this guide, I’ll walk through a practical framework you can apply in clinic, with a focus on anatomy, diagnostics, and a stepwise approach to treatment that includes conservative care, injections, and regenerative techniques.

The lumbar functional unit is a dynamic system. Each vertebral level interacts with the one above and below through a complex interplay of vertebral bodies, discs, lamina, facet joints, and the posterior ligaments. In this context, the concept of biodynamics and biotin—the posterior elements acting as stabilizers—becomes a useful framework for understanding where pain and instability originate and how we can address them with injections.
