Deformity

Flatback syndrome

Loss of the lumbar curve (lordosis) so the person must flex the hips and knees to stand upright. It is often a consequence of prior surgery, degeneration, or a fusion that was performed without restoring alignment.

Flatback is an alignment problem. Treating the pain without restoring lordosis leaves the patient leaning forward. Revision plans often combine anterior column lengthening (ALIF) with posterior osteotomies when needed.

Dr. Li’s clinical research includes how ALIF versus TLIF restores the lordosis distribution index and how that relates to proximal failure — the kind of detail that separates a durable reconstruction from a short-lived one.
