A flexible curve can be corrected with positioning and a fusion. A rigid curve cannot. PSO removes a wedge of bone including the pedicles so the spine can be closed into lordosis. It is powerful and it is reserved for patients whose life is limited by the shape of the spine.
Dr. Li’s case work includes L4 PSO and long constructs such as T4–pelvis when that is what standing balance requires. These are among the most demanding reconstructions in orthopaedic spine surgery.
What to expect
- A long anesthetic, neuromonitoring, and a hospital stay measured in several days.
- Blood management and an enhanced-recovery pathway are part of the plan, not an afterthought.
Recovery
- The first weeks are about standing, breathing, and wound healing.
- The first months are about living in a new, more upright posture — which itself takes practice.
