3. Choosing an upper instrumented vertebra of T9-T10 over T11-L2 will reduce mechanical complications in adult spinal deformity surgery

Selection of the upper instrumented vertebra (UIV) in adult spinal deformity (ASD) surgery involves a balance between preserving motion segments and minimizing supraphysiologic stress on the proximal non-instrumented segments. T9-10 are commonly selected though more distal segments of the thoracolumbar junction are sometimes targeted. We hypothesize that choosing an UIV of T9-T10 over T11-L2 will reduce mechanical complications in ASD surgery.
