Upper versus Lower Lumbar Lordosis Corrections in relation to Pelvic Tilt - An Essential Element in Surgical Planning for Sagittal Plane Deformity.
Retrospective study of a multicenter Adult Spinal Deformity (ASD) Database. ⋯ In the surgical planning for ASD, our data demonstrated significant correlational difference between corrections in the upper (L1-4) and lower (L4-S1) lumbar spine and PT changes. These calculations can be useful in planning sagittal plane corrections for ASD.

Retrospective longitudinal study. ⋯ The long-term consequences of LIV choice mostly affect levels distal to L3. If the LIV is mostly defined by the characteristics of the curve, one level caudally corresponds to +9 mm of back pain VAS at 7 years of follow-up. Surgeons may be aware of the long-term consequence of LIV choice and patients be informed.
