Core Tip

Core Tip: Sagittal alignment of the spine and pelvis was assessed for patients with or without retrograde of the adjacent vertebra body on postoperative X-rays. We concluded that the risk factors of the posterior slip of the proximal vertebra body after lower lumbar fusion are related to a higher pelvic incidence (PI) and distribution of lumbar lordosis. When a patient has a high PI and insufficient reconstruction of the lower lumbar spine, adjacent segment compensation via posterior vertebra body slippage is one of the factors that significantly affects surgical outcomes.
