Question

A 58-year-old male with adult spinal deformity presents after multiple operations involving his lumbar spine. He is neurologically intact without weakness or sensory deficits, but he continues to complain of worsening back pain and fatigue from basic activities of daily living. He is referred to a new Orthopaedic spine surgeon who consents the patient for a revision surgery with planned Smith Peterson osteotomies to correct his sagittal imbalance. If the patient has a radiographic pelvic incidence of 60° and a thoracic kyphosis of 35°, how much lordosis should the surgeon plan to achieve with the correction in the lumbar spine?
