Evaluating the Impact of Spinal Osteotomy on Surgical Outcomes of Thoracolumbar Deformity Correction

In cases of adult spinal deformity (ASD) with severe sagittal malalignment, the use of osteotomies may be necessary in addition to posterior fusion. However, few data exist describing the impact of osteotomies on complications and quality outcomes during ASD surgery. We queried the MarketScan database to identify patients who underwent ASD surgery in 2007–2016. Patients were stratified according to whether or not an osteotomy was used in the index operation. Propensity score matching was used to mitigate intergroup differences between osteotomy and nonosteotomy groups. Patients
