P50. A Prospective, Multi-Center, Non-Randomized Evaluation of XLIF in the treatment of Adult Scoliosis: Mid-Term Clinical Outcomes

BACKGROUND CONTEXT: Surgical intervention in adult scoliosis patients has traditionally been by large open anterior and/or posterior procedures, which can be accompanied by unacceptable morbidity and risk to the patient. Minimizing patient morbidity, especially in high risk elderly patients with preexisting comorbidities, is critical to rapid recovery of these patients. Minimally invasive treatment of adult scoliosis can be achieved with the XLIF approach.
