Abstract

Study Design Systematic review. Study Rationale Adult scoliosis is a common disorder that is associated with significantly higher pain, functional impairment, and effect on quality of life than those without scoliosis. Surgical spinal fusion has led to quantifiable improvement in patient's quality of life. However, for patients undergoing long lumbar fusion, the decision to stop the fusion at L5 or to extend to S1, particularly if the L5-S1 disc is healthy, remains controversial. Objective The aim of the study is to evaluate if fusion stopping at L5 increases the comparative rates of revision, correction loss, and/or poor functional outcomes compared with extension to the sacrum in adult scoliosis patients who require spinal fusion surgery. Materials and Methods A systematic review of the literature was performed using PubMed, the National Guideline Clearinghouse Database and bibliographies of key articles that evaluated adult scoliosis patients who required spinal fusion surgery and compared outcomes for fusions to the sacrum versus stopping at L5. Articles were included on the basis of predetermined criteria and were appraised using a predefined quality-rating scheme. Results From 111 citations, 26 articles underwent full-text review, and 3 retrospective cohort studies met all inclusion and exclusion criteria. Revision rates in subjects who underwent spinal fusion to L5 (20.8-23.5%) were lower in two studies compared with those with fusion extending to the sacrum (19.0-58.3%). Studies that assessed deformity correction used different measures, making comparison across studies difficult. No significant differences were found in patient-reported functional outcomes across two studies that used different measures. Conclusion The limited data available suggest that differences in revision rates did not consistently reach statistical significance across studies that compared spinal fusion to L5 versus extension to sacrum in adult scoliosis patients.
