Abstract

STUDY DESIGN: Literature review. OBJECTIVES: The aim of this study was to present updated information on the basic pelvic parameters associated with lumbar degenerative disease. SUMMARY OF LITERATURE REVIEW: Sagittal imbalance has been known to be related to a poor prognosis in almost all adult spine problems, including lumbar degenerative disease. MATERIALS AND METHODS: Review of the relevant literature. RESULTS: Pelvic incidence is a morphologic parameter of the pelvis. It influences lumbar lordosis and thoracic kyphosis, and determines the limitations of pelvic retroversion in sagittal imbalance. Pelvic tilt is a positional parameter of the pelvis, indicating the degree of compensation for sagittal imbalance. A C7-sagittal vertical axis >5 cm, pelvic tilt >20°, and pelvic incidence-lumbar lordosis mismatch are known to be independent factors predictive of poor outcomes. CONCLUSIONS: The C7-sagittal vertical axis, pelvic tilt, and pelvic incidence-lumbar lordosis mismatch should be considered when surgery is planned for a patient with degenerative lumbar disease.
