    ObjectiveTo evaluate the correlation of spinal sagittal imbalance and life quality.MethodsRadiographic analysis for 48 consecutive symptomatic patients with spinal sagittal imbalance was performed with posteroanterior and lateral standing radiographs. There were 12 males and 36 females with an average age of (66.2 ± 8.5) yrs. The measurement parameters included C7PL, thoracic kyphosis (TK), thoracolumbar kyphosis (TLK), lumbar lordosis (LL), pelvic tilt (PT), pelvic incidence (PI) and sacral slope (SS). Life quality was assessed with SF-36 questionnaire. Pearman's method was employed to analyze the correlation.ResultsMean C7PL was (44.7 ± 22.5) mm, TK (26.1 ± 13.1)°, TLK (11.9 ± 10.3)°, LL (23.5 ± 18.2)°, PT (32.1 ± 13.4)°, PI (57.4 ± 10.9)° and SS (22.5 ± 11.5)°. C7PL had a significant correlation with physical functioning (r = -0.428, P < 0.01) and general health (r = -0.428, P < 0.01). PI had a significant correlation with bodily pain (r = -0.374, P < 0.01), vitality (r = -0.303, P < 0.01), social functioning (r = -0.309, P < 0.01) and role emotional (r = -0.429, P < 0.05). TK had a significant correlation with physical functioning (r = -0.292, P < 0.05) and general health (r = -0.389, P < 0.01). LL had a significant correlation with physical functioning (r = 0.428, P < 0.01), general health (r = 0.340, P < 0.05) and vitality (r = 0.373, P < 0.01). PT had significant correlation with vitality (r = -0.385, P < 0.01) and social functioning (r = -0.417, P < 0.05). No significant correlation existed between TLK, SS and SF-36 categories.ConclusionC7PL, TK, LL, PI and PT are significant parameters correlating with quality of life. PI is the most important one affecting bodily pain. TK, LL and C7PL are the main parameters affecting general health. PI, PT and LL affect vitality the most. Correcting these parameters while treating sagittal imbalance is important for a better life quality.
