Introduction: Both sagittal imbalance and sarcopenia affect performance of daily activities and mortality in the elderly; however, little is known regarding their relationship.
Objectives: The aim of this study was to analyze the association between sarcopenia and sagittal imbalance.
Methodology: This study included 71 female patients aged between 60 and 85 years. Entire-spine radiography was used to measure radiological parameters. A bioelectrical impedance analyzer was used to measure the skeletal muscle mass index (SMI). Gait velocity (GV), and hand grip strength (HGS) were examined as well. Lumbar spine magnetic resonance imaging (MRI) was employed to measure the functional cross-sectional area (FCSA) and fat signal fraction (FSF) of the paraspinal muscle as well. The subjects were grouped as sagittal imbalance (sagittal vertical axis [SVA]?>?50 mm; SI group) and balance (SVA?≤?50 mm; SB group).
Results: The SI group patients were significantly older and had a lower hip BMD than the SB group patients (p?=?0.001 and 0.047, respectively). In addition, the SI group showed significantly lower GV, HGS, and SMI than the SB group (p?
Conclusion: Sarcopenia and fatty degeneration of paraspinal muscle are closely related to sagittal imbalance in the elderly.
