Spinopelvic alignment in asymptomatic adults: a global meta-analysis quantifying heterogeneity and proposing a functional parameter hierarchy

Key Points

• This analysis aims to establish a hierarchy of spinopelvic parameters based on their stability and variability.
• Conducted a global meta-analysis of spinopelvic alignment parameters
• Evaluated the heterogeneity of parameters across asymptomatic adults
• Proposed a functional hierarchy from stable to variable elements
• Identified stable 'core' parameters and more variable 'adaptive' components in spinopelvic alignment.
• Highlighted the need for further research to validate underreported parameters related to the bicoxofemoral axis.
• Suggested that corrective strategies targeting stable parameters may enhance surgical outcomes.
