Key Points

To compare the rate of distal junctional problems (DJPs) between L3 and L4 pedicle subtraction osteotomy (PSO).
Comparison of rates of DJPs between L3 and L4 PSO
Assessment of multirod configurations
Evaluation of lumbar lordosis distribution
L4 PSO resulted in a lower rate of DJPs compared to L3 PSO
Physiological distribution of lumbar lordosis may influence DJP rates
