Lateral lumbar interbody fusion versus single position prone transpsoas approach: A comprehensive bibliometric analysis

LLIF represents a mature surgical approach with a strong evidence base while PTP demonstrates accelerating research interest, with growth trajectories exceeding those of LLIF during comparable developmental stages. Based on current publication trends and thematic evolution, future research on PTP should prioritize rigorous comparative studies, long-term outcome evaluations, cost-effectiveness analyses, and patient-centered outcome research to strengthen the evidence base and guide clinical adoption.
