Demographic data, operative parameters, spinopelvic parameters, functional outcomes, and complications were collected.Results: Health-related quality of life scores showed a better outcome at 6 months and last follow-up visits in the MRP and MRL groups which were noted on different domains of Scoliosis Research Society-22 questionnaire, 36-item Short Form Health Surve, and Oswestry Disability Index scores (p &lt; 0.05). The 3 groups showed similar rates of rod-related complications with no significant difference (p = 0.95). And inside each group, distribution of complications between pseudarthrosis with revision and rod fracture without revision was also similar (p = 0.99).Conclusion: The use of multiple rods across the PSO did not show a better outcome when compared to single rods in terms of incidence and types of mechanical complications. However, better postoperative coronal alignment and health-related quality of life scores in the multiple rods group could be seen demonstrating an improved functional outcome.<\/jats:p>","DOI":"10.14245\/ns.2142596.298","type":"journal-article","created":{"date-parts":[[2021,10,20]],"date-time":"2021-10-20T16:37:25Z","timestamp":1634747845000},"page":"816-823","update-policy":"https:\/\/doi.org\/10.14245\/crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Multiple-Rod
