Abstract
Background: With the increasing prevalence of adult spinal deformity (ASD) in the aging population, the need for corrective surgery has surged, highlighting the importance of preventing mechanical complications (MC) such as junctional kyphosis/failure and rod breakage. The Roussouly classification, which categorizes natural variations in spinal posture, may hold predictive value in assessing the risk of these complications, as it guides the restoration of sagittal alignment based on a patient's preoperative spinal shape.
Methods: PubMed, Cochrane, and Google Scholar (pages 1-20) were searched through August 2024 to find articles comparing the incidence of mechanical complications between patients who were matched and mismatched to their ideal Roussouly shape after surgery for ASD. Extracted data consisted of the risk of mechanical complications, and the risk of reoperations.
Results: 10 retrospective studies were included in this meta-analysis, with 1454 patients divided into 2 groups, the first group matching Roussouly classification (716 patients, 49%) and the second unmatched (738 patients, 51%). A 5-times lower rate of mechanical complication (Odds-Ratio = 0.22; 95% CI: 0.12-0.41, p < 0.001) was found in the matched group at an average follow-up of 3.6 years. Furthermore, when examining specific mechanical complications, there were higher rates of both PJK (Odds-Ratio = 1.59; 95% CI: 1.07-2.38, p = 0.02) and rod breakages (Odds-Ratio = 1.75; 95% CI: 1.15-2.66, p = 0.01) in the unmatched group. However, no difference in the rate of reoperations was observed between the two groups (Odds-Ratio = 0.48; 95% CI: 0.18-1.28, p = 0.14).
Conclusion: Matching patients to their ideal Roussouly type in adult spinal deformity surgery significantly reduces mechanical complications making it a secure and efficient method. Future studies should compare the Roussouly classification to other alignment models to determine optimal alignment for ASD correction surgery.
期刊介绍：
"European Spine Journal" is a publication founded in response to the increasing trend toward specialization in spinal surgery and spinal pathology in general. The Journal is devoted to all spine related disciplines, including functional and surgical anatomy of the spine, biomechanics and pathophysiology, diagnostic procedures, and neurology, surgery and outcomes. The aim of "European Spine Journal" is to support the further development of highly innovative spine treatments including but not restricted to surgery and to provide an integrated and balanced view of diagnostic, research and treatment procedures as well as outcomes that will enhance effective collaboration among specialists worldwide. The “European Spine Journal” also participates in education by means of videos, interactive meetings and the endorsement of educative efforts.
Official publication of EUROSPINE, The Spine Society of Europe
