Abstract
PURPOSE: To compare the operative implications between adolescent idiopathic scoliosis patients (10-18 years) and young adult idiopathic scoliosis (YAdIS) patients (19-30 years). METHODS: This was a retrospective study querying the SRS M&M database for AIS (10-18 years) and YAdIS (19-30 years) cases enrolled between 2009 and 2015. Demographic and surgical parameters (Lenke curve classification, preoperative curve magnitude, approach type, osteotomy type, estimated blood volume (EBV), levels of fusion and ASA scores) were evaluated and compared between groups. RESULTS: N = 690: AIS (n = 607) and YAdIS (n = 83). Lenke curve classification distributions in AIS and YAdIS cases were: main thoracic, 293 vs. 34; double thoracic, 42 vs. 5; double major, 159 vs. 15; triple major, 15 vs. 5; thoracolumbar, 85 vs. 17; and lumbar, 5 vs. 6, respectively. Patients with a coronal curve > 90° were significantly greater in YAdIS vs. AIS patients, p = 0.008. Anterior and combined surgery rates were significantly higher in YAdIS, p = 0.028. Two-staged surgeries were significantly higher for YAdIS cohort, p = 0.01. Osteotomy rate was similar between groups, p = 0.42, but proportion of 3-column osteotomies was significantly higher for YAdIS, p < 0.001. ASA (severe systemic disease and some functional limitation) score 3 patients' rate was higher in YAdIS cohort, p = 0.01. EBV was significantly higher in YAdIS, p = 0.01. Average number of levels of fusions between cohorts was not significant, p = 0.87. CONCLUSIONS: The operative implications observed with young adult idiopathic scoliosis patients may potentially result in more complex surgical procedures and operative-associated complications than their adolescent counterparts. Further studies are required and should include a larger number of cases, be prospective in nature and verifiable data. LEVEL OF EVIDENCE: II.
