ABSTRACT
PURPOSE:
Risks of Ponte osteotomies (POs) used for posterior spinal fusion (PSF) for Adolescent Idiopathic Scoliosis (AIS) are challenging to assess because of the rarity of complications. Using a national administrative claims database, we evaluated trends, costs and complications associated with PO used in PSF for AIS patients.METHODS:
Using ICD-9/CPT codes, we identified patients (ages 10-18) with AIS who underwent PSF (± PO) between 2007 and 2015 in the IBM® MarketScan® Commercial Databases. Costs and trends of POs were evaluated. Odds of neurological complications and readmissions within 90 days and reoperations within 90 days and 2 years were assessed.RESULTS:
We identified 8881 AIS patients who had undergone PSF, of which 8193 had 90-day follow-up and 4248 had 2-year follow-up. Overall, 28.8% had PO. Annual rate of POs increased from 17.3 to 35.2% from 2007 to 2015 (p < 0.001). Risk-adjusted multivariable logistic regression demonstrated no relationship between POs and neurologic complications (p = 0.543). POs were associated with higher odds for readmission (1.52 [1.21-1.91]; p < 0.001) and reoperation (2.03 [1.13-3.59]; p = 0.015) within 90 days, but there were no differences in the odds of reoperation within 2 years (p = 0.836). Median hospital costs were $15,854 (17.4%) higher for patients with POs (p < 0.001) and multivariable modeling demonstrated POs to be an independent predictor of increased costs (p < 0.001).CONCLUSION:
Annual rate of POs increased steadily from 2007 to 2015. POs were not associated with increased odds of neurological complications but had higher costs and higher rates of readmissions and reoperations within 90 days. By 2 years, differences in reoperation rate were not significant. LEVEL OF EVIDENCE III.Mots clés
