  • Innovative technique for early-onset scoliosis casting using Jackson table. Spine deformity Montgomery, B. K., Tileston, K., Kaur, J., Kym, D., Segovia, N. A., Imrie, M., Policy, J., Rinsky, L., Vorhies, J. 2022

    Abstract

    PURPOSE: Early-onset scoliosis (EOS) can have harmful effects on pulmonary function. Serial elongation, derotation, and flexion (EDF) casting can cure EOS or delay surgical intervention. Most described casting techniques call for specialized tables, which are not available at many institutions. We describe an innovative technique for EDF casting utilizing a modified Jackson table (MJ) and compare results to a Risser frame (RF).METHODS: All patients who underwent EDF casting at our institution between January 2015 and January 2019 were identified and retrospectively reviewed. Patients were stratified by type of table used and clinical and radiographic outcomes were compared. Standard descriptive statistics were calculated.RESULTS: We identified 25 patients who underwent 77 casting events, 11 on an MJ table and 14 on a RF. Mean follow-up was 32months (range 11-61months). 28% of patients had idiopathic scoliosis. There was no significant difference in age at initiation of casting (P=0.3), initial Cobb angle (equivalence, P=0.009), or rate of idiopathic scoliosis between the MJ and RF groups. There was no significant difference in initial coronal Cobb angle percent correction (equivalence, P=0.045) or percent correction at 1-year follow-up (equivalence, P=0.010) between the two groups. There was no difference in cast related complications. There was a significant difference in surgical time, with the MJ group 11min shorter than the RF (P=0.005).CONCLUSION: The MJ table is a safe and effective alternative for applying EDF casts under traction without the need for a specialized table.LEVEL OF EVIDENCE: III.
