Ten-year trends in surgical management of 1207 congenital scoliosis

Purpose To report and analyze development trends in the surgical treatment of congenital scoliosis (CS) in a large CS cohort over a 10-year period. Methods We retrospectively searched and extracted medical records of CS inpatients receiving posterior instrumented fusion surgery at our institute from January 2010 to December 2019. We analyzed information on demographics and surgical information, including the surgical approach, number of fused segments, use of osteotomy and titanium cage implantation, length of stay, intraoperative blood loss, and rates of complications and readmission. Results 1207 CS inpatients were included. In the past decade, the proportion of patients younger than 5 years increased from 15.5 to 26.9%. The average number of fused segments decreased from 9.24 to 7.48, and the proportion of patients treated with short-segment fusion increased from 13.4 to 30.3%. The proportion of patients treated with osteotomy and titanium cage implantation increased from 55.65% and 12.03% to 76.5% and 40.22%. The average length of stay and blood loss decreased from 16.5 days and 816.1 ml to 13.5 days and 501.7 ml. The complication and readmission rates also decreased during these ten years. Conclusion During this ten-year period, the surgical treatment of CS at our institute showed trends toward a younger age at fusion, lower number of fused segments, higher rate of osteotomy and titanium cage implantation, reduced blood loss, shorter length of stay and lower rate complications and readmission. These results suggest performing osteotomy combined with titanium cage implantation at an earlier age can achieve fewer fused segments and complications.
