A retrospective case-series of adolescent idiopathic scoliosis patients with 5 to 15 years follow-up after segmental pedicle screw instrumentation.

The frequency of complications was 12.5%.

Mean curve correction was 78% immediately preoperative with a 4° increase at last follow-up.

SRS-22 total/self-image and the EQ-5D utility scores were significantly improved at last follow-up.

Socioeconomic factors, Lenke type 2, number of levels instrumented and curve correction were important predictors for satisfaction in a logistic regression model (AUC 85%).
