A retrospective multicenter cohort study. ⋯ The present multicenter study identified for the first time the incidence and risk factors for UPROR with minimum 2-year follow-up after primary definitive fusion surgery for pediatric spinal deformity with every etiology.Level of Evidence: 3.
-
A retrospective case series. ⋯ Our simulation of anterior implant impingement and subsequent adjustment of the degree of spinal correction was useful to prevent dislocation. However, this method did not prevent dislocation in some patients.Level of Evidence: 4.
-
Retrospective. ⋯ The findings in this study indicate that PCF LIV selection may play a significant role in the development of mechanical complications and need for revision surgery. T2 LIV selection demonstrated a significantly lower rate of mechanical failure and revision surgery. Postoperative PROs up to 36 months are needed to evaluate effect of LIV selection on PROs.Level of Evidence: 3.
-
A retrospective analysis of a single-center consecutive series of patients. ⋯ Use of high-quality CT associated with spinal navigation significantly improved accuracy of screw positioning in the cervico-thoracic region.Level of Evidence: 3.
-
A cross-sectional analysis using T1 slope (T1S) and C7 slope (C7S) in asymptomatic individuals. ⋯ The normative values and age-related changes in C7S and T1S were analyzed. Both the C7S and T1S angles increased with age. The C7S angle was strongly correlated with the T1S angle, suggesting that C7S can substitute T1S on radiographic images.Level of Evidence: 3.
