Retrospective cohort study. ⋯ All of the evaluated PROMIS domains (Pain Interference, Mobility, Physical Stress Experiences, Psychological Stress Experiences, Physical Activity) were reliably translated directly from these legacy scores for pediatric and adolescent patients with spinal deformity.Level of Evidence: 3.
-
Retrospective case-control study. ⋯ The MIS-ATP technique results in a high fusion rate (96.4% of patients; 98.3% of levels). Pseudarthrosis was noted mostly at the L5-S1 discs and in smokers.Level of Evidence: 4.
-
A retrospective study. ⋯ Through our study, the risk factors of Post sagittal imbalance were the Post value of PI-LL and that of PTr, and target value of PI-LL was <1.33 and that of PTr was <25.95%. These target values can be effective guidelines for spine surgeons who perform spine reconstruction surgeries for elderly patients with a pure sagittal imbalance based on Schwab's formula.Level of Evidence: 4.

A cross-sectional study. ⋯ The thecal sac area was reduced in older age group from T12/L1 to L4/5, and the thecal sac area was reduced in the anteroposterior and all directions in the upper and lower lumbar area in age group, respectively. Approximately, 3.0% of healthy population in their 50s or older will have severe asymptomatic stenosis.Level of Evidence: 2.
