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.
-
A retrospective comparative study with radiographic measurements. ⋯ PSAs played an important role in FASV. MIS allowed greater PSAs and resulted in fewer incidences of FASV. To avoid FASV in 90% of patients, the PSAs might be at least 11.9° and 15.9° at L4 level, and 15.9° and 21.8° at L5 level for OS and MIS techniques, respectively.Level of Evidence: 3.
-
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 laboratory study performed in a self-controlled fashion. ⋯ "Surgical smoke" generated by electrocauterization of porcine spinal tissues contains viable bacteria. Further research in actual spine surgery is needed next.Level of Evidence: N/A.
