To validate a fast 3D biplanar spinal radiograph reconstruction method with automatic extract curvature parameters using artificial intelligence (AI). ⋯ The developed AI algorithm could reconstruct a 3D scoliotic spine within 6 s, and the automatic curvature parameters were accurately and reliably extracted from the reconstructed images.

In this longitudinal cohort study, we investigated the relationship of disc degeneration (DD) after pubertal growth spurt to future low back pain (LBP). ⋯ This is the first study to suggest that DD may be associated with future LBP and the critical time frame seems to be the pubertal growth spurt. Every 1-point increase in Pfirrmann grade at age 18 increased the risk of LBP 5.5-fold at age 34 when adjusted for sex, BMI, smoking and physical activity at age 34. All participants but one with at least one disc with Pfirrmann grade 3 or higher at age 18 reported LBP at age 34.

Subsequent vertebral fracture (SVF) is a severe advent event of percutaneous vertebral augmentation (PVA). However, the incidence and risk factors of SVF following PVA for OVCF in postmenopausal women remain unclear. This research aims to investigative the incidence and risk factors of SVF after PVA for OVCF in postmenopausal women. ⋯ The incidence of SVF following PVA for OVCF in postmenopausal women was 14.66%. BMI, steroid use, history of previous vertebral fracture, postoperative wedge angle, and HU value were independent risk factors of SVF after PVA for OVCF in postmenopausal women.

Postoperative infection after spinal deformity correction in pediatric patients is associated with significant costs. Identifying risk factors associated with postoperative infection would help surgeons identify high-risk patients that may require interventions to minimize infection risk. ⋯ To our knowledge, this is the largest study of risk factors for infection in pediatric spinal deformity surgery. We found 5 patient factors (BMI, ASA, osteotomy, etiology, and previous surgery, and 3 surgeon-controlled factors (surgical time, antibiotics, MIS) associated with risk. The Pediatric Scoliosis Infection Risk Score (PSIR) Score can be applied for risk stratification and to investigate implementation of novel protocols to reduce infection rates in high-risk patients.

The goal of this study was to explore sex-related variations of global alignment parameters and their distinct evolution patterns across age groups. ⋯ Males present more anteriorly tilted spine with age mainly explained by a PI increase in females between Young and Middle-Aged, which may be attributed to childbirth. Consequently, SS and LL increased before decreasing at senior age.
