Article Synopsis
- The choice of the lower vertebra for spinal fixation in adult spinal deformity, particularly around the lumbosacral junction, is debated, with options including stopping fixation at S1 or using lower points like S2AI or iliac screws to prevent implant pullout.
- A new technique for posterior fixation combines S1 screws, iliac screws, and sacro-iliac implants, inspired by triangular pelvic fixation methods used for trauma.
- This study outlines the operative technique using fluoroscopic guidance and shares preliminary results from treating 15 patients, labeled as level IV evidence.
Study Design: Cross-sectional Cohort Study.
Objective: To determine the cervicothoracic inflection point in an asymptomatic, adult population.
Introduction: The cervicothoracic inflection point (CTIP) is an important sagittal marker to understand for patients with cervical deformities.
The detection of noble gas radioisotopes following a suspected underground nuclear explosion is the surest indicator that nuclear detonation has occurred. However, the accurate interpretation and attribution of radioisotopic signatures is only possible with a complete understanding of transport processes occurring between the nuclear cavity and surface. In the far-field, diffusive forces contributing to gas transport are impacted by temperature gradients and subsurface lithology.

Objective: To classify spinal morphology using the "current" and "theoretical" Roussouly systems and assess sagittal alignment in an asymptomatic cohort.
Methods: 467 asymptomatic volunteers were recruited from 5 countries.
Study Design: Multi-Ethnic Alignment Normative Study (MEANS) cohort: prospective, cross-sectional, multicenter.
Objective: To analyze the distribution of GAP scores in the MEANS cohort and compare the spinal shape via stratification by GAP alignment category, age, and country.
Summary Of Background Data: The GAP score has been used to categorize spinal morphology and prognosticate adult spinal deformity surgical outcomes and mechanical complications.
