Spinopelvic sagittal balance: what does the radiologist need to know?
Savarese,Leonor Garbin; Menezes-Reis,Rafael; Bonugli,Gustavo Perazzoli; Herrero,Carlos Fernando Pereira da Silva; Defino,Helton Luiz AparecidoSagittal balance describes the optimal alignment of the spine in the sagittal plane, resulting from the interaction between the spine and lower limbs, via the pelvis. Understanding sagittal balance has gained importance, especially in the last decade, because sagittal imbalance correlates directly with disability and pain. Diseases that alter that balance cause sagittal malalignment and may trigger compensatory...

THE SEVERAL FACES OF SCHMORL'S NODE: PICTORIAL ESSAY
Nogueira-Barbosa,Marcello Henrique; Crema,Michel Daoud; Herrero,Carlos Fernando Pereira da Silva; Pasqualini,Wagner; Defino,Helton Luiz AparecidoThe aim of this review is to present the imaging features of Schmorl's node (SN) occurring in conjunction with several etiologies. The SN is a relatively common finding in diagnostic spinal imaging. This condition is usually asymptomatic and its etiology is not always clear. Any disorder that weakens the subchondral bone of the vertebral body may lead to endplate disruption and consequent intravertebral disc he...
