Management of Spinal Deformities Caused by Osteoporotic Vertebral Fractures.

Osteoporosis and fragility play a significant role in the treatment and planning of patients with deformity secondary to osteoporotic vertebral fracture (OVF). The resulting deformity can present significant challenges for its management, both from a medical and surgical perspective. The need for a specific classification for these deformities, including the potential for the development of artificial intelligence and machine learning in predictive analysis, is emerging as a key point in the coming years.

Osteoporotic vertebral fractures localized in the lumbar area significantly impact sagittal alignment.

Unlabelled: Lumbar fractures and/or multiple fractures at the lumbar or thoracolumbar regions are risk factors for sagittal malalignment in patients older than 70 years old. Although patients with OVF show a huge capacity to compensate after the fractures, lumbar and TL lumbar fractures require closer monitoring.

Purpose: To assess the impact of osteoporotic vertebral fractures on the sagittal alignment of the elderly and identify risk factors for sagittal malalignment.

Anatomic trajectory for iliac screw placement adapts better to the morphological features of the pelvis of each individual than the S2 alar iliac screw: a radiological study.

Purpose: The iliac fixation (IF) through the S2 ala permits the minimization of implant prominence and tissue dissection. An alternative to this technique is the anatomic iliac screw fixation (AI), which considers the perpendicular axis to the narrowest width of the ileum and the width of the screw. The morphological accuracy of the iliac screw insertion of two low profile iliac fixation (IF) techniques is investigated in this study.
