Traumatic thoracolumbar (TL) fractures are the most common vertebral fractures. Although a consensus on the preferred treatment is missing, percutaneous pedicle screw fixation (PPSF) has been progressively accepted as treatment option, since it is related to lower soft tissues surgical-injury and perioperative complications rate. This study aims to evaluate the long-term clinical-radiological outcomes after PPSF for TL fractures at a single tertiary academic hospital. ⋯ In our case series, PPSF for TL injuries demonstrated good long-term clinical-radiological outcomes, along with low complication and reoperation rates. Accordingly, PPSF could be considered as a valuable treatment option for neurologically intact patients with TL fractures. Additionally, in this cohort, number of fractures ≥ 2, Cobb angle ≥ 15° and sagittal index ≥ 21° were independent risk factors for implant failure.

Anterior lumbar spine arthrodesis has been increasingly prescribed. In order to obtain better exposure of the intervertebral discs, it is necessary to identify vascular structures depending on the level to be approached. Systematic ligation of the iliolumbar vein has been suggested for access to the L4-L5 level, which may be technically challenging. The goal of the present study was to determine a safe limit for separating the iliolumbar vein safely without the need for its ligation. ⋯ Systematic ligature is not necessary for accessing the anterior route to the L4-L5 level, leading to a reduction in the time of surgery and avoiding serious vascular injuries that can occur.
