Cirugía mínimamente invasiva en el tratamiento de fracturas tóracolumbares

Abstract

Objective: To analyze and describe a series of trauma-related thoraco-lumbo-sacral vertebral fractures managed with minimally invasive surgery.
Methods: We retrospectively review the charts and images of 26 patients with thoracolumbar spine fractures between 2010-2017. Pre-op images were assessed and fractures were classified according to the thoraco-lumbar trauma AO Spine classification. We analyzed pre and post-surgical visual analog scale (VAS), blood loss during surgery, hospital length of stay, complications, associated surgical procedures, long term post-op implant removal, pre and post neurological status and mortality.
Patients with a complete case record, pre-op CT scans and minimum 12-month follow up were included (18 males and 8 females). Mean age was 28.7 years (21-84 years); mean post-op follow up was 28 month (13-86 months). Eighteen patients were managed with percutaneous instrumentation, 8 patients also received percutaneous vertebroplasty, and 5 patients underwent also some arthrodesis procedure.
Results: VAS improved 7 points as compared to the pre-op score; mean blood loss was 40 mL, we did not observed any neurological deficit worsening. Mean hospital length of stay was 3.9 days. Four patients needed surgical procedures involving other organs due to politrauma.
Percutaneous screws were removed in 9 cases after fracture consolidation. Complications were: one case of self-limiting retroperitoneal hematoma, one case of pedicle screw fracture and one cement broken cannula into the pedicle.
Conclusion: Minimally invasive surgery in spine trauma is a valid option allowing stabilization, early mobilization, and leading to good outcomes in terms of pain control and a lower complication rate.
