Minimally invasive spine (MIS) surgery in traumatic thoracolumbar fractures: A single-center experience.

Objective: Traumatic thoracolumbar fractures are common, and surgical fixation is a well-established treatment option, with the aim to achieve spinal stability and preserve neurological function. Pedicle screw fixation using a minimally invasive spine (MIS) surgical approach has emerged as an alternative approach for the treatment of thoracolumbar fractures. The aim of this study is to collect data regarding epidemiology, management, and outcomes of patients treated with MIS pedicle screw fixation for traumatic thoracolumbar fractures in our neurosurgical department. Materials and Methods: This was a retrospective cohort study including all patients who underwent MIS fixation from March 2013 to March 2017. Results: A total of 125 patients were included, 61 males and 64 females; the mean age was 59 years. The majority of injuries were from falls. In 48 cases, the fracture involved a thoracic vertebra and in 77 cases a lumbar vertebra. More than 10% of the patients presented with a neurological deficit on admission and 75% of those showed postoperative improvement in their neurology. The average length of hospital stay was 14 days. MIS fixation achieved a satisfactory regional sagittal angle (RSA) postoperatively in all patients. The vast majority of patients had no or mild postoperative pain and achieved a good functional outcome. Conclusions: MIS fixation is a safe surgical option with comparable outcomes to open surgery and a potential reduction in perioperative morbidity. MIS surgery achieves a rapid and significant improvement in pain score, functional outcome, Frankel Grade, and RSA. We expect that MIS fixation will become the predominant technique in the management of traumatic thoracolumbar fractures. [ABSTRACT FROM AUTHOR]
