Objective:
The aim of this study is to introduce surgical technique of endoscopic decompression combined with percutaneous pedicle screw fixation (PPSF) for thoracolumbar burst fractures (TLBFs) with neurological deficits and evaluate its efficacy.
Methods:
A total of 32 patients with TLBFs and neurological deficits who were treated by endoscopic decompression combined with PPSF from June 2018 to August 2019 were included in this study. The effect of decompression was analyzed using canal encroachment ratio, while deformity correction was assessed using the sagittal Cobb angle and the percentage of anterior vertebral height. We also analyzed other clinical outcomes such as visual analog scale, Oswestry Disability Index, and American Spinal Injury Association impairment scale dose.
Results:
The patients were followed up for an average of 16 months. Our data showed that the patients' mean operation time was 153.75 minutes, the mean intraoperative blood loss was 48.84 mL, and the mean incision length was 7.78 cm. The canal encroachment ratio decreased from 55.91% ± 12.27% to 12.44% ± 3.91% (P < 0.05), sagittal Cobb angle decreased from 17.09° ± 5.46° to 5.72° ± 3.68° (P < 0.05), while the percentage of anterior vertebral height increased from 53.72% ± 8.99% to 83.22% ± 8.21% (P < 0.05). In addition, there was a significant improvement in the visual analog scale score, Oswestry Disability Index, and American Spinal Injury Association impairment scale classification (P < 0.05). Screw fracture occurred only in one patient during follow-up.
Conclusions:
Endoscopic decompression combined with PPSF in the treatment of TLBFs with neurological deficits is safe and effective, which is a new minimally invasive method for the treatment of such diseases.
