Abstract
OBJECTIVE: This study was performed to describe a new minimally invasive surgical technique and to explore its effects and practical use in the clinical setting. METHODS: In total, 22 patients with single-segment thoracolumbar burst fractures underwent treatment with an intelligently inflatable reduction device before common percutaneous pedicle screw fixation. Complications were recorded and short-term effectiveness was evaluated using the visual analogue scale (VAS) score for pain, Oswestry Disability Index (ODI), kyphotic Cobb angle, and anterior edge height of the fractured vertebra preoperatively and postoperatively. RESULTS: The patients were followed up from 2 to 5 years. The differences in the VAS score and ODI reached statistical significance at different time points. Similar significant differences were observed in the kyphotic Cobb angle and the vertebral body anterior height except between the two postoperative measurements. CONCLUSIONS: The current study indicated that use of the intelligently inflatable reduction device with conventional percutaneous pedicle screw fixation can improve the reduction and healing of single-segment thoracolumbar burst fractures in adult patients. This technique induces minimal trauma, provides reliable fixation, and has few complications.
