2.2.1. Percutaneous Kyphoplasty (PKP)

After general anesthesia, the patient was placed in the prone position, with pillows under the chest and waist to maintain the hyperextension position. The injured vertebrae were confirmed by taking anteroposterior and lateral images by the C-arm. Then, bilateral transpedicular working channels were inserted by the cannula and trocar systems. After that, bilateral balloons were placed into the intravertebral vacuum cleft below the superior endplate. The balloon was carefully inflated to elevate the superior endplate, achieving height restoration and kyphosis correction. Polymethylmethacrylate (PMMA) bone cement was slowly injected to the point where balloon inflated, and the cavity was filled. All steps were performed under the guidance of the C-arm.
