概要	Introduction:Due to the increase in osteoporosis accompanying the aging society in Japan, osteoporotic vertebral fractures (OVFs) are increasing. Percutaneous vertebral augmentation (PVA) has been widely used for OVFs because it reduces pain immediately with less invasiveness. Re-collapse of vertebral body after PVA is a rare, but important, complication. Once the re-collapse has occurred, patients should undergo an additional invasive salvage surgery.Methods:We treated 5 patients with re-collapse after PVA in our hospital. For re-collapse after PVA, we performed anterior column reconstruction with video-assisted thoracoscopic surgery (VATS), posterior fixation with percutaneous pedicle screws (PPSs) and minimally invasive spine stabilization (MISt).Results:The mean postoperative follow-up was at 62.8 months. At the final follow-up, the patients were free of low back pain, and bony union was achieved in all cases. The postoperative correction loss was 6 degrees. Perioperative complications included aspiration pneumonia in one patient and bone fracture of an adjacent vertebral body in two patients. There were no reoperation cases.Conclusions:We perform minimally invasive combined anterior and posterior surgery with VATS for re-collapse after PVA. This procedure is useful in elderly patients with less reserve capacity.
