Objective To explore the clinical effectiveness and safety of percutaneous vertebral augmentation with the Vessel-X bone void filling container system (Vesselplasty). Methods Three cases of fresh osteoporotic vertebral compression fracture were treated with Vesselplasty. After procedure, the pain relief, the fracture reduction, and the cement distribution in the vertebra were observed. Results All the 3 cases were treated with the unipediclar injection technique. The operative time was 45, 32 and 30 min, respectively. The hemorrhage volume was 5 ml. The cement volume injected was 3.5, 2.7, and 2.9 ml per vertebra, respectively. A significant pain relief was observed in all the 3 cases. The anterior vertebral height was recovered from 19.5, 14.3, and 20.7 mm preoperatively to 22.5, 18.5, and 21.4 mm postoperatively. The midline vertebral height was recovered from 13.7, 13.9 and 18.6 mm preoperatively to 17.4, 17.9, and 20.7 mm postoperatively. The distribution of cement in the vertebra was seen as irregular oblong configuration without any leakage out of the vertebra. Follow-up observations in the 3 cases for 12, 17, and 18 months, respectively, showed sustained pain relief. Conclusions Vesselplasty shows ability to limit the cement distribution in the vertebra and diminish the cement leakage. It is an effective alternative to balloon kyphoplasty.
