Vertebroplasty by using HA Block for osteoporptic spine fracture

Abstract

Transpedicular vertebroplasty using HA block was carried out for patients with osteoporotic spine fracture. Special tools were developed to correct the fracture and to insert HA block transpedicularly. Significant restoration of vertebral bodies was done by insertion of HA block. The mean correction loss was 14% two months postoperatively. Pain relief was clearly obtained. Extravertebral HA block leakage was observed in 7cases (16%), but did not lead to clinical complications. In addition, there was no pulmonary embolism or nerve damage. This method is effective for wedge compression fracture and flat-burst fracture with severe pain. It is important to construct a solid wall near the anterior cortex with the cancellous bone in the center of the body. It concluded that HA Block is safe material. This method is less invasive, and should be indicated for painful osteoporotic fracture.
