ABSTRACT
<p><b>OBJECTIVE</b>To study a new implant material (carbonated hydroxyapatite, CHA) united pedicle screw to cure spine fracture.</p><p><b>METHODS</b>Thirty-two cases of spine compressed fracture were used with pedicle screw fixator and vertebroplasty. Before operation, patients' vertebral body were compressed (46 + 21)% (20% approximately 70%) on average. In operation, broken vertebral body was reposition through pedicle screw technique, then used self-made syringe to inject CHA into anterior and central column of broken vertebral body through pedicle. And all of patients were not given any bone-graft.</p><p><b>RESULTS</b>In 6 - 26 months followed-up, no immunologic rejection was found about hydroxyapatite, and no any broken of the screws and shafts was found, no loosing and other complications either. All the patients could move in 3 - 5 days after operation. The height of the broken vertebral body were reduced 97% compared with pre-operation. And CHA in vertebral body was degraded gradually, and at the same time it was replace by new bone in vertebral body. After operation, VAS score was 61 +/- 32, and there was significant difference compared with pre-operation.</p><p><b>CONCLUSIONS</b>The pedicle screw fixation united vertebroplasty is an efficient way to prevent the failure of the treatment of spine fracture.</p>
