Surgical Treatment for Bone Tumors with Interconnected Porous Calcium Hydroxyapatite Ceramics

Abstract

We evaluated the short-term clinical results of patients with bone tumors using interconnected porous calcium hydroxyapatite ceramics (IP-CHA). Since 2005, a total of 23 patients with bone tumors were treated at our department using IP-CHA. The study group included thirteen men and ten women with an average age of 29 years. The mean follow-up was fifteen months. All the patient were implanted with IP-CHA for bone defects after resection or curettage of bone tumors. Postoperative radiological assessment revealed that the mean period for the radiolucent area between the implanted IP-CHA and the surrounding cancellous bone to disappear was 2.6 months. There were no allergic complications or pain associated with IP-CHA. Although local recurrence of the tumor was seen in one case, no patient developed postoperative fracture or infection.
We concluded that IP-CHA is a useful and safe bone-graft substitute in surgery for bone tumors.
