The Various Reconstruction with Hydroxyapatite Powder(Bonesource(R))

ABSTRACT

Necessity of more biocompatible bone graft material had brought due to the problems of autologous bone graft & synthetic bone substitute materials. Bonesource(R) is a new biomaterial which can be replaced by natural bone when it is implanted. We reviewed our experience with Bonesource(in various reconstruction of bone defect for wide application. From March 2000 to March 2002 at Seoul National University Hospital, we performed various 7 cases of operation with Bonesource(R). These cases were bony depression after mass excision, alveolar cleft, frontal and supraorbital rim fracture, orbital deformity, facial asymmetry, bone defect after cranioplasty, depressive scar. In all cases, results were satisfactory without migration, extrusion, resorption during the follow up period (average 14 months). In 1 case, wound healing was delayed due to redissolution of Bonesource(R) by seroma. This was resolved by drainage without significant loss of volume. Its biocompatibility, excellent bony adhesion(osseointegration) and tendency to be replaced by natural bone(osteoconduction) may make it widely used in plastic surgery. The result of long term follow up and practical technique handling this material effectively are needed to evaluate it further.
