Abstract

A 7-year-old spayed female Welsh corgi presented with a mass of the skull. The mass was diagnosed as multilobular bone tumor and surgically removed. To treat a large bone defect after the tumor removal, custom-made artificial bone fabricated by a 3-dimensional ink-jet printer was implanted in the defect. Follow-up computed tomography evaluation was performed for 4.3 years. The implant was well integrated with the skull and had covered the large bone defect during the follow-up period. Gradual degradation of the implant began 6 weeks after surgery. It provides an additional option for the treatment of large bone defect.

두개골에 종괴를 가진 7세 암컷 웰키코기가 내원하였다. 종괴는 다엽성 골종양으로 진단되었으며, 외과적으로 제거하었다. 종양 제거후 발생한 대형 골결손부를 치료하기 위해 3D 잉크젯 프린터로 제작한 커스텀 메이드 인공뼈를 결손부에 이식하였다. 이식후 4.3년동안 CT촬영을 통해 변화를 관찰하였다. 인공뼈는 관찰기간동안 주변 두개골과 성공적으로 유합되어 결손부를 수복하고 있었으며, 이식후 6개월부터 점차적인 인공뼈의 흡수상이 확인되었다. 커스텀 메이드 인공뼈가 대형 골결손부의 또 다른 치료방법으로서 사용될 수 있을 것이라 기대된다.
