Summary
This study presents a novel 3D-printed antibiotic-loaded bone cement spacer for treating bone defect infections after limb salvage surgery. The technique successfully resolved infection and enabled limb salvage in a pediatric osteosarcoma patient.
Area of Science:
- Orthopedic Surgery
- Biomaterials Engineering
- 3D Printing Technology
Background:
- Limb salvage surgery is standard for malignant bone tumors.
- Postoperative infection and bone defects pose significant treatment challenges.
- Simultaneous infection control and bone defect management are critical.
