Rationale:
Three-dimensional (3D) printing has been widely utilized for treating the tumors of bone and soft tissue. We herewith report a unique case of distal radial osteosarcoma who was treated with a 3D printed porous tantalum prosthesis.Patient concerns: A 58-year-old Chinese male patient presented to our clinic complaining about a 6-month history of a progressive pain at his right hand, associated with a growing lump 2 months later.
Diagnosis:
Osteosarcoma of distal radius confirmed by percutaneous biopsy and tumor biopsy.
Interventions:
A limb-salvage surgery was performed with a 3D printed porous tantalum prosthesis, combined with the postoperative chemotherapy for 4 cycles.
Outcomes:
At 2-year follow-up, complete pain relief and satisfactory functional recovery of his right wrist were observed.
Lessons:
Personalized 3D printed prosthesis is an effective and feasible method for treating the osteosarcoma and reconstruction of complex bone defects.
