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.
