Cement Spacer Formed in a 3D-Printed Mold for Endoprosthetic Reconstruction of an Infected Sarcomatous Radius: A Case Report.

ABSTRACT

CASE The ulcerated recurrent clear cell sarcoma of the forearm with bony invasion of the radius needed an uncontaminated resection and control of infection. A mold was printed based on CT-reconstructed 3D models of the patient's anatomy to create an antibiotic-loaded cement spacer as endoprosthetic replacement used in combination with soft-tissue reconstruction and systemic antibiotics. CONCLUSION: This then undescribed novel technique allowed for fast local recovery of the patient's hand function and return to work. In selected cases, such an anatomically formed spacer may be preferred for faster functional recovery and longer intervals before definitive reconstruction is possible.
