Computer-aided Design and 3D-printed Personalized Stem-plate Composite for Precision Revision of the Proximal Humerus Endoprosthetic Replacement: A Technique Note.

Computer-aid design and 3D-printed personalized stem-plate composite used in the present case could help to achieve good endoprosthetic stability and satisfactory limb function. This 3D-printed personalized stem-plate composite seems to be an effective method for the precise revision of PHER in patients with severe periprosthetic osteolysis. In addition, it also provides a novel method for similar revision surgery of other joints or primary endoprosthetic replacement with severe bone defects.
