Résumé
Aseptic loosening is considered to be a rather uncommon complication in proximal humerus endoprosthetic replacement (PHER). However, patients with aseptic loosening often suffer severe bone loss, which poses a great challenge in following revision. Under this situation, a standard stemmed endoprosthesis is unavailable for revision limb salvage. Computer-aided design and 3D-printed personalized implants are an emerging solution for reconstructing complex bone defects. Here, we present a 67-year-old male who underwent PHER after tumor resection and developed aseptic loosening with severe periprosthetic osteolysis around the stem. Computer-aided design and 3D-printed personalized stem-plate composite was used for the precision revision of this patient. During the follow-up, encouraging results were observed, with good endoprosthetic stability and satisfactory limb function. 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.

METHODS
Here, we present a 67-year-old male who underwent PHER after tumor resection and developed aseptic loosening with severe periprosthetic osteolysis around the stem. Computer-aided design and 3D-printed personalized stem-plate composite was used for the precision revision of this patient.

CONCLUSIONS
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.
