New endoprosthesis suspension method with polypropylene monofilament knitted mesh after resection of bone tumors in proximal humerus

摘要

Background: Endoprosthetic reconstruction of the proximal humerus is one of the standard procedures after resection of tumors of the proximal humerus and has been considered a reliable method to reconstruct the proximal humerus in recent reports. However, instability of the shoulder joint caused by loss of the rotator cuff and deltoid muscle function is often observed after such an endoprosthetic reconstruction.
