Two samples of amputated extremities were included in this study. Case 1 is a 31‐year‐old female who underwent artificial prosthesis replacement in treatment of Grade II chondrosarcoma in 2009. Parts of the starting point of deltoid muscle and the ending point of pectoralis major muscle were excised, and the brachial artery, median nerve, musculocutaneous nerve, axillary nerve, and radial nerve were remained. Then, a humeral prosthesis was implanted, a monofilament polypropylene fiber mesh (Bard® Mesh 26 cm × 36 cm) was fixed to the capsule, and four rivets were placed around the shoulder cup to reconstruct the soft tissue. Recurrence was observed in October 2013, forequarter amputation was performed, and the specimen was stored at −20°C.
