In clinical practice, arm fractures can be diagnosed as ulnar radius fractures and humeral stem fractures. There is no clear clinical uniformity in the specific cost of treatment after a patient has suffered a fracture of the arm. This is because the cost varies with different treatment methods. If a patient has an ulnar radius fracture and is treated conservatively with manipulation under local anesthesia and external fixation with a plaster rest, small splint, and brace after repositioning, the cost of treatment is around $8,000-10,000. If the same fracture of the ulnar radius occurs and the fracture end is displaced, surgical treatment will be performed with incision and internal fixation of the plate, and the treatment cost will be about 20,000-22,000 dollars. In addition, if a humeral stem fracture occurs, surgical treatment with conventional incision and internal fixation with locking intramedullary pins will cost around $28,000-30,000.
