【 摘 要 】

BackgroundRadiotherapy is widely used as an effective adjunctive treatment modality in conjunction with conservative surgery for breast cancer. Radiation-induced skeletal changes in the shoulder region have been reported in 1% to 3% of patients who have undergone this treatment modality. With treatment techniques improving life expectancy, there is an increasing number of patients undergoing shoulder arthroplasty surgery with a history of cancer radiation therapy. To our knowledge, there are no reports focusing on potential radiation-related pathologic fractures of the shoulder after shoulder arthroplasty.Case reportWe present a case of catastrophic failure of glenoid component fixation after reverse shoulder arthroplasty (RSA) in a patient with previous high-dose radiation to the breast and supraclavicular areas. In this patient, failure of ingrowth of the baseplate and incorporation of the glenoid bone graft lead to eventual component loosening and subsidence. In addition, insufficiency fractures of the...
