We treated two patients, a 41-year-old man, and a 52-year-old woman with bone metastasis of the proximal humerus. Diagnoses were metastasis of thyroid carcinoma and renal cell carcinoma. The method for reconstruction was replacement with a modular endoprosthesis (Kyocera limb salvage System: KLS System). The rotator cuff and deltoid muscle were attached to the prosthesis. The average follow-up period was 18.5 months. The mean International Society Of Limb Salvage (ISOLS) score was 63%. The pain score was good, but function was poor. There were no signs of loosening or radiolucent areas, but a proximal migration of the prosthesis was observed on plain radiographs. This seemed to contribute to subacromial impingement and limitation of shoulder range of motion (ROM). The titanium KLS System allowed the monitoring for recurrence of the tumor with magnetic resonance imaging (MRI). These cases illustrate the usefulness of prosthetic replacement for reconstruction in the proximal humerus with the salvage system, although it limited shoulder ROM.
