Hemiarthroplasty for Elderly With Proximal Humeral Mets

Bone metastases are common in patients with advanced cancer and frequently involve the proximal humerus, leading to severe pain and loss of shoulder function. Shoulder arthroplasty is an important surgical option for restoring limb function and relieving pain in these patients. However, elderly patients often have multiple comorbidities, and it remains unclear whether age affects surgical outcomes and prognosis after arthroplasty for proximal humeral metastases. This retrospective observational study reviewed patients with isolated proximal humeral metastases who underwent shoulder arthroplasty at our institution. Patients were divided into elderly and younger groups based on age, and clinical outcomes were compared between the groups. Evaluated outcomes included operative characteristics, postoperative pain, limb function, complications, survival, recurrence, and quality of life. The aim of this study is to determine whether age influences prognosis and functional recovery after shoulder arthroplasty for proximal humeral metastases, and to assess the feasibility and effectiveness of this surgical procedure in elderly patients.
