Treatment of Humeral Fracture after Shoulder Arthroplasty using Functional Brace: A Case Report.

INTRODUCTION: A periprosthetic humeral fracture is rare after shoulder arthroplasty, and such cases have considerable problems. Patients with this kind of fracture are often complicated by osteopenia, other types of severe disease, or are elderly. Surgical treatment of this fracture type carries some risk, and surgeons may be unsure about the most appropriate approach to adopt.

CASE REPORT: The present case occurred in a 78-year-old woman with an osteoporotic humeral bone, and chronic dislocation of shoulder after shoulder arthroplasty. There were many risk factors for revision surgery or ostheosynthesis. Therefore, we decided to treat the patient by functional bracing. Fortunately, complete radiographic union was confirmed at 17 weeks. She returned to daily life with good functional activity.

CONCLUSION: In our opinion, it is acceptable to select functional bracing for periprosthetic humeral fractures after shoulder arthroplasty without stem loosening in elderly patients with an osteoporotic humeral bone.
