A Study on Functional Outcome of Hemiarthroplasty for Proximal Humeral Fractures - An Observational Study.

Introduction: Proximal humeral fractures (PHFs) represent a significant portion of fragility fractures in the elderly, ranking third after hip and distal radius fractures. While the majority of minimally displaced PHFs can be managed nonoperatively, displaced three- and four-part fractures often require surgical intervention. Hemiarthroplasty (HA) has traditionally been used for complex fracture patterns. With recent advances in prosthetic design and surgical techniques, HA continues to be a valuable option. Case Series: This case series evaluated patients with Proximal humeral fractures, This study aims to assess the functional outcomes of three- or four-part proximal humerus fractures treated with hemiarthroplasty using Constant and UCLA scores. Additionally, it evaluates radiological parameters such as tuberosity position and union, tuberosity resorption, humeral head height, and signs of implant loosening or radiolucency at the bone-cement interface through serial shoulder radiographs. Conclusion: Hemiarthroplasty provides reliable pain relief and functional recovery in elderly patients with complex proximal humerus fractures. It shows low complication rates and high patient satisfaction, though larger studies with long-term follow-up are needed for broader validation.
