The Humelock Hemiarthoplasty Device for Both Primary and Failed Management of Proximal Humerus Fractures: A Case Series

Fractures of the proximal humerus account for 4-5% of all fractures. Managing proximal humerus fractures operatively and non-operatively have their respective complications both short- and long-term. We present our experience using the Humelock hemiarthoplasty device for both primary and failed management of proximal humeral fractures. We present four different examples from ten cases that include a failure of internal fixation, a failure of intramedullary nailing, a complex case in a patient with multiple co-morbidities, and a failure of nonoperative management. The patients in our series had multiple injuries and the device allowed early mobilization and produced good results. We suggest that this device has a role in the failure of primary and secondary management of proximal humeral fractures in a district general hospital setting.
