Background
Proximal humerus fractures make up about 5% of all fractures, but are one of the most common fractures of the geriatric population and are commonly encountered in radiology clinical practice. Understanding the biomechanical and vascular anatomy of the proximal humerus and how these features impact orthopedic surgical decision-making is key to creating relevant high-yield reports for our colleagues.

Educational Goals / Teaching Points
Understand the epidemiology, anatomy, biomechanics and pathophysiology of proximal humerus fractures. Review common fracture patterns. Identify imaging features important for clinical and operative management, including risk factors for humeral head ischemia. Learn about various treatment options for proximal humerus fractures, and the indications associated with particular options. Identify common complications of proximal humerus fractures and surgical complications.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
The unique morphology and mechanics of the proximal humerus creates a challenge to the orthopedic surgeon when treating complex fractures. Orthopedic surgeons need to assess mechanical and biological factors affecting stability, function, and healing. Understanding anatomy and pathophysiology is crucial in describing proximal humerus fractures in a clinically meaningful way to our clinicians. We discuss relevant anatomy and discuss how certain fracture patterns may determine surgical management and/or predict complications such as humeral head ischemia. Additionally, we provide an overview of the biomechanics that contribute to proximal humerus fractures, which can help the radiologist in understanding certain fracture patterns and relevant treatment by fracture type.

Conclusion
Certain features of proximal humerus fractures are particularly important in determining clinical management, but may not be familar to or well understood by many radiologists. A review of relevant anatomy and contributing biomechanics, along with the various surgical options, will help radiologists both better understand and readily identify and report these key features.
