Introduction:
Proximal humerus fractures are one of the most common fractures in the elderly population and ranked third among the incidence of the fragility fractures. They most commonly occur in patients over 60 years of age following a low-energy domestic fall. Neer's classification is the most common classification system of proximal humerus fractures. It is based on six groups and four main fracture segments comprising the head, greater tuberosity, lesser tuberosity and shaft. The diagnosis is confirmed using plain radiographs and computerized tomography (CT) scan with 3- dimension reconstruction. There is no consensus on the method of choice for treating displaced 3- and 4-part proximal humerus fractures in the elderly. Decision making should be tailored and individualized according to the patient age, medical co-morbidities, functional demands and expectations. Non operative management, open reduction internal fixation and arthroplasty are the treatment options.

Aim of the work:
To compare the radiological and functional outcome between open reduction internal fixation (ORIF) using locked plates and non-operative treatment of displaced three- and four-part proximal humerus fractures in the elderly population.
