Proximal humerus fractures are fairly common, with overall incidence being 4-5% of all fractures. Displaced four-part proximal humerus fractures often pose challenges before the surgeon especially in the elderly. Depending on the mechanism of injury and bone density at the time of injury, fracture patterns vary. In the older population, these fractures occur often in association with osteoporosis, preexisting rotator cuff pathology, and other comorbidities. These fractures are associated with a risk of avascular necrosis of the humeral head, with an incidence ranging from 21% to 75%. Shoulder hemiarthroplasty and, reverse total shoulder arthroplasty (RTSA) are indicated for complex fractures with high complication rates following head preserving procedures. The present study aims to assess the functional outcome of shoulder hemiarthroplasty in patients diagnosed with four part fracture and four part fracture dislocation admitted in Orthopaedic Department of IMS & SUM Hospital, Bhubaneswar in terms of pain, shoulder stability and range of movements at shoulder joint.
