Open Reduction and Internal Fixation of Proximal Humerus Fracture

Open reduction and internal fixation (ORIF) is a surgical technique employed in severe proximal humerus fractures to restore normal anatomy and improve range of motion and function. Most proximal humerus fractures are not displaced and can be treated by a supportive sling and early rehabilitation. However, if fracture fragments are 5 mm apart or the angle between the fragments is more than 45 degrees, they are considered displaced and will require surgical intervention such as open reduction and internal fixation.
