Flexion fracture

A flexion fracture is a type of isolated fracture of the humerus. With this injury, the head of this bone is displaced relative to the glenoid cavity of the head of the radius and, as a result of the forward movement of the shoulder, the integrity of the articular surfaces of this joint is disrupted. In addition, at a later date, nonunion of the proximal metaepiphysis may be associated with the fracture. In most cases, fractures of this type occur in people of middle age, as well as in the elderly. It is also possible that segments of the humerus may be damaged in childhood.

The causes of injury are flexion and extension. The source of the traumatic agent is its peculiar height, that is, a force that can damage a section of the articular surface of the contacting joints. Injuries of this type account for approximately 21
