Which patient population is mostly affected by Monteggia's fractures?

Monteggia fractures are characterized by an ulnar shaft fracture combined with an associated fracture or dislocation of the radial head. This type of injury is predominantly seen in children, typically due to their unique patterns of bone growth and the mechanisms of injury they are more likely to experience.

In children, their bones are still developing, making them more susceptible to certain types of fractures caused by falls or accidents. The elastic nature of pediatric bones allows them to bend and break in ways that are different from adult bones, which is why Monteggia fractures are commonly identified in younger patients. The mechanism of injury often involves a fall on an outstretched hand, leading to this combination of ulnar and radial injuries.

While other age groups, such as adults or the elderly, can experience fractures, the specific concurrence of ulnar and radial injuries typical of Monteggia fractures is less frequently seen outside of the pediatric population.
