Greenstick fractures are commonly seen in which group of patients?

Greenstick fractures are commonly seen in pediatric patients due to the unique characteristics of their bones. Children's bones are more flexible and pliable compared to those of adults. This pliability allows for incomplete fractures, such as greenstick fractures, where one side of the bone bends and breaks while the other side remains intact. This type of fracture resembles the way a green twig breaks – hence the name "greenstick."

In contrast, the other groups mentioned—adults, geriatric patients, and pregnant women—experience different types of fractures due to variations in bone density and strength, making greenstick fractures less common in these populations. Adults typically experience complete fractures due to the increased rigidity of their bones, while geriatric patients may suffer from more brittle fractures due to osteoporosis, and pregnant women are generally at risk for complications related to hormonal changes but not specifically for greenstick fractures.
