Greenstick fractures

Greenstick fracture is a type of bone fracture where one side of the bone is broken while the other side is only bent, resulting in the bone not being completely broken. This type of fracture is commonly observed in children due to the properties of their bones, which undergo large deformation but do not completely break. A greenstick fracture can be defined as a fracture where the bone breaks on one side and is bent on the other side.From: Medical Imaging [2019], Simulation of bone fractures via geometric techniques: an overview [2019], Bone Mechanics Handbook [2019], Mine Safety Science and Engineering [2019]

In a greenstick fracture, one side of the bone is broken, and the other only bent. The fracture line is perpendicular to the shaft in a transverse fracture, whereas the fracture line makes an angle with the bone in an oblique fracture. A spiral fracture occurs when the body is in motion,and a rotating force is applied along the axis of a bone. An avulsed fracture occurs when a tendon or ligament pulls off a piece of the bone. A segmental fracture contains at least two fracture lines with several separate pieces. If the bone is broken into multiple pieces, possibly with dislocation, then the fracture is called comminuted [3]. All of the fracture types mentioned are shown in Figure 7.4.

In a greenstick fracture, the bone is not completely broken. Transverse, oblique and spiral fractures can be considered similar because they generate two fragments with similar features. Avulsed fractures normally occur near a joint, thus, the fracture zone is composed almost exclusively by trabecular tissue and the boundaries of the fragments are weak. Segmental fractures are simple fractures that generate three bone fragments. Therefore, they can be treated as transverse or oblique fractures. Comminuted fractures are usually caused by crush injuries. This kind of fracture is more complicated, it can generate small fragments and the bone can be deformed.
