A torus fracture, also commonly known as a buckle fracture is one of the most common injuries seen in children. Kids bones are much softer and flexible making them more susceptible to this type of break than any other age group. In this type of break, one side of the bone will fracture while leaving the other side of the bone without disruption. This is also known as an incomplete fracture when seen in teens or adults. Children suffer from two main forms of incomplete bone fractures.
Greenstick fractures are a form of tension injury. These occur when one part of the bone is pulled too far to one side. A buckle fracture is a compression injury that occurs when a part of the bone is compressed on one side. This compression causes a crumpling type effect on a single side of the bone. Only children are able to develop buckle fractures.
When too much force is applied to a bone, it will result in it being broken. Buckle fractures have a wide range of causes, but they result in one side of the bone being broken while the other remains intact. In most cases with a buckle fracture, the nerves, blood vessels, joints and muscles in the surrounding area are also affected. The damage to the surrounding areas can cause tenderness and pain.
Damage to the soft tissue can cause visible bruising. The bruised areas will be tender to the touch. If there is swelling, that can increase the tenderness around the injured area. The bones in your body are also surrounded by nerve endings. These nerves get irritated when a bone breaks and can cause tenderness until the wound heals.
Buckle fractures are known to be tender to the touch, in some cases touching the limb that is injured can cause extreme pain.
