Distal Radius Fractures are the most common site of pediatric forearm fractures and generally occur as a result of a fall on an outstretched hand with the wrist extended. Diagnosis is made with radiographs of the wrist. Treatment is generally closed reduction and casting for the majority of fractures.
On the lateral view, there is a minimally displaced radial metaphysis, which could be mistaken for a buckle fracture. However on the AP view, it shows that both cortices are broken (i.e. it is a complete fracture).
Buckle fractures are most commonly caused by kids catching themselves with outstretched arms after falling. The force of the fall compresses their bone and causes buckle fractures. This is why most buckle fractures (impacted fractures) affect kids’ forearm bones (their radius and ulna).
A buckle fracture is an incomplete fracture of the shaft of a long bone characterized by bulging of the cortex; usually seen in children, frequently involving the distal radial metaphysis.
A buckle fracture of the distal radius is a partial break of the bone and is the most common fracture in children. Almost all children recover very well within four weeks with the aid of a removable splint for pain control and protection.
A distal radius buckle (torus) fracture causes one side of the bone to bend but does not actually break through the bone. It is an incomplete fracture that normally heals within 1 month. If an x-ray shows this type of fracture, a splint will be put on the arm to help keep the bone protected.
What is a buckle fracture of the distal radius? The radius and ulna are the two long bones of the forearm, extending from the elbow to the wrist. A buckle fracture can often happen in children because their bones are softer than the bones of an older adolescent or adult.
Depending on the degree of angulation, buckle and greenstick fractures can be managed with immobilization. In adults, distal radius fractures are the most common forearm fractures and...
Isolated radius fractures are acceptable, but ulna fractures are usually associated with a radius fracture or radial head dislocation. When both bones are involved, they often each have a different fracture type, a combination of complete, greenstick, buckle, or plastic bowing deformity.
Buckle fractures of the distal radius are common in children between 2 and 12 years of age. Buckle (torus) fractures occur when the bony cortex is compressed and bulges, without extension of the fracture into the cortex (Figure 1).
