Torus fracture of the radius

Case contributed by Leonardo Lustosa

Presentation

Forearm pain after falling onto the outstretched hand.

Patient Data

Age: 13 years
Gender: Male

Before closed reduction

X-ray

There is a bulging of the cortex of the distal metaphysis of the radius. The lateral radiograph reveals a volar angulation component to the fracture on the sagittal plane.

After closed reduction

X-ray

Follow-up radiographs after closed reduction. The volar displacement has been reduced.

Case Discussion

Torus fractures, also known as buckle fractures, are incomplete fractures of the shaft of long bones, usually occurring on immature skeletons.

Acceptable residual angulation after closed reduction depends on age. In the present case, the boy was 13 years old, to which the usual acceptable angulation on the sagittal plane ranges from 5-10º depending on skeletal maturity (the more mature the skeleton the less acceptable a greater sagittal angulation).
