Ulna bowing fracture

Case contributed by Dr Jeremy Jones

Presentation

Fall from parents bed. Landed awkwardly on arm. Not using arm.

Patient Data

Age: 8 months
Gender: Female
X-ray

Normal appearances on the AP view. On the lateral view, there is excessive curvature to the ulna with bowing in the volar direction.

Case Discussion

An isolated bowing fracture of the ulna is not common. They usually accompany more significant injury to radius, e.g. transverse or greenstick fracture.

It is important to recognise that physiological bowing may occur. However, it does not usually occur in an isolated bone and there was a clear history of trauma and forearm tenderness.

Treatment (in the absence of a more significant injury) is similar to a buckle fracture with support in a removable splint.
