A detailed neurovascular exam is essential because defi- cits can help pinpoint specific injuries. A widened radioulnar joint suggests disruption of this complex and subluxations at the wrist or elbow must be carefully noted. The lateral projection of the distal radius usually demonstrates a volar tilt of 10-25 degrees. Diagnosis, Treatment, Disposition and Complications Diagnosis of forearm injuries in usually straightforward and based on the physi- cal and radiographic findings. Due to the relatively fixed nature of the ulna, exacting reduction is necessary to retain function. Orthopedic correction is needed for angu- lation of >10 degrees or displacement of >50% of the diameter of the bone. Radius fractures are considered displaced when angulation is >20 degrees or >1 cm of short- ening. Be sure to exclude epiphyseal injuries of the distal radius in children with wrist trauma because the carpal bones are cartilaginous and rarely injured.
