How do you treat radial nerve injury with supracondylar fracture in children?

Radial Nerve: The presence of a wrist drop with a humeral fracture is most often due to a stretch injury or contusion of the nerve as it travels down the arm in the spiral groove. An extension wrist splint may be helpful to prevent a flexion contracture from the associated wrist drop. If there is an absence of improvement on exam and serial EMG testing, surgical exploration may need to be considered.

Waiting: Most nerve injuries related to supracondylar fractures recover with time and are related to stretch injuries at the time of injury.
