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

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