Which nerve injuries are most commonly associated with forearm injuries?

• A. Axillary
• B. Median and Ulnar
• C. Peroneal
• D. Radial

Answer: (B)

Nerves that run through the forearm are the ones most at risk in forearm trauma. The median and ulnar nerves travel directly along the forearm within the flexor compartment, making them particularly vulnerable when the forearm is fractured or lacerated. Because of their long course and close relationship to the bones and tendons in this region, injuries to the forearm commonly produce motor and sensory deficits in these nerves’ distributions. The axillary nerve is associated with the shoulder, the peroneal nerve with the leg, and while the radial nerve can be injured in forearm trauma, the combination of the median and ulnar nerves is the classic pair most commonly affected by forearm injuries.
