In the context of a Smith fracture, which is characterized by a fracture of the distal radius with an associated volar angulation and dislocation of the distal fragment, the median nerve is commonly associated with this type of injury. The median nerve runs in close proximity to the distal radius, and if the fracture displaces or if swelling occurs around the fracture site, it can put pressure on the median nerve, leading to symptoms such as tingling, numbness, or weakness in the hand, particularly in the first three fingers.

Understanding the anatomy is critical: the median nerve passes through the carpal tunnel at the wrist and innervates many of the flexor muscles of the forearm and some muscles in the hand. Entrapment due to the fracture or subsequent edema can lead to carpal tunnel syndrome-like symptoms, which is why it is important to monitor for median nerve involvement following a distal radius fracture, including a Smith fracture.

The other nerves mentioned are either more distal or not typically affected in the context of a Smith fracture. The radial nerve, for instance, is generally at a greater risk of injury with a Colles fracture, while the ulnar nerve issues would typically relate more to injuries at the elbow or certain wrist positions.
