What is the most common neurological finding associated with a distal radius fracture?

The most common neurological finding associated with a distal radius fracture is decreased sensation over the thenar eminence. This area is primarily innervated by the median nerve, which is commonly affected in injuries associated with distal radius fractures due to its anatomical proximity to the wrist.

When a distal radius fracture occurs, especially if it's associated with an impact or fracture displacement, the median nerve can become compressed or irritated. This compression can lead to symptoms, including numbness or decreased sensation in the skin over the thenar eminence, which encompasses the base of the thumb. Therefore, decreased sensation in this area serves as a clinical indicator of potential median nerve involvement, making it a key consideration when evaluating a patient with a distal radius fracture.

Other findings like wrist drop or weakness in finger adduction are typically associated with other types of nerve injuries or fractures in different anatomical locations.
