Which nerve can be compromised in a Smith's fracture?

In the context of a Smith's fracture, which is a specific type of distal radius fracture characterized by a fracture of the radius with the distal fragment displaced volarly (anteriorly), the median nerve is the structure most at risk for compromise. This is primarily due to the anatomical location of the median nerve as it travels through the forearm and wrist.

When a Smith's fracture occurs, swelling and hematoma formation can lead to increased pressure in the carpal tunnel, where the median nerve runs alongside the flexor tendons. The position and nature of the fracture can also lead to bony fragments impinging on the nerve. Consequently, patients may present with symptoms of median nerve dysfunction, such as pain, tingling, or numbness in the thumb, index, middle finger, and part of the ring finger, as well as weakness in the thumb opposition.

The ulnar nerve, axillary nerve, and radial nerve do have their respective anatomical pathways and roles, but they are less likely to be affected by a Smith's fracture. The ulnar nerve primarily innervates the little finger and part of the ring finger and is more associated with injuries to the elbow or areas of the wrist where it is more superficial. The axillary
