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

In the context of a Smith's fracture, which is a distal radius fracture that typically occurs due to a fall on a flexed wrist, the median nerve is particularly at risk. The median nerve runs in close proximity to the radius and can be affected by swelling or displacement associated with this type of fracture. Injury to the median nerve can lead to symptoms such as numbness or tingling in the thumb, index, middle finger, and part of the ring finger, as well as motor deficits affecting the thenar muscles.

Understanding the anatomy involved is crucial here. The radial nerve, while associated with upper limb function, typically does not directly relate to the complications seen in a Smith's fracture. Similarly, the ulnar nerve and axillary nerve do not have a direct connection to this specific injury, as they are located further from the fracture site and innervate different regions of the arm and hand. The focus on the median nerve emphasizes its anatomical position and its role in the clinical presentation following a Smith's fracture.
