What is a common complication associated with a scaphoid fracture?

A common complication associated with a scaphoid fracture is avascular necrosis. The scaphoid bone has a unique blood supply, which is primarily from branches of the radial artery. When a scaphoid fracture occurs, particularly if it involves the waist of the bone, it can disrupt the blood flow to the proximal fragment. This compromised blood supply places the proximal portion of the scaphoid at risk for avascular necrosis, leading to bone cell death due to lack of nourishment.

The risk of avascular necrosis is significant, as it can lead to subsequent complications such as nonunion or arthritis in the wrist, particularly if the fracture is not identified and immobilized early. Recognizing the potential for this complication emphasizes the importance of thorough evaluation and appropriate treatment for suspected scaphoid fractures, including the consideration of imaging studies like MRI or CT if the diagnosis is in doubt. Understanding this risk helps guide both the management of the fracture and the monitoring for potential long-term complications.
