In the event of a blow to the wrist (e.g falling on an outstretched hand), the scaphoid takes most of the force. If localized pain is reported in the anatomical snuffbox, just think SCAPHOID FRACTURE! ⁣⁣⁣ ⁣⁣⁣ The scaphoid has a unique blood supply, which runs distal to proximal. A fracture of the scaphoid can disrupt the blood supply to the proximal portion – this is an emergency. Failure to revascularize the scaphoid can lead to avascular necrosis, and experience of future athritis⁣⁣⁣ ⁣ Stay tuned for special videos in Anatomy on our YouTube channel, link in bio! ⁣
