MS-3108

A 28-year-old man presents to the emergency department with a wrist injury sustained from a fall. Upon examination, the physician notes tenderness in the anatomical snuffbox, as well as localized swelling and bruising. The physician suspects a fracture in one of the carpal bones and orders a series of plain x-rays to confirm the diagnosis. The physician is concerned about the potential consequences of leaving this fracture untreated due to its precarious blood supply.

Which blood supply could be compromised as a result of this injury?
