A scaphoid fracture, also known as a navicular fracture, is a break of one of the small bones in the wrist. Fracturing this bone is common, can occur in people of all ages, and has no specific risk factors. The main symptom is pain, though people often dismiss it as simple wrist fatigue. Treatments vary based on the type of fracture and how the fragments align; if left untreated, a scaphoid fracture can result in complications.
Your wrist is made up of the two main bones of the forearm -- the ulna and the radius -- as well as eight small carpal bones. Those eight bones align in two rows of four at the base of your hand. The scaphoid bone is the small carpal bone located at the base of the thumb and just above the radius. It is responsible for stability and plays a part in wrist motion.
