What is scaphoid fracture?
A scaphoid (navicular) fracture is a break in one of the small bones of the wrist. This type of fracture occurs most often after a fall onto an outstretched hand. Symptoms of a scaphoid fracture typically include pain and tenderness in the area just below the base of the thumb.

How fast does avascular necrosis progress?
AVN has four stages that can progress over a period of several months to more than a year. In Stage I, the hip is healthy; in Stage II, the patient experiences mild pain in direct proportion to the deterioration of the head of the femur (or ball of the hip joint).
What happens if a scaphoid fracture is left untreated?
If a Scaphoid fracture does not heal, it is called a Scaphoid Fracture Non-union. If left untreated, the part of the Scaphoid that interacts with the Radius may die, which can lead to painful arthritis in the wrist, developing months to years after the initial injury.
Is a scaphoid fracture serious?
A scaphoid fracture can lead to wrist osteoarthritis, especially if the fracture is untreated and does not heal correctly.
