A scaphoid fracture is a break of the scaphoid bone in the wrist. Symptoms generally includes pain at the base of the thumb which is worse with use of the hand. The anatomic snuffbox is generally tender and swelling may occur. Complications may include nonunion of the fracture, avascular necrosis, and arthritis.
Scaphoid fractures are most commonly caused by a fall on an outstretched hand. Diagnosis is generally based on examination and medical imaging. Some fractures may not be visible on plain X-rays. In such cases a person may be casted with repeat X-rays in two weeks or an MRI or bone scan may be done.
