![]() Oftentimes, the patient who has sustained a scaphoid fracture attempts to self-treat at home with rest and ice, and presents for evaluation days later because the symptoms have not improved.įor those who are evaluated at the time of injury, X rays taken in the emergency department may not show a scaphoid fracture. Indeed, the symptoms are similar, and the pain and tenderness associated with a scaphoid fracture can be subtle. Scaphoid fractures are commonly misdiagnosed as wrist sprains. Range of motion of the wrist may be slightly decreased. A scaphoid fracture will result in pain, tenderness, swelling, and bruising centered around this location. The depression in the skin that occurs at the wrist below the thumb is the snuffbox. The snuffbox, also known as the radial fossa, is located by making a thumbs up sign. The hallmark symptom of a scaphoid fracture is known as “snuffbox” tenderness. What are the symptoms of a Scaphoid Fracture? These forces can also be replicated in an athletic injury or due to trauma sustained in an automobile accident. Scaphoid fractures are caused by a fall onto an outstretched hand where the force is concentrated on the thumb, or radial side of the hand. If that supply is cut off by a fracture in the neck or proximal third of the scaphoid, the entire bone is in jeopardy, as the bone will not receive the nourishment it needs to repair itself. The blood supply of the entire scaphoid is derived from vessels entering the distal portion of the bone. Anatomically, the scaphoid is divided into thirds: the proximal third being closest to the radius of the forearm, the middle forms the neck, and the distal third articulating with other carpal bones of the wrist. The name scaphoid is derived from Greek, and means bowl or boat, which is an apt description of its shape. It is located on the radial side of the wrist, under the thumb. The scaphoid is one of the eight carpal bones which form the wrist.
