What is a Scaphoid Fracture?

The scaphoid is a small bone located just below the base of the thumb. It is a very common bone that is fractured and often caused by a fall onto an outstretched hand. Due to the anatomy of the scaphoid bone, no blood vessels supply the proximal pole of the scaphoid. This means that proximal scaphoid fractures have an increased chance of suffering mal-union or non-union (up to 8-10% of all cases).

What are the Signs and Symptoms of a Scaphoid Fracture?

+ Tenderness at the base of the thumb (snuffbox)

+ Restricted range of motion of the thumb, fingers or wrist

+ Pain with gripping

+ Pain with pushing and loading through the wrist

What is the Treatment of a Scaphoid Fracture?

Conservative management: When the fracture is at the distal end and considered non-displaced then a cast is placed on the wrist for 6-10 weeks.

Surgical management: When the fracture is at the proximal end or displaced then a surgical intervention is required. This is important as the scaphoid has a high complication rate of non-union/bone fails to heal due to its poor blood supply.
