The fractures at the near end (closer to the elbow, proximal pole) have a poorer blood supply and are less likely to heal without surgery. It may be at the far end (distal pole), in the middle (waist), or at the near end (proximal pole). Surgery can allow better “reduction” or alignment of the fracture fragments into a normal position and can increase the rate of predictable healing of the fracture.Ī scaphoid fracture can also be described by the location. Most displaced fractures benefit from surgery. These may be considered for treatment without surgery (with a cast). If the fracture is nondisplaced, it is still perfectly lined up. There are several ways to describe a scaphoid fracture. Usually it results from either direct trauma to the wrist in contact athletes, or indirectly from a fall on an outstretched hand and wrist with other sports. There are many different ways one can experience a scaphoid fracture, and the type of fracture may change how it is treated. Eighty percent of the scaphoid is covered with cartilage, such that most fractures of the scaphoid bone will extend into some joint.Ī scaphoid fracture is a common, career-threatening wrist injury that has been seen in virtually every sport.Ī scaphoid fracture is any break or crack in the scaphoid. The scaphoid is shaped like a twisted peanut and is only about 1 inch long or a little shorter. Its blood supply comes mostly from the far (distal) end instead of the near (proximal) end. The scaphoid doesn’t have a great blood supply, which is one of the reasons that the scaphoid fracture sometimes doesn’t heal. The scaphoid plays a critical role in maintaining the normal, pain-free motion of the wrist that is required with many athletic activities. This depression is called the “anatomic snuffbox.” If you press with your finger deep into the floor of the anatomic snuffbox, you can barely feel the scaphoid. If you put your thumb up in the air (like a hitchhiker) you will make a small depression at the base of your thumb. It is located in the thumb side of the wrist. The scaphoid is the most commonly fractured wrist (“carpal”) bone. These bones are connected by ligaments, making the wrist a fairly complex joint. There are 8 carpal bones: the scaphoid, lunate, triquetrum, pisiform, hamate, capitate, trapezoid, and trapezium. The wrist is a complex joint that is composed of the end of the radius (the big bone in the forearm, on the thumb side), the ulna (the small bone in the forearm, on the small finger side) as well as the carpal bones. The scaphoid is a small bone in the wrist on the thumb side.
