Using a screw placed in the central axis of the scaphoid into the subchondral bone. Using a supplementary K-wire transfixing the distal pole of the scaphoid to the capitate.

Scaphoid Fracture. Matthew J. Scaphoid Fractures are the most common carpal bone fracture, often occurring after a fall onto an outstretched hand. Diagnosis can generally be made by dedicated radiographs but CT or MRI may be needed for confirmation. Treatment may require a prolonged period of cast immobilization, percutaneous surgical fixation, or open reduction and internal fixation.
Anatomic location. Historically the distal pole is most common location in pediatrics due to ossification sequence, however more recently waist fractures have become most common. Associated conditions. Blood supply. See Wrist Ligaments and Biomechanics for more detail. Because there is no visible deformity and no difficulty with motion, many people with this injury assume that it is a wrist sprain. Unfortunately, delaying treatment can cause problems. Visit a hand surgeon as soon as possible if you think you might have fractured your wrist.
Diagnosis A scaphoid fracture is usually diagnosed by an x-ray of the wrist. However, x-rays do not always show scaphoid fractures. If you are tender directly over the scaphoid bone which is located in the hollow at the thumb side of the wrist as shown in Figure 2 , your healthcare provider might recommend wearing a splint to be safe. If pain persists, a follow-up exam and x-ray in a week or two can be used to diagnose.
If the scaphoid is broken, the few tiny blood vessels that supply the bone with nutrients can be damaged. Because blood supply is needed to heal a fracture, the scaphoid often takes a long time a few months to heal. If the scaphoid fracture is non-displaced bone has not moved out of place at the fracture , it usually can be successfully treated with a cast.
The symptoms of a smith fracture are similar to other types of fractures. There is usually immediate pain, tenderness, bruising, and swelling. There are two main types of cast, known as plaster casts and synthetic casts. Bone grafting, or transplanting of bone tissue, is used to fix damaged bones or problem joints.

Medically reviewed by William Morrison, M. What happens in scaphoid fracture? What causes a scaphoid fracture? This means that you can return to your usual activities more quickly.
For example, if you are an athlete, a musician, or if there is another reason why you have significant pressure to return to high-level activity quickly, this treatment option may be a consideration.
However, this does mean going through a surgical procedure that does carry some small risks. A scaphoid break fracture will usually heal well if it is recognised and treated early. However, occasionally, complications can occur after a scaphoid fracture.
These can include the following:. Delayed union occurs when the scaphoid bone has not healed completely after four months of being treated in a cast. Non-union occurs when the scaphoid fracture has not healed at all. In non-union, the bony fragments are still completely separated.
Delayed and non-union may be more likely if treatment of a scaphoid fracture is delayed for some reason. So, this is the main reason why a scaphoid fracture needs to be recognised and treated promptly. However, the exact position of the fracture in the scaphoid bone, whether the fracture is displaced of not, and whether or not there is avascular necrosis see below , can also affect the healing of a scaphoid fracture. If delayed or non-union occurs, various treatments may be suggested, including wearing a cast for a longer period or surgery to help join the bone fragments together.
Surgery may involve a bone graft to help with fracture healing. This is a procedure where bone tissue is taken from another area of bone in the wrist and inserted into the fracture site.
This occurs when the fragments of the scaphoid bone heal in an incorrect position - for example, at a slight angle. If this happens, it may affect the movement of the wrist and lead to pain and problems gripping and holding objects. Malunion may be seen on an X-ray or scans of the scaphoid bone.
Surgery is usually needed to correct this complication. The scaphoid bone is re-broken, aligned correctly and a bone graft used to correct the deformity and encourage healing. Most commonly, a fracture occurs at the narrowest part of the scaphoid known as the waist. This is where the blood supply enters the scaphoid bone. So, there is a risk that if you have a fracture in this area, it can sometimes stop the blood supply to part of the scaphoid bone, leaving part of the bone without a blood supply.
This means that the scaphoid will not be able to heal properly and part of the scaphoid bone 'dies', collapses and breaks up. If it occurs, avascular necrosis can be seen on an X-ray of the scaphoid bone some months after the initial injury. However, avascular necrosis does not occur with all fractures around the waist of the scaphoid.
Osteoarthritis can develop some time after a scaphoid fracture in some people. It is more likely if there have been complications of non-union, malunion or avascular necrosis. J Wrist Surg. Epub Jul Arch Orthop Trauma Surg.
