There are eight small bones within the wrist. A commonly broken bone is the scaphoid bone, which is shaped like a kidney bean and can be tricky to heal.
Young males tend to get this injury and the injury is associated with a fall on an outstretched hand.
Presenting late, smoking and fractures close to the radius (proximal pole fractures) have a higher incidence of not healing (non-union). Sometimes, if left untreated chronic injury can lead to arthritis of the wrist.
Early identification and cast treatment can lead to good results in 85% of fractures at the waist (middle) of the bone. Some will still require surgery and a small portion would require immediate surgery.
