<unk> s occur in three locations: (A) Distal tubercle, (B) waist, and (C) proximal pole. Fractures of<unk>  can occur either with direct axial compression or with hyperextension of the wrist, such as a fall on the palm on an outstretched hand. Using the Herbert classification system, there are three main types of<unk> s. 10%-20% of fractures are at the proximal pole, 60%-80% are at the waist (middle), and the remainder occur at the distal pole.
