Scaphoid fractures account for 71.2% of carpal fractures, mostly occurring in the waist of the scaphoid, accounting for 70% of scaphoid fractures, while scaphoid tuberosity and proximal scaphoid fractures each account for 10% to 15%. The fracture line starts from the palm and ulnar side first, and then reaches the dorsal and lateral side. It is more common in young people and rare in children. When scaphoid fractures are accompanied by other carpal fractures and dislocations, the prognosis is poor. Most of the scaphoid is covered with articular cartilage, and only the tuberosity and dorsal and lateral part of the waist have exposed bone, from which the nourishing blood vessels enter the bone and supply blood to the surrounding branches. The proximal 2/3 to 3/4 of the blood of the scaphoid comes from the blood vessels entering the bone at the waist, and the distal 1/4 to 1/3 is nourished by the blood vessels entering the bone at the tuberosity of the scaphoid. The blood vessels that enter the bone from the waist and supply blood to the proximal pole in a retrograde manner can be damaged and broken due to waist fractures, resulting in ischemic necrosis of the proximal fracture segment.
