[Scaphoid fractures. Fracture types and localization].
The incidence, localization, and type of scaphoid fractures found in a well-defined population is described. Fractures of the carpal scaphoid (n = 442) of which 19 (5%) were nonunions were identified during an eight-year period. Among inhabitants living in the Odense Municipality (population at risk 170,648 in 1983 to 174,948 in 1989) 222 males and 51 females who sustained scaphoid fractures during a seven-year period were used for computation of incidence. During the survey, there was an average annual incidence of scaphoid fracture of eight per 100,000 females, and 38 per 100,000 males. The average annual incidence per 100,000 inhabitants of carpal scaphoid fractures according to the location was proximal two, middle 15, and distal six. Average annual incidence per 100,000 inhabitants of carpal scaphoid fractures according to type was transverse seven, horizontal oblique nine, vertical oblique one, avulsion/fracture of the tuberosity five, and not stated one.
