The upper and lower extremities are more exposed and mobile than the spine and trunk and, therefore, are fractured more often than the less exposed and better protected spine and trunk. The frequency of fracture, both closed and open, is then greater for the extremities than for spine and trunk.
The statistics in this series show that the risk of open fracture is the same in 1955 as it was in 1937 (4 per cent).
More fractures are amenable to successful operative treatment and more such fractures are being treated operatively.
Fractures (new and old) have comprised approximately one third (31 percent) of the total cases seen in this practice of orthopaedic surgery and this proportion has remained the same from 1937 to 1956.
