Note 39 — Chapter XXXIV · FRACTURES.
Reading edition
In supracondyloid fractures there is almost always posterior and upper displacement of the lower fragment. When the parts are found in this position, and especially when the skiagram shows the line of fracture in the usual location (from above downward and forward), the fracture should be treated by flexion of the arm in the so-called Jones’ position. By this the fragment is best restored to its proper position, being pried there by the muscular cushions of the forearm and arm. (Ashhurst.)
