Of both Radius and Ulna Backward. This accident, though attended with only a partial loss ofmotion, produces a complete change in the appearance of thejoint—(as seen in Fig. 38.) The posterior projection of theelbow is very prominent. The olecranon process is above theexternal condyle, instead of being on a level with it, as itshould be when the arm is extended. A deep hollow may befelt on each side of it; while in front, under the tendons, thecondyles appear like hard tumors. The hand and fore-armare in a supine position and can not be entirely turned. Spon-taneous rotation of the hand is almost wholly lost.

The reduction is easily effected. The surgeon places hisknee on the inner side of the elbow or at the bend of the 614 PARTICULAR DISLOCATIONS CONTINUED. arm, pressing most of the dislocated bones so as to keepthem from bearing on the end of the humerus, and to sepa-rate the coronoid process out of the posterior fossa of thehumerus and allow it to pass over the condyles—(a glance atFig. 39 will give the reason for this direction.)
