Fracture of the coronoid rarely occurs with back-ward dislocation, but if it does occur, there will be crepitus and mobility. Frac-ture at the base of the condyles is distinguished from dislocation of both bonesof the forearm backward by the following points: in fracture there are foundthe ordinary symptoms; measurement from the condyles to the styloid processesdoes not show shortening; there is no alteration of the normal relation betweenthe olecranon process and the condyles; and the projection in front of the jointis above the crease of the bend of the Fig. 466.—Forward dislocation of the radius. Treatment of Backward Dislocation.—Reduction must be effected early indislocation of both bones of the forearm, because it will soon become impos-sible, and an unreduced dislocation means a limb without the powers offlexion, pronation, and supination. The surgeon may place his knee in frontof the elbow-joint, grasp the patients wrist, press upon the radius andulna with his knee, and bend the forearm with considerable force, the musclepulling the bones into place (Sir Astley Coopers plan). Forced flexion, tractionand extension may be tried (Fig. 465). Put the arm in Joness position fortwo weeks, and make passive motion daily after the first few days. Dislocation of Both Bones Forward.—The cause of forward dislocationof both bones of the forearm is a blow on the olecranon when the arm is is an unusual accident.
