The subscapularismuscle is partially di\dded to give a freer exposure of the capsifle. This routeexposes, by a small incision, the site of the original tear in the capsule. Itavoids division of the deltoid and gives dependent drainage if drainage isnecessary. The relaxed portion of the capsule may be shortened by taking up a reefwith catgut or sflk sutures, \\dthout opening and exploring the joint for loosepieces of bone; the capsule may be incised transversely to its longitudinal 670 Diseases and Injuries of the Bones and Joints.

Dislocation of the elbow-joint is not infrequent, and is commonest in chil-dren. Both bones or only one bone of the forearm may be dislocated, and the dislocation may be partial orcomplete. Dislocation of Both BonesBackward (Fig. 406).—^Thecauses of backward disloca-tion of both bones of theforearm are falls upon theextended hand or twists in-ward of the ulna (Malgaigne).The coronoid process lodgesin the olecranon fossa of thehumerus. Symptoms of BackwardDislocation. — In completedislocation of both bones ofthe forearm the olecranon isvery prominent. The dis-tance between the point ofthe olecranon and the apex ofthe inner condyle is notablygreater than on the sound side; the forearm is flexed, supinated, and shorte
