Dislocation of the atlo-axoid articulation (_os juguli_) he tells us threatens speedy death. The mouth of the patient is to be kept open by a wooden gag, a bandage passed beneath the jaw and held by the physician, who places his feet upon the shoulders of the patient and pressing down upon them while he elevates the head by the bandage, endeavors to restore the displaced bone to its normal position. Inunctions of various mollitives are then useful. Dislocations of the lower jaw are recognized by the failure of the teeth to fit their fellows of the upper jaw, and by the detection of the condyles of the jaw beneath the ears. The bone is to be grasped by the rami and dragged down until the teeth resume and retain their natural position, and the jaw is then to be kept in place by a suitable bandage. In dislocation of the humerus the patient is to be bound in the supine position, a wedge-shaped stone wrapped with yarn placed in the axilla, and the surgeon, pressing against the padded stone with his foot and raising the humerus with his hands, reduces the head of the bone to its natural position. If this method fails, a long crutch-like stick is prepared to receive at one end the axillary pad, the patient is placed standing upon a box or bench, the pad and crutch adjusted in the axilla, and while the surgeon stands ready to guide the dislocated bone to its place, his assistants remove the bench, leaving the patient suspended by his shoulder upon the rude crutch. In boys, Gilbert tells us, no special apparatus is required. The surgeon merely places his doubled fist in the axilla, with the other hand grasps the humerus and lifts the boy off the ground, and the head of the bone slips readily back into place. After we are assured that the reduction is complete, a strictorium is prepared, consisting of the _pulvis ruber_, egg-albumen and a little wheat flour, with which the shoulder is to be rubbed. Finally, when all seems to be going on well, warm _spata drapum_ (sparadrap) is to be applied upon a bandage, and if necessary the apostolicon ointment. Dislocation of the elbow is reduced by passing a bandage around the bend of the arm, forming in this a loop (_scapham_) into which the foot of the surgeon is to be placed for counter-extension, while with the hands extension is to be made upon the forearm until the bones are drawn into their normal position. Flexion and extension of the joint are then to be practised three or four times (to assure complete reduction?), and the forearm flexed and supported by a bandage from the neck. After a few days, Gilbert tells us, the patient will himself often try to flex and extend the arm, and the bandage should be so applied as not to interfere with these movements. Dislocation of the wrist is reduced by gentle extension from the hand and counter-extension from the forearm, and dislocation of the fingers by a similar manipulation.
