The homeopathic practice of surgery : together with operative surgery . and middle fingers,make steady extension, while his other hand is pressed stronglyupon the ulnar side of the head of the radius, pushing it both out-wards and downwards. The arm had better be slightly bent, sothat the muscles may be relaxed. As the pronator teres tends todraw the bone towards the ulna, force applied between the bonesso as to separate them, and at first slightly raise the radius, mayperhaps aid your operation. 60 DISLOCATIONS—AT THE WRIST. OF THE RADIUS BACKWARDS. The head of the radius may be both seen and felt behind theexternal condyle of the humerus (see plate No. 36). The arm isnearly straight and cannot be flexed; the hand pronate and can-not be turned. The surface in front of the joint is relaxed andpresents a sudden depression just below the external condyle. Ifthe front of the radius be traced from below upwards, the fingerwill come in contact with the condyle; and if the side be traced,the finger will pass over the head on to the olecranon process. Fig. The reduction, if attempted early, is not generally very diffi-cult ; but these cases are frequently neglected so long that anyattempt to reduce will be fruitless, or result in more injury thanbenefit to the patient. Extension is to be made upon the radius,with counter-extension upon the humerus, while firm pressure ismade on the head of the bone until it slips into its place. Oneassistant can pull upon the hand, while another holds the upperarm, and the surgeon directs the movement of the bone. LUXATIONS AT THE WRIST, JOINTS OF THE HAND, &c. The wrist joint is liable to several displacements. Both ra-dius and ulna may be dislocated together, either forwards or back-wards, or each of them may be separately displaced in either di-rection, — thus making six varieties of luxation. First, Of both bones forwards : — The projection of the bones ofthe arm under the carpus or forwards, happens from falling upon DIAGNO
