The international encyclopaedia of surgery; a systematic treatise on the theory and practice of surgery . ediannerve is detached from the sheath and drawn outward by a strabismus hook(Fig. 485); the sheath of the artery is then opened ; it lies between two veins(ven?e comites). The arm is now flexed, the artery isolated, and the ligaturepassed from without inward. Sometimes the brachial artery divides into theulnar and radial arteries in the upper third of the arm; the radial, in thatcase, commonly runs more superficially and externally (upon the biceps),while the ulnar appears conspicuously small (Esmarch). Operation at the Elhoio.—The brachial artery, at the elbow, lies in the cen-tre of a triangular space, formed externally by the supinator longus, and in-ternally by the pronator radii teres.

Immediately beneath it is the artery, lying on the brachialisanticus muscle, and between the venae comites. The median nerve lies a fewmillimetres inward, and passes beneath the pronator radii teres (Esmarch). Ligation of the Radial Artery.—Although the radial artery is smallerthan the ulnar, it directly continues the course of the brachial artery, andruns in a line drawn from the middle of the bend at the elbow to the innerside of the styloid process of the radius. It is superficial in nearly all itscourse. The radial nerve lies on its outer or radial side. It has two venae-comites. Operation in the Upper Third.—Having extended the arm in a supine position,and having raised the superficial veins by compressing them above,
