REGIONAL ANESTHESIA Ulnar Block at the Elbow.—With the patient l>ang in the recumbentlateral position, on the side opposite the one to be injected, and thearm to be injected resting alongside of the body, the groove betweenthe internal condyle of the humerus and the olecranon (epitrochleo-olecranian groove) is defined by palpation. Just above the groovethe ulnar nerve is located and firmly held with the overlying structuresbetween the thumb and index-finger of the left hand, to prevent itfrom moving. Needle No. 2 (5 cm.), connected with the syringe con-taining 3 of the 2 per cent, solution, is inserted through a whealraised at the summit of the fold thus produced, and is advanced towardthe nerve in a direction almost parallel with Fig. 170.—Ulnar block at the wrist: 1, Anterior route; 2, lateral route. As soon as paresthesias are obtained the solution is injected withoutmoving. Intraneural injection is here rendered easy, since the nerveis held in position while it is approached by the point of the , as already stated, paraneural injections are sufficient for surgicalpurposes, provided the anesthetic fluid is deposited beneath the deepfascia in close proximity to the nerve. In a few cases the ulnar nerv^e is an occupant of the epitrochleo-olecranian groove only in the position of extension of the forearm,passing in front of the internal condyle as soon as the forearm is nerve should, therefore, be searched for, grasped, and injected whilethe forearm is in extension.
