Raestock (Deutsche Militärärztl. Zeitschrift, 1887, p. 331) has, by means of experiments upon the cadaver, shown that this accident occurs in forced pronation while the radius is resting upon the ulna at the point where the former crosses the latter, the ulna acting as a fulcrum. The head of the radius is pressed against its capsule and tears the latter. More rarely, the accident may occur in forced supination, by pressing the bone against the posterior edge of the ulna, the head of the radius being luxated through a rent made by a rupture of the external lateral ligament between the outer and inner sides; upon pronating the hand, this outward dislocation is converted into a forward one. The annular ligament is either torn or else the coronoid process of the ulna is broken. In either case the interposition of the annular ligament in the fold of the joint becomes an obstacle to reduction. In the experiments as detailed, great force was necessary in the production of the luxation. Should active and passive movements, manipulation, etc., fail to remove the obstacles to reduction, the author advises a resort to secondary resection of the displaced head of the radius; this, with proper precautions, is certainly a most wise and rational procedure. CHOLECYSTOTOMY, WITH LIGATURE OF THE CYSTIC DUCT. Zielewicz (Centralblatt f. Chirurgie, No. 13, 1888,) proposes in addition to the so-called “ideal” method of Spencer Wells, that of suturing the gall bladder to the abdominal wound, to ligate the cystic duct, in order to insure the patient against the return of the biliary lithiasis. The only case in which he has tried it was one in which an attempt was being made to perform cholecystectomy, but the adhesions between the gall bladder and liver were so dense and unyielding as to render the removal impossible, on account of severe hæmorrhage. He therefore passed two ligatures around the cystic duct and divided the latter between them. The gall bladder was then fastened to the abdominal wound, incised and emptied of its contained calculus and biliary secretion. The patient made a good recovery, a fistula remaining, of which the writer says, that “after a time it was almost closed.” The author claims for this operation the following advantages: 1st. Rapid healing without a resulting fistula. The gall bladder is practically removed from the organism. With appropriate after treatment, its secretion soon ceases, and it becomes obliterated. 2d. The operation is simple and less dangerous than cholecystectomy, and gives the same results.
