A practical treatise on fractures and dislocations . seen, ten days after the reduction of adislocation upon the ischiatic notch, the dislocation reproduced by asudden effort of the patieut to sit up ;2 indeed, it is when the limb isin a flexed position that the accident seems most likely to occur. Of course, in these remarks we mean to except those cases in which the upper margin of theacetabulum is broken off,and the head of the femurhas consequently lost itsnatural support in thisdirection. The possibility of thisaccident is also confirm-ed by the examples ofvoluntary dislocations,which I shall relate inthe last section of thischapter. The method of exten-sion recommended by , namely, withthe thigh at a right anglewith the body, has alreadybeen referred to; andthere is much reason tobelieve that, as a rule, itis preferable to extensionas practiced by Sir AstleyCooper. Nearly all sur-geons, however, have rec-ognized the necessity offlexing the thigh in cer-tain cases. Dr. Bigelow suggests that where greater force is required. Tripod for vertical extension.

UPWARDS AND BACKWARDS INTO ISCHIATIC NOTCH. 701 than can be obtained by the usual methods, a tripod should be em-ployed, as shown in the accompanying woodcut. The following case, reported to me by Dr. X. Fanning, of Catskill,N. Y., illustrates the occasional necessity of resorting to extension, andis of special interest on account of the extreme youth of the patient. Ihave referred to the same case once before. A little girl, two and a half years old, was caught under a fallingdoor on the 24th of May, 1867, but her parents suspected no injurybeyond a severe bruise until ten days later, when they consulted The left femur was then found to be dislocated upon thedorsum ilii. Dr. Fanning attempted first to reduce the dislocation bymanipulation, but he failed. He then directed the father to make ex-tension by the legs, while th
