A practical treatise on fractures and dislocations . d a fracture extending through the neck, accompanied with aslight bloody effusion, but no displacement of the fragments or lacera-tion of the soft In other examples the bone is not only broken, but displaced tosuch an extent that the capsule is completely torn in two. But in a large majority of cases both the capsule and the periosteumare only partially torn asunder. The intra-capsular fracture is generally somewhat oblique, and itsdirection is usually from above downwards and from within its direction is such as to include a portion of the head;occasionally it is quite transverse. In one example of an old frac-ture I have seen the ends dove-tailed upon each other, the fracturehaving a double obliquity, and not admitting of displacement. There may occur also a species of impaction, the lower portion of 1 LExperience, March 14, 1844. 2 Colles, Dublin Hosp. Reports, vol. ii. p. 339. 3 Stanley, Trans., vol. xiii. 856 FRACTURES OF THE FEMUR, Fig. Impacted fracture within the capsule. the neck entering the cancellous structureof the head, while its upper portion ridesupon the articular surface, a circumstancewhich is well illustrated by the annexedwood-cut (Fig. 112), copied by Mr. Smithfrom a specimen in the Dupuytren Mu-seum at Paris ; or the impaction may occurwithout any degree of either upward orlateral displacement. Mr. Liston says: Even in children sepa-ration of the head of the bone may, on goodgrounds, be supposed occasionally to takeplace j1 by which we understand him tomean that a separation of the epiphysiswhich completes the head of the femur mayoccur. Mr. South relates a case in a boy tenyears of age, who had fallen out of a first-floor window upon his left hip. The limb was slightly turned out,but scarcely at all shortened. The thigh could be readily movedin any direction without much pain, but on bending the limb androtating it outwards, a very distinct dummy
