A practical treatise on fractures and dislocations . found the arm perfect in all respects,except that it was not quite as strong as before; the lower extremityof the ulna was preternaturally movable, and occasionally he felt asudden slipping in the radio-carpal articulation. Pathological Anatomy.—In the examples of compound or compli-cated dislocations, which alone have been exposed by dissections, theposterior and lateral ligaments have been found extensively torn, asalso frequently the anterior ligament, with or without separation ofthe radial or ulnar apophyses; the extensor muscles torn up from thelower part of the forearm and displaced; the first row of the carpalbones lying underneath the tendons, and upon the bones of the fore-arm, sometimes having been carried directly upwards, sometimes up-wards and a little inwards, and at other times upwards and outwards;the arteries and nerves have occasionally escaped serious injury, butmore often they have been displaced, bruised, or torn asunder. 610 DISLOCATIONS OF THE WRIST,Fi2\ Dislocation of the carpal bones backwards. (From Fergusson.) Such are, briefly, the pathological circumstances which may besupposed to exist, also, in a lesser or greater degree, in nearly allcases of simple dislocations. In compound dislocations, however, the muscles, or rather the ten-dons, are twisted, torn, and thrust aside, producing very extensivelesions among the deeper structures of the forearm and hand beforethe integuments can be made to yield. On the 2d of May, 1852, Silas Usher, get. 54, had his right armcaught between the bumpers of two cars, bruising the hand and dis-locating the carpal bones backwards, the radius and ulna being thrownforwards and pushed, completely through the skin into the palm of thehand. Most of the flexor tendons had been merely thrust aside, but-one or two were torn asunder; the median nerve was torn off, but theradial and ulnar nerves were apparently uninjured, and there wasno fracture.
