Surgery; its theory and practice . The vertebrae above theinjury are dislocated forwards, as thearticular processes being fractured andthe intervertebral cartilages torn, nothing remains to keep themin position. 2. In fracture from indirect v\o\enct (Fig. 125), suchas may be received in a fall from a height upon the head, orcatching the head whilst passing under an arch, or from a weightfrilling upon the head or shoulders, the spine is bent violently for-wards, crushing the anterior j)art of the column and tearing theposterior asunder. Here one or more of the bodies and inter-vertebral cartilages are crushed between the vertebrcC above andthe vertebrae below, one of the fragments of the fractured bodybeing frccpiently driven backwards into the vertebral canal, whilstthe arches and the spinous and articular ])rocesses are wrenchedasunder. Fracture of the sternum is occasionally combined withthis injury, in consequence, it is said, of the chin coming intoviolent contact with the sternum as the spine is doubled Fracture-dislocation of thespine. (.St. BartholomewsHospital Museum.) FRACTURE DISLOCATION. 365 Condition of the spinal cord.—The importance of fracture-dis-location of the spine lies not so much in the fact that the vertebraeare fractured as that the cord is generally injured. When thevertebrse are not displaced, the cord may at times altogetherescape. More commonly, however, it is compressed, or, perhaps,completely divided, or again so bruised that it rapidly undergoesinflammatory softening. When the injury is situated below thesecond lumbar vertebrce, the cord necessarily escapes as itterminates at that spot, but the nerves of the cauda eqaina maythen be injured. Signs and symptoms.—The local signs are often but littlemarked. There may be pain at the seat of injury, or some in-equality in the spinous processes; but as often as not these areabsent. The general signs depend upon the condition of thecord, and none will be present when it has escap
