In indirect violence, such as follows dancing, jumping, or sudden twists of the foot, the fifth metatarsal bone is the one most often involved. There is but little tendency to displacement except when several bones are broken at the same time, and then it is toward the dorsum of the foot. The diagnosis in fractures produced by direct violence is made from the following: presence of severe localized pain; swelling; and, not infrequently, crepitus and abnormal mobility. In those fractures due to indirect violence (second, third and fifth metatarsals), there is pain when the patient endeavors to put pressure upon the toes or tries to invert the foot. The usual signs of fracture are absent. A skiagraph should be made in every case. Fracture of the metatarsal bones is liable to be followed by traumatic flat foot, on account of the sinking of the arch, or painful large calluses forming on the sole of the foot may interfere with walking. +Treatment.+ The treatment in such fractures is by immobilization in a posterior metal or plaster splint, for four weeks. If there is continual pain upon walking after the injury, a steel insole will often give relief. The treatment of compound fractures of the metatarsal bones does not differ from that of other bones. +Dislocations.+ A dislocation is a displacement from each other of the articular ends of the bones which enter into the formation of a joint. A diagnosis can usually be made from certain objective and subjective symptoms, taken in conjunction with an accurate history of the manner in which the accident occurred. Examination should be made in a systematic manner in every case, us follows: (1) _Inspection._ The limb should be first inspected to note the position, the alterations of contour, or of the axis of the limb, or the projection or absence of certain bony prominences. The position is often so characteristic that a diagnosis can be made by inspection alone. (2) _Palpation._ By this one can learn the relation of the displaced articular ends to each other, unless the swelling is too great, or the patient is very stout. This method also enables one to ascertain the absence of normal prominences or the presence of abnormal ones. The end of the displaced bone may be felt in an abnormal position. (3) _Measurement._ The limb may only appear to be or is actually shortened. In the latter event the normal measurements between bony prominences will be altered. (4) _A skiagraph_ should be made in all doubtful cases to confirm the diagnosis of dislocation, and also to ascertain whether there is an accompanying fracture. When the patient is stout, or when considerable swelling exists the use of the X-ray is of especial value.
