White has described a case in which a nail broken off in the foot, separated into 26 splinters, which, after intense suffering, were successfully removed. There was a case recently reported of a man admitted to the Bellevue Hospital, New York, whose arm was supposed to have been fractured by an explosion, but instead of which 11 feet of lead wire were found in it by the surgeons. The man was a machinist in the employ of the East River Lead Co., and had charge of a machine which converted molten lead into wire. This machine consists of a steel box into which the lead is forced, being pressed through an aperture 1/8 inch in diameter by hydraulic pressure of 600 tons. Reaching the air, the lead becomes hard and is wound on a large wheel in the form of wire. Just before the accident this small aperture had become clogged, and the patient seized the projecting wire in his hand, intending to free the action of the machine, as he had previously done on many occasions, by a sharp, strong pull; but in so doing an explosion occurred, and he was hurled to the floor unconscious. While on the way to the hospital in the ambulance, he became conscious and complained of but little pain except soreness of the left arm about the elbow. The swelling, which had developed very rapidly, made it impossible for the surgeons to make an examination, but on the following day, when the inflammation had subsided sufficiently, a diagnosis of fracture of the bones of the arm was made. There was no external injury of the skin of any magnitude, and the surgeons decided to cut down on the trifling contusion, and remove what appeared to be a fragment of bone, lodged slightly above the wrist. An anesthetic was administered, and an incision made, but to the amazement of the operators, instead of bone, a piece of wire one inch in length and 1/8 inch in diameter was removed. On further exploration piece after piece of the wire was taken out until finally the total length thus removed aggregated 11 feet, the longest piece measuring two feet and the shortest 1/4 inch. The wire was found imbedded under the muscles of the arm, and some of it had become wedged between the bones of the forearm. Probably the most remarkable feature of this curious accident was the fact that there was no fracture or injury to the bone, and it was thought possible that the function of the arm would be but little impaired.
Tousey reports a case of foreign body in the axilla that was taken for a necrotic fragment of the clavicle. The patient was a boy of sixteen, who climbed up a lamp-post to get a light for his bicycle lamp; his feet slipped off the ornamental ledge which passed horizontally around the post about four feet from the ground, and he fell. In the fall a lead pencil in his waistcoat pocket caught on the ledge and was driven into the axilla, breaking off out of sight. This was supposed to be a piece of the clavicle, and was only discovered to be a pencil when it was removed six weeks after.
There are several diseases of the bone having direct bearing on the anomalies of the extremities which should have mention here.
Osteomalacia is a disease of the bones in adult life, occurring most frequently in puerperal women, but also seen in women not in the puerperal state, and in men. It is characterized by a progressive softening of the bone-substance, from a gradual absorption of the lime salts, and gives rise to considerable deformity, and occasionally to spontaneous fracture.
Rachitis or rickets is not a disease of adult life, but of infancy and childhood, and never occurs after the age of puberty.
It seldom begins before six months or after three years. There are several theories as to its causation, one being that it is due to an abnormal development of acids. There is little doubt that defective nutrition and bad hygienic surroundings are prominent factors in its production. The principal pathologic change is seen in the epiphyseal lines of long bones and beneath the periosteum. Figure 213 shows the appearance during life of a patient with the highest grade of rachitis, and it can be easily understood what a barrier to natural child-birth it would produce. In rachitis epiphyseal swellings are seen at the wrists and ankle-joints, and in superior cases at the ends of the phalanges of the fingers and toes. When the shaft of a long bone is affected, not only deformity, but even fracture may occur.
Under these circumstances the humerus and femur appear to be the bones most likely to break; there is an associate deformity of the head, known as "craniotabes," together with pigeon-breast and various spinal curvature. The accompanying illustration is from a drawing of a skeleton in the Warren Museum in Boston. The subject was an Indian, twenty-one years of age, one of the Six Nations.
His mode of locomotion was by a large wooden bowl, in which he sat and moved forward by advancing first one side of the bowl and then the other, by means of his hands. The nodules or "adventitious joints" were the result of imperfect ossification, or, in other words, of motion before ossification was completed.
