Bullet injury of spine; bronchopneumonia: état criblé of spinal cord.
As to the development of eschars, Roussy reports the case of a lieutenant wounded September 25, 1915. There was a penetrating wound of the interscapular region. The bullet had entered on the posterior aspect of the right scapular region and had emerged at the level of the first dorsal vertebra. October 1, a neurological examination showed flaccid paraplegia, knee-jerks normal, Achilles jerk weak on the right, plantar reflexes flexor, cremasteric reflex absent on the right, and both abdominal reflexes absent. There were pains in the legs and arms. There was retention of urine with overflow. A slight dulness on the right; temperature from 38 to 39 degrees.
Four weeks later the knee-jerks had become very weak, and the Achilles jerks were now absent. There was an extensive diffuse atrophy of the lower leg and thigh muscles, and a hypesthesia of pronounced degree had developed throughout the legs, over the buttocks, and in the lumbar region. Anal and vesical sphincters relaxed; dejections voluminous; sacral decubitus as well as healed eschars. December 5, the patient was transferred to the Army neurological center; temperature rose; there was much expectoration; paracentesis yielded no fluid; pneumococcus in the sputum. Cystitis had developed despite extreme care. Extensive edema of the legs developed. There was increased dulness on the right side, coughing and dyspnea. Death, January 17.
The autopsy showed a bronchial pneumonia of the right lower lobe, confluent, imitating a lobar pneumonia. The left lung also showed extensive confluent bronchopneumonia at the base as well as disseminated areas and edema of the middle and apical portions. Infectious splenitis, large fatty liver, swollen kidneys, no pyonephritis.
The spinous processes of the 6th and 7th cervical vertebrae were injured. There was no obvious gross disease within the theca except that there was a slight adhesion between the dura mater and the anterior surface of the spinal cord at the level of the 7th cervical and highest dorsal vertebrae. There was, however, a depression on the anterior surface of the spinal cord at a lower level, namely, at the level of the 4th dorsal vertebra. Microscopic examination showed myelomalacia with small cavities in the 1st and 4th dorsal segments, suggesting the état criblé.
According to Roussy, these patients injured in the spinal region are particularly sensitive to cold and support transfer badly even when the disease is short. Such patients should be evacuated to the interior after the shortest delay possible. Sometimes these patients show rib fractures; these are in the posterior portions of the ribs and are due to the fall of the man when struck. It might be possible even that the spinal lesions should through the action of the sympathetic nervous system favor lung infection.
