Lance-thrust in back, rapidly healed. Paralysis of right leg, disappearing with rest and exercises. Later, psychotic symptoms, with recovery. =Case 233.= (BINSWANGER, July, 1915.) N. H., 21, a laborer, industrious and sober (mother healthy, father insane and a suicide; patient somewhat sickly in childhood after pneumonia, a good scholar) volunteered at the outbreak of the war. Early in November he was on the Eastern front. November 17 to 22 he was in a number of small reconnoitring skirmishes almost daily, as a cavalryman. On the 22d, there was a clash with a Cossack patrol of far superior numbers. Eight German horsemen cut their way through, riding about 4 kilometers back to their squadron. While dismounting, N. H. discovered that his back was wet. It occurred to him at once that he had been wounded. However, he successfully dismounted and then collapsed, feeling as if his right leg had fallen asleep. His companions found a wound in his back, which had come from a lance-thrust. The wound was bandaged. He was transported to Germany on a peasant’s wagon, the trip occupying six days, and on December 6 he came to the surgical clinic in Jena. The wound was insignificant and healed quickly. The leg remained motionless, and on December 10 the patient was referred to the nerve hospital. He was a small, slenderly-built man, with poor nutrition, weighing 108 pounds. The scar, about 1 cm. long, alongside the thoracic vertebra, was still somewhat red and but slightly sensitive to pressure. Neurologically, the knee-jerks and Achilles jerks were greater on the right than on the left, and there was on the right side a distinct patella and ankle clonus. There was no Babinski reaction on either side. The movements of the right leg were not of wide excursion, and flexion and extension of the knee and ankle-joints, while lying on the back, were slowly and hesitatingly performed, with an expression of pain, and with visible effort by the quadriceps muscles. Flexion and extension of the toes were likewise difficult, and when the toes were stretched there was a distinct contraction of the tibialis anticus. Electrically the muscles were normal. On passive motion, there was slight spastic tension in the musculature of the right leg, and the patient said he felt marked pain. In walking, the right leg was moved with a limp and with the evident design of sparing it. The knee was imperfectly bent and the sole of the foot was dragged along the ground. There were short out-throwing movements of the lower leg.
