Multiple wounds and bullet wound of palm: ACROPARALYSIS. Cure, five months.
Case 250. (Roussy and Lhermitte, 1917.)
A patient was observed at Villejuif, February 5, 1915. He had been wounded, January 2, 1915, and showed scars of a bayonet wound on the anterior surface of the right thigh, of a lance wound on the dorsal surface of the right foot, and of a bullet wound in the palm of the left hand.
There was left wrist drop with fingers extended. On the sensory side, there was a glove anesthesia and analgesia up to the bend of the elbow. The right leg showed a paresis and contracture, but there were no sensory disorders in the legs. Reflexes were normal. The patient was discharged cured, in May, 1915 (psychoelectric method).
This is an example of the so-called acroparalyses, paralyses limited to the hand or foot, many of which have developed in this war, after grazing wounds or more severe injury. More rarely they appear as if spontaneously. Sometimes they are preceded by slight arthralgia or vague pains.
The condition in the hand suggests a radial paralysis. The patient is unable to flex his fingers, though he probably is able to make some movements with his thumb. Sometimes, on request to move the hand, a series of coarse oscillations follows, somewhat like a tremor. These oscillations are, according to Roussy and Lhermitte, apparently pathognomonic, and depend upon the contraction of the muscles antagonistic to those whose movement has been requested. These antagonistic muscles, themselves entirely incapable of voluntary movement, are seen to be contracting effectively and jerkily to meet the action of the agonists, also seen making jerky movements. If the forearm is moved passively and rapidly, the hand flops about inert, like the hand of a marionette, although not to the degree of hypotonia in organic paralysis. The hand is often cold, moist, and cyanotic, and even possibly analgesic and hypesthetic.
