Shrapnel wound above clavicle: Brachial monoplegia, partly hysterical, partly organic.
Case 426. (Babinski and Froment, 1916.)
Babinski speaks of certain symptomatic incompatibilities which emerged in the study of cases of combinations of hysteria, organic nervous disease, and the so-called physiopathic disorders. An example of such an incompatibility might be that of a patient who should, three months after a sudden hemiplegia, show complete or almost complete flaccid paralysis and but slight exaggeration of tendon reflexes—yet the Babinski reflex. Of course, the Babinski reflex would permit a diagnosis of pyramidal tract disease. Yet a sudden intense hemiplegia lasting three months, if it were merely a matter of pyramidal tract disorder, ought to show hyperreflexia of a pronounced degree as well as contracture. An example from the arm is as follows:
A soldier got a shrapnel wound in the left supraclavicular region, and had a complete paralysis of the arm, which had lasted more than a month. Electrical examination showed marked reaction of degeneration in the muscles controlled by the musculo-cutaneous nerve, as well as a diminution of electrical excitability in the muscles innervated by radial branches. On the contrary, in the circumflex territory, ulnar and median, electrical excitability was normal. There were no vasomotor disorders. The diagnosis of an association of hysteria and organic disease was made. Babinski affirmed that electrification would effect a partial cure; and in point of fact, the patient, after having submitted to the current for several minutes, was able to use all the muscles whose faradic contractility was normal or almost normal. Thus, he could raise his arm, flex the thumb, flex the fingers, close the hand, and extend the hand and fingers. Flexion of the forearm on the arm was still difficult, since there was, in fact, a reaction of degeneration in the muscles of the anterior region of the arm. The fact that the movements could be partially executed was dependent upon action of the supinator longus.
Gunshot fracture of upper arm; recovery with motor power in five weeks: Six weeks later, Erb’s palsy (plus). Hypothesis: “Reflex paralysis” preferred.
Case 427. (Oppenheim, January, 1915.)
A reservist, 26, was shot through the middle of the left upper arm, sustaining an oblique fracture of the humerus, August 26. The external wounds healed in a month; the fracture somewhat later. The left arm was at first stiff and motionless, but in five weeks it could again be moved. Pains disappeared with return of motility.
About the middle of November the arm began to lose power to move again, especially the muscles of the upper arm. November 20, the patient showed atrophic paralysis (left deltoid, biceps, brachialis internus, and supinator longus) suggesting at first glance the appearance of an Erb’s palsy; but the triceps and the adductor of the upper arm were also unable to move and there was a slight paresis in the distal muscles of the extremity. There were no pains or other objective disorders.
The diagnosis of subacute poliomyelitis was considered. Electric excitability, however, was found to be normal, both faradically and galvanically.
