Crural monoplegia, tetanic. Recovery.
An ensign was wounded by a shell splinter in the right scapular region September 25, 1915. A large hematoma was drawn off and drains inserted. Antitetanic serum was given 24 hours after the trauma. The wound looked well. The patient complained merely of the heaviness of his arm, and after September 27, the temperature fell to normal. Magnesium chloride solution was applied every other day, and progress was so good that evacuation was ordered.
However, October 8, the patient suddenly began to complain of a sharp pain in the right thigh, which next day became intolerable and threw the muscles into a slight contracture, the adductors being extremely stiff. Headache developed in the course of the day, with slight stiffness of neck, exaggeration of reflexes in the right leg, and ankle clonus. Temperature: 37.6 morning, 38.5 evening. The patient was isolated and given chloral.
October 10, paroxysmal crises of pain, more marked stiff neck, and lumbar stiffness appeared, with nervousness, photophobia, and hyperesthesia to noise. The wound seemed to be doing well. Chloral was given.
Slight trismus developed October 11. The tongue became dry and the patient drank little. The condition held and the same treatments were repeated up to October 15, when the temperature fell and the contractures and pains were diminished. The chloral was continued. There were still a few cramps in the neck. October 22, however, the patient was practically well.
We are here dealing with an instance of local tetanus of monoplegic form, developing a fortnight after the wound (there is an early group developing, as a rule, from the fifth to the tenth day, and a group of later development, after the twentieth day; the interval in this case was of intermediate duration). According to Courtois-Suffit and Giroux, the differential diagnosis is not easy, since, besides tetanus, must be considered tetany, spastic monoplegia of cerebral or spinal origin, partial hemiplegia, peripheral neuritis, contractures due to bone, joint, muscle or tendon lesions, strychnine intoxication and hysterical contractures. Three cases out of six described by Routier were fatal.
Re differential diagnosis of tetanic conditions, see Courtois-Suffit and Giroux in the Collection Horizon. The cases as a rule appear in subjects that have had serum treatment, and may occur in subjects in whom no trismus ever develops (the above case showed slight trismus).
The recognition of localized tetanic contracture is based upon (a) the intensity of the contracture, which causes the limb to feel wooden (in one case the foot, leg, and thigh were welded to the pelvis like an iron bar); (b) paroxysmal contractions resembling those of tetanus, confined to one limb, and started by a variety of external causes, forming the principal symptom in the disease; (c) contracture of comparatively brief duration (hardly ever over two or three weeks). A slight fever may help in the differential diagnosis.
