Wound of left foot: ACROCONTRACTURE. Psychoelectric cure, about seven months later, at one sitting, except for some residuals that cleared shortly afterwards.
A soldier, 21 years, was observed at the Centre Neuropsychiatrique, August 30, 1916. He had been wounded in battle, March 16, 1916, near the left internal malleolus. Infection followed and inguinal adenitis, for which he was in hospital a month.
Even before the abscess began, the foot had begun to twist inward. After the abscess had been cured, a contracture set in permanently, and at entrance to hospital was irreducible. The knee-jerk and Achilles jerk were more active on the side of the equinovarus contracture. There was even a slight amyotrophy of the calf. There was no appreciable vasomotor disorder. The foot and lower part of the leg were a little warmer on the left side.
Cure followed a single sitting with psychoelectric treatment, at least so far as the contracture went. Pain and swelling remained in the evening, followed by fatigue. The patient was discharged cured, October 12, 1916.
Hysterical pes equinovarus shows the foot immobile as if frozen (figé). The foot is extended with the toes lowered and the internal border incurved, as if revolved about the axis of the leg. The surface of the sole is directed inwards and much furrowed. The tendon of the tibialis anticus is very prominent. The internal malleolus is hardly visible, while the head of the astragalus is easily made out. No passive movement is possible and the tibiotarsal and mediotarsal joints are quite out of function. Upon palpation, the excessive contracture of the anterior muscles of the leg is striking. Upon request to move the foot, the foot is not moved, but muscles of the lower leg may contract, and even those of the thigh.
There were no sensory disorders in the present case, though they often do occur in this form of acrocontracture. It is doubtful whether the skin changes sometimes seen, such as hypothermia, hyperidrosis, cyanosis, and glossiness are due to circulatory disorder induced by the contracture or to the prolonged immobility. It has been proved by Meige, Benisty and Lévy, that even in a normal subject prolonged immobility may cause a difference of temperature of several degrees. Circulatory disorders sometimes cease immediately upon cessation of the contracture. Roussy and Lhermitte insist upon energetic and early treatment of these psychoneuropathic acrocontractures, which are apt to proceed less favorably than the acroparalyses. If not treated energetically and early, actual nerve, tendon, and bone lesions may ensue.
