Contracture: Hysterotraumatic.
Case 390. (Sollier, January, 1917.)
A sailor, 41, got hygroma of the right knee in 1915, was operated on in July, returned to his dépôt a month later, and thence to Vizille Urage by reason of contracture in extension of the right leg. It was thought he was simulating (since there was no muscular atrophy), and he was sent to the neurological center, where under anesthesia the joint was found free. This man developed, when the knee was bent, extraordinary cracklings in the joint, and he showed pain unequivocally, making a defensive movement, partly reflex, partly voluntary, when the leg was flexed beyond a certain point. There was 3.5 cm. atrophy in the thigh, a reflex atrophy due to the joint disorder. There were no other signs of hysterotraumatic contracture.
According to Sollier, the diagnosis of hysterotraumatic contractures depends upon: first, a characteristic special attitude of the contractured limb; secondly, the participation of the antagonists as a group (global); thirdly, the superposition of sensory disorder upon motor disorder (Charcot’s law); fourthly, the segmentary topography of sensory disorder; fifthly, the extension of the contractured joint; sixthly, the persistence of the contracture in the same form, whether at rest or in attempted movements; seventhly, muscular rigidity; eighthly, normal tendon reflexes; ninthly, normal electrical reactions (though R. D. is hard to determine in muscles contracted to the maximum); tenthly, special reactions during attempts to reduce, such as pains, and equal and regular resistance to changed attitude, pseudoclonus in cases of foot contracture; eleventhly, immediate reproduction of the contracture after reduction under chloroform; twelfthly, co-existence of various hysterical stigmata.
