Various treatments of a contracture of hand.
Case 486. (Duvernay, November, 1915.)
A chasseur, 22, received a bullet wound in the anatomical snuffbox, the bullet emerging under the styloid process of the radius, having traversed the back of the hand without striking bone. Healing was rapid, but the hand assumed a peculiar position. The second and third phalanges of the fingers were extended, whereas the first phalanx was flexed. The four fingers were as if glued together. Both phalanges of the thumb were flexed, the wrist was in extension, and the tendon of the palmaris seemed contractured. The fingers could not be moved and the wrist was very mobile. There was pain on attempts to move the hand passively, and small clonic contractions were made by the fingers. There were no sensory disorders, but there was a maceration of the interdigital spaces.
Mechanotherapy accelerated the contracture, and massage, motor reëducation, bromides, and sedative drugs, had no effect. Under kelene-anesthesia the contracture would disappear. In January, 1915, the hand was put up in plaster in a position opposite to the contracture. The intense pain of the first days was treated by opium. The patient was sent on leave, and, at the end of two months, the plaster was removed; but the hand at once resumed its faulty position, and attempts to alter its position again provoked pain. Elastic traction was then tried for six weeks, and the bad position was somewhat modified but not improved by hyperextending the second phalanx on the first, and putting the third in slight flexion on the second. Hot compresses were unsuccessful also. May 14, 1915, the position was still irreducible; there was no R. D. or electrical hyperexcitability. This was not a question of radial paralysis, since finger extension was distinct; nor a paralysis of the median, since the thumb was flexed. The contracture, in fact, does not affect a special nerve territory, and the disorder is in the ulnar, radial, and median territories.
