Anomalies and Curiosities of Medicine [367]
happens that in avulsion of the finger an entire tendon is stripped up and torn off with the detached member. Vogel describes an instance of this nature, in which the long flexor of the thumb was torn off with that digit. In the Surgical Museum at Edinburgh there is preserved a thumb and part of the flexor longus pollicis attached, which were avulsed simultaneously. Nunnely has seen the little finger together with the tendon and body of the longer flexor muscle avulsed by machinery. Stone details the description of the case of a boy named Lowry, whose left thumb was caught between rapidly twisting strands of a rope, and the last phalanx, the neighboring soft parts, and also the entire tendon of the flexor longus pollicis were instantly torn away. There was included even the tendinous portion of that small slip of muscle taking its origin from the anterior aspect of the head and upper portion of the ulna, and which is so delicate and insignificant as to be generally overlooked by anatomists. There was great pain along the course of the tract of abstraction of the tendon.
Pinkerton describes a carter of thirty-one who was bitten on the thumb by a donkey. The man pulled violently in one direction, and the donkey, who had seized the thumb firmly with his teeth, pulled forcibly in the other direction until the tissues gave way and the man ran off, leaving his thumb in the donkey's mouth. The animal at once dropped the thumb, and it was picked up by a companion who accompanied the man to the hospital. On examination the detached portion was found to include the terminal phalanx of the thumb, together with the tendon of the flexor longus pollicis measuring ten inches, about half of which length had a fringe of muscular tissue hanging from the free borders, indicating the extent and the penniform arrangement of the fibers attached to it. Meyer cites a case in which the index finger was torn off and the flexor muscle twisted from its origin. The authors know of an unreported case in which a man running in the street touched his hand to a hitching block he was passing; a ring on one of his fingers caught in the hook of the block, and tore off the finger with the attached tendon and muscle. There is a similar instance of a Scotch gentleman who slipped, and, to prevent falling, he put out his hand to catch the railing. A ring on one of his fingers became entangled in the railing and the force of the fall tore off the soft parts of the finger together with the ring.
The older writers mentioned as a curious fact that avulsion of the arm, unaccompanied by hemorrhage, had been noticed. Belchier, Carmichael, and Clough report instances of this nature, and, in the latter case, the progress of healing was unaccompanied by any uncomfortable symptoms. In the last century Hunezoysky observed complete avulsion of the arm by a cannon-ball, without the slightest hemorrhage. The Ephemerides contains an account of the avulsion of the hand without any bleeding, and Woolcomb has observed a huge wound of the arm from which hemorrhage was similarly absent. Later observations have shown that in this accident absence of hemorrhage is the rule and not the exception. The wound is generally lacerated and contused and the mouths of the vessels do not gape, but are twisted and crushed. The skin usually separates at the highest point and the muscles protrude, appearing to be tightly embraced and almost strangulated by the skin, and also by the tendons, vessels, and nerves which, crushed and twisted with the fragments of bone, form a conical stump. Cheselden reports the history of a case, which has since become classic, that he observed in St. Thomas' Hospital in London, in 1837. A miller had carelessly thrown a slip-knot of rope about his wrist, which became caught in a revolving cog, drawing him from the ground and violently throwing his body against a beam. The force exerted by the cog drawing on the rope was sufficient to avulse his whole arm and shoulder-blade. There was comparatively little hemorrhage and the man was insensible to pain; being so dazed
