Distortions from Injury. 573 



entirely on the balls of his toes. An ulcer, which formed below 

 the heel, had given him so much trouble, that he wished the foot 

 amputated. 



The bones were atrophied and fatty, see ^No. 6. 15. 

 The skin over the forepart of the foot and toes is coarse. 

 The papillae are enlarged, especially on the second toe, which 

 has a club-shaped extremity, and a very warty surface.

11. 7. Distortion of Foot by Compression. — Plaster cast of 



the right foot of a Chinese lady, showing distortion, artificially 

 produced. 



The four outer toes are doubled under the sole. The 

 metatarsal and central tarsal bones are forced upwards, so that 

 the ball of the great toe nearly touches the heel, and the usual 

 arch of the foot is now represented by a narrow cleft in front 

 of the heel. The bones generally, but especially the tarsal 

 bones, have evidently been stunted in their growth.

11. 8. Hand distorted from Injury to the Ulnar Nerve. 



— Plaster of Paris cast of a right hand, illustrating the above. 



By a machinery accident, 5^ years before the cast was taken, the 

 hand and forearm of the patient, a woman, bad been severely lacerated, 

 and the Thumb destroyed. Her hand remained from that time stiff, 

 powerless, and very painful, and gradually assumed this shape. 



The exaggerated extension of the first phalanges, with 

 flexion of the last two, is, as Duchenne pointed out, due to atrophy 

 of the intrinsic muscles of the palm, following paralysis of the 

 ulnar nerve. The deformity is known as "main au Griffon," 

 or "Claw hand." G. C. 3111.
