9. 8. Tubercular Affection of Synovial Sheath, "Compound 



Gang'lion." — Cast in gelatine and glycerine of the front of a 

 left wrist of a woman, illustrating the above. 



" Mrs. W., aged 41, was admitted to the Royal Infirmary, Edinburgh, 

 in January 1891, complaining of pain and swelling in the palm of the left 

 hand and wrist. Two years ago there appeared a swelling on the front of 

 the wrist, unattended with pain, except undei' strong exertion. This 

 remained unchanged until five weeks ago, when a swelling on the palm of 

 the hand appeared also. The fingers became stitfer, and now she cannot 

 grasp anything. Three years ago her foot was amputated for tubercular 

 disease of the ankle. No other history of tubercle. Her family history 

 is good. Incisions were made in the wrist and palm, and gelatinous and 

 melon seed-like bodies scraped out." 



There is a distinct swelling of the front of the wrist and 

 adjacent part of the palm, with a slight constriction opposite the 

 position of the anterior annular ligament. G. C. 3371.
