Fractures of the Humerus. 89 



3. 124. Ununited Fracture at the Lower End of the Shaft. 



— Left humerus of an adult woman — macerated — showing the 

 above. 



The patient, aged 40, after having been treated in the Royal 

 Infirmary, Edinburgh, for fractured humerus was discharged. On August 

 24, 1825, she was re-admitted for pain and a iluctuating swelling in the 

 region of the fracture. Next day the swelling was incised, and a great 

 quantity of thin, glairy fluid was discharged. On the 10th of September, 

 symptoms of septicaemia appeared, the wound inflamed and suppurated, 

 and on the 16th September she died suddenly, apparently much exhausted. 



The adjacent surfaces of bone are smooth, but the provisional 

 callous on the inner and front part seems to have united round 

 the bone before death. The surface of the bone above and 

 below the fracture is roughened and covered by new periosteal 

 outgrowth in a way common in septic irritation. 



This seems to have been a case of ununited fracture with 

 serous exudation round the broken ends, and septicaemia 

 following the incision. The small part of callous union pro- 

 bably occurred after the second admission to the Infirmary.

3. 125. United Fracture above the Condyles.— Adjacent 



portions of the right humerus and ulna of an adult — macerated 

 — showing the effects of the above injury. 



The bone is broken about one and a half inches above the 

 condyles. The lower fragment has been displaced forward, and 

 over-riding has occurred. 



Inflammation has ensued in and around the elbow joint, 

 and this has led to alteration of the articular surfaces and 

 anchylosis. B. C. I. 1. M. 47.
