Necrosis from Seijtic Wounds. 27 o 



6. 179. Septic Osteo-myelitis and Necrosis following- 

 Compound Fracture. — Lower two-thirds of the shaft of th 

 left tibia of a boy (epiphysis wanting) — macerated, illustrating 

 the above. 



There is a necrosed portion at the upper end in process 

 of separation. Some new periosteal bone has been thrown out 

 on the shaft below. B. C. i. 5. M. 24. 



6. 180. Septic Osteo-myelitis and Necrosis following- 

 Compound Fracture. — Greater part of a broken tibia 

 — fragments wired together — and lower end of fibula — 

 macerated, illustrating the above. 



The greater portion of the upper fragment of the tibia is 

 irregularly pitted on the surface, and apparently has been in 

 process of separation from the rest. A mass of irregular bone,, 

 chiefly of new formation, lies on the outer side between the two^ 

 fragments. Xear the seat of fracture the lower fragment has 

 new bone developed on its anterior and inner aspects, but not 

 behind. The fragment of the fibula shows an area of necrosis- 

 at the seat of fracture, and a slight periosteal crust below.

6. 181. Septic Osteo-myelitis and Necrosis of the Humerus 

 after Amputation— Pyaemia — Death.— Sections of the 



upper half of a humerus — partially macerated, and in spirit, to 

 illustrate the above. 



The patient was a man aged 21, whose forearm forms the specimen 

 No. 6. 111. He died of pyremia after amputation above the elbow. 



The greater part of the shaft has necrosed, and over the 

 surface of this part, but separate from it, a thin shell of new 

 periosteal bone has been formed. It may be noted that the 

 granulations on the deep or inner surface of this new shell 

 have attacked the outer surface of the necrosed shaft. The 

 upper end of the shaft is rarefied, and has evidently been
