234 Diseases of Bone. 



Amputation. — The outer half of the previous speeimeK> 

 with the fibula — macerated, showing the above. 



New bone is seen to have been developing on the surface 

 of the shaft of both bones, but especially of the tibia. From 

 the history of the case, it is evident that this new bone must 

 have developed in about three weeks. There is no pei'ceptible 

 change in the bony texture of the medullary cavity.

6. 81. Acute Suppurative Osteo-myelitis of the Tibia — 



Amputation. — Water-colour drawing, by John T. Kelly, of 

 Nos. 6.80 when fresh, to show the distribution of the pus in 

 the medullary cavity. G. C. 3585. 



//. Where the chief changes are in the form of rarefaction and absorption,. 

 i.e. a septic form of " Caries." 



6. 82. Acute Suppurative Osteo-myelitis of the Neck of 



the Femur. — Section of the upper end of the right femur of 

 a child, showing the effects of a recent case of the above. 



The patient was a girl aged about eleven years, who haid beerk 

 brought up in the workhouse, and was delicate and ill-nourished. She 

 developed symptoms of very acute synovitis of the hip, with great pain, 

 following a slight injury. In a few days tlie pain subsided, and a large 

 abscess formed round the hip, and projected at the back. It was opened 

 and drained, but the child died suddenly next day, apparently from a 

 clot in the heart. No post-mortem examination could be obtained. 



The specimen shows that the bone has been opened out 

 and softened on the front of the neck within the capsule. 

 This accounts for the synovitis, which must have been suppura- 

 tive. Had the child lived, necrosis of the part below the upper 

 epiphysis might have followed. G. C. 33119'.
