530 Diseases of Joints. 



7. 244. Tubercular Disease, with Destruction of the 



Bodies. — Right half of the previous specimen, similarly prepared. 

 The piece of bone representing the fused spines is well 

 shown. G. C. 3244. 



Presented by Johnson Symington, F.R.C.S.E., 1891. 



f. Specimens illustrating spontaneous cure, more or less complete. 



7. 245. Tubercular Disease, partially cured by Anchylosis. 



— Four lower dorsal and two upper lumbar vertebrae — macerated, 

 illustrating the above. 



The spine is bent forward, and the tenth, eleventh, and 

 twelfth dorsal bodies are anchylosed into a common mass. This 

 mass has been in turn attacked, and its surface shows large 

 rounded depressions and excavations. The body of the first 

 lumbar vertebra, and slightly also that of the second, is 

 similarly eroded. The articular processes are all more or less 

 anchylosed. B. C. i. 3. M. 53. 



7. 246. Tubercular Disease, partially cured by Anchylosis. — 



Last cervical, dorsal, and upper three lumbar vertebrae — 

 macerated. 



" A great abscess covered these bones, and the patient died of 

 hectic as it appeared." 



" Some of the vertebrae are united together by bone, 

 a small part of the third vertebra remains, the sixtli and 

 seventh are much destroyed, the ninth and tenth also, and the 

 heads of the ribs have partaken of the disease, some of them 

 being carious, others united together." 



The spine is uniformly bent forward. A bridge of 

 bone unites partially the eleventh and twelfth dorsal, also the 

 twelfth dorsal and first lumbar vertebrae. The anchylosis 

 represents an attempt at cure. B. C. i. 3. M. 51. 



7. 247. Tubercular Disease in Process of Cure. — Upper ten 



dorsal vertebrae — macerated, illustrating the above.
