180 Injuries of Bone. 



3. 385. Gunshot Fracture of the Tuberosities of the 



Tibia. — Upper half of a right tibia — macerated, to show the 

 effects of the above injury and the commencement of repair. 



There is an irregular aperture below the front of the inner 

 tuberosity, and another at a higher level, below the back of the 

 outer tuberosity. The front aperture is the larger, but pieces 

 of bone split off near the back aperture have been reuniting in 

 their original position, thus making it seem unduly small. The 

 bone is fissured into the knee-joint, and for about six inches 

 down the shaft. There is new periosteal bone round the seat of 

 injury and partly filling up the fissures. These changes must 

 have occupied several weeks. G. C. 3429.

3. 386. Gunshot Fracture throug-h the Tuberosity of the 



Tibia. — Upper end of a left tibia — macerated. The injury i& 

 similar to the last. 



The bullet has struck the front of the outer tuberosity 

 and has emerged at the back of the inner tuberosity, at a 

 higher level. There is a small somewhat circular aperture in 

 front and one larger and more irregular behind. A piece of 

 bone split off at the back has been attached by a wire. The- 

 splitting passed into the knee-joint and shaft. Some new 

 bone has formed round the seat of injury. G. C. 3430.

3. 387. Gunshot Fracture of the Upper End of the Shaft 

 of a Tibia. — Upper two-thirds of a right tibia and fibula — 

 macerated, with fragments wired together. 



On the inner side of the shaft of the tibia, three inches- 

 be! ow the tuberosity, there is a somewhat circular aperture, with 

 its margins bevelled towards the interior of the bone. On the 

 outer side a large irregular gap is seen, with its margins in 

 places bevelled outwards. The bone surrounding these aper-
