84 Injuries of Bone. 



humerus, broken off irregularly from the shaft of the bone — 

 macerated. 



The patient, John Locke, ?et. 64, fell over a parapet at Stockbridge, 

 and besides this injury sustained a compound fracture of the elbow joint. 



The arm was amputated at the shoulder joint a few hours after the 

 accident by Sir George Ballingall, and the patient recovered without a 

 bad symptom. 



The fracture has passed between the anatomical and sur- 

 gical necks on the outer side, and through the anatomical neck 

 on the inner side of the bone, i.e. in a line corresponding to 

 that of the epiphysial junction in a young subject. The rari- 

 fication of bone round the seat of fracture makes it appear as 

 if the patient had survived the injury for some weeks, and as 

 if this piece had had a vascular supply. G. C. 744.

3. 107. Fracture throug-h the Anatomical Neck and 



greater Tuberosity. — Left humerus — macerated — showing 

 the above injury. 



The fracture, as in the previous specimen, has passed 

 between the anatomical and surgical necks on the outer side, 

 and through the anatomical neck on the inner side of the bone. 

 There has been no union, but there are indications of periostitis 

 on the upper piece at the outside, and on the lower fragment 

 down nearly to the elboAv joint. The patient had therefore 

 probably survived the injury several weeks. G. C. 918.

3. 108. United Fracture throug-h the Anatomical Neck 

 and g-reater Tuberosity. — Left humerus of an adult, 



probably a woman — macerated — showing the above. 



The line of fracture has evidently been similar to that in 

 the last two specimens, i.e., between the two necks on the outer 

 side, and along the line of the anatomical neck on the inner 

 side. The broken bone has united without thickening, but
