FISSURED FRACTURES. 



3. 1 . Fissured Fracture of both Parietal Bones. — Calvarium 



of an elderly person — macerated — showing the above fracture, 

 and two trephine openings on the right side. 



The patient had fallen from a great height. When taken to the 

 surgeon he was insensible, and had an extensive effusion of blood over the 

 right parietal bone. When the bone was exposed by an incision a fissure 

 was seen, and first the posterior, then the anterior trephine hole was made 

 in the hope of relieving pressure from blood clot. However, "the patient 

 continued to snort in a state of complete insensibility, and died." 



On the right side the fissures radiate in three directions 

 from about the centre of the parietal eminence. The widest 

 fissure runs down to the centre of the squamous suture. 

 Another fissure, more on the outer than on the inner table, runs 

 forward to the coronal suture, while the third, running back- 

 wards over the trephine openings, does not extend beyond the 

 posterior one. 



On the left side a fissure runs from above the parietal 

 eminence towards the posterior inferior angle of the bone.
