comminute

High temperatures required for reaction between components can result in loss of volatile oxides, while milling may not comminute powders sufficiently for complete reaction to occur on calcination.

For example, comminuting fractures on ribs 4–8 along the rib angle most likely are associated to shots through the scapula, whereas injuries through or near to the costochondral articulation of the first rib could also be associated to wounds of the sternum or clavicle.
