| In the Theromorpha it has an acromial process with which the precoracoid articulates, and it is very large in Dinosauria. |
| However, it must be noted that all os acromiales and acromial fractures healed completely. |
| There are normally 3 acromial ossification centers that fuse between 22 and 25 years of age. |
| This may occur as the result of malunion following acromial or humeral greater tuberosity fractures or from osteophytes which project into the subacromial space. |
| Acute displaced symptomatic fractures distal to the acromial angle can be successfully treated with Kirschner wire and tension band wiring. |
| The acromial epiphysis can be identified in isolation from mid to late puberty. |
