Hi,
I don’t think the supraspinatus matters here as there is a fractured scapula!
They will need an orthopaedic opinion and the supraspinatus can be looked at down the track.
As for the supraspinatus, I don’t think there is an acute injury.
There is some chronic tendinosis for sure with a generalised loss of collagen structure and decreased echogenicity.
The echogenic areas are most likely some old granulation “scar” tissue from prior small injuries and chronic partial thickness tear injuries. I don’t think they represent hydroxyapatite as they are not visible on the plain radiograph.
This is a nasty injury.
I have often wondered why we don’t see more scapula;a fractures as when you hold the bone in your hands at one of the Canon anatomy days you appreciate how light and fragile it is.
It always feels to me that it is designed for a flying animal as it is so light weight!
Steve.
