Help!- Ligament at back of hock?

[1928sky]

As the title says really. Had x-rays and scans done yesterday and vet says strain of the ligament at the back of the hock but never gave a name for it! Just wondered which ligament it was! If anyones horse has had an injury like this please share.
Thank you

Proximal suspensory ligament? Runs from back of hock to fetlock? Lots of posts on this on the forum - including mine!
