Hi
I have used them before, but to see a canine opthalmologist, so can't really comment about them in any other field.
I don't really know what a coronoid process is, but if this is orthopaedic surgery (as I am assuming from the 'fracture' bit) I would recommend Gary Clayton-Jones, in Tenterden in Kent (he can also be seen for an assessment in Bayswater). IMO he is the finest orthopaedic surgeon in the country and was the BVA's chief scrutineer for hip scoring. He replaced both my first German Shepherd's hips and also repaired a cruciate ligament on my little mongrel that had been done locally and gone wrong. I don't know where you are (but obviously in the South East). I am quite sure that your vet will know of Clayton-Jones, whose surgery in Tenterden is called the Highland Surgery.
The other upcoming ortho surgeon is Noel Fitzpatrick (who has pioneered some prosthetics for dogs) and is the one treating Chris Evans dog. I have heard great things about him, and he is in the south east too.
Hope this helps.
