> Unsure how it works elsewhere but getting to Royal National Orthopaedic Hospital will only be possible if your trust has a contract with them or the powers that be grant a "special". They should have a contract with a hospital with a paediatric orthopaedic surgeon.
I’m unsure what trust the OP’s grandson is under either, which is why I said it’s worth a punt. What I do know is that many trusts will go to sometimes outlandish lengths to placate a persistent patient.
A couple of years ago a colleague transported a wheelchair user by ambulance from Yorkshire to London and back, to see a consultant who specialised in shoulders.
The patient had strained their shoulder and was unhappy with their GP’s advice to take ibuprofen and give it a few weeks. Second opinion demanded from another GP elicited the same response. A trip to A&E was then arranged with an identical response whereupon the patient spent a couple of days on Google and demanded a trip to London to see his eminence, the shoulder specialist. No prizes for guessing what advice was forthcoming. The patient asked to be dropped off at their local A&E on returning to Yorkshire.
This patient was a well known frequent flyer.
