If my child needed hip surgery, I would not plan a Caribbean vacation at the same time, if I had too, I'd cancel the vacation...hip surgery isn't like pulling a splinter (Oh' ... a strawman)
Hip surgery isn't done on the fly, they are planned weeks in advance and I would re-schedule the vacation...
Are you purposely being dense or just myopic...?
I have some personal experience here..on two fronts.
1) 20 years working for a large hospital during which time I saw *every conceivable* medical scenario play out (hundreds of times) and 2) more importantly,I watched my sister and late BIL go through that *very* scenario with their 6 month old daughter.Years of TLC (along with lots of medical/surgical care) for a congenital hip abnormality.In fact,I'm watching that sister go through this *at this very moment* with another daughter (30 years old) who was just flown to Boston the other day needing repair of one of her heart valves.
Oh well,I suspect that the complexities (and the simplicity) regarding this subject are lost on you but remember,one of *my* favorite non-political bumper stickers is "Be Good To Your Kids,Someday They'll Choose Your Nursing Home"
And P.S.,Not that you'll believe me but I assure you that not all hip operations are "scheduled".
